Rust becomes clearer when you use it to solve systems problems. LowLevelCraft’s Rust track covers ownership, borrowing, unsafe Rust, FFI, custom allocators, and no_std. You build things like a linked list and allocator, then let the compiler show you where your design is wrong. Link: lowlevelcraft.com/tracks/lan…

Meet xPaywall - an open-source, self-hosted gateway for monetizing APIs via the x402 and MPP (Machine Payments Protocol) protocols. Add machine payments to an existing API without changing your code. Just point it to your API endpoints, configure routes and prices - and your API is ready to accept payment for every request. How it works: - add your upstream API, routes, and price - an AI agent sends a request to xPaywall - xPaywall responds with HTTP 402 Payment Required - the agent pays for the request via x402 or MPP - xPaywall verifies the payment and proxies the request to the upstream API Benefits: - no changes to your API server code - xPaywall is installed separately - request, revenue, and usage analytics - opensource - full control and self-hosted deployment - AI agents can discover your API through Bazaar Extension, the x402 discovery layer xPaywall consists of two parts: - xgateway - a lightweight proxy that can be used standalone and configured through YAML. - xPaywall - a complete self-hosted stack: admin panel, routes, pricing, analytics, and logging. Today, xPaywall supports: - x402 - exact scheme - MPP - charge scheme (Tempo only for now) Next on the roadmap are other x402 and MPP schemes, plus APP (Agent Payment Protocol by OKX). We'd love your feedback, issues, stars, and contributions.

we're absolutely against the ENS Foundation capturing the treasury ($20M in USD + ETH), and absolutely for experiments like @donnoh_eth gwei.domains/ that burns ETH. better to burn the money than hand it to the people who later try to capture it.. so we invite every cp0x reader and community member to mint a free subdomain like .cp0x.gwei at gwei.cp0x.com a shame that .eth is already captured. the problem was never the DAOs. it's who sits above them!
announcing gwei.domains, a ENS alternative forked from @z0r0zzz's wei(.)domains to be ownerless and unruggable. funds used to buy and renew domains are burned permanently to remain neutral. domains start from <$1 and .id.gwei domains are free. try it out!

Mithril's validator arc is in motion. Our lean verifying node is still live and being polished, and we've begun charting the path to another validator client for Alpenglow. Thank you @cavemanloverboy for forging a key piece that has Mithril building blocks on Alpenglow testnet

I'm starting my own rust tutorial series. This is a series for anyone who looked at some rust code and felt scared by the syntax. This very first episode will get you started with some basics. But the goal is to gradually build up and go to the complex topics. If you're a complete beginner, then definitely give my series a try. Full video link below 👇

🦀 Rust: memory usage. Option isn’t cheap just because it’s None. The parent struct still reserves space for BigStruct.
 A useful tradeoff is: • Option → faster access, larger parent
• Option> → smaller parent, heap allocation
