A little curiosity. A world of open source.
THE FIRST COLLECTIONKotoba is a security-first, declarative language and computing stack for AI agents that enforces capability-safe execution, post-quantum cryptography by default, content-addressed artifacts, and explicit authority boundaries to confine untrusted code.
SUM is an open-source tool for verifying AI text transformations with cryptographic receipts. It checks what changed, what was preserved, and what was lost when AI rewrites text, with cross-runtime Ed25519 signatures and offline verification.
Trahens is a research protocol for privacy-oriented rendezvous route discovery and control-plane management in decentralized, path-aware networks.
Bitcoin Core is the reference implementation of the Bitcoin protocol. It connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions, and optionally includes a wallet and graphical user interface.
TundraLibs is a suite of independent, cross-runtime TypeScript libraries compatible with Deno, Bun, Node.js, Cloudflare Workers, and browsers. It provides modular tools for databases (ORM, drivers), authentication, validation, logging, tracing, caching, and HTTP routing.
tc_rust is a pure-Rust cryptographic library ported from Bouncy Castle C# for learning purposes. It offers extensive block/stream ciphers, digests, and elliptic curve math, but remains unaudited and unstable.
Dart wrapper for OpenMLS implementing Messaging Layer Security (MLS) protocol for encrypted group messaging, with TreeKEM, encrypted storage, cross‑platform Flutter support, and experimental post‑quantum ciphersuites.
