- BlockchainHub Glossary (†807 s.v. "Private Blockchains"): a fully private blockchain is a blockchain where write permissions are kept centralized to one organization. Read permissions may be public or restricted to an arbitrary extent. Likely applications include database management, auditing, etc internal to a single company, and so public readability may not be necessary in many cases at all, though in other cases public auditability is desired.
- Stubbs and Ankeemana 2016 (†773 ): Private blockchains are equally feasible. Rather than being a decentralized database that can be updated by anyone, one or more central parties control who has the ability to update the ledger. These private blockchains gain transactional speed by having fewer parties needed to achieve consensus. However, they lose openness, distributed trust, and their resistance to falsified records through sheer scale of client participation. (†1956)
