Coretime Dashboards

Overview​

Coretime is a parachain on Polkadot that focuses on time-stamping and data certification, providing a decentralized and secure mechanism for verifying data integrity.

Here you will find a variety of dashboards that help visualize data from the Coretime parachain:

Please also visit our dashboards for Coretime on Dune Analytics.

Key Tables​

Data from the Coretime parachain is organized into several key tables:

  • coretime.balances
  • coretime.blocks
  • coretime.calls
  • coretime.events
  • coretime.extrinsics
  • coretime.transfers

Getting Started with Queries​

To get started with querying data from Unique, you are welcome to use the mentioned materialized queries. You can use the following DuneSQL queries as examples:

Kusama Coretime Core Statistics
WITH
  core_sta as (
    SELECT
      block_time,
      get_href (
        'https://nodle.subscan.io/extrinsic/' || cast(extrinsic_id as VARCHAR),
        extrinsic_id
      ) as extrinsics_url,
      extrinsic_id,
      CAST(JSON_EXTRACT_SCALAR(data, '$[0]') AS BIGINT) as sale_start,
      CAST(JSON_EXTRACT_SCALAR(data, '$[1]') AS BIGINT) as leadin_length,
      CAST(JSON_EXTRACT_SCALAR(data, '$[2]') AS BIGINT) / pow(10, 12) as start_price,
      CAST(JSON_EXTRACT_SCALAR(data, '$[3]') AS BIGINT) / pow(10, 12) as regular_price,
      CAST(JSON_EXTRACT_SCALAR(data, '$[4]') AS BIGINT) as region_begin,
      CAST(JSON_EXTRACT_SCALAR(data, '$[5]') AS BIGINT) as region_end,
      CAST(JSON_EXTRACT_SCALAR(data, '$[6]') AS BIGINT) as ideal_cores_sold,
      CAST(JSON_EXTRACT_SCALAR(data, '$[7]') AS BIGINT) as cores_offered,
      CAST(
        ROW_NUMBER() OVER (
          ORDER BY
            block_time ASC
        ) AS BIGINT
      ) AS sale_round
    FROM
      coretime_kusama.events
    WHERE
      section = 'broker'
      AND method = 'SaleInitialized'
  )
SELECT
  *,
  get_href (
    'https://dune.com/substrate/kusama-coretime-sales-history?sale_round=' || cast(sale_round as VARCHAR),
    cast(sale_round as VARCHAR)
  ) as sale_round_url
FROM
  core_sta
ORDER BY
