  • Here is a more detailed explanation of the exploit.

    The Pepaire-Bueno brothers exploited a bug in MEV-boost’s code that allowed them to preview the content of blocks before they were officially delivered to validators, according to the indictment.

    The brothers created 16 Ethereum validators and targeted three specific traders who operated MEV bots, the indictment said. They used bait transactions to figure out how those bots traded, lured the bots to one of their validators which was validating a new block and basically tricked these bots into proposing certain transactions.

    So hardly an attack on any core system of cryptocurrencies.







  • Yea, it’s pretty easy if you already have a server. All you need to do is run a docker container, and change the identity.sync.tokenserver.uri setting in about:config. On mobile you have to enable the debug mode by going to “Settings > About Firefox” and tapping the Firefox logo a few times, then go to the new “Sync Debug” settings entry.

    The container above only runs the sync-server though, you still have to log into a Mozilla account to use it. There is a replacement that includes the whole stack, but I haven’t tried that one yet.





  • If you have a monopoly and need to maximize profits then the question becomes: Why not?! You could extract more money this way, and it’s not like your users would go anywhere else at this point.

    That is why it’s so important to fight and break up monopolies, and to limit what these companies can do. Because they have no reason not to squeeze every penny they can get out of you!
