Even though a lot of blockchain implementation are decentralized and distributed, Oracle introduced a centralized blockchain desk function in Oracle 21c database. The Blockchain Desk in Oracle 21c database can be a centralized blockchain which give immutable characteristic.

Also, consortium blockchains can offer bigger security and reliability than non-public blockchains, as the consortium users work with each other to take care of the network. Some samples of consortium blockchains consist of Quorum and Hyperledger.[76]
