It is surprising how fast the technology is being developed. Slowly we reach the Blockchain area 3.0. I would summarize the three stages of the Blockchain revolution from a technological point of view as follows:
Blockchain 1.0 - Bitcoin: It is basicaly the Bitcoin area, Blockchain had only one specific application for transferring money, with some other version and extensions like alternative cryptocurrencies.
Blockchain 2.0 - Generalization: As the platforms are getting extended to cover general application areas and Turing complete languages to write general Smart Contracts. A good example is for such a chain is Ethereum.
Blockchain 3.0 - Industrialization: Even general platforms are extended with elements providing the fast and efficient realization of industrial solutions. Platform like Azure Blockchain as a Service or Hyperledger do not really provide a Blockchain solution on their own. Despite they provide frameworks for several existing Chain solutions supporting several additional core services from hosting to authentication.
