Mempool Messages

P2P Messages

There is currently only one message that Mempool broadcasts and receives over the p2p gossip network (via the reactor): TxMessage

// TxMessage is a MempoolMessage containing a transaction.
type TxMessage struct {
    Tx types.Tx
}

TxMessage is go-wire encoded and prepended with 0x1 as a "type byte". This is followed by a go-wire encoded byte-slice. Prefix of 40=0x28 byte tx is: 0x010128... followed by the actual 40-byte tx. Prefix of 350=0x015e byte tx is: 0x0102015e... followed by the actual 350 byte tx.

(Please see the go-wire repo for more information)

RPC Messages

Mempool exposes CheckTx([]byte) over the RPC interface.

It can be posted via broadcast_commit, broadcast_sync or broadcast_async. They all parse a message with one argument, "tx": "HEX_ENCODED_BINARY" and differ in only how long they wait before returning (sync makes sure CheckTx passes, commit makes sure it was included in a signed block).

Request (POST http://gaia.zone:26657/):

  "id": "",
  "jsonrpc": "2.0",
  "method": "broadcast_sync",
