Listed in TeleAI-UAGI/Awesome-Agent-Memory (Emerging projects) after a maintainer audit of the claims against the code.
Now in the official MCP Registry: io.github.eddyflores100-lang/alethech — the read-only alethech-mcp bridge, discoverable by any registry-aware MCP client.
If alethech is useful to you, a ★ star is how other people — and their agents — find it.
From Greek ἀλήθεια (aletheia, "truth as un-concealment") + τέχνη (techne, "art, craft").
The art of revealing that a memory was not modified after being signed.
This is the reference implementation of the protocol specified in docs/implementacion-nucleo-minimo.md (rev 2 + rev 3 identity layer).
## what this is
alethech provides cryptographically verifiable, portable memory continuity for AI agents. It signs memory commits with Ed25519, links them in a hash-linked DAG, rotates keys without losing identity, and can seal a verified history into one encrypted .aleth file for transfer between compatible runtimes and devices.
What this repo IS:
A cryptographic protocol implementation (Ed25519 + SHA-256 + JCS RFC 8785)
An encrypted portable memory container (.aleth, scrypt + AES-256-GCM)
A neutral verified adapter view for plugins and chat integrations
A read-only MCP stdio bridge (python -m alethech.mcpmemory, or alethech-mcp after pip install alethech) exposing verified memory context and verification tools — credentials and paths stay configuration, never tool arguments
9 CLI commands (init, commit, evidence, verify, export, import, migrate, key rotate, key revoke)
A test suite with mutation-guard paths (each guarantee has a test that fails when the check is defeated)

What this repo is NOT:
The protocol core is not a hosted retrieval platform; the portable skill adds local encrypted memory workflows and bounded lexical recall
It is NOT the legacy memex project (Python/ChromaDB memory server)
It has no Docker, no auto-update, no LLM calls, no required cloud
It depends only on cryptography and click — no mem0ai, no chromadb, no ollama
The legacy memex codebase (167 commits, AliceLabs Proprietary License) is preserved in a separate repository: eddyflores100-lang/memex-legacy. It is not part of this repo and not installed by pip install alethech.
## the property
> This memory set forms part of a cryptographically verifiable history associated with a determined identity, whose commits can be independently verified with respect to their integrity, cryptographic authorship, and provenance relations.
> When a reference checkpoint exists, it can additionally be verified that the presented history continues from that checkpoint.
The protocol does NOT prove that the agent's claims are true — only that they were signed by the identity that claims them. The truth being un-concealed is the truth about transmission integrity, not about content.
## status
Released version 0.9.1 — portable encrypted memory (.aleth v2 with ALETH002 recovery across Python, TypeScript, and Rust) and chat capture into portable memory are live. CI runs the Python suite on 3.10–3.13 plus cross-language conformance and .aleth interoperability across Python, Rust, and TypeScript. No LLM, no required cloud, no blockchain, no consensus.
