@vladzamfir good hanging out briefly at Ethereal Summit 2018. as you recall, you and i had a convo near the food trucks about what Gitcoin could bounty in order to help you move forward, faster. You said an implementation of CBC-Casper would really help you work out the kinks in the spec and help you build documentation.

What do you think of the above spec? I will fund it with 1.5 ETH once we both feel good about thet spec.
