ArcBlock is a computing platform for developing and deploying blockchain applications, Ethereum is a blockchain technology. They are related but are very different. Comparing ArcBlock to Ethereum is like compare Apple to Orange.
To achieve high-performance transactions, we built an optimized blockchain dedicated to ArcBlock’s own token services and the public ledger. The design goal is to achieve >100,000 Tx/s, which is more than adequate for a wide range of applications. In the future this blockchain could be improved for broader purposes.
