Except for WOOT, which CRDT for co-editor does not require causal ordering?

[gritzko]

RON CT/RGA may consume inputs in arbitrary order.

Some background on the Causal Tree (CT) that gritzko is referring to: http://archagon.net/blog/2018/03/24/data-laced-with-history.

In the original paper of RGA, RGA does require that operations are received with respect to the causal ordering. And RGA preserves causality by state vector technique.

Are you the inventor of CT?
