Recovery of Ethereum Transactions: ListSynceBlock Parameter Explained
The ListSienceBlock parameter is a crucial part of Blockchain Ethereum, allowing users to recover a list of all block transaction from a specified block hash or all transactions if no block hash is provided. In this article, we will delve into the details of this parameter and its use.
What is lock lists'?
ListSnceBlockis an http request that recovers a list of all block transactions from a specified block hash or all transactions if no block hash is provided. This parameter is used by Web3.py, a popular Python library to interact with Ethereum blockchain, to look for Blockchain transactions.
** Arguments:1. “Blockhash” (...
* HASH BLOCK : The first argument is required and specifies the block's hash to start recovering transactions. You can use this to search for specific blocks or get all transactions if no block hash is provided.
*TARGET-CONFirmations
: Optional, the third argument specifies the target number of confirmations for each block before it is included in the answer. By default,Locking lists’ includes block transactions with less than 4 confirmations.
** Return value: 1. "List" (...
TheListSienceBlockparameter returns a JSON object containing a list of all transactions from the specified block hash or if no block hash is provided. The answer may include metadata such as block number, date and time record and transaction count.
Example of use:
Bash
Curl -x post \
\
-H ‘Type of Content: App/JSON’ \
-d ‘{“Key”: “VALUE”}’
`
In this example, replace your_project_id with your Infura Project ID. The server response would be in JSON format:
`Json
[[
{
“Blocknumber”: 1,
“Timestamp”: 1643723400,
“TransactiCount”: 100,
“Transactions”: […]
},
{
“Blocknumber”: 2,
“Timestamp”: 1643723410,
“TransactiCount”: 200,
“Transactions”: […]
}
]
`
In short, the ListSnceblock parameter is a powerful tool for recovering Blockchain Ethereum transactions. By providing block hash or omitting it and specifying destination confirmations, you can seek all relevant transactions or specific blocks with less than 4 confirmations.
