In the infrastructure of distributed ledger technology, transparency and verifiability are the core pillars that establish trust in a decentralized system. According to experts at Tan Phat Digital, Transaction ID (TxID), also known under technical terms such as Transaction Hash (TxHash) or Transaction Identifier, serves as a unique "digital fingerprint" for each activity that takes place on the blockchain network. In essence, this is a string of letters and numbers created through cryptographic algorithms to identify, track and secure transaction information, acting as a permanent, unchangeable proof of the transfer of value between entities.
Technical basis and formation mechanism of TxID
The formation of a TxID is not a random process but the result of applying cryptographic hash functions (cryptographic hash functions) to the raw data of the transaction. These hash functions are responsible for converting variable-sized inputs into a fixed-length output, typically 64 characters in hexadecimal format.
Mathematical properties of hash functions in transaction identifiers
To ensure that a TxID functions effectively as a unique identifier, hash functions must adhere to strict mathematical principles:
Determinism (Determinism):The same input data—including sender address, recipient address, asset amount, gas fee, and nonce—will always produce an identical TxID. This allows every node in the network to independently calculate and validate transactions without the intervention of a third party.
Avalanche Effect: The slightest change in transaction data, for example a change of $0.00000001$ in asset units, will result in a completely different TxID. This feature prevents any attempts to cheat or change information after the transaction has been signed by the user's private key.
Collision Resistance: The possibility of two different transactions generating the same TxID is extremely low, almost zero in current computing practice. This ensures that each digital receipt is unique across the entire history of the blockchain.
Analysis of common TxID generation algorithms
Each blockchain network chooses a different hashing algorithm based on security and performance requirements. Below are the detailed differences analyzed by Tan Phat Digital:
SHA-256 Algorithm (Used for Bitcoin):
Structure: Based on Merkle-Damgård structure.
TxID generation process: Apply double hashing (Double SHA-256) on the raw data of transaction.
Output length: 256 bits (64 hex characters).
Security: US military standard (designed by NSA), extremely robust against brute-force attacks.
Performance: Greatly optimized for specialized mining devices ASIC.
Keccak-256 Algorithm (Used for Ethereum, BNB Chain):
Structure: Use sponge construction.
TxID generation process: Apply Keccak-256 single hash on data fields encrypted according to RLP (Recursive Length) standard Prefix).
Output length: 256 bits (64 hex characters).
Security: Highly rated in NIST SHA-3 competitions, resistant to length extension attacks.
Performance: Suitable for complex calculations in virtual machine environments EVM and smart contracts.
The strategic role of TxID in Blockchain governance and operation
TxID is not simply an identifier string but also an essential tool to maintain stable operation:
Verification and control of transactions: Allows users to check the status of a transaction through block explorers (Blockchain Explorers). The recipient can use the TxID to confirm whether the balance has actually been transferred, instead of having to completely trust the sender's assertions.
Dispute resolution: In commercial transactions, the TxID serves as an irrefutable receipt. Because blockchain is immutable, once the TxID has been included in the block, no one can change that information, creating a solid basis for resolving claims.
Technical troubleshooting: For exchange platforms, the TxID is the key for them to find data in the internal ledger system. When a user deposits money but does not see the balance, providing a TxID helps the support staff determine whether the error is in the network or the exchange's processing.
In-depth analysis of USDT: Network standards and how to check
Tether (USDT) exists on dozens of different blockchain networks. This diversity requires users to clearly distinguish standards to avoid losing assets.
Differences between ERC20, TRC20 and BEP20 standards
Each type of USDT has a different address format and fee mechanism:
USDT-ERC20 (Ethereum):Runs on the official Ethereum network. TxIDs usually start with the prefix
0x. The receiving wallet address also begins with0x. Transaction fees (gas) are typically the highest but offer the most optimal liquidity and security.USDT-TRC20 (Tron): Most popular for small and private transactions thanks to extremely low fees and near-instant confirmation speeds. The identifying feature is a wallet address starting with the letter
T.USDT-BEP20 (BNB Smart Chain): Low fee solution compatible with Ethereum. The wallet address also starts with
0x, which is easy to confuse with ERC20 if you do not carefully check the network on the BscScan block explorer.
Multi-network USDT TxID check procedure
To check correctly, you need to follow these steps:
Determine the network: Based on sending/receiving address or selection when making a transaction (T for Tron, 0x for Ethereum/BSC).
Go to the correct Explorer:
Ethereum Network: etherscan.io
Tron Network: tronscan.org
BNB Chain Network: bscscan.com
Solana Network: solscan.io
Analysis of displayed information: The explorer will provide status (Success, Pending, Failed), confirmation number (Confirmations) and actual transaction fees paid to miners.
Detailed instructions on how to find TxID on popular platforms variables
Below are the specific navigation steps updated by Tan Phat Digital for 2026:
On centralized exchanges (CEX)
Binance: Access Wallet -> Transaction History. Find the corresponding deposit or withdrawal order, click on it to copy the TxID string.
OKX: Log in, go to Assets -> Order History (Order Center). Select the Withdraw or Deposit tab, click the Details button to get the TxID (usually displayed as Hash).
Bybit: Go to the Funding account history page, select the Withdrawal or Deposit tab. The TxID will be displayed after the transaction reaches "Sent" or "Completed" status.
MEXC: Go to Wallet -> Funding History. Select the Withdrawal tab, the TxID will be in the detailed data table of each transaction.
On personal electronic wallets (Self-custody Wallets)
MetaMask: Open the application, select the Activity tab. Click on the transaction and select "View on block explorer" to get the TxHash right at the top of the page.
Trust Wallet: Select the cryptocurrency just traded, click on the history record, the TxID code will be in the details section.
Ledger Live: In the left menu, select Operations. Click on a transaction to open the details window showing the TxHash and gas fees.
Phantom (Solana Network): Go to the activities tab, select the transaction and look for the text Transaction Signature—this is Solana's TxID identifier.
Case analysis: TxID on the TON network (The Open Network)
The TON blockchain has a very different infrastructure, where operations take place as sequences of messages.
Transaction Hash: A unique hash for the execution at an account, including state changes and fees.
Message Hash: Each message (in or out) has its own hash. The TON ecosystem uses the Normalized Message Hash (TEP-467) standard to ensure consistency when looking up.
How to look up: Users usually use the Tonkeeper wallet and click on the "Transaction" button to be taken to the Tonviewer explorer. Here, you can view the "Trace" mode to see the entire message flow between smart contracts.
Transaction lifecycle and TxID states
Pending: The transaction is in the mempool, not yet included in the block.
Confirming: The transaction has is included in the block. Each new block is then counted as a confirmation.
Success: The transaction reaches the required number of confirmations and becomes immutable.
Failed: The transaction fails due to running out of gas or violating contract conditions. Fees are still deducted but funds are not transferred.
Resolving Stuck Transactions: RBF and CPFP Techniques
When a transaction is stuck because the gas fee is too low, you can apply:
Replace-by-Fee (RBF): Replace the old transaction with a new transaction with a higher fee but the same nonce. Miners will prioritize high-fee transactions and cancel old transactions.
Child-Pays-For-Parent (CPFP): The recipient creates a "child" transaction from the pending balance of the "parent" transaction with a very high fee, forcing the miner to process both to get the fee from the child transaction.
Security and fraud prevention related to TxID
Tan Phat Digital especially warns users about fraudulent tricks:
Fake emulators: Bad guys create screenshots or fake websites with a real-looking TxID to trick sellers into releasing assets in P2P transactions. Always check the TxID yourself on official Explorers.
Wallet address attack: Fraudsters create a wallet address with the same first and last characters as your wallet to fool you when you copy the TxID from your history. Always carefully check each character of the TxID and destination address on the block explorer.
Asset recovery process when sent to the wrong network
If sent to the wrong network, the TxID is the only evidence to start the recovery process:
1. For Binance:
Supports depositing to wrong network or missing Memo.
Processing fee: From $1$ USDT to $20$ USDT.
Processing time: $5 - 30$ days.
2. For MEXC:
Support for recovering assets from the wrong network or not listed.
Fixed processing fee: $50$ USDT.
Processing time: Can be up to $22$ working days.
3. For Bybit exchange:
Recovery support if asset value exceeds $500$ USD.
Processing fee: Fixed $200$ USD or withdrawal fee is $5 times higher.
Processing time: $7 - 14$ working days.
4. For BitMart:
Fee classification based on network complexity.
Fee level: Ranging from $5$ USDT to $500$ USDT depending on the specific case.
Transaction ID (TxID) is an integral component of the blockchain architecture, acting as a bridge between raw data and information verification needs. Mastering how to find and analyze TxIDs on block explorers is not just a technical skill, but also the ultimate asset protection solution in the digital economy. Hopefully, through this article by Tan Phat Digital, you have enough knowledge to confidently manage all your blockchain transactions.
