Flock Safety has issued a legal demand seeking the removal of a public map showing the locations of approximately 300,000 of its surveillance devices across the United States.

JUST IN: 🇺🇸 SEC Commissioner Hester Peirce calls to end mass KYC data collection, warning it puts crypto holders at risk of phishing and physical attacks. Pierce says the current KYC/AML system creates massive databases of sensitive information that can be hacked, leaked, or exploited. She's pushing for zero-knowledge proofs (ZK proofs) that could verify users meet regulatory requirements without exposing their personal information.

The first purpose-made hardware wallet to be a @safe signer! Check out this video where I show you how signing Safe txs is made secure, using local decoding and verification on the PQ1!

Every privacy protocol says "private." But the question is: private from whom? We just shipped a new feature on L2BEAT that answers that for every protocol we track, against 5 different adversaries.

Arithmetic-friendly hashes have long been one of the weakest pieces of prover cryptography. With ZisK v1.3.0, we removed Poseidon entirely and moved to BLAKE3. What surprised us is that we got the same performance — or even better. After many optimizations elsewhere in the prover, hashing had become one of the most time-consuming parts of proof generation. BLAKE3 is more than an order of magnitude faster, making this cost almost disappear and largely compensating for the increased complexity of the recursion circuit. Getting there required a lot of re-engineering: circuit sizes, prover scheduling, and architecture all had to be reconsidered around the new trade-offs that BLAKE3 gives us. The final result surprised even us. There is a lot of focus today on binary-field proving. Binary fields attack the hash-proving bottleneck from a different direction, but introduce different trade-offs when proving regular arithmetic. There is a huge amount of research happening here, and at ZisK we are following it very closely. I'm genuinely curious to see whether binary-field architectures will outperform what we can achieve with the current approach — and how long it will take. So I like to think of v1.3.0 as setting a new target. 🎯 To everyone working on binary fields — and to all of us trying to make provers faster: let's see if we can beat it :) And we still have a few optimizations in the basket.

Urgent security advisory for iOS users! Install the latest iOS update immediately. Security researchers report that financially motivated attackers are now using a complete, in-the-wild exploit chain that can quietly steal cryptocurrency private keys and mnemonic seed phrases from iPhones. The reported attack begins when a target is socially engineered into opening a malicious page in Safari. That page is said to abuse a memory-corruption flaw in WebKit / JavaScriptCore to gain arbitrary read/write access from JavaScript, then bypass Pointer Authentication Codes (PAC) to run native code, break out of the WebContent sandbox, and escalate to kernel/root privileges. With that access, attackers can pull data from the device Keychain and from local crypto wallet apps. The claimed impact range is iOS 13 through iOS 26.5; that range has not been independently confirmed in full. Until more is known, treat any unpatched device as potentially exposed and update as soon as a newer build is available. Also avoid untrusted links in Safari, especially if you keep wallet keys or seed phrases on the phone.

🔥所有用户请及时更新iOS 系统 DarkSword 攻击程序已经泄漏，其核心能力为：通过 HTTP 接口从 iOS 设备中提取取证级数据。 在实际攻击中，攻击者可结合社工或水坑攻击诱导用户中招，进而窃取 iPhone / iPad 内数据，并上传至攻击者控制的服务器。

Questioner: Would you back SBF [of FTX] again? Kevin O'Leary: "He was one of the most brilliant traders in the crypto Universe... the answer would be, yes."
