Single source of truth
A single source of truth, often abbreviated as SSOT is a discipline or pragmatic approach to store data in only one place. This one place, doesn't mean that the data has only one copy, but the way data being retrieved and presented are always going through a single channel(See 3-2-1 Backup Rule )[1], often managed by a version control system.
The Entropy Pool
To relate Single source of truth in physical reality, the notion of a shared clock, or more technically, the idea of a common entropy pool, is essential to achieve this goal. A well-known example in setting up one large entropy pool is Bitcoin's blockchain.
