Conversion of Bex32 Bitcoin Addresses in the Older Format Using Web3.js
When working with bitcoin, it happens that programmers and users have to switch between different formats. One of the Conversions Comes from the New Bex32 Bitcoin Address Format Used by Ethereum Blockchain (BEX32) To the Older, Bitcoin Segwit Address Format. In this article, we will examine how you can achieve this conversion using the popular javascript web3.js. Library.
Background
Before immersing perurselves in the conversion process, let’s quickly give the differentences between bech32 addresses and segwit:
* BEX32: Two -Part Address Format That Connects The Hexadecimal Key (Public Key) with Tag (Version). It is used by bitcoin core wallets and many other applications.
* SEGWIT:
Improving the Bech32 Format, which Data Into Smaller Fragments Called “Tags” and Adds Support for Many Signatures to the Block.
BEX32 Transformation Into Legacy Segwit Address
To convert the native bitcoin BEX32 Address to an older segwit format, you must take thesis steps:
- This will be used as a public key for the new address.
- Calculate the Block Number and Time Marker:
use the “Eth_blockknumer” and `
eth_timestamfunction to get the current block number and time marker. These Values Can Be Downloaded Using A Network Supplier Such As Infura Or Local API Blockchain Interface (E.G. Bitcoin Core Portfolio).
- Create a New Segwit Address: Construct the New Segwit Address Using the Following Format:
( ) ( ) (<...>)
Here is an Example of the Code to Start:
`JavaScript
Const web3 = Requires ("Web3");
Const Web3 = New Web3 (New Web3.providers.htttpprovider ('
// Separate the public key (Hexagonal String) from the Bech32 Address
Const Bech32Address = '12345678901234567890abdef';
Constickey = web3.eth.accounts.from rrawaddress (Bex32address, 0);
// Calculate the Block Number and Time Marker
Conste Blockknumber = web3.eth.blockknumber;
Const Timestamp = web3.eth.timestamp ();
// Create a New Segwit Address
Conste segwitaddress =$ {blockknumber} $ {timestamp} $ {publickey.tostring (16)} ($} {1}) ($ {2}) ($ {3}) ($ {4}) ($ {5} ) ($ {5})) ($ {6}) ($ {7});
console.log (segwitaddress);
`
*Remember to replace these substitute symbols with real values.
This fragment of the code shows how to separate the public key from the bech32 address, calculate the block number and time marker, create a new segwit address and print the result. By following this process, you can successully convert native bex32 bitcoin addresses to older segwit formats using web3.js.
Additional tips:
- When working with bitcoin, remember that some services may require additional configuration or configuration to use the bex32 addresses.
- Blockchain Ethereum has a limited number or blocks per second (about 15), which can affect performance. It may be necessary to adjust the code coperly.
- Always read the official web3.js Documentation and other Reliable Sources to Get Current Information on the latest Changes and the Best Practices.
By following this article, you should now be able to convert the bex32 bitcoin addresses to older segwit formats using web3.js. If you have any further questions or need additional help, you can ask!
