What's the status of sidechain theory?


I only read the “Non-Interactive Proofs of Proofs of Work” paper, which is brilliant, but there are at least these pending problems:
1、What about Proofs of Proof of Stake?
2、How to prevent people generate funds on different chains using the same proof of fund burning?
Are these still open questions?


There are huge strides to be made in side chains and other related concepts like sharding. I have ideas, but, I’m a wage slave with lots of personal responsibilities, and my research has fallen by the wayside : (


Yeah they haven’t published their research on this yet. I think Charles may have published a screenshot of the abstract or something on twitter. Really interested to read about this too.


This is only tangentially related but may satisfy you while you wait for a better answer
