About CoinDataBase project

TLDR; Get me to the list of coins

CoinDataBase is a database of crypto currencies basic properties like market symbol, website, privacy/scalability/governor features, etc.

The main idea of database is to provide not only the data but also proofs - URLs of web documents providing details about the values specified in database (see Policy for adding/changing data below).

This database would be useful to all people studying the crypto world.

Feel free to submit pull requests with new coins or corrections of existing data.

How to add new coin

Fork the repository.

Copy coin_template.json to coin/ directory and name it with coin name. Use common coin name, do not lowercase all letters, use underscore instead of space.

Good names:

  • Ethereum_Classic.json
  • NEM.json
  • iDice.json

Bad names:

  • Ethereum Classic.json
  • ethereum_classic.json
  • Nem.json
  • nem.json
  • idice.json

Edit the new file and fill all coin propertes you know. If you do knot know or do not understand some properties just put "?" string there. Do not delete keys, just put "?" string e.g.:

"tx_per_second": "?"

Keys which names ends with "_url" are list of urls. They could contain up to 3 items. Each item have to be valid URL.

The required minimum set of non-blank properties to add new coin is:

  • name
  • symbol
  • website_url

Add link to new coin file to README.rst. List of coins are sorted in alphabetic order.

When you are ready create pull request and check in few minutes if automatic travis tests passed. Travis checks your changes for missing keys, invalid data types and other possible mistakes. If pull requests passed the tests I'll merge it in main repo or will write comment if something concerns me.

References property

The "references" key points to object which keys are the usual coin properties and values are list of urls to web documents that proofs the value of the corresponding coin property is correct e.g.:

"references": {
    "tx_min_fee": [

Each list could contains up to 3 items.


Numbers could be specified in short form using suffixes K (thousands), M (millions) and B (billions) e.g. 21M equals to 21000000

Values of block_size key have to used another suffixes: KB (kilobytes) and MB (megabytes).

For boolean properties like anonymous the "yes" and "no" values must be used.

If the property can not be applied to the coin e.g. masternode_supply for Ethereum, set the value to "NA" (not applicable).

If the value is unlimited use "Inf" string e.g.:

"max_supply": "Inf"

Policy for adding/changing data

For any property except name, symbol and %_url one of the rules have to be satisfied:

  • the value of property is "?" or empty list
  • at least one proof URL exists at corresponding key in references property

Properties name, symbol and %_url do not require proof URLs. But they could be annotated with proof URLs if you think it makes sense.

How to validate data

This is completely optional.

In case of you want to run tests on your local machine you will need python interpreter.

Install additional libraries with command:

pip install pytest
pip install jsonschema

Now run test with command:


Also you can just send github pull request and wait few minutes for travis CI makes testing for you. You'll see results of testing inside your pull request on github.
