Recently, everyone has been talking about the upgrade/maintenance of a certain mainstream public chain, guessing whether the ecosystem needs to migrate, honestly, don't rush to pick a side first, just check if the project's "credibility" has a solid foundation. Beginners can also take a quick look: don't just look at the stars on GitHub, check if the recent commits are continuous, and whether it's just one or two people working alone; don't treat audit reports as a talisman, focus on whether issues have been fixed, whether the fixes are complete, and don't just pass it off with "accepted risks"; multi-signature upgrades are even more critical, how many signatures, who is signing, can the signers be replaced, is there a time lock... these are the key factors that determine whether you can sleep peacefully knowing the upgrade won't reset everything overnight. To make an analogy, it's like renting a shared apartment: no matter how beautiful the contract (audit) is, if the keys (multi-signature) are all in one person's hands, can you really sleep well? Anyway, for me, when it comes to perpetual projects, I only look at these things—discipline outweighs faith, and being stubborn isn't as good as staying cool-headed.
