I don't know if there is an error in the
scriptsig generation method of input in P2PSH.
My address is a single signing address with one Private key， I created a transaction that will generate hex string via Bitcoinj.
script = ScriptBuilder.createOutputScript(key.getAddress(params)); Sha256Hash hashForSign = transaction.hashForSignature(i, script, SigHash.ALL, false); ECDSASignature signature = eckey.sign(hashForSign); TransactionSignature tranSign = new TransactionSignature(signature, SigHash.ALL, false); scriptSig = ScriptBuilder.createInputScript(tranSign, eckey);
But it is not the same as the hex string generated by the client RPC, but I don't know where it is wrong.
I will be very grateful if you can help me.
