About Shardhash

Shardhash is an autonomous proof-of-work protocol deployed on Ethereum.<br>Every Ethereum block begins a new mining round, allowing anyone to search<br>for valid cryptographic solutions using standard CPUs or GPUs.

Mining challenges are derived deterministically from recent Ethereum block<br>hashes, requiring no external randomness, trusted coordinator, or off-chain<br>infrastructure. Every valid claim is verified entirely on-chain before new<br>SHARDEN tokens are minted directly to the successful miner.

Mining is completely stateless and parallel. Miners repeatedly hash a<br>challenge, round number, wallet address, and nonce in search of increasingly<br>rare solutions. Solution quality is measured by the number of consecutive<br>matching hexadecimal digits from the least significant end of the hash.

Higher-quality solutions become exponentially more difficult to discover<br>while earning exponentially larger rewards. Each reward tier can be claimed<br>only once per mining round, making speed of submission as important as<br>discovering high-quality solutions.
