After a deeper read on Liquid implementation and Cashu and listening to #[3]​ podcast with Adam Back, the whole Whirlpool debate started looking entirely artificial and out of place. Liquid still has to solve the „peg out“ problem imho as it is very suboptimal. But once they’ve solved it, it is gonna be a killer feature.

What is the "peg-out problem"?

It is the process of „burning“ L-BTC held by on Liquid sidechain to release the equal amount of mainchain BTC. Currently this can be only be done by a Liquid federation member, which implies some trust in the federation.

You can do a swap instead of pegging out

True. For you as a single use the problem is not that big: there are good swap services. But globally the problem remains unsolved.

It will never have the same trustless of layer 1, it’s the trade off for lower fees and privacy.

It won’t. But it can be improved either by reforming the federation or by allowing Liquid nodes to peg out (same way you can force close a LN channel on your node).

I see. So it's not a technical problem, more of a design tradeoff that's not to your liking.

Correct. More of a conceptual & design problem that can be resolved in practice, while the whole Liquid thing will certainly always be a trade-off.

Is this the last podcast with Jack Mallers?

Thanks!!!

Much to my embarrassment, I didn’t know well enough who Adam Back actually is, his background and that he holds a PhD in computer science🤦‍♂️🤦‍♂️🤦‍♂️ Now I know.

He is cited in the white paper for Hashcash

And one of the original cypherpunks...inventor of hashcash, the proof of work...and a possible candidate or collaborator of Satoshi....

And also the guy who printed a perl implementation of a cryptographic algorithm on a T-shirt and crossed the borders of the US, demonstrating that categorizing algorithms as munitions was against 1st amendmend. Clinton reclassified cryptography a few years later.
