What is a Transaction ID (TXID)?

A Transaction ID (TXID) is a unique identifier assigned to a specific transaction on a blockchain network. In blockchain technology, each transaction is given a unique identifier, the TXID, to distinguish it from other transactions.


TXIDs are typically a long string of alphanumeric characters and are generated using cryptographic hashing algorithms. These IDs serve multiple purposes, including tracking the status of transactions, verifying the integrity of transactions, and facilitating auditing and analysis of blockchain data.

Because each transaction has a unique TXID, it becomes easy to trace and verify the details of a particular transaction on the blockchain. Users and developers can use TXIDs to look up specific transactions on blockchain explorers or through APIs provided by blockchain networks.

Techopedia Explains the Transaction ID Meaning

In a simple definition, Transaction ID serves as a unique identifier for each transaction conducted on a blockchain network. It is generated using cryptographic hashing algorithms, which transform transaction data into a fixed-length alphanumeric string.

TXIDs play a fundamental role in the transparency and accountability of blockchain transactions. They provide a means for users to track the status and details of transactions, including the sender, recipient, timestamp, and transaction amount.

Furthermore, TXIDs facilitate the process of confirming transactions on the blockchain. When a transaction is broadcasted to the network, miners or validators work to include it in a block by solving complex mathematical puzzles.

How is Transaction ID Used?

TXIDs serve as fundamental tools for tracking, verifying, and ensuring the integrity of transactions within blockchain networks.

When a transaction is initiated, it undergoes verification and validation by network participants, often referred to as miners or validators. Once confirmed, the transaction is assigned a unique TXID generated through cryptographic hashing algorithms.

One primary use of TXIDs is to track the status and details of transactions. Users can reference TXIDs to monitor the progress of their transactions, from the moment they are broadcasted to the network to their eventual inclusion in a block.

By querying the blockchain with the TXID, individuals can ascertain whether a transaction has been confirmed, the number of confirmations it has received, and other relevant details such as sender and recipient addresses and transaction amounts.

Moreover, TXIDs play a crucial role in verifying the authenticity and validity of transactions. Each TXID is unique to its corresponding transaction and is generated based on the transaction’s specific data, such as inputs, outputs, and timestamps.

This cryptographic uniqueness ensures that TXIDs cannot be forged or tampered with, providing a reliable method for confirming the integrity of transactions. Network participants can verify the legitimacy of a transaction by cross-referencing its TXID with the blockchain’s immutable ledger.

Additionally, TXIDs facilitate auditing, analysis, and forensic investigations of blockchain data. Researchers, developers, and auditors utilize TXIDs to analyze transaction patterns, track the flow of assets, and identify anomalies or suspicious activities on the blockchain.

By examining TXIDs and associated transaction details, analysts can gain insights into the behavior of network participants, detect potential fraud or double spending attempts, and ensure compliance with regulatory requirements.

Can Transaction IDs Be Tracked?

Yes, Transaction IDs can be tracked within blockchain networks. Users can track transactions by referencing their corresponding TXIDs through blockchain explorers or other tools provided by blockchain networks.

Blockchain explorers allow users to search for transactions using their TXIDs and retrieve detailed information about each transaction, including sender and recipient addresses, transaction amounts, timestamps, and the number of confirmations received.

Furthermore, because blockchain transactions are transparent and publicly accessible, anyone can trace the flow of assets by examining the transaction history associated with each TXID.

However, it’s essential to note that while TXIDs themselves are publicly accessible, the identities of the parties involved in a transaction may not always be readily apparent. Blockchain transactions are pseudonymous, meaning that transactions are associated with cryptographic addresses rather than real-world identities.

Where to Find Transaction ID Number?

There are different ways to find the TXID number associated with a transaction. Here are some more common ways:

Wallet or Transaction History
Users can find the TXID in their transaction history if they initiated the transaction through a cryptocurrency wallet or exchange platform. This information is often available alongside other transaction details such as timestamps, amounts, and recipient addresses.

Blockchain Explorer
By entering the sender’s or recipient’s address or the transaction hash, users can retrieve the TXID and view detailed information about the transaction, including its status and associated metadata.

Transaction Confirmation Notification
In some cases, especially when using a cryptocurrency exchange or wallet service, users may receive a confirmation notification for their transaction. This notification often includes the TXID as part of the transaction details.
API or Developer Tools
For developers or advanced users, blockchain networks often provide APIs or developer tools that enable programmatic access to transaction data. By querying the blockchain network using these tools, they can retrieve the TXID and other transaction details programmatically.

How Transaction IDs Help With Chargeback Management

Transaction IDs serve as essential tools in chargeback management, offering merchants and payment processors a reliable means of tracking, verifying, and resolving disputed transactions.

When a customer initiates a chargeback, claiming that a transaction was unauthorized, fraudulent, or defective, the transaction ID serves as a unique identifier that allows merchants to quickly locate and review the details of the transaction in question.

Once the transaction ID has been identified, merchants can use it to verify the legitimacy of the transaction and gather relevant information to support their case during the chargeback dispute process.

By cross-referencing the transaction details associated with the transaction ID, including the transaction amount, date, time, and customer information, merchants can determine whether the chargeback is valid or if there has been a misunderstanding or error. This helps merchants build a comprehensive case and provide evidence to refute invalid chargeback claims.

Transaction IDs also play a pivotal role in communication and documentation throughout the chargeback management process. When merchants respond to chargeback requests or disputes, they often need to provide documentation and evidence to support their position.

Furthermore, they serve as reference points in correspondence, allowing merchants to accurately identify and discuss specific transactions with payment processors, banks, and customers. Additionally, transaction IDs enable merchants to maintain detailed transaction records, which can be invaluable for tracking the progress of chargeback disputes.
