Very cool! I think this would go a long way towards demonstrating the power and robustness of the PoS mechanism.
It may or may not be obvious, but it seems this comes in two stages:
- Beacon chain does sufficiently well finalizing “ETH 1x data” for a given amount of time (how much time? 3 mos? 6 mos?)
- Beacon chain’s block finalizations are integrated somehow into consensus of ETH 1x chain (hard or soft fork? maybe in the mining software to reduce uncles? can we revert/reduce the effects if it doesn’t work?)
I think it’s important here to gradually incorporate this mechanism over time as it proves itself to work. We have to de-risk this combination enough in practice that it doesn’t get abused when vulnerabilities are discovered that we didn’t know about (“when” not “if”)
Also, is step 1. needed to process deposits?
Edit: I guess I’m saying I would like to be involved haha
