SmartPool: Practical Decentralized Pooled Mining
summary
SMARTPOOL is a deployed decentralized mining-pool protocol running on Ethereum and Ethereum Classic that pays miners with a probabilistic sampling scheme and forces batch-commitments so on-chain verification stays cheap. Batches commit a root; the contract samples paths and catches mis-sorting via an Augmented Merkle tree witness. Implementation mines live (86 blocks in June–July 2017, ≈$2,200/day), runs at a 0.6% fee, and uses ~2.6M gas per submission under the 6.7M block gas limit.
