Lock.host-node

Lock.host node example, see: Lock.host

This demonstration uses OpenAI to control a Solana wallet:

• Unmodified OpenAI lib
• Unmodified Solana lib
• Hit /api/joke?message=your best joke&addr=abc123
• OAI is asked "You are to decide if a joke is funny or not"
• If so 0.001 SOL is sent to addr

Build app

This is how PCR hashes are checked:

just serve-alpine
just build-app
...
{
  "Measurements": {
    "HashAlgorithm": "Sha384 { ... }",
    "PCR0": "aaae1d110377748f8193d18de25739b8fdc6edc6bf22a7dc7b876272ef5b64febb139fe16427dcf722935a9a6eeb479e",
    "PCR1": "4b4d5b3661b3efc12920900c80e126e4ce783c522de6c02a2a5bf7af3a2b9327b86776f188e4be1c1c404a129dbda493",
    "PCR2": "5e83bd3182f9284ece7065ce8d79f42df15d7531f688e98ba42eeb9d101e3f34b7bd5c366f36048bc2d108e90c27dbca"
  }
}

See that run.yml is testing that PCRs in this readme match the build

Test

• In test a container emulates a TEE
• Two fifos /tmp/read and /tmp/write emulate a vsock

just serve-alpine
just build-test-app make-test-fifos
cp example.env .env
docker compose up -d
just joke 'why did the worker quit his job at the recycling factory? because it was soda pressing.'
...
addr = Do3F8NmohXPayS3xmos6CmqRXPD9DjCzK8Ct8sCc6UkA
sol = 0.002
json = {
  signature: '677Rtf2CcUonuh9f2UJhxLgmiX4EwQrR7vQ6CTydstdTExgqpUtgpy2HPYfmYVZRrYBvFnrQQpbTJW78oVw8zi1h',
  from: 'AkHqQ324DvygPxuhyYs9BTVG8b1BXzTnpbCxqG8zousm',
  to: 'Do3F8NmohXPayS3xmos6CmqRXPD9DjCzK8Ct8sCc6UkA',
  thoughts: "The joke plays on the pun between 'so depressing' and 'soda pressing', which is clever and light-hearted. It evokes a chuckle due to its wordplay."
}
sol = 0.003
(look inside node/joke.js)

Prod

• In prod all I/O passes through /dev/vsock

just serve-alpine
just build-app
just run-app
cp example.env .env
just run-host

Apks

Modify apk/Dockerfile.fetch to include all apks then run:

just proxy-alpine
just fetch-alpine
