Clean code approach to blockchain technology. Learn blockchain by reading source code.

Roadmap
-------

[](#roadmap)

- Block structure and hashing
- Genesis block
- Storing and validate Blockchain
- Proof of Work with difficulty (missing consensus on the difficulty)
- Communicating with other nodes & controlling the node (based on ReactPHP)
- Simple persistence layer
- Going serverless with AWS Lambda (experiment)
- Start working on KondasCoin [akondas/coin](https://github.com/akondas/coin) 🚀 (Transactions, Wallet, Transaction relaying, Maybe some UI)

Node
----

[](#node)

To start the node:

```
bin/node

```

Default web server port is 8080 but you can change it with `--http-port` param:

```
bin/node --http-port=9090

```

Default p2p server port is 3030 but you can change it with `--p2p-port` param:

```
bin/node --p2p-port=2020

```

API
---

[](#api)

To control node you can use simple (pseudo) REST API:

**\[GET\] /blocks**Response (list of all blocks):

```
[{"index":0,"hash":"8b31c9ec8c2df21968aca3edd2bda8fc77ed45b0b3bc8bc39fa27d5c795bc829","previousHash":"","createdAt":"2018-02-23 23:59:59","data":"PHP is awesome!","difficulty":0,"nonce":0}]

```

**\[POST\] /mine**Request (raw):

```
Data to mine (any string).

```

Response (mined block):

```
{"index":1,"hash":"a6eba6325a677802536337dc83268e524ffae5dc7db0950c98ff970846118f80","previousHash":"8b31c9ec8c2df21968aca3edd2bda8fc77ed45b0b3bc8bc39fa27d5c795bc829","createdAt":"2018-03-13 22:37:07","data":"Something goof","difficulty":0,"nonce":0}

```

**\[GET\] /peers**Response (list of all connected peers):

```
[{"host":"127.0.0.1","port":3131}]

```

**\[POST\] /peers/add**Request (json with peer):

```
{"host":"127.0.0.1", "port":"3131"}

```

Response: 204 (empty)
