🔏DID Digital Identity (Based on SBT)

Identity Design

• Each user generates a DID when registering and mints non-transferable Soul Bound Tokens (SBT).

• SBT records health achievements, credit ratings and community contributions.

Achievement System

• Milestone Rewards: Check in for 90 consecutive days and invite users who meet the requirements → receive a commemorative SBT badge.

• SBT becomes the user’s “digital health business card”.

Data privacy protection

• Health data is stored in an encrypted manner, with only hashed credentials remaining on the chain.

• Users can independently authorize a third party (such as an insurance company) to query records without revealing details.
