# A high level blockchain monitoring library.

This library allows you to monitor blockchain events:

- new block

- new transaction for a particular address

- new confirmation for a particular transaction

It does so by using 4 different public API's:

- Blockbook (https://wiki.trezor.io/Blockbook)

- Blockcypher (https://www.blockcypher.com/dev/bitcoin/#introduction)

- Blockchain.info (https://www.blockchain.com/api)

- Blockchair (https://blockchair.com/api)

It uses 4 different API's for redundancy reasons. All events are normalized and de-duplicated.

Please note that this library does not contain any querying capabilities. Use the individual clients for that instead.

## Usage

A simple usage example:

```dart

import 'package:blockchain_monitor/blockchain_monitor.dart';

main() async {

  var monitor = new Monitor();

  Stream txs = monitor.address('some Bitcoin address');

  await for (tx in txs) {

    print(tx);

  }

  

  Stream confirmations = monitor.confirmations('some tx hash');

  await for (confirmation in confirmations) {

    print(confirmation);

  }

  

  Stream blocks = monitor.blocks();

  await for (block in blocks) {

    print(block);

  }

}

```
