A blockchain transaction does not explain every off-chain claim behind it. Signed records can add source and document context where your application needs evidence from outside the chain.

## Asset platforms: Identify the source of an off-chain statement

An asset description may reference documents whose source and version are unclear.

### What to record

Sign the statement and document fingerprints under an identified issuer, linking the record to the application’s asset reference.

### What to review

Check issuer, integrity, and status, then independently examine the real-world asset and the authority behind the claim.

### The outcome

A traceable statement without treating a signature as proof of asset ownership.

## Community governance: Record the evidence shared for a proposal

Proposal documents can change while participants discuss or review them.

### What to record

Record the proposal package fingerprint, submitting identity, version, and relevant review references before the decision process.

### What to review

Compare the package under discussion with the recorded version and identify revised materials explicitly.

### The outcome

A shared reference for which proposal information was presented to participants.

## Web3 infrastructure: Trace actions by connected off-chain services

An application may rely on automated services without a clear record of their reported work.

### What to record

Give each service an identity and create receipts for configured tasks, input references, and reported outcomes.

### What to review

Inspect the receipts alongside independently checked chain events and investigate discrepancies through the application’s operations process.

### The outcome

A view of the off-chain activity surrounding an integrated workflow.

## Before you begin

Define the issuing identities and external references your application will trust. Chain access, wallets, and any transaction execution require separate integration and authorization.
