Bitcoin mining is often thought of as the way to create new bitcoins. But that's really just a secondary purpose. The primary importance of mining is to ensure that all participants have a consistent view of the Bitcoin data. Because Bitcoin is a distributed peer-to-peer system, there is no central database that keeps track of who owns bitcoins. Nonce is a 32 bit arbitrary random number that is typically used once. In Bitcoin's mining process, the goal is to find a hash below a target number which is calculated based on the difficulty. Proof of work in Bitcoin's mining takes an input consists of Merkle Root, timestamp, previous block hash and few other things plus a nonce which is completely random number. Bitcoin stores the nonce in the extraNonce field which is part of the coinbase transaction, which is stored as the left most leaf node in the merkle tree (the coinbase is the special first transaction in the block). The counter parameter is small at 32-bits so each time it wraps the extraNonce field must be incremented (or otherwise changed) to A nonce for a block fits the definition well: it's rare for the same nonce to be valid in other blocks. A crytopgraphic nonce is a technique to prevent replay attacks, and matches the purpose of the account nonce. Replay attacks across blockchain forks, however, have shown that the account nonce isn't enough to prevent replays across forks. The nonce attribute enables you to “whitelist” certain inline script and style elements, while avoiding use of the CSP unsafe-inline directive (which would allow all inline script/style), so that you still retain the key CSP feature of disallowing inline script/style in general.. So the nonce attribute is way of telling browsers that the inline contents of a particular script or style
