The start of the month brought a new release: Dave 3.0.0-alpha.4. Let's unpack what's under the hood.
But first, in case you don't know what Dave is and by now you're afraid to ask, here's the tl;dr. ↓🧵
1/ The fraud proof system, our Permissionless Refereed Tournament (PRT), is the mechanism that lets anyone challenge a dishonest computation onchain without trusting a single validator.
Optimistic rollups assume computations are correct by default, so there's a dispute period, and PRT is what resolves it.
2/ What's new in 3.0.0-alpha.4: PRT settlement is now two-phase, staged then accepted, giving the network a window to catch errors before they're final.
That window disappears if every sentry agrees with the staged result, skipping straight to faster finality.
3/ The prototype node has a name now: Sling, with persistent storage and event tracking.
PRT's ad-hoc tournament views were replaced by typed projections that expose the actual phase instead of reverting.
Also shipped: fairer payouts for tournament winners, deployment files moving to plain text, upgrades to the Cartesi Machine and Rollups Contracts, a newer Foundry, and stronger test coverage.
4/ Kudos to our contributors for the work on this. Full changelog here: https://github.com/cartesi/dave/releases/tag/v3.0.0-alpha.4
