This demonstrates how to create and verify a Chainpoint proof using the Tierion Network. This live code notebook uses asynchronous Javascript code. The provided example is for demonstration purposes only. It lacks the error handling code necessary for a production application.

Lets get started!
const chp = require('chainpoint-client')
async function runIt () {
// A few sample SHA-256 hashes to anchor
let hashes = ['1d2a9e92b561440e8d27a21eed114f7018105db00262af7d7087f7dea9986b0a',
'2d2a9e92b561440e8d27a21eed114f7018105db00262af7d7087f7dea9986b0a',
'3d2a9e92b561440e8d27a21eed114f7018105db00262af7d7087f7dea9986b0a']
// Submit each hash to three randomly selected Nodes
let proofHandles = await chp.submitHashes(hashes)
console.log("Submitted Proof Objects: Expand objects below to inspect.")
console.log(proofHandles)
// Wait for Calendar proofs to be available
console.log("Sleeping 12 seconds to wait for proofs to generate...")
await new Promise(resolve => setTimeout(resolve, 12000))
// Retrieve a Calendar proof for each hash that was submitted
let proofs = await chp.getProofs(proofHandles)
console.log("Proof Objects: Expand objects below to inspect.")
console.log(proofs)
// Verify every anchor in every Calendar proof
let verifiedProofs = await chp.verifyProofs(proofs)
console.log("Verified Proof Objects: Expand objects below to inspect.")
console.log(verifiedProofs)
}
