TNA

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

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.

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