Background
From a discussion in Core Devs Call 17, we will need a CIP to reduce block time from 12 to 6 seconds.
Proposed changes
Decrease block time from 12s to 6s: feat: decrease block time to 6s by jcstein · Pull Request #3953 · celestiaorg/celestia-app · GitHub
Benefits
This reduction in block time doubles throughput on Celestia!
2MB every 12 seconds → 2MB every 6 seconds.
Open questions
Do we need to modify ADR-19? I don’t think so, as this will go live after year 1.
Next steps
If this proposal has enough consensus, I will write a CIP to formalize it.
