TxPool v2
Design docs: https://github.com/ledgerwatch/erigon/wiki/Transaction-Pool-Design
Has 2 modes: internal and external
Internal mode
Works inside Erigon: add --txpool.v2 flags to Erigon, and --txpool.v2 --txpool.api.addr localhost:9090 flags to
RPCDaemon
External mode
Works in separated process and require external Sentry. TxPool connect to Erigon and Sentry. RPCDaemon connect to TxPool. Build by:
make txpool
Start by:
# Add `--state.stream --txpool.disable` flags to Erigon.
./build/bin/sentry
./build/bin/txpool
To change address/port of Erigon or Sentry:
./build/bin/txpool --private.api.addr localhost:9090 --sentry.api.addr localhost:9091 --txpool.api.addr localhost:9094
Increase pool limits
Will add this part soon [tbd]
ToDo list
[x] Remote-mode support - with coherent state cache [x] Persistence [x] Grafana board [x] Non-mainnet support [x] DevNet - doesn't send mined block notification on first mined block (because initialCycle = true) [x] DiscardReasons - user must understand clearly why tx were rejected [x] Notify about new pending transactions - we sending more than need [x] Handle "NewBlock" message with 200K transactions re-calculation - in under 50ms [x] Add --txpool.globalslots, --txpool.globalqueue,--txpool.globalbasefeeeslots [] Add --txpool.accountslots [] Add --txpool.pricelimit [] Add way for simple introspection - where is tx and why [] Hard-forks support (now rules are parsed ones on txPool start) [] Add pool to docker-compose [] Add pool (db table) - where store recently mined txs - for faster unwind/reorg. [] Save history of local transactions - with 1 day expiration
