Clean code approach to blockchain technology. Learn blockchain by reading source code.
- 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 🚀 (Transactions, Wallet, Transaction relaying, Maybe some UI)
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
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)
