Data transaction of the Token Rating oracle

Once a day, the Token Rating oracle sends to the blockchain a data transaction with ratings and rates of tokens.

A data transaction contains the information about tokens, that have been rated in the past 24 hours.

A single transaction contains the information about no more than 25 tokens — if there are more rated tokens, then several transactions will be sent.

An example of a data array of such a transaction:

"data": [
  {
    "key": "assetRating_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb_1"
    "type": "integer",
    "value": 43,
  },
  {
    "type": "integer",
    "value": 28343,
    "key": "assetWeight_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
  },
  {
    "type": "integer",
    "value": 12,
    "key": "assetVotes_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
  },
  {
    "key": "scoreBoard_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
    "type": "string",
    "value": "{\"1\":{\"votes\":0,\"tokens\":0},\"2\":{\"votes\":1,\"tokens\":322},\"3\":{\"votes\":0,\"tokens\":0},\"4\":{\"votes\":0,\"tokens\":0},\"5\":{\"votes\":1,\"tokens\":1120}}",
  },
  ...
  {
      "type": "integer",
      "value": 45,
      "key": "tickerRating_1"
  },
  {
      "type": "integer",
      "value": 10000,
      "key": "tickerWeight"
  },
  {
      "type": "integer",
      "value": 11,
      "key": "tickerVotes"
  }
]

The key field is formed by concatenating a string that describes the parameter and a string with the ID of a token.

Key Type Description
assetRating_assetId_1 integer Rating of the token (multiplied by 10)
assetWeight_assetId integer WCT weight of the token
assetVotes_assetId integer Votes sum of the token
scoreBoard_assetId string The value the field contains an escaped string with rates.
tickerRating_1 integer Service parameter, which contains the value of the Rating (multiplied by 10), which must be at the token in order for the ticker to be set by its issuer
tickerWeight integer Service parameter, which contains the value of the WCT weight, which must be at the token in order for the ticker to be set by its issuer
tickerVotes integer Service parameter, which contains the value of the Votes sum, which must be at the token in order for the ticker to be set by its issuer

An example escaped string with rates

Let's say we have an escaped string with rates:

"{\"1\":{\"votes\":0,\"tokens\":0},\"2\":{\"votes\":0,\"tokens\":0},\"3\":{\"votes\":3,\"tokens\":545},\"4\":{\"votes\":0,\"tokens\":0},\"5\":{\"votes\":2,\"tokens\":3827}}"

Let's unescape that string:

{
  "1": {
    "votes": 0,
    "tokens": 0
  },
  "2": {
    "votes": 0,
    "tokens": 0
  },
  "3": {
    "votes": 3,
    "tokens": 545
  },
  "4": {
    "votes": 0,
    "tokens": 0
  },
  "5": {
    "votes": 2,
    "tokens": 3827
  }
}

It follows from the string that no one rated the token with one, two or four stars.

Three users rated the token with three stars. The sum of the weights Wn of those rates is 545.

Two users rated the token with five stars. The sum of the weights Wn of those rates is 3827.
