Say YES to sub-second zero-confirmation transactions and say NO to sub-second verifications.
By having one rotating leader establishing a order of event and still requiring all active nodes to verify a transaction before being placed on the blockchain allows for sub-second zero confirmation transaction to be achieved while still obtaining the security provided through a fully decentralized network.
A TPS of 100k + can be achieved as seen in other projects in which have a rotating leader.
Who says we can't have the best of both worlds?
We have updated or blog on how zero-confirmation transactions are achieved, take a look.
