TxPool v2

it’s exactly what you run inside Erigon now, but you also can disable pool inside erigon by —txpool.disable and run it outside ( so can run multiple of them, or use your own implementation, or customize logic).

Same thing you can do with sentry. Also, after the-megre you will run external consensus service.

95% of pool-related code (from p2p message parsing, to sorting logic) is inside this folder: https://github.com/ledgerwatch/erigon-lib/tree/main/txpool

Our pool implementation is not fork of Geth’s ( And it’s Apache licensed) - Design docs: https://github.com/ledgerwatch/erigon/wiki/Transaction-Pool-Design

Has 2 modes: internal and external

Internal mode

It's default. No special flags required. But if in RPCDaemon you using custom --private.api.addr flag, then set same value to --txpool.api.addr flag.

External mode

Add --txpool.disable to erigon. External TxPool 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 `--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

In ./build/bin/txpool --help see flags: --txpool.globalslots, --txpool.globalbasefeeeslots, --txpool.globalqueue

ToDo list

[] Hard-forks support (now TxPool require restart - after hard-fork happens) [] 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 [] move tx.rlp field to separated map, to make tx immutable
