All technology must be able to defend itself against attack.
The accelerating sophistication of cyberattacks raises the threshold that every software system must clear simply to remain viable.
This has always been true, but AI is compressing timelines.
Even quantum, a distinct attack vector from AI-enabled exploits, is nonetheless being accelerated by AI.
Preserving capital through this accelerating shift in offensive capabilities means holding assets capable of withstanding a step-change in the hardware and software capabilities that will inevitably be pointed against them.
Zcash is built specifically for this environment.
Zcash is Bitcoin that adapts.
Zcash's privacy protects its users from all-knowing AGI deployed by thieves, attackers, and governments.
It is furthest ahead on post-quantum; $ZEC stored in the privacy pool is already safe from Q-Day.
Even the Zcash PoW long term security budget problem is accounted for.
Zcash's product is safety for your capital.
The more powerful the tools of attack and surveillance become, the more valuable privacy and security become.
I expect demand for safety of capital to be significantly higher in the future.

I’m not sure we want a small group of people with a particular set of strongly held moral convictions to surveil and control what is becoming our thought space
We’ve trained Claude to flag potential misuse in conversations, a technique we call self-assessment. Right after it responds, Claude gives a preliminary safety assessment of the conversation.
Since we began using self-assessment in June, it has surfaced misuse that our other safeguards weren’t designed to catch.
Because Claude has already read the conversation, self-assessment is very efficient. And unlike classifiers, which target a discrete set of harms, it draws on Claude’s own judgment, so it gets more accurate as our models improve.

Great to see new polling from @fund_defi reaffirm @DCGco findings from earlier this year. Financial privacy and control over personal data are priorities for Americans.
74% value financial privacy, 80% want more control over their data, and 62% prefer privacy in financial transactions.
The DEF team is excited to unveil new national, longitudinal research by @Ipsos on KnowledgePanel, digging into Americans' perspectives on the current state & future of finance, including their thoughts on frontier technologies.

Grayscale Says Zcash's 20% Developer Funding Has Fueled a Decade of Innovation
Grayscale, a leading digital asset manager, highlighted Zcash's (ZEC) continued innovation ahead of its 10th anniversary on October 28, attributing part of its progress to the allocation of 20% of block rewards to developer funding. The privacy-focused cryptocurrency has evolved through multiple shielded pools, from Sprout and Sapling to Orchard and the 2026 Ironwood upgrade, which introduced quantum-recoverable addresses and formal verification to address security vulnerabilities.

Zcash $ZEC is leading financial privacy by innovation.
Zcash funds its own development. 80% of mining rewards go to miners, with 20% flowing into R&D through the Dev Fund, keeping the ecosystem free from venture capital. That funding recently went toward Ironwood, a new pool with advanced privacy features.
