License: GPL v3

Overview

Namada is a sovereign proof-of-stake blockchain, using Tendermint BFT consensus, that enables multi-asset private transfers for any native or non-native asset using a multi-asset shielded pool derived from the Sapling circuit. Namada features full IBC protocol support, a natively integrated Ethereum bridge, a modern proof-of-stake system with automatic reward compounding and cubic slashing, and a stake-weighted governance signalling mechanism. Users of shielded transfers are rewarded for their contributions to the privacy set in the form of native protocol tokens. A multi-asset shielded transfer wallet is provided in order to facilitate safe and private user interaction with the protocol.

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.

For more detailed instructions and more install options, see the Install section of the User Guide.

⚙️ 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

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_log::test, use RUST_LOG with e.g. RUST_LOG=info cargo test -- --nocapture.

How to contribute

Please see the contributing page.

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).
