Anaïs Querol here, Cryptography Engineer at O(1) Labs. The community call presenting MIP#3: Kimchi, a new proof system has just happened. Here you can find the slides and the recording of the meeting.
Thanks for the slides. I’m quite surprised to see that a shorter block time is not planned with the much faster Kimchi launch. 3 min is a long time for a block to be generated. what’s the reasoning behind this please?
The reason behind Kimchi is not directly to reduce the block time, but to add functionalities that facilitate zkApps in Mina. Kimchi is mainly a change in the proof system, the cryptographic part of Mina, whereas the time for a block to be generated depends on many other factors related to the protocol itself like the consensus algorithm. With the improvements shown in Kimchi, we anticipate a shorter proof generation for transaction SNARKs, but circuits encoding zkApps could be potentially larger. On average, I would say that the time to have a new block will be similar than the current one.
