Validity relies on Blockchain technology

Decentralised

The signature is stored on the blockchain, and is therefore not centralized, for maximum security.

Unalterable

It is impossible for anyone to modify the signature once stored on the blockchain.

Timestamped

Each insertion of a signature is accompanied by a UTC timestamp, directly supported  by the blockchain.

Auditable

Access to the signature can be done independently of the Validity service. It is thus very easy to carry out an audit.
