Bloxi

A Blockchain implementation in Rust, based on the Learn Blockchains by Building One tutorial.

Mostly done as an exercise

How to run

RUST_LOG=INFO PORT=8082 cargo run --release

• RUST_LOG controls the log level
• PORT controls the port (defaults to 8088) the server runs at.

Endpoints

• GET /id: Returns the randomly generated node id
• GET /chain: Returns the current block chain
• POST /transaction: Adds a Transaction (e.g. { "from": 1, "to": 2, "amount": 100 })
• POST /mine: Mines a block based on the current transactions
• POST /node: Adds a node (e.g. { "address": "http://127.0.0.1:8081" })
• POST /reconcile: "Reconciles" the local chain with all known nodes

Explored

• Blockchains (duh)
• Actix actor model
  • Typed actors are sweeeet
  • A great way to eliminate blocking on a shared mutable resource
  • Integrates pretty well with Futures
• Actix web model
  • Quite easy to use with Serde
  • No coupling with Actix actors from what I've seen (good)

Todo

Lots to do, since this is a pretty faithful reproduction of the tutorial.

• Optimise (aka get rid of .clones and Boxes thrown in anger)
• Gossiping data (nodes, reconciling)
• Verifying Transactions are sound (currently just dumb data keeping)
• Moar tests
