Is Polaris still maintained or supported?

No, Polaris is deprecated as warned in the README, meaning there is no active development, bug fixes, or official support. It's not recommended for new projects.

How to integrate Polaris with Cosmos-SDK?

Check the documentation at polaris.berachain.dev and the 'cosmos' directory in the monorepo for integration code. However, due to deprecation, you might need to fork or seek alternatives.

What's better for EVM integration: Polaris or Geth?

Polaris is modular and tailored for easy integration into apps like Cosmos-SDK, while Geth is a full Ethereum client. Polaris offers configurability, but being deprecated, Geth is more reliable for active development.

What license does Polaris use and can I contribute?

Polaris uses BUSL-1.1 with plans for contributor-based schemes, but with deprecation, licensing changes are unlikely. Contribution is discouraged without maintenance.

Can I use Polaris in production?

Not advisable. The deprecated status means no security updates or compatibility fixes, posing significant risks for production environments. Opt for actively maintained solutions.

How to set up a local development network with Polaris?

Install Go 1.21+ and Foundry, clone the repo, and run 'make start' to launch a local network. Note that this is based on deprecated code and may have issues.

Are there performance benchmarks for Polaris?

The README claims optimization for performance, but specific benchmarks are not provided. With the project deprecated, any existing data may be outdated or incomplete.

What is Polaris?

Polaris is a modular framework for integrating the Ethereum Virtual Machine (EVM) into any application or consensus engine, such as those using Cosmos-SDK. It solves the problem of developers needing to hack together custom EVM integrations by providing a clean, configurable API and optimized components.

Target Audience

Blockchain developers and teams building applications that require EVM compatibility, especially those working with Cosmos-SDK or needing modular, high-performance EVM components.

Value Proposition

Developers choose Polaris for its modular design, ease of integration, and performance optimizations, which reduce development time and allow tailored EVM solutions without building from scratch.

Overview

Polaris is a modular implementation of the Ethereum Virtual Machine (EVM). It can be easily integrated into any consensus engine or application, including the Cosmos-SDK.

Use Cases

Best For

Integrating EVM into Cosmos-SDK based blockchains
Building modular blockchain applications with reusable EVM components
Developing high-performance EVM environments for crypto projects
Creating configurable EVM integrations for diverse use cases
Teams needing a clean API to avoid custom EVM hacking
Projects requiring tested and documented EVM packages

Not Ideal For

New projects requiring active maintenance and security updates
Teams seeking production-ready, stable EVM integrations with long-term support
Developers needing extensive documentation or community support beyond deprecated resources
Projects that cannot handle the complexity of Go 1.21+ and Foundry setup

Pros & Cons

Pros

Modular Design

Components are distinct packages with testing, documentation, and benchmarking, allowing flexible integration into diverse applications as described in the modularity principle.

Clean API

Provides an easy-to-integrate API that eliminates the need for custom EVM hacking, simplifying development for various blockchain use cases.

Performance Optimized

Built for high efficiency in competitive crypto environments, with optimization highlighted in the performance core principle.

Contributor-Friendly Plans

Plans to adjust licensing from BUSL-1.1 to support contributor-based schemes, encouraging open collaboration as per the README.

Cons

Deprecated Status

The project is explicitly deprecated with no active development or support, making it risky for adoption and future-proofing.

Complex Setup

Requires installation of Go 1.21+ and Foundry with specific environment configuration, which can be a barrier for quick onboarding.

Licensing Uncertainty

Current BUSL-1.1 license with planned changes introduces unpredictability for long-term usage and contribution, as admitted in the README.

Incomplete Features

Marked as work in progress with a disclaimer, indicating potential instability or missing functionality for production use.
