Glurk is an open credential protocol on Solana where data flows both ways. Every app that reads a user's identity must contribute something back — enforced at the program level, not by terms of service.
How it works
01
Any registered app requests read access to a user's verified credentials — financial skills, activity history, reputation.
02
The request_access instruction requires a data_contribution in the same transaction. No contribution = no access. Enforced on-chain.
03
The user's wallet must co-sign the transaction. No silent data harvesting. Every read is a visible on-chain event.
On-chain flow
app.requestAccess(
user: wallet.publicKey, // must co-sign
fields: ["credit-score", "stocks"],
contribution: { // REQUIRED — or tx fails
slug: "trading-history",
tier: "gold",
score: 85,
}
)
Protocol layers
Credential Layer
Approved issuers write verified facts about users. Each credential is a PDA: issuer × user × slug. Staq Financial Literacy is the first live issuer — real users, real on-chain credentials.

Access Layer
Reciprocal read/write enforcement. Apps must contribute to read. Users must sign to consent. request_access writes the contribution and the consent record atomically.
request_access · consent PDA · revoke_access
Intelligence Layer
Glurk Score — a 0–1000 reputation number derived from all credentials across all issuers, weighted by tier and score. Gets richer as more apps interact with the profile.
