Mining Pool
A service that coordinates proof-of-work from many hashers and distributes rewards under a payout scheme.
A mining pool divides candidate work among participants and estimates each participant's contribution through lower-difficulty shares. When the pool finds an accepted block, it pays miners according to its payout rules.
In a conventional pool, the operator chooses the block template and transaction policy while individual miners supply hash power. Stratum variants and solo or decentralized pool designs can distribute those responsibilities differently.
Pool concentration can increase censorship, reorganization, and coordination risk even when the underlying hardware belongs to many operators. Miners also face counterparty, payout, fee, downtime, and share-withholding risk.
