Creating A SegWit Transaction With The Bitcore Node: Guide to Solving Problems
Problems while using the “Bitcore-lib” Package to create and sign Bitcoin transactions. One of the most common challenges is an attack to use the segwit function introduced in Bitcoin core 26.1. Segwit Transactions Using the Same NPM Package.
Problem: Legacy Transations
“Bitcore-lib”, it seems that they do not support segwit by default. This is not based on the Older Bitcoin Core Protocol, which does not support segwit natively. However, some npm packages were created to fill this gap.
Solution: Using “Bitcore-Segwit”
Package (available at the website [ Package /Bitcore -Segwit)). This
Step by Step Guide
Here is a step-by-step guide on how to create and sign segwit transactions using “Bitcore-Liband" Bitcore-Segwit ":
- Install the required packages : start the following command in the terminal:
Bash
NPM Install Bitcore Libseweed
2.
`JavaScript
const {transaction} = requires ("libseaved");
Const BitcoRelib = Requires ('./ Bitcore-lib');
// Create a New Wallet (e.g. from a private key)
Let the Wallet;
to try {
Const private = "your_private_key_here";
Wallet = Waiting for Bitcrealib.createWallet (Private);
} Catch (Error) {
Console.Error (Error);
}
// Create a New Transaction
Const tx = New Transaction (
Wallet.address,
[New BitcoindAdddress ("1.2.3.4:1234"), // Sender Address]
);
// Set The Segwit Flag for Transactions
tx.setsegwises ([
{Type: "Publickey", Privatey: Privatey},
]);
//
Const signature = expect bitcoRelib.signtransaction (TX, "your_new_private_key_here");
In this example:
- We create a wallet using “bitcore-lib” and store it in a variable “Wallet”.
- We create a new transaction using “libseaved”.
- This says “libseaved” to use a private key as a public key in the transaction.
- Finally, we sign a transaction using a new private key.
Check the Transaction
Code:
`JavaScript
const {transaction} = requires ("libseaved");
Const BitcoRelib = Requires ('./ Bitcore-lib');
// Create a New Wallet (e.g. from a private key)
Let the Wallet;
to try {
Const private = "your_private_key_here";
Wallet = Waiting for bitcellelib.createwallet (private);
} Catch (Error) {
Console.Error (Error);
}
// Create a New Transaction
Const tx = New Transaction (
Wallet.address,
[New BitcoindAdddress ("1.2.3.4:1234"), // Sender Address]
);
// Set The Segwit Flag for Transactions
tx.setsegwises ([
{Type: "Publickey", Privatey: Privatey},
]);
//
Const signature = expect bitcoRelib.signtransaction (TX, "your_new_private_key_here");
// Check the Transaction
Const Verificationtx = New Transaction (
Wallet.address,
tx.hash,
);
Wait for verificationtx.verify (signature);
If the translation is successfully verified, you should see a message indicating that the transaction has been confirmed.
