Bitcoin transactions monitoring via websockets
While you are looking to monitor all transactions on the Bitcoin network, you came across a promising solution. The URL supplied http: // blockchain.info / api_websoCket is indeed a valid API termination point which allows you to subscribe to the real -time updates of the Bitcoin blockchain.
In this article, we decompose what this API offers and how you can use it to monitor all transactions on the Bitcoin network.
What can I do with this API?
The API http: // blockchain.info / API_WEBSOCKET provides a websocket termination point which allows real -time streaming of Bitcoin blockchain data. With this API, you can:
- Subscribe to transaction updates : Subscription to specific channels (for example,tx
,blockortransaction) and by adding the Ethereum address of your customer as that a listener, you will receive updates when new transactions are disseminated or used.
- Monitor The addresses and their corresponding transaction history : you can subscribe to the channels for individual addresses and receive real -time updates on the history of their transaction, including the time of each transaction and its value.
Prerequisite
Before diving into this API, make sure:
- Your Bitcoin client is connected to the network.
- Your Ethereum client is configured to send transactions to the specified address (if applicable).
- You have the authorizations required to access Bitcoin Blockchain data.
Configuration of the API connection
To usehttp: // blockchain.info / API_WEBSOCKET ‘API, you will have to:
- Register for an API key on the blockchain.info site.
- Create a new websocket termination point with your client’s Ethereum address as a auditor.
- Configure the channel subscription settings (for example, type of transaction and address) in your JavaScript code.
Code example (JavaScript)
`Javascript
Const Websocket = require ('WS');
Const WSS = New Websocket.Server ({Port: 8080});
wss.on ('connection', (ws) => {
Const Address = 'Your_ethereum_address'; // replaces by Ethereum address you want to listen to
ws.on ('message', (data) => {
Console.log (Receives transaction data from $ {address}: $ {data});
// Process and display the data received in real time
});
});
// Subscribe to channel transactions
wss.on ('open', () => {
Const = {
Channel: "TX",
address,
};
wss.subscribbe (subscription, (error) => {
if (error) {
Console.error (error is subscribed to $ {subscription.channel}: $ {error});
} other {
Console.log (Subscribed to $ {subscription.CHANNEL} to $ {address});
}
});
});

Bitcoin transactions monitoring
To monitor all Bitcoin transactions on the network, you can subscribe to several channels and update your customer's display in real time. For example:
- Subscribe to the tx channel for individual addresses
- Subscribe to the “Block” channel for block creation events
- Subscribe to the transaction channel for transaction updates
Using this API, you can monitor all Bitcoin transactions on the network, including new blocks, mining events and transaction updates.
Conclusion
The API `http: // blockchain.info / API_WEBSOCKET provides an exciting solution for real -time monitoring of Bitcoin transactions. By following these steps and examples, you can configure your client’s websocket termination point and start receiving Bitcoin blockchain updates. Do not forget to replace the Ethereum address in the code example with your own address and configure channel subscriptions according to your needs. Good surveillance!
