The story so far: In the beginning the Web Server was created. This has made a lot of people very angry and been widely regarded as a bad move.

@itsnebulalol They misread 256 bit as 0-256,
I bet

[Shielded Labs @ShieldedLabs]

Big milestone for Shielded Labs: the activation height for NU7 is being set today! The upgrade includes our first major mainnet deployment: the Network Sustainability Mechanism (NSM).

Like Bitcoin, Zcash faces a long-term challenge: how to sustain network security as block rewards decline. The NSM helps address that while preserving the 21 million coin cap.

ZIP-235 removes 60% of transaction fees from circulation, allowing that ZEC to be reissued as future block rewards. ZIP-237 starts that recycling around February 2031.

At current fee levels, that’s only about 210 ZEC per year. This is a modest first step, but we’re optimistic about how new use cases for the NSM could evolve over time and contribute to Zcash’s long-term security.

Can someone reverse engineer TouchDesigner please? 😭😭

[Joel Valenzuela @TheDesertLynx]

Had the great pleasure of chatting with @aescobar0g of @rhea_finance.

Finally it seems like we have a good native DeFi stack for cryptocurrencies, like privacy coins, that don't yet have it in their own ecosystems.

Yet another killer NEAR Intents use case.

@ShieldedLabs @Zcash Protocol Study Session Notes, Session 9 (Part 1); Hash Functions:

@shieldedmark walked us through the small zoo of hash functions behind every shielded transaction: which one runs where, and why each was chosen.

@feministPLT also helped to explained some hard parts

We covered:

1. The Hash Function Zoo: the SHA-256 & BLAKE2 families
2. Merkle Tree Hashes & Sapling's Positional Randomness
3. Viewing Keys & Quantum Recoverability (CRH^ivk, ZIP-2005)
4. Group Hashes: Getting Randomness Into a Group

Section 5.4 is big, so the session was split into parts. This is Part 1.

[🛡️ @shieldedmark]

Protocol Study #9.2: Hashes, Curves, and PRFs (Part 2) starting in roughly 24 hours!
