Blocky Attestation Service
Blocky Attestation Service (Blocky AS) allows you to create attestations over responses from web APIs. Blocky AS attestations allow you to prove to a third party that a specific API returned specific data at a particular point in time.
Quick Start
To request and inspect your first attestation, follow these steps:
- Install the Blocky AS CLI
curl -s https://raw.githubusercontent.com/blocky/attestation-service-demo/main/install.sh | bash- Request an attestation with a API request template. Here we are creating an attestation over a trivia question and answer from Open Trivia Database.
echo '[{ "template": { "method": "GET", "url": "https://opentdb.com/api.php?amount=1" } }]' | \
./bky-as attest-api-call > out.json- Inspect the attested API response. (You may need to install
jq, if you don't have it already, to inspect JSON output.)
jq '.api_calls[0].claims.response.body | @base64d | fromjson' out.jsonIf you see a "response_code": 5, it means you hit the rate limit of the Open Trivia Database API. Thanks for trying the demo multiple times!
This quick start demo started a local instance of the Blocky AS server, which does NOT run in a Trusted Execution Environment (TEE). For access to Blocky AS deployed on production TEE servers, reach out to info@blocky.rocks.
Replit Demo
If you would like to try out Blocky AS without installing the CLI locally, you may run from our Replit template.
