What is the DID approach in TradeTrust?

Decentralised identifiers (DIDs) enable businesses to establish trust and verify the authenticity of digital identities without relying on a central authority. This can be particularly useful for secure and efficient interactions with customers, partners, and other entities, while giving businesses more control over their digital identity infrastructure.

The DID approach is recommended for verifiable documents. The issuance of normal/verifiable documents does not incur a gas fee, as there is no need to write on the blockchain. Learn more.

However, revoking the issued verifiable document will require setting up a document store and, hence, incur a gas fee. Learn more.
