New paper from the amazing researchers @Subzero_Labs
Consensus upgrades are painful and dangerous.
Yet new consensus algorithms popup every couple or so years. How does one keep up?
We designed a system (Gauss) that makes adopting new consensus easy & safe!

āPrivacy is the one feature thatās critical for the worldās finance to move onchain.ā
Privacy pulls user identity information on-chain.
Identity information gets compliance on-chain.
Compliance brings the worldās finance on-chain.
Worldās finance gets everyone on-chain.

Concurrency control, while really hard to implement correctly, should not be difficult to understand!

One of the most important web3 challenges today, that should have been solved yesterday, is privacy for general purpose transactions!

A common question we get is how @RialoHQ transactions suspend to go offchain and magically resume processing onchain?
Well we have privacy-preserving async transactions
It's all about continuations that feel natural to web2 devs. The way it was meant to be
Full demo soon š¤«

Outstanding interactive visualizer from @aleak which demonstrates Optimistic vs Pessimistic Concurrency Control!
@RialoHQ supports both modes giving developers maximum flexibility based on their use case!
This interactive demo will be live soon for anyone to play with!
