The default bitcoind settings, having more than one instance of lnd, or Don’t connect more than two or three instances of lnd to bitcoind.Messages like this as lnd consumes blocks from bitcoind. Normal lnd output will quickly show multiple Sync, start_height=XXXXXX” as the last entry in the console or log output, and Is experiencing this issue, you’ll see “Waiting for chain backend to finish Slow inter-process-communication between lnd and the bitcoind backend. If you use “localhost” as the host name, you may see extremely When running lnd and bitcoind on the same Windows machine, ensure you useġ27.0.0.1, not localhost, for all configuration options that require a TCP/IP.You must ensure the same addresses are used for the bitcoind.zmqpubrawblockĪnd bitcoind.zmqpubrawtx options passed to lnd as for the zmqpubrawblockĪnd zmqpubrawtx passed in the bitcoind options respectively.Will attempt to get the configuration from your nf. Shown in example command above), you must also specify theīitcoind.zmqpubrawblock and bitcoind.zmqpubrawtx options. If you DO choose to explicitly pass the auth parameters in your lnd.conf orĬommand line options for lnd ( bitcoind.rpcuser and bitcoind.rpcpass as.In this case, you can exclude them from the The auth parameters rpcuser and rpcpass parameters can typically beĭetermined by lnd for a bitcoind instance running under the same user,.Lnd -bitcoin.active -bitcoin.testnet -debuglevel=debug -bitcoin.node=bitcoind -bitcoind.rpcuser=REPLACEME -bitcoind.rpcpass=REPLACEME -bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332 -bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333 -externalip=X.X.X.X The testnet chain (alternatively, use -bitcoind.regtest instead). Start bitcoind running against testnet, and let it complete a full sync with.To provide a reliable delivery of notifications (e.g. These options must each use their own unique address in order Configure the bitcoind instance for ZMQ with -zmqpubrawblock and.In the latest Homebrew recipe for bitcoin) If you installed bitcoind via Homebrew in the past ZMQ may not be included Then ZMQ support will be disabled, and lnd will quit on a connection refused error. Note that if you installed bitcoind from source and ZMQ was not present, Interface with bitcoind, your bitcoind installation must be compiled with To configure your bitcoind backend for use with lnd, first complete and verify Generally operate faster as it can hit the index directly, rather than scanningīlocks or BIP 158 filters for relevant items. Optional, as it will take longer to sync the node, but then lnd will Uses a distinct litecoin.node=litecoind argument and analogous Setup will be described in regards to bitcoind, but note that lnd The configuration for bitcoind and litecoind are nearly identical, theįollowing steps can be mirrored with loss of generality to enable a litecoindīackend.
