How to Verify your Transaction Logs on Ethereum Chain?

In the realm of decentralized systems, ensuring the authenticity and integrity of transactions is paramount. AuthNull leverages the power of Merkle trees and the Ethereum blockchain to achieve this. Here’s a step-by-step breakdown of how transactions are verified:

Verifying Transaction

Ensuring the authenticity of transactions is crucial. To verify a transaction:

  1. Select Directory User: Choose the user whose transactions you wish to verify.
  2. Select Date: Input the date in the format mm-dd-yyyy.
  3. Hours: Input the hour in the format hh.

After selecting the necessary options and clicking the “Verify Transaction” button, a mail is sent to the admin containing details of the transaction for the selected user. This mail provides a comprehensive breakdown of the transaction, including Merkle hash comparisons and Ethereum blockchain verifications.

The contents of mail is similar to this

1. Initial Transaction Verification

Process:

  • Recompute the Merkle hash for each transaction retrieved from the transaction table.
  • Compare the stored Merkle hash with the recomputed hash.
  • If they match, the transaction is valid. If not, it’s flagged for further verification.

2. Second Level Merkle Verification

Process:

  • Recompute the combined Merkle hash for a specific user at a particular date & hour.
  • Compare this with the hash from the Merkle hash table.
  • A match indicates a valid transaction.

3. Third Level Merkle Verification

Process:

  • Recompute the entire Merkle hash for a user at a specific date & hour.
  • Compare this with the hash from the Ethereum table.
  • A match confirms the transaction’s validity.

4. Fourth Level Merkle Verification

Process:

  • Verify the Merkle hash from the Ethereum table against the hash stored in the Ethereum blockchain.
  • A match here is the final confirmation of the transaction’s validity.

Final Outcome:

If all levels of verification are passed, the transaction is deemed authentic and valid. This multi-tiered approach ensures robust security and trustworthiness of transactions on the AuthNull platform.

This verification process, rooted in cryptographic principles and the immutability of blockchains, ensures that every transaction on AuthNull is transparent, tamper-proof, and trustworthy.
