2. Run the example

This runs the full protocol on your machine, in memory. It needs no server and no cloud account. It creates throwaway keys, so it is safe to run anywhere.

Requirements

• Node.js 22 or later
• pnpm (corepack enable activates it)
• Git

Steps

git clone https://github.com/pavancharak/dip.git
cd dip
pnpm install --frozen-lockfile
pnpm -r run build
node examples/sdk-quickstart.mjs

What you should see

authorization: ALLOW
execution: SUCCEEDED demo-1
ledger valid: true entries: 1

If any line differs, check 09-troubleshooting.md.

What the example does

The script in examples/sdk-quickstart.mjs does four things:

1. Declares and publishes an authority. It allows payments up to 50,000 INR to one resource.
2. Authorizes a request for 4,000 INR. The result is ALLOW.
3. Executes the action through the boundary and records the evidence.
4. Verifies the ledger it holds.

Read the file. Each numbered comment matches one step of 03, 04 and 06.

Run the full set of scenarios

node examples/run.mjs

This runs four scenarios: an allowed payment, a payment over the limit (DENY), tampered evidence (INVALID), and an authority revoked after an earlier ALLOW.
