What Aqua Enables

Cryptographic proof of authenticity without intermediaries.

Data Accountability

Track every revision with cryptographic precision. Complete provenance for your documents.

Access Control

Share documents with specific wallets. Granular permissions and sharing contracts.

Identity Claims

DNS verification, ENS resolution, and attestation-based identity management.

Notarization

Ethereum timestamping for immutable proof. Documents anchored on-chain.

How It Works

Portable Hash-Chains

Aqua creates AquaTrees that record a complete history of data revisions with cryptographic precision.

Immutable Timestamps

Optional Ethereum timestamping provides additional verification and immutability.

Decentralized Trust

Aqua liberates certification from institutional gatekeepers through open cryptographic standards.
