Introduction to Attestations via Ethereum Attestation Service (EAS)
Last updated
Attestations are a powerful concept in blockchain technology, allowing one entity to make verified claims about another or about specific data on the blockchain. The Ethereum Attestation Service (EAS) is an open-source, permissionless platform that enables the creation, verification, and management of these attestations on or off-chain.
Attestations are essentially digital signatures that vouch for certain attributes or facts. They can be used for:
Identity Verification
Reputation Systems
Compliance Checks
Ownership Proofs
And much more!
A simple boolean attestation that verifies a wallet belongs to a real person.
A more secure attestation that uses Merkle root hashes to verify identity documents while preserving privacy.
Verification: An attester (like Zipwire) verifies your information
Recording: The attestation is recorded on the blockchain
Verification: You can later prove specific attributes without revealing the underlying data
The blockchain only stores the attestation and its Merkle root hash, not your actual data
You can selectively reveal specific attributes using cryptographic proofs
The system maintains your privacy while ensuring verifiability
Privacy: Share only what you need to share
Control: You decide what information to reveal
Portability: Use your attestations across different platforms
Security: Cryptographic proofs ensure your data hasn't been tampered with
Trust: Verify user information without storing sensitive data
Compliance: Meet regulatory requirements while respecting privacy
Efficiency: Reduce the need for repeated identity checks
Security: Prevent fraud and identity theft
Connect Your Wallet: Link your Ethereum wallet to Zipwire
Choose Your Attestation: Select between IsAHuman or Private Data attestation
Complete Verification: Follow the verification process
Claim Your Attestation: Add it to your wallet
Use Your Attestation: Share it with platforms that need verification
