## Identifier Persistence

Identifier Persistence refers to the requirement that a DID remains valid and resolvable over the long term, regardless of changes in the underlying infrastructure. In financial markets, identity must be stable to support long-dated derivative contracts or historical record-keeping.

If an identifier were to disappear, the ability to verify historical transactions or enforce contract terms would be compromised. Persistence is achieved by anchoring DIDs to robust, decentralized networks that are designed to last for decades.

This stability is a core expectation for any identity system used in institutional or long-term financial planning. It ensures that the link between an identity and its associated activity remains intact throughout the lifecycle of an asset.
