Hybrid or federated blockchain
This type of blockchain is a merger between public and private blockchain. It is an attempt to take advantage of the best of both worlds. In these blockchain, participation in the network is private. In other words, access to network resources is controlled by one or more entities. However, the ledger is publicly accessible. This means that anyone can explore block by block everything that happens on said blockchain.
For example, these types of blockchain networks are very useful for governments or business organizations that want to store or share data securely. A perfect use case is happening in the healthcare sector, where blockchain is starting to be used to store data from its drug production lines. The stored data can be reviewed by the competent authority in order to control quality, both at the same company and government level. The objective of applying this blockchain model is to maintain a high level of transparency and trust.
Features of hybrid or federated blockchain
Among the characteristics of this type of network we can mention:
- Access to the network is restricted to elements that can only be authorized by the rest of the control units
- Access to the transaction book or any other means of information generated by the blockchain is public
- There is no mining or cryptocurrency. The consensus of the network is given by other means that ensure that the data is correct
- It is partially decentralized which leads to a better level of security and transparency
