Connect to Bitcoin Network to Ethereum
While developing a feature of the RailS online wallet, you are probably interested in connecting to Bitcoin network using the official Ethereum API. In this article, we will go through the process of establishing a bond with a bitcoin client and use it for various tasks.
Bitcoin client review and Ethereum API
Before you dive into the copies of the code, quickly review the basics:
- Bitcoin client is responsible for connecting to Bitcoin network and communication with miners.
- Ethereum API provides a set of holiday API to interact with Ethereum blockchain.
Connect to Bitcoin Network using Ethereum API -JA
To connect with the Bitcoin network, you will have to authenticate your requirements by providing “Ethernaut” accounts and passing phrases with 12 words. You can get these credentials through the official [Ethereum Developer Portal] (
Here’s an example of how to establish a relationship with a bitcoin client using the Ethereum API:
`Ruby
require ‘net/http’
Set credentials to authenticate
Account = ‘Your_account_address’
Passphrase = ‘YouR_Passphrase_12_words_long’
Construct URL Requests for the endpoint Bitcoin API
URL = “
Set HTTP header with authentication credentials
Heads = {
‘Contents-Tip’: ‘Application/Json’,
‘Authorization’: ‘Basic#{base64.encode (‘ EtherNAut:#{account}:#{Passphse} ‘)})}
Iche
Construct Json-Rpc Body Requires
Params = {
‘Method’: ‘listtransation’,
method we are interested in. In this example, we will list all transactions.
‘Args’: [],
empty string for now.
‘Params’: [
{‘method’: ‘GettransationCount’, ‘Param1’: ‘Blocknumber’},
{
‘Method’: ‘Listalltransactions’,
‘ARG0’: [‘Blockhash’]
Iche
]

Send a Bitcoin API Request
Answer = net :: http.get_response (URL, header)
`
Reactions of transactions
Once you have established a relationship with a bitcoin client, you can download transactions using theGettransationCount ‘method, and then indicate all transactions by method oflistlltransactions.
`Ruby
Params [: ARGS] << 'Blocknumber'
List the block number.
Send a Bitcoin API Request
Answer = net :: http.get_response (URL, header)
Parse answer as json
Data = json.parse (answer.body)
Retrieve transactions
Transactions = data [‘listlltransactions’] [‘all’]
Print the ID -Ove and transaction details
Transactions.each do | Transaction |
puts “transaction ID: #{transaction [‘id’]}, transaction hash: #{transaction [‘hash’], 8}.”
end
`
Block retrieved
To retrieve blocks, you can use theGettransationcountCountwith Parametrom Blocknumberto get the block number for which you want to download the information.
Ruby
Params [: ARGS] << 'Blocknumber'
List the block number.
Send a Bitcoin API Request
Answer = net :: http.get_response (URL, header)
Parse answer as json
Data = json.parse (answer.body)
Retrieve the number of transactions for that block
Count = Data [‘GettransationCount’] [‘result’] [0] [‘transactionation’]
Print the transaction number and hash
puts “counting transactions: #{County}, hash: #{Data [‘GettransationCount’] [‘hash’]. Split (‘.’. ‘). Last}.”

Conclusion
Establishing a bond with a bitcoin client using the Ethereum APIs allows you to interact with Blockchain and retrieve different data. In this article, we walked through the process of installing credentials for authentication, constructing the URL of requests and sending a request in Bitcoin API. We also gave examples of the coin to download transactions and blocks.
