Today marks a decisive moment in my life.
I successfully defended my Master’s thesis.
@UZH_en
This closes a cycle that began the day my father died in 2015, and marks the beginning of a new chapter.
I dedicate this moment to him. 🛡️

Here's everything Zcash wallet implementers need to know for NU7:
- The biggest thing is that v4 transactions will be disallowed, which deprecates the Sprout shielded pool. If your wallet still uses them at all: be advised.
- Block times are speeding up to 25s per block. You shouldn't need to worry about this, as any concerns from that change will be mitigated by the full nodes and indexers.
- The 60% removal of fees from issuance is shipping as part of the Network Sustainability Mechanism (NSM). You do NOT need to do this manually as, similarly, the full node consensus layers take care of this for you.
- Due to increased chain activity and anticipated further increases, we STRONGLY recommend you implement the following fees features:
1) Switch to using the `getstandardfee` RPC call to get the marginal fee. There has been some drift between Zakura and Zebra when it comes to fees, and this will ensure that you don't need to pay attention to any of this nor update constants. Now is the time to do this.
2) Implement a option to pay more for inclusion. We recommend 10x the standard fee you receive from `getstandardfee`

I don't think people understand how cool it is that Zcash is open to cutting-edge techniques like Formal Verification and Private Information Retrieval. It makes being part of the ecosystem feel fresh and exciting in ways that the AI age has degraded otherwise.

One challenge that persisted in crypto is that almost intentional way of communicating complexity publicly.
This among other things what leads to proliferation of scams as it’s easy for non experts to get lost in all the jargon and hard to distinguish what is real innovation.
Same is happening now - cryptographers sharing the possible risks in current schemes publicly without either explaining that other solutions are already in the works or giving historic context that cryptography has been evolving over past 50 years and has advanced every time to get ahead of found issues.
Leaders in the space must uplevel comms to explain things simpler and bring pragmatic solutions to market.
I think Justin Drake's latest alarmism/vagueposting is going to do a ton of damage in multiple ways. It's basically a huge self-own for their own advocacy work on quantum stuff.
Threats from quantum/AI are real, and teams throughout this industry are making considered decisions about how to respond to those risks in a practical way, and to help their users navigate the uncertainty.
Some of those teams have really good cryptographers with an excellent grasp on the decisions they can make, others have to take their cues from trusted experts. There are so many dimensions to optimize along! And due to the complexity involved, it's almost impossible to explain this stuff to non-cryptographers.
Experts have to be cognizant of all this, and of their responsibility to be levelheaded.
After the fog clears up and people learn from their cryptographer friends what is actually going on, they're going to discover this was (at best) an unintentional marketing stunt and a lot of trust will be lost. And nobody will really know what to do...
This is a shame, because they are directionally correct. It actually meant something when they sounded the alarm before. They've just gradually descended into unhinged predictions without feedback to discourage it.
Can anyone, I mean seriously anyone, justify this debacle? It permanently colors all the legitimate concerns/predictions about classical crypto going forward. By their own admission, there was no new information that drove this. I think Justin Drake should explain how he thought this was the right approach, even if he genuinely believed what he was saying.
Baffling.

Here's our plan for quantum-safe, unlinkable, rotating taddrs. Possible with Zcash, today.
While others are worrying about the viability of rotating transparent addresses, we're already solving linkability.

Announcing hashsma.sh! 𝟘 𝟙 ❒ 🔨
Strengthen cryptography with AI.
Cryptography—both current and post-quantum cryptography—depends on hashes. SHA-256? SHA-3? BLAKE3? Nobody knows if they are secure. We're going to find out!
Come help accelerate scientific research!
HashSmash is an open science-acceleration project in collaboration with @yukonresearch, @eigenlabs, @projecteleven, and @ShieldedLabs.
Yes! For wallets, under standard features, you can drop in swap to github.com/zakura-core/walle…
You’ll get way faster proving and trial decryption. If you run lwd nodes, you’ll get way faster queries

Earlier today, NEAR Intents was exploited for $3.8m. SHIELD, the AI security layer on Intents, detected outlier behavior and Intents were temporarily paused. All of the affected users will be compensated in full.
The attacker exploited a bug in the Omni deposit/withdrawal interaction with the NEAR Intents smart contract isolated to USDT on BSC. The Intents team quickly identified the exact vulnerability and it was fixed within an hour of detection. NEAR Intents and near.com are already back online, except for a few affected chains on Intents. The core NEAR Protocol, NEAR token, and other applications on NEAR were not affected.
NEAR Intents now processes over $4B a month in trading and payments volume, serving as the industry’s connector across chains and ecosystems. At this scale, we have to hold ourselves to a higher security standard. This was the first major exploit on Intents and we will apply all learnings from this incident as part of a full retro and postmortem.
The crypto space is entering a new era of far more sophisticated cyber attacks. Recently, we have seen BitGet, Metamask, Lido all being targeted by criminals equipped with AI systems that are continuously trying to hack all infrastructure. As a space, we need to be far more vigilant and raise the bar on both onchain contract standards and offchain monitoring and proactive prevention.
This includes incorporating formal verification, a key tool for preventing a large class of vulnerabilities. The NEAR ecosystem is already working on a formal verification system for NEAR contracts and will shortly implement it as part of the release process, alongside other security measures that will come out of the postmortem.
Being more proactive against criminal activity is a critical step to ensure the growth and legitimacy of crypto. It’s time to join forces and work together to use all tools at our disposal to detect and prevent malicious activity. SHIELD is our approach to monitoring and AI-based outlier detection. We welcome new SHIELD partners to work with us to share information faster and get better at detecting and containing criminals and exploits across web3.
Earlier today NEAR Intents services were stopped after a security incident was detected. The incident was caused by a bug in the Omni deposit and withdrawal infrastructure interaction with NEAR Intents smart contract.
The preliminary report indicates the total loss of approximately $3.8M. These funds will be compensated in full.
The contract-side vulnerability has been patched. The operations of the NEAR Intents and near(.)com are expected to resume within 1h.
Deposits and withdrawals on the following networks will remain unavailable for an additional ~12 hours while fixes to the Omni infrastructure are completed: BSC, Polygon, TON, Optimism, Avalanche, Stellar, Monad, LayerX, Adi, Scroll and Plasma.
In case users hold any assets from these chains inside NEAR Intents (for example, in HOT wallet or on near(.)com), they will be able to swap them into other assets once NEAR Intents is back up (in ~1h).
The incident has been reported to law enforcement, and we are working with security and blockchain analytics partners to trace the funds and pursue recovery. A detailed report will be shared publicly in the following days.

Zcash is winning because zebras are fueled by conviction.
The strongest communities are not held together by profit, but by principle.
Noir delivers because conviction builds.
Wealth follows value.
Value attracts builders.
