Sign, hash-chain, and independently verify compute usage, portable across any provider.

ComputeLedger records a compute job's usage (GPU-hours, hardware, duration, workload type) as a cryptographically signed receipt and appends it to a tamper-evident local ledger. Anyone can verify a receipt's authenticity and the ledger's integrity without trusting the issuer, and without buying into any single cloud, chain, or vendor's stack.

Install

npm install -g computeledger-cli
pip install computeledger-cli

Both packages install the same computeledger command. Receipts are interoperable either way: a receipt signed by the npm binary verifies correctly with the PyPI binary, and vice versa.

Quickstart

$ computeledger keys generate --local
Generated Ed25519 keypair.
Public key: COxK/lkoWxWB42QKXjvcHnmBPozH4Oo2JHoOKDjsoU8=
Private key: ./.computeledger/keys/ed25519.pem (mode 600)

$ computeledger record --local --provider aws --hardware nvidia-h100 \
    --duration-seconds 3600 --gpu-hours 1 --workload-type training
Recorded usage receipt 39952199-0897-48b8-92c5-e351f773c83d.

$ computeledger ledger verify --local
Ledger valid: 1 entries, unbroken hash chain.

Or wrap a real job directly, no manual record call needed:

computeledger run --local --provider on-prem --hardware nvidia-a100 -- python train.py

run executes the wrapped command as a real subprocess (never through a shell), measures wall-clock duration, samples GPU utilization via nvidia-smi when one is present, and signs + appends the resulting receipt automatically. On a machine with no NVIDIA GPU, it still produces a duration-only receipt.

Give the receipt to anyone, on any machine, with no ComputeLedger account and no network call:

computeledger verify receipt.json
