Somnia, the blockchain redefining scalability and efficiency, has launched Shannon Testnet, a key milestone on the road to mainnet. Named after Claude Shannon, the father of information theory, this testnet delivers a real-world environment for developers to build high-speed, scalable, and cost-effective blockchain applications.

Following Somnia’s DevNet breakthrough—1M+ TPS, sub-second finality, and sub-cent transaction fees—Shannon Testnet is set to push blockchain performance even further.
DevNet stress tests saw 3.6 million transactions processed across 300,000+ addresses, proving Somnia’s capability to handle real-world traffic.
Now, Shannon Testnet is here to stress-test congestion resistance and enable developers to build at a scale never seen before.
What’s New in Shannon Testnet?
Greater Decentralization – Multiple third-party validators are live, along with staking protocols to enhance network security.
Increased Stability – No more state wipes. Developers can build confidently without redeploying or replaying state.
Enhanced Developer Readiness – The full infrastructure stack is in place, ensuring a seamless development experience.
Ecosystem Growth – More projects are being onboarded to drive real adoption and test network performance.
Somnia’s testnet is fully equipped with everything developers need to build, launch, and scale. Key infrastructure partners are integrated, allowing projects to deploy instantly without waiting for additional tooling.
The Technology Powering Somnia
Shannon Testnet isn’t just another blockchain testnet—it’s the most advanced testing environment available today, powered by cutting-edge innovations:
MultiStream Consensus: Scaling Without Limits
Somnia’s breakthrough MultiStream Consensus enables parallel transaction execution, eliminating network slowdowns. This ensures speed, efficiency, and decentralization, even at extreme transaction volumes.
Additional Innovations Driving Performance
Accelerated Sequential Execution – Converts EVM bytecode into optimized native code, maximizing single-core performance.
IceDB (Deterministic Database) – A custom-built blockchain database achieving nanosecond-level read/write speeds.
Advanced Compression Techniques – Reduces bandwidth needs via streaming compression algorithms, supporting millions of TPS.
Unlocking New Blockchain Use Cases
With instant transactions and near-zero fees, Somnia opens the door to applications previously impossible on blockchain:
Reactive Applications – Smart contracts that respond instantly to real-world data, enabling real-time gaming, dynamic marketplaces, and automated financial services.
Fully On-Chain Gaming – Games with real-time mechanics, instant transactions, and decentralized economies, eliminating reliance on centralized servers.
Scalable DeFi Protocols – High-frequency trading, instant swaps, and congestion-free financial infrastructure.
Social Platforms & Metaverses – Scalable, interactive digital worlds supporting millions of users.
“Shannon Testnet is the proving ground for a fully on-chain future. With 1M+ TPS, sub-second finality, and MultiStream Consensus, developers can build without limits, and millions of users can experience blockchain at true internet scale.”
Paul Thomas, Founder of Somnia
What’s Next?
Shannon Testnet is a major step toward mainnet readiness. Over the coming months, developers will deploy, optimize, and stress-test applications while Somnia fine-tunes its infrastructure for mass adoption.
