Abstract
Interactive distributed systems, such as high- frequency trading, augmented reality and online gaming, require low latency between users. Geographically-diverse replication is a common technique to decrease latency, but current de- ployment frameworks either target specific applications (e.g., content distribution networks are prevalent for static content), fail to provide fine-grained locality, (e.g., cloud services), or offer little support for consistency guarantees. We propose a framework applicable to general-purpose distributed systems that preserves locality between any pair of users interacting through the system, while providing strong consistency. We also suggest initial ideas to develop locality-preserving blockchains and the security challenges that arise
