# Shannon Testnet goes live as Somnia gears up for mainnet launch

Somnia, a high-speed, Ethereum-compatible blockchain, launched its Shannon Testnet today as part of its push toward mainnet readiness.

Named after information theory pioneer Claude Shannon, the testnet follows DevNet benchmarks exceeding 1 million transactions per second (TPS), offering developers a scalable platform for real-world applications.

The Shannon Testnet introduces multiple third-party validators and staking protocols, enhancing decentralization and security. During DevNet testing, it processed over 3.6 million transactions across 300,000+ unique addresses, with sub-second finality and sub-cent transaction fees.

“Shannon Testnet is the proving ground for a fully on-chain future,” Somnia founder Paul Thomas said in a statement to crypto.news, emphasizing its ability to handle millions of users at internet scale. This launch provides developers with an opportunity to stress-test applications under real-world conditions.

Somnia’s website outlines the testnet’s rollout, supported by infrastructure partners for seamless app deployment. The company claims its MultiStream Consensus enables parallel transaction execution without slowdowns, making Shannon a key testing ground for congestion resistance.

## Tech and use cases driving shannon testnet

Somnia’s tech stack includes accelerated sequential execution and IceDB, a high-speed database with nanosecond-level read/write speeds.

> “ *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*,”

Thomas noted. These features aim to support reactive apps, on-chain gaming, scalable DeFi, and metaverse platforms.

## Context from the blockchain space

This launch aligns with a trend of blockchain testnets gearing up for 2025 mainnets. Ethereum’s Spectra Devnet5, launched in January 2025, targets a March mainnet debut with sharding upgrades for scalability, per a recent crypto.news report. Meanwhile, Hyperliquid’s HyperEVM testnet, live since late 2024, focuses on DeFi innovation with rapid transaction processing, fueling 2025 hype.
