What if There's a Bug No One Has Seen in Bitcoin?

Why is the world so sure that Bitcoin and blockchain is foolproof. What if there's a critical flaw that everyone has overlooked or not noticed and the whole system crashes down? Is it really impossible? Is Bitcoin a perfect machine or system?

As others pointed out, the strength of trust in Bitcoin is largely because it's open-source. Anyone who wants to check the code and understands the code can do it and report bugs if they are found. Bitcoin exists for a while and has a big community of people. Not to mention that there are of course plenty of people who'd want to exploit a bug in Bitcoin. So with that in mind, it's very unlikely that there is some sort of critical bug that nobody noticed before. There were times when serious bugs got reported, but they were caught early, so to speak, without being successfully exploited AFAIK.

What if there's a critical flaw that everyone has overlooked or not noticed and the whole system crashes down?

There are multiple software which can be used to run full node, so it's hard to imagine all of them have same overlooked flaw. Even if soemone manage to exploit bug on Bitcoin Core (most popular full node), i don't expect whole Bitcoin network crash or going down. I expect there'll some node and miner remain running, where i expect some congestion and many services going down for a while.

What if tomorrow a virus breaks out and kills all of humanity before we can discover a vaccine or a cure?

Anything is possible, is what I mean to say. But is it probable? No.

Same goes for Bitcoin. At this point, the probability of somebody finding a critical flaw in Bitcoin is almost non-existent. So there is no point in worrying about it.

already a bug
nodes bypass verifying every byte which lets arbitrary data to bloat a block
this bug has been known since 2016 even before it became active(2017)
many have noted the error and how it negatively could affect the bloockchain and negatively impact things like transaction counts per block and fee and congestion.. yet devs were sponsored to force it into being active as it helps the sponsors promote that bitcoiners should avoid using bitcoin and instead move to other networks to transact
