Proof of work code in python

WebProof-of-work is the underlying algorithm that sets the difficulty and rules for the work miners do on proof-of-work blockchains. Mining is the "work" itself. It's the act of adding valid blocks to the chain. This is important because the chain's length helps the network follow the correct fork of the blockchain. WebVerifier has two Bloom filters: current and previous, and operates using following algorithm: Check that timestamp is within validity range: Math.abs (timestamp - Date.now ()) <= …
