All public keys or redeem script/witness script is required to signal the transaction when spending bitcoin multisig UTXO.
An experiment to see if you happen to can signal the transaction with out public keys:
-
Run
bitcoind -signet=1 -rpcport=38332 -rpcuser=consumer -rpcpassword=password
-
Create 3 wallets m1, m2 and m3
$ bitcoin-cli -named createwallet wallet_name=m1 descriptors=false
-
Get 3 public keys from every pockets:
$ bitcoin-cli -rpcwallet=m1 getnewaddress tb1q8hz93lwkmzjq2yapxr6mnsfwjt5wvp2f5zgm98 $ bitcoin-cli -rpcwallet=m1 getaddressinfo tb1q8hz93lwkmzjq2yapxr6mnsfwjt5wvp2f5zgm98 { "deal with": "tb1q8hz93lwkmzjq2yapxr6mnsfwjt5wvp2f5zgm98", "scriptPubKey": "00143dc458fdd6d8a40513a130f5b9c12e92e8e60549", "ismine": true, "solvable": true, "desc": "wpkh([045471ed/0'/0'/1']039927842080cc4a22d2d4a63c13b3d9a66564e230775981f03976787afe6cf716)#wht4f5zk", "iswatchonly": false, "isscript": false, "iswitness": true, "witness_version": 0, "witness_program": "3dc458fdd6d8a40513a130f5b9c12e92e8e60549", "pubkey": "039927842080cc4a22d2d4a63c13b3d9a66564e230775981f03976787afe6cf716", "ischange": false, "timestamp": 1663309171, "hdkeypath": "m/0'/0'/1'", "hdseedid": "ccd54fe6a42efde5251f8443f1edd7ebcf25fefa", "hdmasterfingerprint": "045471ed", "labels": [ "" ] }
