I hadn't joined at that time. I saw the need to ask questions so I could catch up with many things that I have missed so far. I guess this might be the last question based on this matter.
Then you may like to see some history about spam attacks as well. I tried to list some cases in this topic a couple of years ago:
https://bitcointalk.org/index.php?topic=1776143.0We've been dealing with different types of spam attacks for a long time. I consider Ordinals to be the continuation of the same attacked called "stress test" back in 2015 but much more severe as it get regular users to participate in the attack without knowing they are actually performing an attack.
All the prolonged and major mempool congestions so far have been due to spam attacks.
Not sure if anything can be done to handle Ordinals, Runes and BRC_20 token at the moment as they are already active.
This should have been nipped in the bud. At its very early stages when the scam market hadn't grown, introduction of standard rules could have had a high chance of preventing the attack from growing. There weren't that many txs to reject.
As time passes the chances of making them non-standard to make propagation of such spam txs hard is not looking good.
I believe the best (cheapest) solution at this point is to create some sort of side-chain that carries the name Bitcoin (so the scammers can still get their junk hyped) and encourage newbies who buy this junk to migrate there.
1. Is this exploit done for selfish or general benefits?
2. Do you think Ordinals, Runes and BRC-20 will become a massive problem in the present and future?
1. It's hard to know the reasons for this with certainty. But it looks suspicious enough, specially the early stages of storing massive data in chain. It was done in the dumbest way possible and it is hard to accept it from someone who could read the code, understand the scripts and find the exploit and yet not be able to come up with a less buggy and more efficient way of exploiting it!
2. I think they are as big a problem as they can be. There could be other consequences in the future like government bans because some idiot stored something illegal on chain...
