At present Tezos block time is around 1 minute. But many other blockchains have faster block times or finality guarantees, both in the order of seconds.
What are the current bottlenecks related to lowering the block time to < 15 seconds? Or can we safely set it to a lower number?
For DeFi usecases(exchange, lending, etc…) - 1 minute blocktime feels a bit too long. For simple transfer usecases, 1 minute should work. But I feel for DeFi, it would be good to have faster blocktimes.
