A sovereign blockchain is a distributed ledger controlled and operated by a single nation-state or government entity. This type of blockchain is typically permissioned, meaning access and participation are restricted and managed by the governing authority. It aims to provide a secure, transparent, and auditable digital infrastructure for national purposes, such as issuing central bank digital currencies, managing digital identities, or recording public records. The design prioritizes national control, data privacy, and compliance with domestic regulations.
