user2236: During the 2021 Summit Aggelos briefly mentions a future of Cardano which includes sidechains which will, among other things, enable integration with other blockchains.
Does anyone have in depth resources (eg: whitepapers, IOHK blog posts, etc) which elaborate on this idea so that I can learn more?

user1130: I would take a look at Hydra.
