-This BEP will not change the fast finality mechanism, but short block interval could bring challenges fast finality, as votes need to be propagated in a shorter time.

When fast finality works properly, with this BEP, the average transaction finality time would be reduced from 7.5 seconds to 3.75 seconds.
 But if fast finality failed, with TurnLength 16 and ValidatorSize 21, for natural block finality, it will be:
-- (>1/2 validator confirm):  176(11*16) blocks, that is 264 seconds
-- (>2/3 validator confirm):  240(15*16) blocks, that is 360 seconds

 BEP-520 is the phase one to reduce the block interval from 3 seconds to 1.5 seconds. And this BEP is the phase two, which would reduce it further to 0.75 seconds.
 
 ## 3. Motivation
-Faster transaction confirmation is a critical and long term goal, with 0.75 seconds block interval, it could meet the requirement of some time sensitive application.

 After phase two, the block interval will be reduced to 0.75 seconds, a single validator will produce 32 consecutive blocks per turn, keeping the total block production time at 24 seconds (0.75 × 32). However, the shorter block time significantly reduces the collaboration window for searchers, builders, and validators, impacting the current process and requiring adjustments.
