Grandmaster Clock

A grandmaster clock serves as the primary source of time in a network running the Precision Time Protocol. It acts as the ultimate reference point to which all other devices in the trading network synchronize their own internal clocks.

In a financial ecosystem, the grandmaster is often linked to an external, highly accurate time source to ensure global consistency. This hierarchy prevents the fragmentation of time records, which is critical when multiple exchanges or liquidity pools must settle transactions.

The reliability of the grandmaster clock is a single point of dependency that requires robust redundancy and failover mechanisms.
