STH is a distributed secure data storage public blockchain, based on the POC consensus algorithm which it upgrades to DPOC (Delegated Proof of Capacity) "capacity algorithm proof." Starhole Chain leverages its own advantages: low data acquisition latency; simple and effective data update algorithms; high fault tolerance in data update algorithms, to collaboratively manage the computing power of data storage mining machines on the Starhole public chain. It sets up multi-port, multi-threaded smart API interfaces, and will become a practical, distributed data management and computing intelligent public blockchain for applications.
