Ethereum, Neo, and Hyperledger are all technologies that have already attracted substantial traction from different projects. Any newcomers will have to not only offer a superior technology at the blockchain level but will also contend with the host of tools and existing libraries and tutorials that are already being developed. In particular, the Ethereum and Hyperledger ecosystems have a tremendous amount of investment dedicated to them, as well as the substantial corporate support. Both projects are the only ones to be offered by Microsoft and Amazon as blockchain-as-a-service offerings.
