Anoma

Overview

Anoma is a sovereign, proof-of-stake blockchain protocol that enables private, asset-agnostic cash and private bartering among any number of parties. To learn more about Anoma's vision, take a look at the Anoma Vision Paper or Anoma's Whitepaper.

This is an implementation of the Anoma protocol in Rust.

Warning

Here lay dragons: this codebase is still experimental, try at your own risk!

💾 Installing

There is a single command to build and install Anoma executables from source (the node, the client and the wallet). This command will also verify that a compatible version of Tendermint is available and if not, attempt to install it. Note that currently at least 16GB RAM is needed to build from source.

make install

After installation, the main anoma executable will be available on path.

To find how to use it, check out the User Guide section of the docs.

⚙️ Development

# Build the provided validity predicate, transaction and matchmaker wasm modules
make build-wasm-scripts-docker

# Development (debug) build Anoma, which includes a validator and some default 
# accounts, whose keys and addresses are available in the wallet
ANOMA_DEV=true make

Using Nix

nix-shell -p crate2nix --command "crate2nix generate"
nix-build -A apps
nix-env -i ./result

Before submitting a PR, pls make sure to run the following:

# Format the code
make fmt

# Lint the code
make clippy

🧾 Logging

To change the log level, set ANOMA_LOG environment variable to one of:

• error
• warn
• info
• debug
• trace

The default is set to info for all the modules, expect for Tendermint ABCI, which has a lot of debug logging.

For more fine-grained logging levels settings, please refer to the tracing subscriber docs for more information.

To switch on logging in tests that use #[test] macro from test_env_log::test, use RUST_LOG with e.g. RUST_LOG=info cargo test -- --nocapture.

Dependencies

The ledger currently requires that Tendermint version 0.34.x is installed and available on path. The pre-built binaries and the source for 0.34.8 are here, also directly available in some package managers.

This can be installed by make install command (which runs scripts/install/get_tendermint.sh script).
