For anyone curious about elliptic curves, i wrote a simple thread back in 2023 exploring the K1 vs R1 problem through RIP-7212 (ex EIP-7212 proposal)
HOLY SHIT. For crypto, this is one of the most insane posts of the year, but I'm guessing most people don't understand it. Let me explain... Bitcoin's accounts, and subsequently Ethereum's (and therefore every other EVM chain's), are built on a specific elliptic curve called secp256k1. secp256k1 is a different elliptic curve from the one used across nearly every modern hardware device, including iPhones. Modern devices mostly use a different curve called secp256r1, which is usually referred to as P-256 - one of the curves investigated in the article. This mismatch has made it sooo difficult in the past to integrate crypto accounts natively into the security systems of modern hardware. For example, Apple's Secure Enclave natively supports P-256, not secp256k1. This has prevented crypto accounts from being able to use the same hardware protection as things like Apple Pay. Same goes for the web with passkeys - WebAuthn uses P-256 signatures, which means Ethereum accounts using secp256k1 can't use them natively either. But why did Satoshi do this? The main theory for choosing secp256k1 was distrust of the P-256 curve - i.e. he thought there was an NSA backdoor. A "backdoor" here basically means a secret, intentional weakness in the curve that would allow the NSA to exploit it and access private keys. This was because P-256 was created with involvement from the NSA... And the NSA provided a mysterious "seed" used to generate one of the curve's parameters without explaining where that seed came from. This eventually transformed into a ~25-year-old mystery with a 5-figure reward for finding where this seed came from. Claude figured it out in less than 30 mins. And the best part is its internal thinking was: "Hmm wait... is it suspicious that such an obvious thing wasnโ€™t discovered in 25 years?" The solution was stupidly simple - just the time the curve was created, put into a specific random number generator function. This doesn't 100% prove there's no backdoor yet, but it provides strong evidence that this seed wasn't secretly engineered by the NSA. And Claude did this with "just a simple prompt" in under 30 minutes.

Devcon has changed some people's lives, sometimes all it takes is being in the right place at the right time. Thanks for the interview @EFDevcon
Different perspectives. Different backgrounds. One community. We asked the Ethereum community what makes Devcon special, and why Mumbai is the place to be this November. ๐Ÿ‡ฎ๐Ÿ‡ณ Here's what they had to say.

๐ŸŽ“ AI Engineering Bootcamp completed at @dev3pack! ๐Ÿš€ 3 intensive weeks focused on Harness Engineering: building the deterministic Python infrastructure around an LLM to ensure safety, reliability, and stability in production. The core takeaway: an AI system shouldn't just know how to execute - it must have strict boundaries to refuse execution (Refusals) when conditions aren't 100% safe. ๐Ÿ› ๏ธ What I built and validated via PRs: ๐Ÿ”น Structured Outputs & Bounded Tools: Strict schema parsing and read-only tools to prevent tracebacks from provider failures or invalid inputs. ๐Ÿ”น Deterministic Loops & State Graphs: Call budget limits, repeated call trapping, and state machines with explicit, guarded transitions. ๐Ÿ”น Evaluation & Grounding: Precision/recall measurement against labeled datasets, regression analysis, and trace-based failure classification. ๐Ÿ”น MCP Architecture & Security: Pre-execution evaluation of external tools, SSRF network fetch guards, and strict per-user memory isolation. ๐Ÿ”น Deployment & Operations: Request boundary configuration and automated smoke testing to detect flawed deployments early. Grateful to the @us3Gecko @dev3pack @ernanibritto @0xLeti team for such a high-caliber technical program. Ready for the next system architecture challenges! ๐Ÿค– #AIEngineering #AIAgents #MCP #SoftwareEngineering #Python

For a full week I kept building Vespi, the kernel of Lore's operating system for working with AI. The project I made for @BuildOnStellar Find Your Way and Meridian hackatons. It lets you build complex apps with AI, without knowing the hard parts, and this is what it is now ๐Ÿงต

1 year ago in Chile ๐Ÿ‡จ๐Ÿ‡ฑ, I won my 1st Web3 award in the Ideathon @TellusCoop and @BuildOnStellar ๐Ÿ’ก๐Ÿ†. That achievement set off opportunities I never imagined. @TellusCoop awarded me a scholarship to HackMeridian in Brazil ๐Ÿ‡ง๐Ÿ‡ท, at the Copacabana Palace. Then came residencies and scholarships in Argentina with @dev3pack and @Polkadotsub0 ๐Ÿ‡ฆ๐Ÿ‡ท, which motivated me to perfect my English in Malta ๐Ÿ‡ฒ๐Ÿ‡น. Today I am in Switzerland ๐Ÿ‡จ๐Ÿ‡ญ, packing my bags for Germany ๐Ÿ‡ฉ๐Ÿ‡ชโœˆ๏ธ. @TellusCoop was the catalyst that completely changed me in 1 year. So, if you are looking for an opportunity to learn, build, or connect, @TellusCoop opened registrations for its new hackathon: Find Your Way ๐Ÿš€. P.S. You've got until October 5th to submit your MVP - don't overthink it, Just give it a try! โค๏ธโณ
