    Current multiplayer developers use two very different transaction frameworks: slow but robust revision control for code, and very loose but fast networking protocols for game state interchange. The need for global transaction consistency will force these to converge.https://twitter.com/TimSweeneyEpic/status/1076229994018422787 …

    The four hard problems any Metaverse framework will have to solve are transactions, data persistence, code isolation, and forward compatible code evolution. And it will have to solve them at vast scales of concurrency. Nothing even remotely resembling this exists yet.

        Again, I've long felt that this is one of the advantages the web has going for it - we've been dealing with global transaction consistency at massive scales, and built many tools to make it work. Much of that infrastructure can replace/augment traditional game server architecture

        Take a look at Holochain. It’s basically a protocol for building distributed networks that can provide flexible robust transaction consistency, either fully Byzantine fault tolerant or otherwise if desired. 1/2

        The key here is in propagation of transactions for validation to only a need-to-know subset of the network; a sensible method of sharding, sharing global state via a distributed hash table. There are other evolving solutions coming out of the blockchain/DLT world too... 2/2

        Also data persistence could similarly be solved via a solution akin to BigChainDB albeit with a consensus protocol that’s fully BFT, instead of tendermint. Make this a permissioned federated DB and your consensus models’ game-theoretical constraints simplify well for perf

        What about something like SpatialOS? Is it in the right direction? It seems as a means to focus more "awareness" on parts of said metaverse that require heavy volume transactions by borrowing it from where there is less necessary transactions and move fluidly between both?

        Come to think of that, something small studios doing F2P games have to think about, is cost of the online experience. Most engines and middle-ware provide support for client-server networking, but this becomes costly with small rooms 1/

        One approach is to make all logic deterministic and if latency in operations is OK this allows you to use basically just a message broker as your server. It still allows replays of command streams for validation and discrepancies between match results can detect cheating 2/
