This branch: https://github.com/TokenScript/TokenScript/tree/hotel-bogota/examples/sites/hotel-bogota

Pseudo code:

// this will open the iframe to attestation.id if first time
const useTicketProof  = Authenticator.generateAuthenticationBlob(selectedTicket);

// getting a challenge

const challenge = fetch(…)…

// sign a challenge contain

const msg = '{challenge: "' + challenge + '", proof: "' + atob(useTicketProof) + '"}'
const signedMsg = web3.eth.account.signMessage(msg)

// send the challenge back to the server

fetch(URL, {method: post, body: signedMsg;}).…

// get server greenlight, fetch privileged content
…

Operational Attributes

There are a few operational attributes, most importantly ownerAddress, however, it is not discovered until webster's code runs generateAthenticationBlob, which is confusing (as webster might not expect this function to change the token object. Therefore alternatively the function can be changed:

Authenticator.assertOwnerAddress(token) // this changes the token object

Which results in two operational attributes:

{
  devconID: 6,
  ticketID: 8080,
  ticketClass: 0,
  ownerAddress: 0xd55729e2A0C82b193cdb0d026f576f3ab5Aeac3e;
  ownershipProof: ArrayBuffer(…);
}

i.e. instead of returning the blob in a function call like originally planned, store it in the token object as Operational Attribute.
