algorithm - Differences between OT and CRDT - Stack Overflow

Both approaches are similar in that they provide eventual consistency. The difference is in how they do it. One way of looking at it is:
– OT does it by changing operations. Operations are sent over the wire and concurrent operations are transformed once they are received.
– CRDTs do it by changing state. Operations are made on the local CRDT. Its state is sent over the wire and is merged with the state of a copy. It doesn’t matter how many times or in what order merges are made - all copies converge.
