What is Sparrow Chain

SparrowChain is a platform which is building key technologies based on Blockchain and Machine learning to solve problems in how people collaborate and work together.

We are following the best engineering practices to build features that have practical applications across various industries and sectors while ensuring they are decentralised, interoperable, cost efficient, seamless and trust less.
