Ethereum, any further lessons?

[Bobcrypto]

Launched in 2015, Ethereum is the largest and most well-established, open-ended decentralized software platform that enables SmartContracts and Distributed Applications (ĐApps) to be built and run without any downtime, fraud, control or interference from a third party. Ethereum is not just a platform but also a programming language (Turing complete) running on a blockchain, helping developers to build and publish distributed applications. And more to this? Your thoughts.
