One of the most critical components in the blockchain ecosystem is the TXID (Transaction ID). A TXID is a unique cryptographic hash generated from raw transaction data within a blockchain network. It serves as an immutable identifier for tracking, verifying, and preventing duplicate transactions.
What Is a TXID?
A TXID (or transaction hash) is a string of characters uniquely identifying a blockchain transaction. It is generated through cryptographic hashing and can be used to verify:
- Amount sent
- Transaction date
- Sender/receiver addresses
- Network confirmations
Examples of Historic TXIDs:
- First Bitcoin transaction (Satoshi Nakamoto to Hal Finney):
f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16 - Bitcoin Pizza transaction:
cca7507897abc89628f450e8b1e0c6fca4ec3f7b34cccf55f3f531c659ff4d79
You can explore these transactions using blockchain explorers like Blockchain.com or Blockchair.
Why Is TXID Important?
- Transaction Tracking: Locates transactions within specific blocks.
- Verification: Confirms transaction execution and integrity.
- Dispute Resolution: Helps resolve issues like failed transfers.
- Data Integrity: Any alteration to transaction data changes the hash, ensuring tamper-proof records.

How to Find and Use a TXID
Steps to Generate a TXID (Bitcoin Example):
- Data Preparation: Compile sender/receiver addresses, amount, and metadata.
- Signing: Authorize the transaction with a digital signature.
- Hashing: Process data via SHA-256 to create a unique hash (TXID).
Locating TXIDs on Exchanges (e.g., INDODAX):
- Website: Navigate to Wallet > History > Select asset > Check Description column.
- Mobile App: Go to Wallet > Search asset > View transaction details.
Tips for Using TXIDs Effectively
- Monitor Status: Track confirmations via blockchain explorers.
- Support Requests: Provide TXIDs for faster dispute resolution.
- Security: Double-check addresses before submitting transactions.

FAQ Section
1. Can a TXID be altered?
No—TXIDs are cryptographically secure. Any change to transaction data invalidates the hash.
2. How long does a TXID take to generate?
Instantaneously upon transaction submission.
3. What if my TXID isn’t visible?
Check your exchange’s Transaction History or contact support.
4. Is a TXID the same as a transaction hash?
Yes, the terms are interchangeable.
Conclusion
TXIDs are foundational for secure, transparent blockchain transactions. By leveraging them, users can verify transactions, resolve issues, and ensure data integrity.
