Prethereum

Verifiable proofs for any computation. Ed25519 over SHA-256. TEE-backed signing, offline verification.

Verifiable proofs for any computation. Commit bytes, receive an Ed25519 signature over a SHA-256 digest. The proof is self-contained JSON. Verification is offline.

Security Model

Data flow:

• Commit sends only the bytes you explicitly provide to the notary. The tool does not scan, enumerate, or read files beyond what is specified.
• Verify is fully local. No data leaves your machine.
• Health sends an empty GET. No payload.

Notary behavior:

The notary runs inside an AWS Nitro Enclave (hardware-isolated TEE). It receives bytes, computes a SHA-256 digest, signs with Ed25519, returns the proof. The enclave has no persistent storage. Nothing is logged, stored, or forwarded.

Do not commit secrets. Bytes transit over HTTPS. Do not send credentials, private keys, or sensitive PII.

Network Behavior

Operation	Direction	Payload	Persistence
Commit	Client -> Notary	User-provided bytes (HTTPS)	None
Verify	Local only	None	N/A
Health	Client -> Notary	Empty GET	None

Requirements

• Node.js >= 20
• npm

Installation

text

npm install prethereum

For the MCP server, install globally with a pinned version:

text

npm install -g @prethereum/mcp@0.1.0

All packages are open source (Apache-2.0). Inspect before installing:

text

npm pack @prethereum/mcp@0.1.0 && tar -xzf prethereum-mcp-0.1.0.tgz

Quick Start

typescript

import { Constructor, StubHost } from "prethereum";

const host = await StubHost.create();
const ctor = new Constructor(host);

const proof = await ctor.commit(
  Buffer.from("Hello, world")
);

Verification

typescript

import { verify } from "prethereum";

const result = await verify({ proof, bytes });
// result.valid === true | false

HTTP API

bash

curl -X POST http://localhost:3030/commit \
  -H "Content-Type: application/octet-stream" \
  --data-binary @output.json
