## Introduction
Meter, a leading Layer-1 (L1) blockchain focusing on consensus and cross-chain infrastructure solutions, has recently introduced Supernova Core. This innovative open-source consensus framework is crafted to enhance Cosmos blockchain development and tackle performance and scalability challenges faced by existing solutions like CometBFT. In this article, we delve into the key features of Supernova Core and how it aims to revolutionize blockchain development within the Cosmos ecosystem.
### Building Blocks of Supernova Core
Meter’s Supernova Core leverages advanced technologies to offer a robust consensus framework compatible with the Cosmos SDK. Let’s explore the core components driving the development of this groundbreaking framework:
#### HotStuff Consensus Protocol and BLS Signature Aggregation
At the heart of Supernova Core lie the HotStuff consensus protocol and Boneh-Lynn-Shacham (BLS) signature aggregation. These cutting-edge technologies empower blockchain developers with efficient solutions while ensuring seamless integration with familiar frameworks, thereby spearheading innovation in the Cosmos ecosystem.
### Addressing Challenges in Cosmos SDK Development
Cosmos SDK-based blockchains encounter persistent scaling issues, such as bottlenecks arising from the increasing number of validators and limited support for Ethereum Virtual Machine (EVM) functionality. Supernova Core seeks to tackle these challenges head-on by offering:
#### Optimized Communication Layer and Enhanced Message Efficiency
By optimizing the communication layer and enhancing message efficiency, Supernova Core boosts throughput and facilitates seamless cross-chain collaboration, mitigating the limitations posed by the existing Cosmos SDK architecture.
#### Full EVM Compatibility
Supernova Core introduces full EVM compatibility, addressing the restrictions on EVM functionality within Cosmos SDK-based blockchains. This compatibility enhances interoperability and opens up new possibilities for decentralized applications running on the Cosmos network.
### Transformative Potential of Supernova Core
Xiaohan Zhu, Co-Founder of Meter, emphasizes the game-changing capabilities of Supernova Core in revolutionizing the existing Cosmos SDK consensus mechanisms. With innovative features like BLS signature aggregation, efficient network communication layer, and advanced consensus protocols, Supernova Core empowers developers to achieve unprecedented levels of scalability and performance.
## Supernova Core Features and Future Enhancements
