Somnia: The Next-Generation Public Chain, Starting the Web3 Era for Mass Consumption

Abstract

Somnia is a high-performance, EVM-compatible Layer 1 blockchain co-developed by Improbable and the Somnia Foundation.

Somnia delivers over 1,000,000 TPS, sub-second finality, and near-zero transaction fees. Designed for real-time, mass-market consumer applications—including DeFI, AI, Prediction Markets, Gaming, and Social—it brings the scale and speed of Web2 into Web3 while maintaining a fully on-chain, asset-ownable, interoperable, and composable architecture.

With a total supply of 1 billion, the native Somnia token (SOMI) functions for paying Gas fees, validator and delegated staking, as well as future governance.

What Is Somnia

Currently, Web3 is still largely finance-centric. True mass-market consumer apps are heavily constrained by on-chain performance, high fees, and limited interoperability, making it challenging to achieve Web2-level scale and user experience.

Somnia is a Layer 1 EVM blockchain co-developed by Improbable and the Virtual Society Foundation (VSF). It is purpose-built for fully onchain application, with the capacity to process hundreds of thousands of transactions per second. The Somnia blockchain also features a comprehensive suite of full-chain protocols that connect web3 applications, NFT, and gaming ecosystems, enabling real-time, mass-market consumer apps to operate at Web2 scale while preserving Web3 principles of openness, ownership, and composability.

Key Technical Innovations of Somnia

Somnia's architecture is built around the principles of fully on-chain, real-time, and interoperable and composable systems. This design allows millions of users to participate in high-frequency, simultaneous interactions on a single chain, enabling assets, identities, and application logic to move seamlessly across digital worlds without being siloed by any single platform. These capabilities are powered by Somnia's suite of original technologies, which elevate EVM-chain performance by several orders of magnitude.

MultiStream Consensus Mechanism

In this architecture, each validator maintains an independent Data Chain and can produce blocks autonomously without requiring internal consensus. A separate Consensus Chain then leverages an enhanced PBFT algorithm to sequence and finalize all Data Chain headers. This design fully decouples data production from consensus, enabling true parallel block generation and achieving sub-second finality.

Compiling EVM Bytecode to Native Code

High-frequency contracts are translated using AOT compilation into x86 native code that approaches the speed of optimized C++, allowing for millions of TPS on one core. Low-frequency contracts are still executed using the standard interpreter, balancing speed and EVM compatibility. Furthermore, by incorporating modern CPU hardware features like out-of-order execution and superscalar processing, the internal execution speed of single transactions is dramatically accelerated.

Self-Developed IceDB Database

IceDB delivers read/write latency of 15–100 nanoseconds with fully deterministic performance, returning a performance report after each operation to enable precise billing. It features highly efficient read/write caching and built-in snapshot capabilities. This design eliminates the thousandfold latency fluctuations commonly seen in traditional embedded databases such as LevelDB and RocksDB.

Advanced Compression and Signature Aggregation Technology

High-Ratio Compression: Leverages the power-law distribution of transaction addresses and contract calls to achieve extremely high compression rates.

Streaming Compression: Supports continuous data publication by the same validator, enabling compression rates that significantly exceed standard block-level compression.

BLS Signature Aggregation: Aggregates thousands of transaction signatures into a single signature, drastically reducing bandwidth requirements. This approach can theoretically overcome the traditional "bandwidth wall," enabling near-Gigabit-level transaction data throughput.

These innovations allow Somnia to maintain full EVM compatibility while outperforming existing non-EVM high-performance chains. Additionally, this design mitigates the common issue in parallel execution where high-correlation workloads—such as NFT minting or highly popular trading pairs—cause failures.

Somnia's Product Advantages

Compared to other public chains, Somnia offers several key advantages, including extreme performance, full EVM compatibility, support for real-time applications, interoperable assets and logic, a gas-war-free environment, and a strong balance of decentralization and performance.

Extreme Performance: Somnia’s network design leverages highly concurrent execution and short block intervals, enabling it to achieve over 1,000,000 TPS, approximately 100 ms block time, and sub-second finality. This empowers developers to deploy applications requiring real-time on-chain feedback without execution bottlenecks.

Full EVM Compatibility: Somnia maintains consistency with the Ethereum toolchain, allowing existing contracts, wallets, and development frameworks to be migrated directly. This minimizes the cost and complexity of ecosystem switching.

● Support for Real-Time Applications

The network’s performance and latency metrics enable high-frequency interaction scenarios such as full-chain games, on-chain order books, and instant social platforms, delivering a user experience comparable to traditional applications.

● Interoperable Assets and Logic

Assets, characters, or logic from different worlds and applications can be reused across scenarios on the same chain, preserving resource liquidity within the ecosystem.

● No Gas-War Environment: High throughput significantly reduces the likelihood of network congestion during peak times, eliminating the need for ordinary users to compete for transaction timing by raising fees.

● Balanced Decentralization and Performance: Initially, the network will be operated by 60–100 professional validators (including participants such as Google Cloud), all adhering to high hardware standards to meet performance requirements. There are plans to gradually expand the number of validators over time.

● Reactive Blockchain: Somnia Data Streams is a real-time blockchain data subscription feature that delivers instant notifications when specific onchain events occur. Instead of constantly polling the blockchain or missing updates between checks, developers can subscribe to exactly the data they need and receive immediate notifications the moment relevant changes happen. This eliminates wasted queries and ensures applications stay perfectly synchronized with onchain state, enabling responsive user experiences for any application requiring live blockchain data.

SOMI Tokenomics

The native ecosystem token for Somnia is SOMI, which has a fixed total supply of 1 billion tokens with no future inflation. The token distribution is allocated as follows: 27.925% to the community, 27.345% to the ecosystem, 15.15% to investors, 15% to partners, 11% to the team, and 3.58% to advisors.

SOMI serves multiple utility functions within the network: (1) Gas fee payments, with 50% of gas revenue allocated to validators and the remaining 50% burned; (2) Validator staking, where operators must stake 5 million SOMI to run a node; (3) Delegated staking, allowing SOMI to be assigned to specific validators or a general pool, subject to a 28-day lock-up period, while emergency unstaking incurs a 50% penalty; and (4) Future network governance, where SOMI will play a key role in decision-making.

Conclusion

Somnia is more than just a "faster and cheaper" public chain; it represents the foundational infrastructure for the internet of the next decade—a fully on-chain, interoperable, real-time, large-scale virtual society.It elevates blockchain beyond a financial instrument into an "Operating System for Digital Civilization".On Somnia, games can evolve continuously, social accounts are fully user-owned, and virtual assets can flow seamlessly across countless worlds—all at speeds and costs comparable to Web2. When performance is no longer a bottleneck, Web3 truly begins. Somnia is making this future a reality.
