Recently, there's been talk about sharding and parallelism again, and it all sounds quite lively, but I usually just take a quick look first: once the money comes in, how does it go out? The bridges that cross back and forth, message passing, admin permissions—if any link malfunctions, it can really turn into a "paper asset." L2 has been comparing TPS, fees, ecosystem subsidies, and the mouth-warring has been intense, but I've become more concerned with: in case of congestion, downtime, or upgrade failures, do you have a clear exit path, or at least know where your funds are stuck? For me, security is about patching and small fixes: minimal permissions, delayed activation, multi-signature not just for show, no backdoors in critical functions... Anyway, don’t let the narrative carry you away.
