Some of the more interesting takes on this are GunJS and it's associated stack (sea, rad, dam etc - https://github.com/amark/gun https://github.com/amark/gun) It tries to come from a different direction ie. Local database with distributed sync upwards. It's only at the higher levels that it makes use of blockchain to ensure network QoS (axe). Croquet didn't focus quite so much on the infrastructure but looked at the collaboration aspect. Written in smalltalk it has some interesting ideas https://en.m.wikipedia.org/wiki/Croquet_Project https://en.m.wikipedia.org/wiki/Croquet_Project Discoverability in both is an issue but I think an eventual project will have to take ideas from both.
