Recently, someone asked me again whether cross-chain bridges are safe or not… To be honest, I’ve always considered them “the most likely point of failure.” Multi-signature sounds stable, but it’s really just about who holds the keys and how many people can agree to make a decision; oracles are more like “data feeders,” and once the data is skewed, no matter how smart the chain is, it will follow the skew.

So now I usually prefer to wait for several confirmations when crossing chains, even if it’s slower, at least to avoid those pitfalls of “looking back and seeing the transaction reorganized or the state mismatched.” Modularization and the DA layer narrative make developers excited, but users (including myself) sometimes look confused: the more things are broken down, the more cautious we need to be with bridges and data. There are many tutorials, but I prefer those that discuss failure cases and permission structures, so I can have a clear understanding, stand firm first, then move forward.
