BDK rpc cli setup and testing

Some notes on my manual rpc cli setup and testing:

  1. start bitcoind in regtest mode
mkdir /tmp/bitcoind
bitcoind -datadir=/tmp/bitcoind -regtest -server -fallbackfee=0.0002 -rpcallowip=0.0.0.0/0 -rpcbind=0.0.0.0 -blockfilterindex=1 --peerblockfilters=1 -daemon
  1. create bitcoind test wallet and generate blocks
bitcoin-cli -datadir=/tmp/bitcoind -regtest createwallet "test"

Privacy preserving multi-sig signing service

Privacy preserving multi-sig signing service

Problem

Create a signing service that when properly authorized will add valid signatures to a client's PSBT without knowing the client's full wallet history. The signing service must be able to determine the transaction spending amount. The client must be able to sign and finalize a transactions independently of the service.

Solution

  1. For each client the signing service creates a signing bip39 xprv key and shares the corresponding xpub with the client's software. The signing service does not need to share any root key information with the client except the key fingerprint. Example:
