Bitcoin: Creating a raw Segwit transaction from scratch and getting Signature must be zero for failed CHECK(MULTI)SIG operation

Creating A Raw Followed Transaction From Scratch: Understanding The Check (Multi) Sig Operation

As Bitcoin’s Mainnet Continues to Evolve, New Features Like Segregated Witness (SegWit) and Multi-Signature Wallets Become Increasingly Important. One key aspect of these updates is the check (fines) SIG Operation, which enables more secure and efficient transaction verification. However, understanding how this process works from scratch can be a bit overwhelming for beginners.

In this article, we will dive into the World of SegWit Transactions, Specifically Exploring How To Create Followed Transactions On Testnet From Scratch and Performing A Check (Multi) Sig Operation.

What is a saw followed transaction?

Before we dive into the process, it’s essential to understand what a saw followed transaction looks like. A have been followed by transaction is a binary-encoded message that represents the state of a block on the Bitcoin Blockchain. This format is designed to be more efficient and second compared to the traditional merkle tree-based transactions.

The Check (Multi) Sig Operation

The check (fines) SIG Operation is a crucial step in verifying the signature scheme for SegWit Transactions. It ensures that the requirement number of signatures are present, making it difficult for an attacker to forge or tamper with the transaction.

To perform a check (fines) sig operation, you will need to:

• Create a new Followransaction object using theBitcoin :: Followed :: Create_New_Transaction Function.

• Set up the required signatures by callingSet_Multisig_Secretand Set_signatureson the transaction.

Creating A Raw Followed Transaction From Scratch

HERE'S AN EXAMPLE CODE SNIPPET IN C ++ THAT DEMONSTRATES How To Create A Raw Followed Transaction From Scratch:

cpp

#include

#include

You are Main () {

// Create a New Bitcoin Transaction Using Bitcoin :: Followed :: Create_New_Transaction.

Followed :: Transaction TX;

if (tx.create (New STD :: String ("Testnet"), 0, 0)) {

Bitcoin_log_error ("Failed to Create Transaction");

// Set Up the Required Signatures

Followed :: SIGS SIGNATORS = Bitcoin :: Followed :: Create_signatures (tx.get_hash (), 2);

tx.set_multisig_secret (sigs);

// Create a New Raw Followed Transaction Object.

Followed :: Transaction raw_tx = Followed :: Make_ransaction (TX, 0);

Return 1;

}

Bitcoin_log_debug ("Raw followed transaction created successfully");

Return 0;

}

Performing A Check (fines) Sig Operation

To perform a check (fines) Sig Operation, you need to create a new SegWit :: Transaction 'Object using the Bitcoin :: Followed :: Create_New_Transaction Function and set up the required signatures. HERE’S AN EXAMPLE CODE SNIPPET:

“ cpp

#include

#include

You are Main () {

// Create a New Bitcoin Transaction Using Bitcoin :: Followed :: Create_New_Transaction.

Followed :: Transaction TX;

if (tx.create (New STD :: String (“Testnet”), 0, 0)) {

Bitcoin_log_error (“Failed to Create Transaction”);

// Set Up the Required Signatures

Followed :: SIGS SIGNATORS = Bitcoin :: Followed :: Create_signatures (tx.get_hash (), 2);

tx.set_multisig_secret (sigs);

// Perform a check (fines) Sig Operation.

Bool Found_all_sigs = False;

While (! Found_all_sigs) {

Bitcoin_log_debug (“Check (Multi) SIG Operation:”);

Followed :: Transaction New_TX = Followed :: Make_ransaction (TX, 0);

// check if the required signatures are present in the new transaction.

Followed :: SIGS_NEW SIGNATORS;

if (new_tx.get_signatures (sigs_new)) {

Bitcoin_log_debug (“Check (Multi) SIG Operation: Found All Required Signatures.
