Blockchain’s immutable record signifies that the information on the attempted exit can’t be deleted or altered by anyone and law enforcement and/or civil society can act upon this evidence.

Using blockchain to help prevent human trafficking: the system is able to record every exit with a minor – attempted at the border by an adult who’s not in the circle of trust – whose attestations do not match.

Personally Identifiable Information (PII) is never stored on the chain: it is only the assertions or the verifiable claims made about the person. This multi-source identity is built through trustworthy attestations about relationships established over time.

Information is validated and structured in the form of blocks, which then constitute a chain – the blockchain – a distributed, record-keeping, immutable ledger. Because of its distributed structure, it is virtually impossible to break into the entire system and alter or forge the records.
