Public blockchains are permissionless and allow anyone to participate. All members of the blockchain have the same rights to read, modify and validate the blockchain. People primarily use public blockchains to trade and mine cryptocurrencies such as Bitcoin, Ethereum, and Litecoin. Permissioned blockchains use an access control layer to control who accesses the network.
They are therefore characterized by network access restricted to a few authorized participants and by a validation process delegated to a small group of players. Consortium blockchains are permissioned blockchains where consensus processes are managed by a set of pre-selected nodes and they are also considered as "partially decentralized blockchains", however, fully private blockchains are private blockchains where access and write permissions are centrally managed by an organization. Hybrid blockchains combine elements of private and public networks in order to set up private and permission-based systems alongside a public system. In this way, control over access to the data stored in the blockchain is guaranteed, while keeping the rest of the data public.
Datome has an agnostic approach to blockchain technology, but in its standard version it natively integrates Hyperledger Fabric, a permissioned blockchain framework, and it is capable of being distributed on federated or consortium scenarios, and also hybridized with public or third-party blockchain networks.
