What constitutes a true Bitcoin L2? Before discussing returns, security guarantees must be concrete and verifiable. A genuine Bitcoin L2 must at least meet these conditions:

First, the final state settlement must occur on the Bitcoin chain. This means that any disputes should be arbitrated and resolved by Bitcoin miners, rather than relying on MPC multi-signature or other centralized verification mechanisms.

The core of this requirement is that the security of the L2 must inherit the security of the Bitcoin mainnet. Only then can it be considered a true Bitcoin scaling solution, rather than a sidechain masquerading as an L2. Many projects claim to be L2, but in reality lack this on-chain finality guarantee, which fundamentally undermines the integrity of their security model.

Honestly, a bunch of projects are pretending to be L2 to raise funds, but very few actually dare to put settlement on the chain.

Honestly, there are so many projects claiming to be L2 nowadays that it's ridiculous. Most of them are just pseudo-L2s. If the finality isn't on-chain, don't talk about security—there's nothing wrong with that statement.

That's right, there are so many projects claiming to be L2 now, but only a few are truly reliable. You hit the nail on the head. The MPC multi-signature setup just doesn't work; only on-chain finality can really make us feel secure. Most people only look at the returns and don't care about security at all. It's hilarious.
