Returns a net.Server
that accepts ABCI connections from a Tendermint node.
app
should be an object with ABCI method handler functions. Each handler receives one request
argument, and can return the response value or a Promise
which resolves to the response value. cb
responds to the ABCI request with either the error or response
value.
Supported ABCI methods are:
echo
flush
info
setOption
initChain
query
beginBlock
checkTx
deliverTx
endBlock
