We're about to run the private Ethereum PoA chain based on Clique and thinking how would we support it for ages. Hence we're wondering:
- Whether Ethereum 2.0 updates (London, etc) are even applicable to PoA chain? Ethereum 2.0 is a migration to PoS consensus algorithm, which seems odd as we already have PoA in the chain.
- Will this chain receive updates to be conformant with the Ethereum mainnet chain?
- When sharding is introduced in the Ethereum mainnet chain, how PoA/Clique chain will pick it up? Is it possible to answer this question now or the solution is yet to be developed?
Thank you for any help.
