How to check a transaction on blockchain

Understanding Blockchain Transactions

Before we dive into how to check transactions on blockchain, it is important to understand what a transaction is. A transaction on blockchain is a record of an exchange between two parties. This exchange can be anything from the transfer of funds to the execution of a smart contract. Transactions are verified and recorded on the blockchain, creating an immutable and transparent ledger that tracks all transactions on the network.

Common Types of Blockchain Transactions

There are several common types of transactions that occur on blockchain networks. These include:

• Bitcoin transactions: Bitcoin transactions involve the transfer of cryptocurrency between two parties. These transactions are recorded on the Bitcoin blockchain and can be verified by anyone with access to the network.
• Ethereum transactions: Ethereum transactions involve the execution of smart contracts on the Ethereum blockchain. Smart contracts are self-executing programs that automate complex processes and can be used for a wide range of applications, from supply chain management to voting systems.
• Altcoin transactions: Altcoin transactions involve the transfer of other cryptocurrencies on the blockchain. These transactions can occur between two parties or involve the execution of smart contracts.

Checking Transactions on Blockchain: Best Practices and Common Mistakes

Now that we have a basic understanding of blockchain transactions, let’s discuss how to check transactions on blockchain. There are several best practices that developers should follow when checking transactions on blockchain, including:

1. Use a Blockchain Explorer

A blockchain explorer is a web-based tool that allows you to view and search for transactions on the blockchain. There are many different blockchain explorers available, but some of the most popular include Blockchair, Blockstream, and CoinGecko.

When using a blockchain explorer, be sure to double-check the transaction details before proceeding. This includes verifying that the correct parties are involved in the transaction, that the correct amount of cryptocurrency is being transferred, and that there are no errors or discrepancies in the transaction data.

2. Check for Confirmations

Confirmations are a way for the blockchain to verify that a transaction has been processed correctly and is included in the immutable ledger. The number of confirmations required for a transaction to be considered valid varies depending on the blockchain network, but it is generally recommended to wait for at least 6 confirmations before assuming that the transaction has been processed successfully.

3. Verify Transaction Signatures

Transaction signatures are used to prove the authenticity of a transaction and prevent fraud or unauthorized access. When checking transactions on blockchain, be sure to verify that the correct parties have signed off on the transaction and that there are no signs of tampering or fraud.

Common Mistakes to Avoid when Checking Transactions on Blockchain

While checking transactions on blockchain can be a powerful tool for developers, there are also several common mistakes that should be avoided. These include:

• Not Verifying Transaction Details: It is crucial to double-check the details of a transaction before proceeding. This includes verifying that the correct parties are involved in the transaction, that the correct amount of cryptocurrency is being transferred, and that there are no errors or discrepancies in the transaction data.
• Not Waiting for Confirmations: Confirmations are an important way to ensure that a transaction has been processed correctly and is included in the immutable ledger.
