Exercise: Tezos Delegation Service

Build a service that :

• gathers new delegations made on the Tezos protocol,
• exposes them through a public API.

Requirements:

• The service will poll the new delegations from this Tzkt API endpoint: https://api.tzkt.io/#operation/Operations_GetDelegations

• For each delegation, save the following information: sender's address, timestamp, amount, and block.

• Expose the collected data through a public API at the endpoint /xtz/delegations.

  • The expected response format is:

  {
    "data": [ 
      {
          "timestamp": "2022-05-05T06:29:14Z",
          "amount": "125896",
          "delegator": "tz1a1SAaXRt9yoGMx29rh9FsBF4UzmvojdTL",
          "block": "2338084"
      },
      {
          "timestamp": "2021-05-07T14:48:07Z",
          "amount": "9856354",
          "delegator": "KT1JejNYjmQYh8yw95u5kfQDRuxJcaUPjUnf",
          "block": "1461334"
      }
    ],
  }

  • The sender’s address is the delegator.
  • The delegations must be listed most recent first.
  • The endpoint takes one optional query parameter year , which is specified in the format YYYY and will result in the data being filtered for that year only.

• Ensure the service is production-ready, considering factors like performance, scalability, error handling, and reliability.
