=== Eventual consistency ===
 
An [[eventual consistency]]<ref name="Replica"/> is a weak consistency model in athe system with athe lack of simultaneous updates. It defines that if no update takes a very long time, all replicas eventually become consistent.
 
Most shared decentralized databases have an eventual consistency model, either BASE: basically available; soft state; eventually consistent, or a combination of [[ACID (computer science)|ACID]] and BASE sometimes called SALT: sequential; agreed; ledgered; tamper-resistant, and also symmetric; admin-free; ledgered; and time-consensual.<ref>Collin Cusce.
