🧠 Alibi – Embedded Cryptographic Ledger Core

Alibi is a Rust-powered, no-std-compatible cryptographic engine and tamper-proof ledger designed for local proof generation on any device — embedded, mobile, WASM, or desktop.

🛡️ Zero-trust. Self-contained. Audit-friendly. Built for real-world integrity.

🧩 What is Alibi?

Alibi provides a minimal yet powerful set of cryptographic primitives and a verifiable append-only ledger to enable local proofs of authenticity, integrity, and time — without relying on third-party infrastructure.

Whether you're building a secure logger, a decentralized audit system, or a verifiable CI/CD chain, Alibi runs independently, cryptographically-secure, and deterministic.

✨ Core Features

🔐 Cryptography
