Creating a RAW -Segwit event from the beginning to new: Check (Multi) SIG -Operation Understanding **

Although Bitcoin’s protagonist has evolved, new functions, such as a separate witness (segwit) and multi -tier letters, are increasingly important. An important part of these updates is the SIG process (Multi), which allows for a more safer and more efficient event check. Understanding this process from scratch can be a bit overwhelming for beginners.

In this article, we immerse yourself in the world of Segwit events and explore how Raw -Segwit Testnet will create from scratch and perform the Many Sig (Multi).

What is the raw Segwit event?

Before we handle the process, it is important to understand what the Rohe Segwit will look like. The Raw Segwit event is a Binary coded message that represents the condition of the Bitcoin block chain block. This format is more efficient and safer compared to traditional events based on Merchle.

Check (many) sig function

The SIG operation (Multi) is a crucial step to check the signature system for Segwit events. It ensures that the required number of signatures is available, which makes it difficult to guarantee or manipulate the trade.

To perform (multi) sig surgery you have:

Create the new « Segwittransaction » object « Bitcoin :: Segwit :: CREATE_NEW_TRANSAVETION ».

Insert the necessary signatures by inviting set_multisig_secret and the set_signures.



 Creating a raw Segwit event from scratch  **

Here's an example -code -nippet in C ++, which shows how to create a raw segwit event from scratch:

Cpp



#clude 

#Clude 

INT Main () {

    // Create a new Bitcoin event with Bitcoin :: Segwit :: CREATE_NEW_TRANSATION.

    Segwit :: Transaction TX;

    if (tx.create (new std :: string ("testnet"), 0, 0)) {

        Bitcoin_log_error ("Event not created");

        // Set the necessary signatures

        Segwit :: Signatures SIGS = Bitcoin :: Segwit :: CREATE_SIGNATURES (tx.get_hash (), 2);

        tx.Set_multisig_secret (sigs);

        // Create a new RAW Segwit event object.

        Segwit :: Transaction Raw_tx = Segwit :: Make_Raw_Transaction (TX, 0);

        Return 1;

    }

    Bitcoin_log_debug ("Raw Segwit successfully created");

    Return 0;

}

Check (Multi) SIG operation

To complete the (Multi) SIG operation, you need to create a new object « Segwit :: Transaction » « Bitcoin :: Segwit :: CREATE_NEW_TRANSAK » and set the necessary signatures. Here is a sample code ragement:

« Cpp

#clude

#Clude

INT Main () {

// Create a new Bitcoin event with Bitcoin :: Segwit :: CREATE_NEW_TRANSATION.

Segwit :: Transaction TX;

if (tx.create (new std :: string (« testnet »), 0, 0)) {

Bitcoin_log_error (« Event not created »);

// Set the necessary signatures

Segwit :: Signatures SIGS = Bitcoin :: Segwit :: CREATE_SIGNATURES (tx.get_hash (), 2);

tx.Set_multisig_secret (sigs);

// Power a check (multi) SIG operation.

Bool Found_all_Sigs = False;

While (! Found_all_Sigs) {

Bitcoin_log_debug (« Check (Multi) SIG function: »);

Segwit :: Transaction New_tx = Segwit :: Make_Raw_Transaction (TX, 0);

// Check if the necessary signatures are available at the new event.

Segwit :: Signatuurs sigs_new;

if (new_tx.get_signures (sigs_new)) {

Bitcoin_log_debug (« Multi) SIG function: All necessary signatures found.
