Developed by the Federal Reserve Bank of Boston and MIT’s Digital Currency Initiative, Project Hamilton was a working prototype. Phase 1 delivered something no private payment network has ever offered: 1.7 million transactions per second, with settlement in under a second, no personal data stored on the ledger, no transaction history, no account numbers, and no surveillance architecture.”

I have a similar problem with “up and to the right”. “Up” I get but time moves inexorably to the right. There is no other option than “to the right” - the only variable in that equation is “up”! Why add an invariant as a qualifier?

The Chernobyl accident happened 40 years ago today. It is a fascinating case of large system breakdown that hastened the end of the Soviet Union. The Chernobyl series HBO did on it is required watching. amazon.com/Chernobyl-Season-…

My take on Bitcoin and quantum computing:
nehanarula.org/2026/04/03/bi…
tl;dr: I think the risk is high enough to warrant prioritizing designing, implementing, and evaluating post-quantum signature schemes and consensus upgrades in Bitcoin now.

"The fact that our internet is still run on advertising is kind of nuts. We think it can be run on money, on real value, as long as you make it fast and cheap enough."
