Config for regtest

[sipsorcery]

With the now deprecated liquidd I can use regtest with the configurations below. My bitcoin core version is 0.18.0.

bitcoin.conf

regtest=1
server=1
daemon=0
datadir=m:\blockchains\bitcoin
debug=rpc

liquid.conf

regtest=1
server=1
daemon=0
validatepegin=1
datadir=m:\blockchains\liquid
mainchainrpchost=127.0.0.1
mainchainrpcport=18443
mainchainrpccookiefile=m:\blockchains\bitcoin\regtest\.cookie

I am unable to do the same thing with elementsd using:

elements.conf

regtest=1
server=1
daemon=0
validatepegin=1
datadir=m:\blockchains\liquid
mainchainrpchost=127.0.0.1
mainchainrpcport=18443
mainchainrpccookiefile=m:\blockchains\bitcoin\regtest\.cookie

[regtest]
rpcport=19884

The error message is:

2019-08-06T09:48:36Z ERROR: Invalid parent genesis block hash response via RPC. Contacting wrong parent daemon?
2019-08-06T09:48:36Z Error: ERROR: elementsd is set to verify pegins but cannot get valid response from the mainchain daemon. Please check debug.log for more information.

If you haven't setup a bitcoind please get the latest stable version from https://bitcoincore.org/en/download/ or if you do not need to validate pegins set in your elements configuration validatepegin=0

The elementsd daemon is able to successfully connect to my bitcoind daemon. These messages appear in the bitcoind logs when elementd starts:

Finally found it in https://docs.blockstream.com/liquid/node_setup.html.

In elements.conf use:
chain=elementsregtest
