User Profile ID Data

A Profile ID comprises the following:

• The address(es) of the generated smart contract accounts (initially Polygon and Solana).

• An email associated with the Profile ID - this is useful for organisations issuing credentials who maintain a database of the recipients' emails, such as a University.

• A URL linked to their Profile ID (https://www.profile.io/{Profile ID}).

• A Decentralised Identifier (DID). This is a key component of SSI and is used to cryptographically pair a Verifiable Credential to an identity.

• Web3 DNS Address - either subdomain or standard url.

• Once verified, a verified member badge.

• Algorithmic proof of personhood score for trust mechisms.

• A linked EOA address, such as a MetaMask account (subject to certain rules) or;

• A linked ENS account (such as profile.eth). Only one linked account is permitted per Profile ID.

DIDs are constructed in accordance with W3C standards. A sample of a DID issued on Ethereum appears as follows:
