    Why Web3 Résumés Are Useless — And What Founders Actually Look At Instead

    Traditional résumés fail in Web3 hiring because they showcase experience and credentials rather than critical thinking, risk assessment, and debugging skills. Founders prioritize GitHub activity, test quality, PR communication, and reasoning ability over formatted documents. The article argues that candidates should focus on demonstrating their thought processes through code, tests, and architectural decisions rather than polishing résumés. It recommends founders evaluate candidates through GitHub repositories, revert tests, scenario-based questions, and proof of risk-aware thinking.

    The Industries Adopting Rust

    Rust is being rapidly adopted across multiple industries including security, backend infrastructure, embedded systems, and blockchain. Major companies like Microsoft, Google, AWS, and Cloudflare are using Rust for memory safety and performance benefits. The security industry particularly values Rust's compile-time safety guarantees, while cloud providers use it for critical infrastructure components. Embedded systems and robotics companies are adopting Rust for safety-critical applications, and the blockchain ecosystem has made Rust foundational for many protocols. Career opportunities exist across these sectors, with companies actively hiring Rust developers for both low-level systems work and surrounding infrastructure.

    The internet’s forgotten protocol…

    HTTP status code 402 (payment required) is being revived through X42, a new protocol by Coinbase that enables zero-fee micropayments for API requests. The protocol simplifies monetization by eliminating traditional payment processors' fees and complexity, requiring just one line of middleware code in Node.js. It supports instant, frictionless transactions using cryptocurrency and stablecoins, enabling machine-to-machine payments and AI agent economies. The implementation allows both user-facing wallet payments and programmatic transactions for automated systems.

    Blockchain File Storage!!!

    Decentralized file storage systems use distributed networks to store data securely instead of relying on centralized servers, utilizing blockchain or peer-to-peer technologies for data integrity and availability. IPFS, a P2P distributed file storage protocol, hashes content into Content Identifiers (CID) for retrieval. Various platforms like Filecoin, Arweave, Swarm, and Bluzelle offer decentralized storage solutions with unique pros and cons. Web3 storage solutions include on-chain, off-chain decentralized, and off-chain private storage.

    What are Merkle Trees and Proofs?

    Merkle trees are a data structure used to verify data presence efficiently within a blockchain without downloading the entire chain. They consist of hashed data organized in a tree-like structure to ensure data authenticity through hashing and comparing nodes. Merkle proofs allow users to verify the presence of specific data in the tree without accessing the whole structure, optimizing data storage and verification processes.
