Meter, a layer-1 blockchain pioneered in consensus and cross-chain infrastructure, has announced the launch of Supernova Core, a Cosmos SDK-compatible consensus framework.
In a press release shared with Cryptowisser, Meter explained that Supernova Core is designed to replace CometBFT, addressing performance and scalability challenges to enhance decentralization and performance for developers building on the Cosmos ecosystem.
This feature expands blockchain development by leveraging advanced consensus algorithms and cryptographic techniques like HotStuff and BLS. Supernova Core is fully compatible with Cosmos SDK and offers a seamless transition for developers seeking to integrate high-performance consensus solutions without abandoning familiar tools and frameworks.
Meter added that the consensus engine inside Supernova Core has been operational on its mainnet for over four years, supporting a network of more than 300 validators and handling peak transaction loads of up to 8 million transactions per day. Its extensive operations showcase its established reliability, efficiency, and resilience, even under adverse conditions.
According to Meter, the existing Cosmos SDK-based blockchains face numerous challenges, including limited scalability. These consensus mechanisms struggle to maintain throughput as validator counts grow. Performance bottlenecks arise from inefficient network designs and the overhead of validator consensus messages, which impedes scalability. Additionally, difficulties integrating Ethereum Virtual Machine (EVM) functionality limit opportunities for cross-chain development.
While commenting on the launch, Xiaohan Zhu, co-founder of Meter, said,
“With Supernova Core, we are empowering the community to overcome the limitations of existing Cosmos SDK consensus mechanisms. By introducing innovations like BLS signature aggregation, more efficient network communication layer, and the latest advancements in consensus protocols, Supernova Core enables developers to reach new heights of scalability and performance.”
Supernova Core solves these issues with BLS signature aggregation to reduce communication overhead and enable scaling beyond 150 validators. Furthermore, Supernova Core’s optimized peer-to-peer (P2P) network design enhances message efficiency and reliability through a layered network architecture. Advanced consensus mechanisms, built on the HotStuff protocol, deliver rapid transaction finality, higher throughput, and scalability with linear communication overhead. With a full EVM compatibility option, Ethereum-native tools and smart contracts integrate easily into Cosmos-based chains.
Its architecture decouples transaction ordering from state processing, providing the foundation for high-performance, decentralized L2 solutions. This innovation ensures censorship resistance and fairness while achieving the speed and performance of centralized alternatives.
According to Meter, Supernova Core is currently available for open source review and will be ready for testnet deployment very soon. Future updates will include support for parallel EVM execution and an optimized database tailored for Ethereum-style key/value store access patterns, further enhancing performance and developer experience.
Meter is a high-performance smart contract platform with freedom and fairness as the first principles. Highly decentralized, censorship- and MEV-resistant, and lightning fast, its native metastable coin completes Satoshi’s vision of sound money independent of the fiat system.
