ChainCatcher message, Bitcoin Core developer Luke Dashjr posted on X: "Seven years ago today, the Bitcoin community launched Segregated Witness (Segwit), although Bitcoin Core refused to allow anyone other than miners to make decisions.Today, we are facing a similar situation while updating the spam filter. Sadly, the community is largely too complacent------or brainwashed------to take action.Bitcoin is not about blindly trusting a centralized maintenance team------that’s what fiat currency is for. Decentralization requires active users who need to make decisions for themselves."

ChainCatcher news, SMG research director Max Resnick posted on social media: "MEV is fundamentally about control. Proposers can control which transactions are included in a block and the order in which they are included. In other words, MEV is about censorship and reordering. The good news is that solving this problem is possible.The first step is to address censorship resistance by establishing multiple parallel proposers; the second step is to tackle the reordering issue. Once there is a multi-proposer architecture, proposers can reach consensus on a set of unordered transactions, and the execution layer is responsible for sorting them using deterministic rules."In response, Vitalik Buterin stated: "Doesn't this lead to people flooding the chain with transactions to collect MEV, thereby maximizing their chances of being first? So you would still get 'MEV auctions', but with more negative externalities at the protocol level.We saw this during the ICO era in 2017 when some projects tried to ban transactions with gas fees above 50, resulting in a lot of on-chain spam."

I'm sure all parties involved are paying the network bills."

ChainCatcher news, Bitcoin Core developer Luke Dashjr stated on X that "Inscriptions" are exploiting a vulnerability in the Bitcoin Core client to send spam to the blockchain. Since 2013, Bitcoin Core has allowed users to set an additional data size limit ('-datacarriersize') when forwarding or mining transactions. Inscriptions bypass this limit by disguising their data as program code.Luke Dashjr stated, "This vulnerability was recently fixed in Bitcoin Knots v25.1. Due to severe disruptions in my workflow at the end of last year (v24 was completely skipped), the fix took longer than usual. The upcoming v26 version of Bitcoin Core still has the vulnerability. I can only hope it will be finally fixed before next year's v27."
