How do you ensure accuracy in online games with dynamic and varying network latencies? How do you minimize desync events by causally ordering events from different nodes? How do you build horizontally-scalable backend services for multi-player games? How do you ensure scalability, synchronicity and persistence in the metaverse? The answer to all these questions starts in one place: highly accurate software-based time synchronization. Built upon technology developed at Stanford University, we will discuss the details of the Clockwork's clock synchronization system and demonstrate its operation. The system provides orders of magnitude better synchronization than standard NTP, requires no hardware support and scales to a large number of servers and across long distances. It is currently used by financial services firms for fairness in electronic trading, for accurately logging market data and for fine-grained network monitoring.
Accurate and scalable clock synchronization can help game developers with laborious and thorny problems like rollback. It can enable new ways of managing the multi-player experience. For engineers, it can simplify game development while reducing the cost of labor.
