## Mining
Support only remote-miners.
2021-09-07 08:57:31 +00:00
* To enable, add `--mine --miner.etherbase=...` or `--mine --miner.sigfile=...` flags.
2021-03-30 09:18:57 +00:00
* 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](/eth/stagedsync/)
* 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
2021-03-30 09:18:57 +00:00
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:
2021-05-26 10:35:39 +00:00
+ we don't broadcast mined blocks to p2p-network yet, [but it's easy to accomplish ](https://github.com/ledgerwatch/erigon/blob/9b8cdc0f2289a7cef78218a15043de5bdff4465e/eth/downloader/downloader.go#L673 )
