Namada is the first release protocol version and the first fractal instance of the Anoma protocol. 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.
Namada is two things:
- The first major release version of the Anoma protocol.
- The first fractal instance launched as part of the Anoma network.
The Anoma protocol is designed to facilitate the operation of networked fractal instances, which intercommunicate but can utilise varied state machines and security models. Different fractal instances may specialise in different tasks and serve different communities. The Namada instance will be the first such fractal instance, and it will be focused exclusively on the use-case of private asset transfers.
Safe and user-friendly multi-asset privacy doesn't yet exist in the blockchain ecosystem. Up until now you had the choice to build a sovereign chain that reissues assets (e.g. Zcash) or to build a privacy preserving solution on existing chains (e.g. Tornado Cash on Ethereum). Both have large trade-offs: in the former case users don't have assets that they actually want to use and in the latter case the restrictions of existing platforms mean that users leak a ton of metadata and the protocols are expensive and clunky to use.
Namada can support any asset on an IBC-compatible blockchain and assets (such as ERC20 tokens) sent over a custom Ethereum bridge that reduces transfer costs and streamlines UX as much as possible. Once assets are on Namada, shielded transfers are cheap and all assets contribute to the same anonymity set.
Namada is also a helpful stepping stone to finalise, test, and launch a protocol version that is simpler than the full Anoma protocol but still encapsulates a unified and useful set of features. There are reasons to expect that it may make sense for a fractal instance focused exclusively on shielded transfers to exist in the long-term, as it can provide throughput and user-friendliness guarantees which are more difficult to provide with a more general platform. Namada is designed so that it could evolve into such an instance.
