Nova

A rust-version cosmos-sdk fork from basecoin-rs

• bank - keeps track of different accounts' balances and facilitates transactions between those accounts.
• ibc - enables support for IBC (clients, connections & channels)
• dnn - deep neural network module for training

Requirements

So far this app has been tested with:

• Rust >v1.52.1
• Tendermint v0.34.10

Sepeficiation

1. rust version cosmos-sdk for rusters
2. offchain module for heavy computation ex. dnn
3. try to build golang compatible module from rust

Reference for main.rs

fn main() {
   let opt: Opt = Opt::from_args();
   let log_level = if opt.quiet {
       LevelFilter::OFF
   } else if opt.verbose {
       LevelFilter::TRACE
   } else {
       LevelFilter::INFO
   };
   tracing_subscriber::fmt().with_max_level(log_level).init();

   tracing::info!("Starting app and waiting for Tendermint to connect...");

   let app = BaseCoinApp::new(InMemoryStore::default()).expect("Failed to init app");
   let app_copy = app.clone();
   let grpc_port = opt.grpc_port;
   let grpc_host = opt.host.clone();
   std::thread::spawn(move || grpc_serve(app_copy, grpc_host, grpc_port));

   let server = ServerBuilder::new(opt.read_buf_size)
       .bind(format!("{}:{}", opt.host, opt.port), app)
       .unwrap();
   server.listen().unwrap();
}

Run your Node

Step 1: Reset your local Tendermint node

$ tendermint init
$ tendermint unsafe-reset-all

Step 2: Modify Tendermint config

Edit the Tendermint config.toml file (default location ~/.tendermint/config/config.toml) to update the proxy_app and P2P laddr as follows.

proxy_app = "tcp://127.0.0.1:26358"
# ...
[p2p]
laddr = "tcp://0.0.0.0:26356"

Step 3: Module specific setup

See the module documentation for more details -

• Bank module
• Ibc module

Step 4: Run the basecoin app and Tendermint

# See all supported CLI options
$ cargo run -- --help
tendermint-basecoin 0.1.0

USAGE:
    tendermint-basecoin [FLAGS] [OPTIONS]

FLAGS:
        --help       Prints help information
    -q, --quiet      Suppress all output logging (overrides --verbose)
    -V, --version    Prints version information
    -v, --verbose    Increase output logging verbosity to DEBUG level

OPTIONS:
    -g, --grpc-port <grpc-port>            Bind the gRPC server to this port [default: 9093]
    -h, --host <host>                      Bind the TCP server to this host [default: 127.0.0.1]
    -p, --port <port>                      Bind the TCP server to this port [default: 26658]
    -r, --read-buf-size <read-buf-size>    The default server read buffer size, in bytes, for each incoming client
                                           connection [default: 1048576]

# Run the ABCI application (from this repo)
# The -v is to enable trace-level logging
$ cargo run -- -v

# In another terminal
$ tendermint node
