Meter, a Layer-1 (L1) blockchain known for its work in consensus and cross-chain infrastructure, has unveiled Supernova Core, a new open-source consensus framework compatible with the Cosmos (ATOM) source development kit (SDK), as reported to Finbold on Thursday, January 16.
Supernova Core will address performance and scalability issues associated with CometBFT while promoting decentralization within the Cosmos ecosystem.
At the core of the framework is the HotStuff consensus protocol and Boneh-Lynn-Shacham (BLS) signature aggregation, which allows blockchain developers to leverage new solutions without abandoning already established frameworks.
The core has been tested on the Meter mainnet, which supports a network of more than 300 validators and manages nearly eight million daily transactions.
Troubleshoot issues with the Cosmos SDK
Cosmos SDK-based blockchains face ongoing scaling challenges, for example bottlenecks caused by the growing number of validators.
In turn, the bottleneck limits throughput, while limited support for Ethereum (ETH) Virtual Machine (EVM) functionality limits cross-chain collaboration.
Supernova Core addresses these issues head-on by offering an optimized communications layer, improved messaging efficiency and full EVM compatibility.
Highlighting the transformative potential of Supernova Core, 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 such as BLS signature aggregation, a more efficient network communications layer and the latest developments in consensus protocols, Supernova Core enables developers to reach new heights of scalability and performance.”

Compatibility of meter EVM
Supernova Core is designed to reduce communication overhead and enable networks to scale beyond 150 validators.
The layered peer-to-peer (P2P) network architecture ensures efficient message delivery, while the HotStuff-based consensus mechanism ensures fast transactions and linear scalability of the communication overhead.
The framework’s architecture also separates transaction ordering from state processing to enable advanced Layer-2 solutions and promote censorship resistance.
Future updates will include parallel EVM execution capabilities and an optimized database tailored to Ethereum-inspired key-value access patterns.
