ZKValidator run a block producer on Mina and also created the Mina-VRF-rs. The mina-vrf-rs is a tool built by Kobi Gurkan, and independent contributor Chris Lin as part of ZKValidators contribution to the Mina Protocol. It allows delegators to evaluate the performance of block producers by determining whether the block producer produced all the blocks they could win. Block producers can also use this tool to predict the time slots they will be eligible to produce blocks in the future to improve their own performance. It can also be used to understand the reason why a block wasn’t produced when the producer had the opportunity to. The team also produce a regular twitter space featuring news and information from many current zk projects. Twitter: @ZKValidator mina-vrf-rs GitHub link github.com/zkvalidator/mina-vrf-rs
