What is Aergo? Aergo is an open-source enterprise platform that can be used for hybrid deployment. The platform is built and utilized by Blocko, a South Korean technology company that has deployed production solutions for large-scale clients including Lotte Card, Shinhan Bank, Korea Exchange, and more. What use cases are there? The Aergo Chain is designed for use in enterprise use cases. Aergo has a smart contract engine. The Aergo mainnet is powered by a Byzantine Fault-Tolerant Delegated Proof-of-Stake mechanism, while the private ones are powered by a Proof-of-Authority consensus mechanism. The future services of Blocko will be based on Aergo products. An example use case includes a solution for credit card verifications. The solution was built using a version of Aergo's Lua smart contracts, which has reportedly saved Lotte Card 90% of their security expenditures.
