Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

My dearest friends, mush lovers and fellow mycologists, welcome back to another edition of Wyco Wednesday! I took some time off last week for my anniversary, got caught up on some mush needed organization, and got ahead on restocking some of the more popular varieties, while adding 5 new ones to the library! Thank you so much to everyone who wished us a happy anniversary and were patient during an off week! And to everyone who added a note on your last order about something positive in your life...it truly warmed my heart. I know it's easy to focus on all the surprises 2020 has gifted us so far, but it really put a smile on my face to see the highlights of what good has happened in everyone's life recently. Keep that positivity flowing! Also, if anyone added a note in the "feedback" section, instead of the "notes" with the transaction, unfortunately I was not getting those messages. If you were expecting a freebie with your happy note but were left out due to the feedback vs. note issue, please let me know and I'll have something on the way to you STAT!
In other news...gourmets are....still coming. Unfortunately, that's all I have for you guys at the moment, as some personal issues are delaying the process just a bit. A couple of weeks ago, I promised I would have a concrete date for when these gourmet liquid cultures will roll out, and I'm sorry I was not able to see that promise through. My gourmet grower had some unexpected life stuffs thrown his way, and needs to take care of some things for his family before resuming the process. I, as well as most of you in the community, recognize the importance of mental health and work/life balance as a priority over any work or hobby related activities. We appreciate your patience, and will have an update as soon as humanly possible! No matter how many curve balls 2020 tries to throw, we will come out of this better and stronger than ever! GOOD WILL PREVAIL.
To ensure quality specimens and packaging, and due to the onslaught of orders on Wednesday's, all orders placed on Wednesday's will be shipped on Thursday and Friday of that week. You will receive an email notification with a tracking link when your order ships. I appreciate your patience so hard!
The first 10 orders placed after this post (Order #12673-12682) will receive a FREE (very small) mushroom hand painted canvas! As with any of the artsy fartsy crafty thingies, DO NOT have high hopes for these items. I'm trying out something new each week to work on my own work/life balance struggles, and want to share some of my creations with you. Unfortunately, I am not such a creative person, and it shows. Throw it away, laugh, do what you wish with them, but know that when I'm making them, I'm in a meditative mindset, thinking about how all of you have blessed me and allowed me to continue living my dream. I hope this gives some of you a smile or mush needed pick-me-up on a rough day, and I encourage you to pay it forward, and make someone else's day too. We're all in this together :)
P.S. This week's craft was chosen based on a poll I posted on the MW sub. Next week will be the runner up: resin crafts! Check back on the sub soon for another poll, or comment with what you'd like to see coming up!
ALSO...in addition to the first 10 promo, and going with tradition the past couple months, any order number ending in 7, 1, or 5 on 7/15 will also get a FREE bonus unlisted syringe not available in the shop with their order!
FINALLY...and this is the big one... one lucky person from each sub this is posted on (Sporeswap, Sporetraders, and MillyWyco) will receive Milly's Mega Box for FREE! I just made this up...don't try to go looking for it to buy. What is Milly's Mega Box you ask? This variety pack includes 10 cubensis syringes, 5 exotic syringes, a book from Ram Dass or Terence McKenna (God I love these guys!), and some really cool stickers! That's 15 syringes, a book, and rad stickers for FREE, given away on each sub :) All you have to do is comment something good that has come of 2020 (I know you have something), and I'll have one lucky comment chosen at random for the winner on each sub. Extra points for comedy...we could all use it...but still just chosen at random. Mush Love <3
This week, I have restocked a few favorites, including Albino A+, Golden Mammoth, Golden Teacher, B+, PE6, PEU, Blue Meanie, Z-Strain, Koh Samui Super Strain, Costa Rican, Mazatapec, PES Amazon, Jedi Mind Fuck, McKennaii, Huautla, Thai Lipa Yai and a few others!

These are NOT cubensis, and NOT recommended for beginners. USE COUPON CODE "NEEDMORE" on the site to add ONE EXOTIC on to a 5 pack. Want 2 Exotics? Use code NEEDMORE2 or NEEDMORE3 for 3, etc. Currently this is setup to add a maximum of 5 exotics....if you need more, please message me and I'll create a unique coupon code to enter for your order :)

All syringes are 12cc/mL and come capped with a sterile tip cap, and also include an 18ga BD sterile needle and alcohol pads. Syringes are made in a lab grade environment and the utmost care and attention is the highest priority to be sure they are sterile. Anything exposed to an open air environment is subject to contamination, but I take every precaution possible to minimize this risk. I cannot "guarantee" they are 100% sterile, but I can guarantee that if you have an issue, I will make it right. I really do love to help, and if something happens, I'd like to know about it so I can fix the issue instead of you getting frustrated or giving up!
To ensure equal quantity of spores in each syringe, and for adequate suspension of the spores in the solution, I use a magnetic stir plate. Very often, this does such a good job of breaking up clumps of spores that it will appear to be sparse. THIS IS NOT AN ISSUE! There are still a TON of spores in each syringe, even if you can't see them individually (though most of my syringes appear to have a very good amount of visible spores...even with my horrible eyesight!). You can compare and contrast to see the blackish/purple tint to ensure every syringe is packed with spores. If a spore clump forms during transportation, simply give it a good flick with your finger and vigorously shake to break it up or free it from clinging to the wall of the syringe before examining.
Syringes ship in individual bags clearly labeled as to specific variety and born on date, bubble wrapped and shipped through USPS tracked shipping (discreet) within 24 hours of payment. I send tracking info soon after payment and give updates along the (super quick) way.
Any messages referring to spores being used for anything other than microscopy use will be ignored. Don't do it.
THANK YOU ALL so much again for your continued support!! I appreciate it more than you know! MUSH LOVE
P.S. In no way am I trying to be an impostor. I AM NOT WILLY MYCO. I chose this u/ a while back as sort of a play on words and tribute to a legend most of us recognize, long before I became a spore vendor. I don't want anyone to think I am trying to pass off as him, though I do strive for his level of excellence and dedication to the craft! I appreciate all of the kind words, though, from people saying they learned from "my" videos. I wish I could pass on those notes to RR himself.

Since they're calling for r/btc to be banned...

Maybe it's time to discuss bitcoin's history again. Credit to u/singularity87 for the original post over 3 years ago.

People should get the full story of bitcoin because it is probably one of the strangest of all reddit subs.
bitcoin, the main sub for the bitcoin community is held and run by a person who goes by the pseudonym u/theymos. Theymos not only controls bitcoin, but also bitcoin.org and bitcointalk.com. These are top three communication channels for the bitcoin community, all controlled by just one person.
For most of bitcoin's history this did not create a problem (at least not an obvious one anyway) until around mid 2015. This happened to be around the time a new player appeared on the scene, a for-profit company called Blockstream. Blockstream was made up of/hired many (but not all) of the main bitcoin developers. (To be clear, Blockstream was founded before mid 2015 but did not become publicly active until then). A lot of people, including myself, tried to point out there we're some very serious potential conflicts of interest that could arise when one single company controls most of the main developers for the biggest decentralised and distributed cryptocurrency. There were a lot of unknowns but people seemed to give them the benefit of the doubt because they were apparently about to release some new software called "sidechains" that could offer some benefits to the network.
Not long after Blockstream came on the scene the issue of bitcoin's scalability once again came to forefront of the community. This issue came within the community a number of times since bitcoins inception. Bitcoin, as dictated in the code, cannot handle any more than around 3 transactions per second at the moment. To put that in perspective Paypal handles around 15 transactions per second on average and VISA handles something like 2000 transactions per second. The discussion in the community has been around how best to allow bitcoin to scale to allow a higher number of transactions in a given amount of time. I suggest that if anyone is interested in learning more about this problem from a technical angle, they go to btc and do a search. It's a complex issue but for many who have followed bitcoin for many years, the possible solutions seem relatively obvious. Essentially, currently the limit is put in place in just a few lines of code. This was not originally present when bitcoin was first released. It was in fact put in place afterwards as a measure to stop a bloating attack on the network. Because all bitcoin transactions have to be stored forever on the bitcoin network, someone could theoretically simply transmit a large number of transactions which would have to be stored by the entire network forever. When bitcoin was released, transactions were actually for free as the only people running the network were enthusiasts. In fact a single bitcoin did not even have any specific value so it would be impossible set a fee value. This meant that a malicious person could make the size of the bitcoin ledger grow very rapidly without much/any cost which would stop people from wanting to join the network due to the resource requirements needed to store it, which at the time would have been for very little gain.
Towards the end of the summer last year, this bitcoin scaling debate surfaced again as it was becoming clear that the transaction limit for bitcoin was semi regularly being reached and that it would not be long until it would be regularly hit and the network would become congested. This was a very serious issue for a currency. Bitcoin had made progress over the years to the point of retailers starting to offer it as a payment option. Bitcoin companies like, Microsoft, Paypal, Steam and many more had began to adopt it. If the transaction limit would be constantly maxed out, the network would become unreliable and slow for users. Users and businesses would not be able to make a reliable estimate when their transaction would be confirmed by the network.
Users, developers and businesses (which at the time was pretty much the only real bitcoin subreddit) started to discuss how we should solve the problem bitcoin. There was significant support from the users and businesses behind a simple solution put forward by the developer Gavin Andreesen. Gavin was the lead developer after Satoshi Nakamoto left bitcoin and he left it in his hands. Gavin initially proposed a very simple solution of increasing the limit which was to change the few lines of code to increase the maximum number of transactions that are allowed. For most of bitcoin's history the transaction limit had been set far far higher than the number of transactions that could potentially happen on the network. The concept of increasing the limit one time was based on the fact that history had proven that no issue had been cause by this in the past.
A certain group of bitcoin developers decided that increasing the limit by this amount was too much and that it was dangerous. They said that the increased use of resources that the network would use would create centralisation pressures which could destroy the network. The theory was that a miner of the network with more resources could publish many more transactions than a competing small miner could handle and therefore the network would tend towards few large miners rather than many small miners. The group of developers who supported this theory were all developers who worked for the company Blockstream. The argument from people in support of increasing the transaction capacity by this amount was that there are always inherent centralisation pressure with bitcoin mining. For example miners who can access the cheapest electricity will tend to succeed and that bigger miners will be able to find this cheaper electricity easier. Miners who have access to the most efficient computer chips will tend to succeed and that larger miners are more likely to be able to afford the development of them. The argument from Gavin and other who supported increasing the transaction capacity by this method are essentially there are economies of scale in mining and that these economies have far bigger centralisation pressures than increased resource cost for a larger number of transactions (up to the new limit proposed). For example, at the time the total size of the blockchain was around 50GB. Even for the cost of a 500GB SSD is only $150 and would last a number of years. This is in-comparison to the $100,000's in revenue per day a miner would be making.
Various developers put forth various other proposals, including Gavin Andresen who put forth a more conservative increase that would then continue to increase over time inline with technological improvements. Some of the employees of blockstream also put forth some proposals, but all were so conservative, it would take bitcoin many decades before it could reach a scale of VISA. Even though there was significant support from the community behind Gavin's simple proposal of increasing the limit it was becoming clear certain members of the bitcoin community who were part of Blockstream were starting to become increasingly vitriolic and divisive. Gavin then teamed up with one of the other main bitcoin developers Mike Hearn and released a coded (i.e. working) version of the bitcoin software that would only activate if it was supported by a significant majority of the network. What happened next was where things really started to get weird.
After this free and open source software was released, Theymos, the person who controls all the main communication channels for the bitcoin community implemented a new moderation policy that disallowed any discussion of this new software. Specifically, if people were to discuss this software, their comments would be deleted and ultimately they would be banned temporarily or permanently. This caused chaos within the community as there was very clear support for this software at the time and it seemed our best hope for finally solving the problem and moving on. Instead a censorship campaign was started. At first it 'all' they were doing was banning and removing discussions but after a while it turned into actively manipulating the discussion. For example, if a thread was created where there was positive sentiment for increasing the transaction capacity or being negative about the moderation policies or negative about the actions of certain bitcoin developers, the mods of bitcoin would selectively change the sorting order of threads to 'controversial' so that the most support opinions would be sorted to the bottom of the thread and the most vitriolic would be sorted to the top of the thread. This was initially very transparent as it was possible to see that the most downvoted comments were at the top and some of the most upvoted were at the bottom. So they then implemented hiding the voting scores next to the users name. This made impossible to work out the sentiment of the community and when combined with selectively setting the sorting order to controversial it was possible control what information users were seeing. Also, due to the very very large number of removed comments and users it was becoming obvious the scale of censorship going on. To hide this they implemented code in their CSS for the sub that completely hid comments that they had removed so that the censorship itself was hidden. Anyone in support of scaling bitcoin were removed from the main communication channels. Theymos even proudly announced that he didn't care if he had to remove 90% of the users. He also later acknowledged that he knew he had the ability to block support of this software using the control he had over the communication channels.
While this was all going on, Blockstream and it's employees started lobbying the community by paying for conferences about scaling bitcoin, but with the very very strange rule that no decisions could be made and no complete solutions could be proposed. These conferences were likely strategically (and successfully) created to stunt support for the scaling software Gavin and Mike had released by forcing the community to take a "lets wait and see what comes from the conferences" kind of approach. Since no final solutions were allowed at these conferences, they only served to hinder and splinter the communities efforts to find a solution. As the software Gavin and Mike released called BitcoinXT gained support it started to be attacked. Users of the software were attack by DDOS. Employees of Blockstream were recommending attacks against the software, such as faking support for it, to only then drop support at the last moment to put the network in disarray. Blockstream employees were also publicly talking about suing Gavin and Mike from various different angles simply for releasing this open source software that no one was forced to run. In the end Mike Hearn decided to leave due to the way many members of the bitcoin community had treated him. This was due to the massive disinformation campaign against him on bitcoin. One of the many tactics that are used against anyone who does not support Blockstream and the bitcoin developers who work for them is that you will be targeted in a smear campaign. This has happened to a number of individuals and companies who showed support for scaling bitcoin. Theymos has threatened companies that he will ban any discussion of them on the communication channels he controls (i.e. all the main ones) for simply running software that he disagrees with (i.e. any software that scales bitcoin).
As time passed, more and more proposals were offered, all against the backdrop of ever increasing censorship in the main bitcoin communication channels. It finally come down the smallest and most conservative solution. This solution was much smaller than even the employees of Blockstream had proposed months earlier. As usual there was enormous attacks from all sides and the most vocal opponents were the employees of Blockstream. These attacks still are ongoing today. As this software started to gain support, Blockstream organised more meetings, especially with the biggest bitcoin miners and made a pact with them. They promised that they would release code that would offer an on-chain scaling solution hardfork within about 4 months, but if the miners wanted this they would have to commit to running their software and only their software. The miners agreed and the ended up not running the most conservative proposal possible. This was in February last year. There is no hardfork proposal in sight from the people who agreed to this pact and bitcoin is still stuck with the exact same transaction limit it has had since the limit was put in place about 6 years ago. Gavin has also been publicly smeared by the developers at Blockstream and a plot was made against him to have him removed from the development team. Gavin has now been, for all intents an purposes, expelled from bitcoin development. This has meant that all control of bitcoin development is in the hands of the developers working at Blockstream.
There is a new proposal that offers a market based approach to scaling bitcoin. This essentially lets the market decide. Of course, as usual there has been attacks against it, and verbal attacks from the employees of Blockstream. This has the biggest chance of gaining wide support and solving the problem for good.
To give you an idea of Blockstream; It has hired most of the main and active bitcoin developers and is now synonymous with the "Core" bitcoin development team. They AFAIK no products at all. They have received around $75m in funding. Every single thing they do is supported by theymos. They have started implementing an entirely new economic system for bitcoin against the will of it's users and have blocked any and all attempts to scaling the network in line with the original vision.
Although this comment is ridiculously long, it really only covers the tip of the iceberg. You could write a book on the last two years of bitcoin. The things that have been going on have been mind blowing. One last thing that I think is worth talking about is the u/bashco's claim of vote manipulation.
The users that the video talks about have very very large numbers of downvotes mostly due to them having a very very high chance of being astroturfers. Around about the same time last year when Blockstream came active on the scene every single bitcoin troll disappeared, and I mean literally every single one. In the years before that there were a large number of active anti-bitcoin trolls. They even have an active sub buttcoin. Up until last year you could go down to the bottom of pretty much any thread in bitcoin and see many of the usual trolls who were heavily downvoted for saying something along the lines of "bitcoin is shit", "You guys and your tulips" etc. But suddenly last year they all disappeared. Instead a new type of bitcoin user appeared. Someone who said they were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did. They had the exact same tone as the trolls who had disappeared. Their way to talking to people was aggressive, they'd call people names, they had a relatively poor understanding of how bitcoin fundamentally worked. They were extremely argumentative. These users are the majority of the list of that video. When the 10's of thousands of users were censored and expelled from bitcoin they ended up congregating in btc. The strange thing was that the users listed in that video also moved over to btc and spend all day everyday posting troll-like comments and misinformation. Naturally they get heavily downvoted by the real users in btc. They spend their time constantly causing as much drama as possible. At every opportunity they scream about "censorship" in btc while they are happy about the censorship in bitcoin. These people are astroturfers. What someone somewhere worked out, is that all you have to do to take down a community is say that you are on their side. It is an astoundingly effective form of psychological attack.

[ Bitcoin ] Technical: Taproot: Why Activate?

Topic originally posted in Bitcoin by almkglor [link]
This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given private key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Summary

I Wanna Be The Taprooter!

So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!

But I Hate Taproot!!

That's fine!

My dearest friends, mush lovers and fellow mycologists, welcome back to another edition of Wyco Wednesday! I took some time off last week for my anniversary, got caught up on some mush needed organization, and got ahead on restocking some of the more popular varieties, while adding 5 new ones to the library! Thank you so much to everyone who wished us a happy anniversary and were patient during an off week! And to everyone who added a note on your last order about something positive in your life...it truly warmed my heart. I know it's easy to focus on all the surprises 2020 has gifted us so far, but it really put a smile on my face to see the highlights of what good has happened in everyone's life recently. Keep that positivity flowing! Also, if anyone added a note in the "feedback" section, instead of the "notes" with the transaction, unfortunately I was not getting those messages. If you were expecting a freebie with your happy note but were left out due to the feedback vs. note issue, please let me know and I'll have something on the way to you STAT!
In other news...gourmets are....still coming. Unfortunately, that's all I have for you guys at the moment, as some personal issues are delaying the process just a bit. A couple of weeks ago, I promised I would have a concrete date for when these gourmet liquid cultures will roll out, and I'm sorry I was not able to see that promise through. My gourmet grower had some unexpected life stuffs thrown his way, and needs to take care of some things for his family before resuming the process. I, as well as most of you in the community, recognize the importance of mental health and work/life balance as a priority over any work or hobby related activities. We appreciate your patience, and will have an update as soon as humanly possible! No matter how many curve balls 2020 tries to throw, we will come out of this better and stronger than ever! GOOD WILL PREVAIL.
To ensure quality specimens and packaging, and due to the onslaught of orders on Wednesday's, all orders placed on Wednesday's will be shipped on Thursday and Friday of that week. You will receive an email notification with a tracking link when your order ships. I appreciate your patience so hard!
The first 10 orders placed after this post (Order #12673-12682) will receive a FREE (very small) mushroom hand painted canvas! As with any of the artsy fartsy crafty thingies, DO NOT have high hopes for these items. I'm trying out something new each week to work on my own work/life balance struggles, and want to share some of my creations with you. Unfortunately, I am not such a creative person, and it shows. Throw it away, laugh, do what you wish with them, but know that when I'm making them, I'm in a meditative mindset, thinking about how all of you have blessed me and allowed me to continue living my dream. I hope this gives some of you a smile or mush needed pick-me-up on a rough day, and I encourage you to pay it forward, and make someone else's day too. We're all in this together :)
P.S. This week's craft was chosen based on a poll I posted on the MW sub. Next week will be the runner up: resin crafts! Check back on the sub soon for another poll, or comment with what you'd like to see coming up!
ALSO...in addition to the first 10 promo, and going with tradition the past couple months, any order number ending in 7, 1, or 5 on 7/15 will also get a FREE bonus unlisted syringe not available in the shop with their order!
FINALLY...and this is the big one... one lucky person from each sub this is posted on (Sporeswap, Sporetraders, and MillyWyco) will receive Milly's Mega Box for FREE! I just made this up...don't try to go looking for it to buy. What is Milly's Mega Box you ask? This variety pack includes 10 cubensis syringes, 5 exotic syringes, a book from Ram Dass or Terence McKenna (God I love these guys!), and some really cool stickers! That's 15 syringes, a book, and rad stickers for FREE, given away on each sub :) All you have to do is comment something good that has come of 2020 (I know you have something), and I'll have one lucky comment chosen at random for the winner on each sub. Extra points for comedy...we could all use it...but still just chosen at random. Mush Love <3
This week, I have restocked a few favorites, including Albino A+, Golden Mammoth, Golden Teacher, B+, PE6, PEU, Blue Meanie, Z-Strain, Koh Samui Super Strain, Costa Rican, Mazatapec, PES Amazon, Jedi Mind Fuck, McKennaii, Huautla, Thai Lipa Yai and a few others!

All syringes are 12cc/mL and come capped with a sterile tip cap, and also include an 18ga BD sterile needle and alcohol pads. Syringes are made in a lab grade environment and the utmost care and attention is the highest priority to be sure they are sterile. Anything exposed to an open air environment is subject to contamination, but I take every precaution possible to minimize this risk. I cannot "guarantee" they are 100% sterile, but I can guarantee that if you have an issue, I will make it right. I really do love to help, and if something happens, I'd like to know about it so I can fix the issue instead of you getting frustrated or giving up!
To ensure equal quantity of spores in each syringe, and for adequate suspension of the spores in the solution, I use a magnetic stir plate. Very often, this does such a good job of breaking up clumps of spores that it will appear to be sparse. THIS IS NOT AN ISSUE! There are still a TON of spores in each syringe, even if you can't see them individually (though most of my syringes appear to have a very good amount of visible spores...even with my horrible eyesight!). You can compare and contrast to see the blackish/purple tint to ensure every syringe is packed with spores. If a spore clump forms during transportation, simply give it a good flick with your finger and vigorously shake to break it up or free it from clinging to the wall of the syringe before examining.
Syringes ship in individual bags clearly labeled as to specific variety and born on date, bubble wrapped and shipped through USPS tracked shipping (discreet) within 24 hours of payment. I send tracking info soon after payment and give updates along the (super quick) way.
Any messages referring to spores being used for anything other than microscopy use will be ignored. Don't do it.
THANK YOU ALL so much again for your continued support!! I appreciate it more than you know! MUSH LOVE
P.S. In no way am I trying to be an impostor. I AM NOT WILLY MYCO. I chose this u/ a while back as sort of a play on words and tribute to a legend most of us recognize, long before I became a spore vendor. I don't want anyone to think I am trying to pass off as him, though I do strive for his level of excellence and dedication to the craft! I appreciate all of the kind words, though, from people saying they learned from "my" videos. I wish I could pass on those notes to RR himself.
Cheers and MUSH LOVE!

My dear friends and sexy mycologists, how are we doing this fine JULY evening? I can't believe this year is already halfway over! Time flies when you're....in quarantine? At least it has for me with all of you keeping me busy, and I can't thank you enough for all of the support, appreciation, words of encouragement...and all those cat facts. Gotta love em.
Something that has often been brought to my attention recently (not mycology related...skip ahead if you just want to get down to business) has been positive and negative self talk. That little voice inside your head (for some louder than others) that's always interrupted when you have a new thought or distraction from an outside influence. This could very well be defined as your mood and overall well-being. If you let this little voice go, it will keep chatting you up as long as you let it. I know there are a lot of problems in the world right now that we can focus on and let that voice run wild with negative chatter, but that sets the tempo for your entire day! We all have our own personal struggles and daily battles that we have to face, but it can make a world of difference (and a difference in the world) if we focus on what's good in our lives and let that self talk sing praises instead of weighing you down. Be thankful each and every day just for being alive. Life alone is a miracle, and we take it for granted far too often. Appreciate the small things, be kind to everyone and every thing, and treat each day as a new beginning. If anyone is feeling down about anything that's going on in their life, no matter haw trivial or catastrophic, please reach out to me! Everyone needs a friend or someone to just listen to what's going on in their life, and I'd love to give back to a community who has helped me in so many ways. We're all in this together. We're all just walking each other home :)
Adding to this note on positivity...anyone who places an order on the site and adds a note at checkout telling me something positive that has happened in your life recently will get a bonus syringe on me :) You can choose to use the freebie for yourself, or better yet, find a friend who could use a little mentoring or someone who could use a new hobby, and gift it to them to pay it forward. We all know someone with even just a twinkle of curiosity about mycology or plant medicines, and I know if someone just handed me a large component of getting started, it would be off to the races with research. Let's grow this community!
Down to business...
Next week I will not have a Wyco Wednesday inventory update. The varieties and stock that are shown in the shop today is what's available while they last, and will not be restocked when they run out until the Wyco Wednesday update on 7/15. 7/8 is my anniversary and I'd like to take some time for my relationship without having non-stop work the days leading up to and following that day. I will still be shipping all orders within 24 hours of being placed as usual, just no new inventory. BUT! That means the Wyco Wednesday on 7/15 will be rather glorious, with at least 5 new cubensis varieties! YEET!
GOURMETS. ARE. COMING!!
This has been a work in progress for a good while, and I am soooo incredibly excited for this new line of products! The first to roll out will be Lion's Mane and Turkey Tail, with many more to follow! I plan to roll out a couple of new gourmet's every couple of weeks to ensure the absolute highest quality liquid cultures. Myco Box subscriptions will be able to mix-and-match cubensis as well as gourmet's when they are ready, and pricing will match the usual for cubensis as well. More details will follow, and I'll write a little ditty on my sub here shortly so I don't clutter up these pristine subs. Show yo mods some appreciation! They're working hella hard to make sure we stay up and running here. They deserve ALLLLL the cookies.
To ensure quality specimens and packaging, and due to the onslaught of orders on Wednesday's, all orders placed on Wednesday's will be shipped on Thursday and Friday of that week. You will receive an email notification with a tracking link when your order ships. I appreciate your patience so hard!
The first 15 orders placed after this post (Order #12383-12397) will receive a FREE mushroom artsy fartsy crafty thingy! It's a surprise, but something to show my appreciation for you early birds :) I started this promo last week, where I made a handful of "Mush Love" kandi bracelets, and I plan on continuing this promo regularly on Wyco Wednesdays with a new craft each week (trying to tap into my creative side). This week will be a mystery as well, but pic of some of the handouts can be found on the MW subreddit later on this evening after the first 15 orders are placed :)
ALSO...in addition to the first 15 promo, and going with tradition the past couple months, any order number ending in 7, 0, or 1 on 7/01 will also get a FREE unlisted syringe not available in the shop with their order!
This week, I have restocked a few favorites, including Albino A+, Golden Mammoth, Golden Teacher, B+, PE6, PEU, Blue Meanie, Z-Strain, Cambodian Gold, Creeper, Ecuadorian, Fiji, Jedi Mind Fuck, McKennaii, Taman Negara, Rusty Whyte, Mazatapec, Orissa India and a few others! New additions this week include Daddy Long Legs, S. African Transkei, Ps. Cyanescens (Wavy Caps), ORIGINAL Penis Envy and Mexicana Galindoi!
Thank you so much to everyone who has subscribed to a subscription box! Each and every month, these boxes will get better and better :) Newsletters will go out on the first of each month, regardless of when your plan is set to renew. In these newsletters will also be the winner of the random equipment raffle for MASTER PLAN members! This could be a sterilization wand, dehydrator, magnetic stir plate, or other super duper helpful tools in the hobby.
