Fabric Cryptography wants to make modern cryptographic techniques like zero-knowledge proof (which lets you prove things without giving up exactly what you know) and fully homomorphic encryption (which enables you to work with encrypted data without decrypting it) ubiquitous. This, the co-founders argue, will ease what they see as a fundamental tension between trust and privacy in an age where companies gather increasing amounts of data about consumers, yet are also increasingly unable to safeguard this data. https://lnkd.in/exKpmdGZ

🚨 In the summer of 2023, we tested #ChatGPT’s vulnerability detection capabilities by analyzing 134 smart contracts 💻 The result: our very first 𝗖𝗵𝗮𝘁𝗚𝗣𝗧 𝗩𝘂𝗹𝗻𝗲𝗿𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗗𝗲𝘁𝗲𝗰𝘁𝗶𝗼𝗻 𝗥𝗲𝗽𝗼𝗿𝘁 🚀 Learn more ⬇️ https://lnkd.in/dVDWwYvV

New rumours exist that new research may allow attacker to solve any hard encryption problem. It means end of internet, crypto and more. Very hard to solve crypto networks may rise and whole internet may have to change in that case. Imagine running a software to be able to access a specific website for more and more encryption. For every website! That would be interesting. I think most fragile part is OpenAI should improve it's security systems for all. Their weights and model and explorations shouldn't be leaked. I hope they have good SecOps team. OpenAI board might not be wrong after all these issues btw.

The Incognito Darknet Market is extorting all its users, following the exit scam pulled by the admins 💸 Surprisingly, people shouldn't put their trust on darknet market makers when they say your messages are "auto-encrypted" and your money is safe. Brett Johnson, notorious reformed cybercriminal and builder of the precursor to contemporary darknet markets, makes a good point: "The Truth of Darknet Markets? ALL of them are Exit Scams. The only question is whether law enforcement can shut down the market and arrest its operators before the exit scam takes place." https://lnkd.in/dEqdmZen

Snake. Oil. Even if delivered exactly as promised, the computational load implied by any working homorphic cryptossystem remains infeasible. And you still have *all* the problems building a modern crypto system (key distribution, side channel attacks, malicious insider selling credentials, accidentally commiting keys to code, etc). Remember as Bruce Schneier said… “RSA’s homomorphism was known in the 1970s”…. Hasn’t been figured out. And even after being figured out, it’ll need to be proven safe. I do however have a proposal for the VC firms involved. It’ll be great…. https://lnkd.in/grdCek6G

Rapid innovation in foundational technologies like #quantumcomputing, #ai, and #cryptography is changing the fabric of global commerce. However, recent challenges with governance of OpenAI and the $4.3B U.S. Securities and Exchange Commission fines against Binance are clear signals that the private and public sectors need to work closer together to maximize social good and minimize systemic risks. I am very privileged to have the opportunity to collaborate with Don Hepburn and lean on his wealth of experience working with public sector agencies, to highlight the systemic risks presented by #quantumcomputing and signal a call to action for investment in #postquantumcryptography. Adoption @ scale without proper risk management is either impossible or creates systemic disruption. Neither leads to positive growth. Let's capture the opportunity to learn from past industry mistakes. The Messenger:

By the powers vested on me by nobody in particular, I hereby declare the first “official” Ethereum 2077 post live and available to read: https://lnkd.in/gEbJDV56 (I’ve been wanting to use Marc Andreessen's famous line for a long time). Read below for a more “serious” overview of the post: ERC-7512 (On-Chain Representation for Audits) is a proposal (by a team comprised of security professionals from Safe, Hats Finance, OtterSec, ChainSecurity, Ackee Blockchain Security, OpenZeppelin, and Omniscia) to standardize approaches to verify audits for Ethereum smart contracts *on-chain*. This is different from the status quo where you have to manually verify (off-chain) if a smart contract is audited or not by visiting the project’s website and looking for a link to the audit report (*if* one is available); and even if you do find the audit report, you need to trust that the code described in the audit report is the same code running on the blockchain (“DYOR” can feel like an extreme report for this reason). The authors of ERC-7512 want to change things up by asking auditors to create representations of audits that can be stored and verified on-chain—one of the few times “put X on the blockchain” has actually sounded like a good idea. Of course, the idea is a bit more complex, which is why I’ve written a comprehensive article that provides background information related to ERC-7512, explains the standard’s inner workings and value to the ecosystem, and discusses some of the limitations that need addressing before ERC-7512 can truly become the ultimate security solution its proponents want it to be.
