Ik “ben op geen enkele manier een expert op dit gebied (en mijn foutmelding was anders), maar ik heb vorige week geprobeerd om Bitcoinj ondertekent een transactie en verzendt deze in ruwe vorm (dwz zonder gebruik te maken van het transportprotocol dat Bitcoinj biedt) en dit is wat ik heb geleerd (op de moeilijke manier): Je kunt dergelijke transacties niet ondertekenen. Als je tx.addSignedInput in een lus aanroept, , zal je de handtekening van de transactie beschadigen en wordt deze ongeldig . De oplossing (na brainstormen met mijn team en het uitproberen van een paar recepten hier ( deze werkte niet), bij Bitcoin Stack Exchange) was voeg alle invoer toe aan de transactie en onderteken ze vervolgens handmatig .
Transaction tx = new Transaction(networkParams); tx.addOutput(Coin.valueOf(amount), targetAddress); addInputsToTransaction(sourceAddress, tx, unspents, amount); signInputsOfTransaction(sourceAddress, tx, key); tx.verify(); tx.getConfidence().setSource(TransactionConfidence.Source.SELF); tx.setPurpose(Transaction.Purpose.USER_PAYMENT); String valueToSend = byteArrayToHexString(tx.bitcoinSerialize()); en de methoden:
private void addInputsToTransaction(Address sourceAddress, Transaction tx, @NonNull BalanceResponse.Unspents[] unspents, Long amount) { long gatheredAmount = 0L; long requiredAmount = amount + TX_FEE; for (BalanceResponse.Unspents unspent : unspents) { gatheredAmount += unspent.getAmount(); TransactionOutPoint outPoint = new TransactionOutPoint(networkParams, unspent.getvOut(), Sha256Hash.wrap(unspent.getTxId())); TransactionInput transactionInput = new TransactionInput(networkParams, tx, hexStringToByteArray(unspent.getScriptPubKey()), outPoint, Coin.valueOf(unspent.getAmount()); tx.addInput(transactionInput); if (gatheredAmount >= requiredAmount) { break; } } if (gatheredAmount > requiredAmount) { //return change to sender, in real life it should use different address tx.addOutput(Coin.valueOf((gatheredAmount - requiredAmount)), sourceAddress); } } private void signInputsOfTransaction(Address sourceAddress, @NonNull Transaction tx, ECKey key) { for (int i = 0; i < tx.getInputs().size(); i++) { Script scriptPubKey = ScriptBuilder.createOutputScript(sourceAddress); Sha256Hash hash = tx.hashForSignature(i, scriptPubKey, Transaction.SigHash.ALL, true); ECKey.ECDSASignature ecdsaSignature = key.sign(hash); TransactionSignature txSignature = new TransactionSignature(ecdsaSignature, Transaction.SigHash.ALL, true); if (ScriptPattern.isP2PK(scriptPubKey)) { tx.getInput(i).setScriptSig(ScriptBuilder.createInputScript(txSignature)); } else { if (!ScriptPattern.isP2PKH(scriptPubKey)) { throw new ScriptException(ScriptError.SCRIPT_ERR_UNKNOWN_ERROR, "Unable to sign this scrptPubKey: " + scriptPubKey); } tx.getInput(i).setScriptSig(ScriptBuilder.createInputScript(txSignature, key)); } } } Ik hoop dat het je zal helpen.

- Verander waar naar vals, het werkt voor mij. Sha256Hash hash = tx.hashForSignature (i, scriptPubKey, Transaction.SigHash.ALL, false); ECKey.ECDSASignature ecdsaSignature = key.sign (hash); TransactionSignature txSignature = nieuwe TransactionSignature (ecdsaSignature, Transaction.SigHash.ALL, false);
