There are a number of different blockchain types and platforms. They are differentiated, for example, by whether they are private (closed group of participants), hybrid (mixed form) or public (open to all), or whether they are equipped with or without permission (possible accesses).

The choice of the appropriate blockchain platform depends on the respective industry and the specific business model of the company. For example, Corda, Open Chain, Quorum, Ethereum, Multichain, Stellar or Hyperledger Fabric can be mentioned here.
