Mining

Support only remote-miners.

  • To enable, add --mine --miner.etherbase=... or --mine --miner.sigfile=... flags.
  • Other supported options: --miner.extradata, --miner.notify, --miner.gaslimit, --miner.gasprice , --miner.gastarget
  • RPCDaemon supports methods: eth_coinbase , eth_hashrate, eth_mining, eth_getWork, eth_submitWork, eth_submitHashrate
  • RPCDaemon supports websocket methods: newPendingTransaction

Implementation details

  • mining implemented as independent 🔬Staged Sync
  • stages are declared in eth/stagedsync/stagebuilder.go:MiningStages
  • mining work done inside 1 db transaction which RollingBack after block prepared and --miner.notify notifications sent

Testing

Integration tool - supports mining of existing blocks. It moves Erigon to block X, does mine block X+1, then compare mined block with real block X+1 in db. To enable - just add --mine --miner.etherbase=<etherbase> flag to integration state_stages command:

./build/bin/integration state_stages --datadir=<datadir> --unwind=1 --unwind.every=2 --integrity.fast=false --integrity.slow=false --mine --miner.etherbase=<etherbase>
  • TODO:
    • we don't broadcast mined blocks to p2p-network yet, but it's easy to accomplish
    • eth_newPendingTransactionFilter
    • eth_newBlockFilter
    • eth_newFilter
    • websocket Logs
