A Decentralized Identifier (DID) is a self-sovereign identifier controlled by the user, not dependent on any central authority.

How much does DID attestation cost?

Costs vary widely: on Ethereum L1 it can be $5-50 per attestation; on L2 or purpose-built chains it can be fractions of a cent.

How It Works

Each component has a specific meaning:

Different DID methods — The different did methods recorded for the patient or scenario being assessed.

Note: Interpret the did attestation cost result against the clinical thresholds and context described above.

How to Use

Enter the different DID methods for the patient or scenario you are assessing. Calculate the total cost of issuing and verifying decentralized identity attestations on various blockchains. Compare costs for KYC credential issuance, credential verification, and revocation across different DID methods. Use the did attestation cost result to inform your clinical assessment.
