understand the confirmation of transactions in Ethereum using the API of blockchain.info data
As an Ethereum developer, it is a crucial understanding of how transactions in the block chain are processed. In this article, we will deepen the method of determining the number of transaction confirmations and its speed using the API interface of blockchain.info data.
What are transaction confirmation?
Confirmation of transactions are a measure of how many times the block has been extracted and verified by the network before adding it to the block chain. This confirms that the sender of the transaction (also known as “sender”) really received the payment of the recipient (“recipient”).
How to determine the transaction confirmation using the blockchain.info interface Data API
Blockchain.info Data API provides a way to consult the Ethereum block chain and recover information about individual transactions, including confirmations. This way you can use it:
Step 1: Configure your blockchain.info account
Create an account on blockchain.info ( and check your e -mail address.
Step 2: Get your API key
After logging in, go to the “My Account” section. Click “API keys” and create a new API key for the application.
Step 3: Use the API of Data to get acquainted with transactions
You can use the following endpoint to recover transaction information using the API of data:
(txhash}
''
Replace{txhash} ‘for a real shortcut you want to consult. The “data” method is used for data recovery, and the TX parameter specifies that we are interested in transaction information.
Example of use:
`Bash
Curl -x Get \
''
Replacewith your real abbreviation of transactions.
how to determine the transaction confirmation using the API of data
JSON data will contain several fields, including "confirmations", which represent the number of confirmations for this block. To get the number of confirmations for a specific block, you can use the following consultation:
Bash
Curl -x Get \
''
Replacewith your real abbreviation of transactions.
How to know if any transaction confirmed and paid the extraction rate using the API of data
To check if a specific transaction has paid a miner's rate, you can use the "Fee" parameter in consultation. The "Fee" field contains information about the transaction award, which is the amount of ether that was awarded for miners to create this block.
Example of use:
Bash
Curl -x Get \
''
Replacewith your real abbreviation of transactions. JSON data will contain the "fee" field, which represents the amount of ether, which was paid to miners for creating this block.
Example of use: verification of transactions and rate confirmation using the API of Data
Suppose you create an application that must track transactions in the Ethereum network. You can use the API data interface to read the transaction information and determine whether a specific transaction has confirmed and paid a miner's rate.
` Python
Import requests
Api_key = “your_api_key”
Tx_hash = “
Headers = {
“Authorization”: f “carrier {api_key}”,
“Type of content”: “Application/Json”
}
Answer = Request.get (f ” (tx_hash}/confirmations? Fee = true”, headed = headers)
If the answer.status_code == 200:
date = answer.json ()
Confirmation = data [“confirmation”]
Fee_amount = data [“rate”] [“quantity”]
Print (f “transaction {tx_hash} confirmed {confirmation} times and paid $ {fee_amount: .2f} to miners.
