TNA

TNA translates raw bitcoin transaction into bitdb document format, which allows for powerful queries into the bitcoin universe.

protein

TNA can be used as a standalone tool for quickly making sense of bitcoin raw transactions, and also powers bitd which stores the transformed format into MongoDB to form the basis of BitDB.

Installation

npm install --save tna

Usage

There are two methods:

  1. fromHash: Generates bitdb document from transaction hash. (requires a local bitcoin node for JSON-RPC)
  2. fromTx: Generates bitdb document from raw transaction (Local operation and doesn't require a bitcoin node)

1. fromHash

Generate bitdb document format from transaction hash

const TNA = require('tna');
(async function() {
  let result = await TNA.fromHash("3a737de7faa2ae1914f57ca0a11fd471334e40d4079d98cd77d27727e388b09d")
  console.log(result)
})();

prints:

}

2. fromTx

Generate bitdb document format from raw transaction string.

The following code does the same thing as the fromHash example above, but doesn't require a bitcoin node since it's directly transforming from raw transaction.

const TNA = require('tna');
(async function() {
  let result = await TNA.fromTx("0100000001d5001345e77e66fa74f0012a81017ea1223c7a8adbcc9e37f2860f95ba97966d000000006b483045022100c1a0c5ffc5b78e39acb5be1438e28a10e5aac8337f5da7e4c25ba4c5f3eb01b5022050e9997bae423585da52d7cdc8951379f5bff07adb6756ffe70e7c7181f8a5bd4121032b345f89620af75f59aa91d47cc359e4dd907816ce0652604922726025712f52ffffffff024a976200000000001976a914c6187747f80b85170eef7013218e7b0fa441479988ac44033f00000000001976a9147e4616b7453185a5f071417bb4ac08e226dbef9888ac00000000")
  console.log(result)
})();
