How this service works
Verify a block under the SuperRoot — chain 8453 block 51741679
Output
Returns a cryptographic proof verification result indicating whether the specified block on the given chain is valid and attested under the SuperRoot, including block validity status and attestation details.
Example use cases
Base chain block integrity check
“I need to verify that block 52180190 on Base (chain ID 8453) is valid under the SuperRoot — can you run a proof verification on it?”
Ethereum mainnet block proof
“Can you prove and verify block 19000000 on Ethereum mainnet (chain ID 1) to confirm its integrity under the SuperRoot?”
Arc chain block attestation
“Please verify block 1000000 on Arc chain (chain ID 5042) and confirm whether the proof checks out under the SuperRoot.”
Technical details
Endpoint
POSThttps://www.taifoon.io/api/skills/proof-verify-v5?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need cryptographic, SuperRoot-backed verification of a specific block on supported EVM chains (Base, Arc, Ethereum). Prefer this over generic RPC calls when you need a trustless proof rather than just block data, or when auditing block integrity in a trustless context.
Side effects
- Invalid or non-existent block number for the specified chain — returns error indicating block not found
- Unsupported chain_id — returns error for chains not covered by the SuperRoot
- Block not yet finalized or too recent — proof may be unavailable
- Payment failure or insufficient USDC — request rejected before processing
- Network timeout or SuperRoot unavailability — service temporarily unreachable
