Shaicoin

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 to v0.27.0.

What Makes Shaicoin Unique?
Shaicoin 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. The Bitcoin block header has been expanded from 80 bytes to 4096 bytes to accommodate this certificate, allowing for quick verification of the graph cycle.

- Kismets are equivalent to Satoshis
- SHA is equivalent to BTC

Block Rewards and Supply
- Initial block reward: 11 SHA
- Block reward decreases by 1226 kismets every block (tail emission kicks in at block 888420 of 0.1 SHA per block)
- Block time: 2 minutes
- Difficulty: Adjusted every block if necessary

The initial blockchain launch encountered an issue where the hash space was too small, leading to hash collisions and node desynchronization. This problem has since been resolved by restoring the hashing space to the full block instead of just the verifiable delay function space (graph certificate). As a result, when the network was relaunched, it was necessary to consolidate the rewards from the previous chain to ensure fair repayment to early miners. Consequently, Block 1 contains 420,690 SHA, which includes both the community incentive wallet and the obligations owed to early miners from the initial network. Detailed information about the usage of this wallet will be provided in the Discord.

Total Supply
The total supply of Shaicoin over the next 4 years will be approximately 5.5 million SHA. At Block 888,420, a tail emission will begin, introducing a steady issuance rate of 0.1 SHA per block.

Join the Shaicoin Network
To start mining Shaicoin, you'll need to download and compile the code. The source code is available on GitHub: Shaicoin GitHub Repository.

- Default P2P port: 42069
- Default RPC port: 8710

For macOS users, follow this mining instructions guide. Ubuntu and Windows users can compile the Shaicoin node similarly to Bitcoin, using the "-moneyplz" flag once the wallet is created.
