Block Verification Usage Guide

When you open the Explorer, you’ll see a live feed of Ethereum blocks as they’re verified and settled on FastSet.

The table gives you a block-by-block breakdown of the verification process.

Let’s walk through each column:

• Hash: This is the unique identifier for the claim itself. Each one links directly to the FastSet Explorer, where you can dive deeper into the raw claim data and settlement details.

• Type: Right now you’ll mostly see Computational Claims. These show that a block has been re-executed and proven valid by the verifier quorum. State claims appear when the chain tip is advanced. For a deeper look into how claims work including initializing and state update claims see the claims and verification model section of the docs.

• Block Number and Block Hash: These link back to Etherscan, so you can cross-check the original block on Ethereum. Think of it as a way to flip between the verified mirror inside FastSet and the chain it’s tracking.

• Time: The timestamp for when the claim was settled. This helps you trace when each block entered the verified history.

• Claim Details: Clicking View opens a detailed certificate. Here you can see:

  
• The quorum required for settlement.

• The committee of verifiers involved.

• The individual signatures collected.

• The validator certificate from FastSet proving the claim was accepted.

This certificate is the cryptographic backbone of the Explorer. It’s what makes each claim independently auditable.

The Account tab

You’ll notice an Account button in the top-right corner. This isn’t a personal account page (like you might expect on other apps). Instead, it’s leads to the FastSet explorer page.
