Vellum

Vellum is built around did:ckb, an identifier a person controls on CKB rather than an account a platform controls for them. Its dashboard lets you create and manage a did:ckb identity with wallet-signed transactions on CKB mainnet or testnet, and share a public profile.

The next layer is reputation: communities and products attach Claim Cells, authorized by the issuer's did:ckb and held under the builder's own lock, for work such as merged GitHub contributions or community activity. Anyone can read the claims and apply the published scoring rules, so the record does not depend on Vellum's own database. The reputation protocol and dashboard currently run on CKB testnet.
