Hm, I thought SAB was disabled in WebKit. Grok over on Twitter told me it was disabled in 2018 as a mitigation against SPECTRE. See also: x.com/TomZarebczan...

prompt: develop a new programming language that is optimised for AIs to read and to write, including a highly efficient implementation for all major machine architectures

P.S. When and if Apple adds support for `SharedArrayBuffer`, then this implementation of BLAKE3 will go multiple *times* faster than it already does on iPhone, by taking advantage of multithreading.

I think β€œNothing 3a Pro” is a pretty great product name for a phone.

Builders take note. If you’re building a local-first app, decentralized web app, or something else where you want cryptographic protections for the user, and wasm compatibility, check this out!

BLAKE3 vs SHA-256 Browser Benchmark

New! Thanks to lamb356, here’s BLAKE3 in portable WASM. It runs anywhere wasm does (which means all web browsers for starters), and in some cases it runs even *faster* than native, hardware-accelerated SHA256. Try it: lamb356.github.io/blake3-wasm/

zooko.github.io/zcash-networ... Try it! Try scrolling and zooming. Try toggling the "Supply", "Issuance / Day", and "Annual %" buttons at the bottom.

Okay, this is pretty good so far! Still no ZIP 234 (or other possible ZEC-recycling protocols), and it is bad on mobile, but, it's pretty good! Please try it out (on desktop) and tell me what you think! I'm running out of steam for tonight. zooko.github.io/zcash-networ...

P.S. Please! Participate in this shielded coinvote, and vote in favor of Explicit Feesβ€”ZIP-2002β€”because it can help prevent wallet bugs that cause wallets to accidentally send their user's money to a miner.

(ZSAs are extending their lead as the most controversial topic, Explicit Fees is taking the lead as the least controversial topic πŸ˜†)

omg even more permissionless, shielded coinvotes!? This poll is going to be so great for Zcash as a demonstration of the size and diversity of the Zcash community. sauce: forum.zcashcommunity.com/t/coinholder...

The more people and the more coins vote in this poll, the better for Zcash.
