Verifiable Trust Concept
Building a native trust layer for the internet through verifiable credentials and cryptographic proof of identity, authenticity, and ownership.
On-chain rules, off-chain proofs
Concept
The Verifiable Trust concept relies on a hybrid trust model, combining web3, DIDs and Verifiable Credentials.
On-Chain Rules
Ecosystems publish their Decentralized Identifier (DID), governance framework, trust registries, credential schemas, and issuer/verifier lists on-chain.
Off-Chain Proofs
Ecosystems prove off-chain control of their DID by updating their DID Document. Only the DID controller can do this.
Benefits
Ledger Benefits
Public, transparent information
Immutable history
Token-based business models
DID + VC Benefits
Data doesn't have to be public
No personal data stored on-chain
DID verification is straightforward
Example
Ecosystem did:example:ecosystem created a trust registry and a credential schema on-chain. To prove ownership, they will refer to the trust registry and attach a verifiable credential to their DID Document.
Ecosystem DID Self-Issues Verifiable Credential
Ecosystem DID will self-issue a Verifiable Credential to prove control over the on-chain credential schema:
{
"@context": [
"https://www.w3.org/ns/credentials/v2"
],
"id": "https://ecosystem/shemas-example-jsc.json",
"type": ["VerifiableCredential", "JsonSchemaCredential"],
"issuer": "did:example:ecosystem",
"issuanceDate": "2024-01-01T19:23:24Z",
"credentialSchema": {
"id": "https://www.w3.org/ns/credentials/json-schema/v2.json",
"type": "JsonSchema",
"digestSRI": "sha384-S57yQDg1MTzF56Oi9DbSQ14u7jBy0RDdx0YbeV7shwhCS88G8SCXeFq82PafhCrW"
},
"credentialSubject": {
"id": "vpr:verana:mainnet/cs/v1/js/12345678",
"type": "JsonSchema",
"jsonSchema": {
"$ref": "vpr:verana:mainnet/cs/v1/js/12345678"
},
"digestSRI": "sha384-ABCSGyugst67rs67rdbugsy0RDdx0YbeV7shwhCS88G8SCXeFq82PafhCeZ"
}
}Ecosystem DID Document Service Entries
Ecosystem DID Document will contain references to the verifiable presentations and trust registries:
"service": [
{
"id": "did:example:ecosystem#vpr-schemas-example-jsc-vp",
"type": "LinkedVerifiablePresentation",
"serviceEndpoint": ["https://ecosystem/schemas-example-jsc-vp.json"]
},
...
]Generalizing the Concept: Proof-of-Trust
The Proof-of-Trust doesn’t just apply to ecosystems, it extends to every participant and service:
Every service is identified by its own DID
Services collect multiple verifiable credentials from different ecosystems
Apps display a clear Proof-of-Trust snapshot

Proof-of-Trust
DID Directory
To make all this work, Verana also provides a public DID Directory:
Register
Anyone can register their DID on-chain
Index
Verana Resolver indexes, verifies credentials, and stores results
Query
Apps and search engines can query this verifiable database
