SALT (database systems)
Post-development of distributed databases and distributed ledger technologies such as blockchain, there was found to be a descriptive gap between the traditional consistency models of ACID and BASE. Database researchers Stefan Tai, Jacob Eberhardt and Markus Klems of Technische Universität Berlin[1] created a model, SALT, to describe this new transactional paradigm. This consistency model developed a characterisation of distributed ledgers as a middle ground between ACID isolation and the eventual consistency of BASE transactions, with its own unique properties.[2]
Transactions in distributed systems can be defined as:
- Sequential
- Agreed
- Ledgered
- Tamper-resistant
Distributed systems can be defined as:
- Symmetric
- Admin-free
- Ledgered
- Time-consensual
