In this next phase, engineers will build out the Merge logic and test their software with other teams on short-lived devnets. The engineers will vet the specs as they stand today and provide dynamic feedback into the specs to refine and\/or fix issues as they arise.<\/p>\n<p class=\"chakra-text css-gi02ar\">At the top of the list is to validate and refine the <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/execution-apis\/tree\/main\/src\/engine\">Merge engine API<\/a> and to prototype and specify various versions of sync under the Merge paradigm.<\/p>\n<p class=\"chakra-text css-gi02ar\">Proof-of-stake superceding proof-of-work is years in the making, and we&#8217;re just as excited as you to see it in action.
