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.
