If the block time is changed to 6 seconds, it needs to be synchronized to the tally platform backend, which is currently configured for 12 seconds. cc @hackfisher @AurevoirXavier

IIRC KTON staker also utilizes block time?

If the block time is reduced to 6s, a migration for the acount-migration, staking and deposit may be needed. I remember that some locks are tight with block time.

No longer necessary after DIP-6.
