Shaicoin is designed to bring back the essence of decentralized mining that Satoshi envisioned. Shaicoin is a Bitcoin fork that leverages the ShaiHive mining algorithm, which reintroduces the original CPU mining code from Bitcoin Core v0.12.0, modified and upgraded.
ShaiHive introduces a Hamiltonian graph certificate in the block header, which serves as a "nonce selection speed bump," aiming to maintain the integrity and fairness of the mining process
