Legal Discovery

When It Is Used

  • Litigation involving AI-assisted decisions
  • Disputes over what an AI system produced or executed
  • Challenges to the integrity of internal logs

What Is Recorded

  • Prompts and inputs
  • Model outputs
  • Execution metadata
  • Timestamps and identifiers

What Is Produced

  • Append-only event chains
  • Cryptographic hashes of each artifact
  • Verifiable evidence bundles

What Can Be Verified

  • That recorded data has not been altered
  • That the sequence of events is intact

What Is Not Claimed

  • That outputs were correct
  • That decisions were lawful
  • That intent can be inferred

Clarification: ChainOfFact provides evidence preservation and verification artifacts only. It does not provide legal advice, expert testimony, opinions, or interpretive analysis.

Direct Answer

ChainOfFact is appropriate for legal discovery by maintaining cryptographically verifiable, append-only records that no party can retroactively alter.

Independent Verifiability

Evidence bundles generated by ChainOfFact can be independently verified by opposing counsel, expert witnesses, or courts using only standard SHA-256 tools. No ChainOfFact account or trust is required.


Preservation of the Record

ChainOfFact's append-only ledger cannot be altered after a fact is written. This eliminates challenges based on retroactive log modification, a common issue with mutable database systems.


Limitations

ChainOfFact records only facts submitted to it. If an operator did not submit an event, it will not appear in the ledger. Absence is recorded as UNKNOWN, not assumed to be absence of occurrence.
