I remember back in 2017, while people were fighting over block size, there were some "promises" or "suggestions" to increase the block size every few years, do you guys know what happened to that? And when would be the "natural" time to increase the block size by 1MB? Wasn't there a debate or analysis that we'd need to increase block size 1MB every 4 years or so?
I feel like unfortunately the community gets caught up into so much nonsense that they forget certain things such as scaling. But at the same time we are in no immediate rush to increase the capacity because statistics tell us that the current block space is enough to handle the current existing use case. That is if we ignore the malicious spam attack.
In any case no fixed or preplanned increase (like 1 MB every 4 years) can work because we can not predict how the adoption is going to increase to create that need.
Ordinal transactions can be indistinguishable if there is enough demand; what you are suggesting is to censor this type of tx, assuming that will be enough, which seems to me like a terrible mistake.
Ordinals (and any other similar) attack is easily distinguished since they contain "dead weight" or data that is not used in the verification process. The arbitrary data they are injecting into the chain. They can easily be rejected and it is never and has never been censorship to prevent protocol exploits.
Yes, you just need to look for certain pattern on witness data. For example, Ordinals documentation mention string "ord" always used.
It is easier than that, you just have to look for a branch that can never execute. That is the OP_FALSE OP_IF usage.
