@vbuterin hi, i know a lot of time has elapsed

i would like to know if any progress has been made in this regard ?

is there a bridge between PoS & PoW ethereum chains ?

is there a way to burn / lock tokens on the PoW chain (ETHW) and mint an equal amount of nodes on the ETH (latest ethereum) chain ?
