rchain_db

Coin transaction blockchain developed in rust

Implemented features

• RESTful HTTP Api (GET & POST)

  • GET /blockchain
    • Full blockchain data
  • GET /transactions/to_process
    • All transactions that will be added to the next block
  • POST /blocks
    • Mine a new block
  • POST /nodes
    • register a new node ("uuid": string, "url": string)
  • POST /nodes/resolve
    • Resolve conflicts between nodes by choosing the longest valid blockchain (consensus)
  • POST /transaction
    • add a new transaction ("amount": float, "receiver": string, "sender": string)

• Decentralized (nodes & consensus)

• Proof of work block validation

• Rewards for mining

• File storage to save state

Crates used

• Tide
• Serde
• JSON

Would be cool to implement

The project is fully functional and you can use it in a container environment to deploy multiple instances and play with consensus algo.

To permit this with docker

• Basic dockerfile
• Mount binary into
• Create a make directive to push a new blockchain instance thought a docker container given a port binding to 8880
• Register node using route POST /nodes
• Profit with your postman
