I read about Polkadot, Ion, Komodo, POA and many others projects. But my question is: are there any project to provide interoperability between public Ethereum and other blockchain/DLTs already WORKING IN PRODUCTION? If not, what project do you think will solve that first?
By interoperability I mean atomic swaps, information exchange, distributed transactions etc. It can be with permissioned Ethereum or with a different DLT (hyperledger, EOS etc).
