What does it mean for a blockchain to be asynchronous?
summary
Asynchronous backing is rolling out on Rococo soon and it lets collators pre-produce parachain candidates so blocks can be authored 6 to 12 seconds before relay inclusion, reducing relay block time from 12s to 6s block time and increasing authoring windows. Backers remain bonded and slashing economics stay intact (validators roughly $10M DOT bonded, parachain lease ≈ $1M), assigned redundantly in groups of five. Initial params are max candidate depth = 3 and allowed ancestry length = 2. Roadmap targets 500 validators/100 cores, then 1,000/200 cores and support for 1,000+ parachains.
