Looks like they do this randomly for random reasons?

Unlike the train and tracks, this #manhattan approach does not get old.

If we go this route, any output descriptor with an elliptic curve public key becomes toxic waste. So you'd probably want to design a BIP32 alternative with post-quantum xpub / xpriv values. The toxic leafs would be encrypted and only decrypted for the actual wallet that needs it. #mitbitcoinexpo

Some wonderful brutalist architecture in #Boston

GM #Boston Also got a pretty good view of Greenland on the way up.

Dutch bureaucrats trying to come with a "solution" for startup equity holders in the upcoming unrealized gains tax system. A bureaucrat is going to decide if it's sufficiently innovative and if the innovation is scalable. Totally unclear if foreign startups can apply for this for Dutch employees. And what if they don't, or it after years of legal procedings the application is denied? Then the employee is just fucked and has to pay 36% of the paper gains the moment a funding round bumps the completely illiquid stock price. And will not get it back if it subsequently drops to zero. https://www.bnr.nl/nieuws/ondernemen-werk/10597781/nieuwe-definitie-startup-moet-box-3-probleem-oplossen-pas-betalen-bij-verkoop-aandeel

Yet another npm supply chain attack, though of course this can happen elsewhere. It was detected quite quickly. Seems to be aimed at developers, of which there are a lot more now thanks to LLMs.

So far I only read section "VIII. Dormant Assets" of the Google quantum whitepaper. Although I wish they used a two column layout, it's an interesting analysis. The National Security Response might actually be the easiest path, and there's nothing we can do about it. But it does require a president with diamond hands. They could issue an executive order, stating the United States shall be the first country to build a quantum computer, as publicly demonstrated by burning any coin that hasn't moved yet. By the time lawyers get to object, the transactions are already confirmed. The OP_RETURN statement would read: "EO 21400: fork your bitcoin if you want fork"
