Identity Score

Overview

A score is an identity analysis of a user’s web3 & web2 behaviors. It is also a numerical value representing one or multiple Verifiable Credentials. The IdentityHub uses verifiable credentials to calculate these scores, and uses scores to match DID use cases with their desired audience. Scores provide a more granular assessment, filtering, or segmentation of the user, but are also less exclusive. However, they are more refined and complex than credentials. Every credential on the IDHub has its score and users that match the requirement of the credential can unlock it to rack up their score. Verifiable credentials generated by the Heima Network are attestation for user identification, they’re anonymous yet trustless.

Scoring dimensions

Scoring dimensions play a crucial role in providing a comprehensive and nuanced understanding of the factors that contribute to the overall score of a user within Heima's Identity Hub. These dimensions serve as distinct aspects or characteristics, essentially acting as building blocks for the final score assigned to an individual. They offer a detailed overview of the diverse elements that collectively shape a user's identity and trustworthiness within the Web3 ecosystem.

Each credential associated with a user is tagged with a specific identifier or tag. These tags act as labels or markers that categorize the credentials based on their nature or the type of information they represent. This categorization is a key organizational mechanism that allows for a more efficient and insightful assessment of a user's score without the need to individually scrutinize every single credential.

Examples of scoring dimensions:

Web 3 Anything that proves Web3 activity

Web 2 Anything that proves Web2 activity

Humanity Anything that proves authentic human activity

Activity Anything that proves activity

Holdings Anything that focuses on the holdings of assets

How to Calculate VC value

The Heima Identity Hub calculates verifiable credential scores based on the VC format. This means that the calculation format is not fixed. Scores are calculated for VCs that return assertions in boolean or count

• For boolean, the weight is put on either True or False, e.g. y(if(value=T/F))

For example, those from theoneblock assertion, points are allocated if the outcome of the claim is positive or truthful.

• For count, we will put weight directly based on the count, e.g. x(value), or put a threshold on the count and weight on it, e.g. z(if(value>n))

For instance, holding HEI token for 0 to 1 year might yield 5 points, 1 to 2 years might get 10 points, and so on.

Score Logic

Heima's score logic is a meticulous blend of scoring dimensions, weighted verifiable credentials, assertion description, etc., that underpins Heima's innovative approach to decentralized identity scoring. The IDHub community score is the first and one of the numerous scores of the IdentityHub, by showing the specific score logic components, we provide a detailed understanding of the various VCs, their descriptions, and associated score points. It also shows the issuers and data providers so that users can gain insights into how the scores are calculated.
