Serenity/ETH 2.0 will introduce a PoS consensus mechanism, sharding etc and my understanding is that it will be a new chain running in parallel with the old one. How will this affect trading and funds management of ETH/ ERC20s on Nash?
I believe @localhuman is the best person to reply, but given Phase 0 and Phase 1 of the new system there is no needed changes. Phase 0 will see the implementation of a PoS chain called the Beacon chain but all contracts will stay in the PoW chain, than Phase 1 will add the shards validation but not yet move the computation. It appears to be a multiple years effort to move the chain.
