conversion of bech32 bitcoin addresses to hereditary format using web3.js
When working with Bitcoin, it is not uncommon for developers and users to have to switch between different formats. One such transformation is from the new format at the address of the Bech32 Bitcoin, used by the Ethereum blockchain (Bech32), next to its hereditary counterpart, the format of Bitcoin Segwit. In this article we will study how you can achieve this transformation using the popular JavaScript Library Web3.js.
background
Before you immerse yourself in the conversion process, let us quickly summarize the differences between the addresses of Bech32 and Segwit:
* Bech32: Double -part format address that combines a hexagonal key (public key) with a marker (version). It is used by Bitcoin major portfolios and many other applications.
* SEGWIT: Improvement of the form of BECH32, which divides the data into smaller pieces called “tags” and adds support for multiple signatures per block.
Conversion of Bech32 into Legacy SEGWIT addresses
To convert your home address Bech32 Bitcoin to SEGWIT inheritance, you will need to follow these steps:
- Get Public Key (Hex String): Find the hexadecimal presentation of the first 34 characters in your address Bech32. This will be used as a public key for the new address.
- Calculate the block number and time mark:
Use the
ETH_BlocknumberandETH_Timestampfunctions to get the current block and time mark respectively. These values can be derived using a network provider such as Infura or Local Blockchain API (for example, the Bitcoin Core portfolio).
- Create a new SEGWIT: Construct a new SEGWIT address using the following format:
() () ()S
Here’s some sample code to get started:
`javascript
CONST Web3 = Requirement (‘Web3’);
CONST Web3 = New Web3 (new Web3.providers.httpprovider (‘
// Extract the Public Key (Hex String) from the address Bech32
Const bech32Address = ‘12345678901234567890ABCDEF’;
CONST public = web3.eth.accounts.fromrawaddress (bech32address, 0);
// Calculate block number and time mark number
Const blocknumber = web3.eth.blocknumber;
CONST TIMESTAMP = Web3.ETH.Timestamp ();
// Create a new SEGWIT address
Const segwitaddress = $ {blocknumber} $ {Timestamp} $ {public.Tostring (16)} ($ {1}) ($} ($}) ($} )) ($ {6}) ($ {7});
Console.log (segwitaddress);
`
Note: 1,2, 3, …,7 in the address of Segwit are substitutes for additional signatures that can be generated using the Ethereum portfolio or a separate service. Be sure to replace these substitutes with actual values.
This fragment of codes demonstrates how to retrieve the public key from the address Bech32, calculate the block number and the time mark, create a new SEGWIT address and print the result. Following this process, you can successfully convert native Beh32 Bitcoin addresses to Legacy Segwit formats using web3.js.
Additional Tips:
- When working with Bitcoin, it is essential to bear in mind that some services may require additional setting or configuration to use the Bech32 addresses.
- Ethereum blockchain has a limited number of blocks per second (about 15), which can affect productivity. You may need to adjust your code accordingly.
- Always consult the official documentation of Web3.js and other reliable sources for up-to-date information on the latest changes and best practices.
Following this article, now you need to be able to convert the Bitcoin addresses to the BEC32 to inherited Segwit formats using web3.js. If you have any further questions or need additional help, do not hesitate to ask!
