I succumb to horror & nausea as the holodisplay shows the last shreds of human civilization obliterated by the computronium shockwave. In 43 minutes, it will reach me on the station. It’s over.

“Could we have done anything about it?” I weep.

“There were… signs,” the AI admits.

Are blockchains decentralized? From Trail of Bits some security analysis on blockchains. They find some novel attacks and do a lot of other research. In particular they point out how network control can be used (by dropping packets) to lower the hash rate needed for a 51% attack. Given that 55% of Bitcoin nodes are only available via Tor, and 20% of Bitcoin nodes run old software…

I would just say, I think whatever attacks they found can’t be that trivial to implement because they didn’t implement them and steal billions of dollars of crypto. Just as a Proof of Concept. Of course. Bug bounty?
