Somnia | To a future where your NFTs can be used in any game. What is the "SOM0 Protocol" that achieves true interoperability?

The "metaverse," an open digital world where anyone can freely create, interact, and engage in economic activities. This is one of the grand visions of Web3. However, this ideal is now being hindered by a large "wall."

Current blockchain technology cannot simultaneously satisfy the three conditions required by the metaverse: "① ultra-high-speed processing power," "② interoperability to connect different worlds," and "③ low costs accessible to everyone." This challenge, also known as the "metaverse trilemma," has troubled many projects.

1. The Speed Wall: A metaverse with millions of users interacting in real-time far exceeds the processing capabilities of existing chains. As a result, many games are forced to rely on centralized servers for their core functions, moving away from the Web3 ideal of "decentralization."
2. The Interoperability Wall: You cannot use the ultimate sword or your favorite avatar obtained in one game in another. The more than 240 existing metaverses exist as isolated "walled gardens," hindering the birth of a massive digital economy.

To solve this deep-rooted problem, the L1 blockchain "Somnia" was born from "practice."

Somnia is not a project born from armchair theory. It was created when "Improbable," a British technology company that has been developing large-scale virtual worlds for over a decade, faced the reality that "no existing blockchain could meet the specs to realize the metaverse we want to build" and decided, "Then, we have no choice but to build it ourselves from scratch."

In other words, Somnia's design philosophy is based on the extremely practical knowledge of "what is truly necessary" to operate an internet-scale virtual society.

In this article, we will delve into the core of how this ambitious project is breaking down technological walls, connecting fragmented metaverses, and attempting to create a true "on-chain society."

The astonishing specs that Somnia boasts—"1 million TPS, sub-second transaction finality, and near-zero gas fees"—are realized through a combination of four innovative technologies.

1. MultiStream Consensus: No Congestion with "Multiple Lanes + High-Speed Checkpoint"

Many chains try to increase speed by parallelizing processes, but this can cause a bottleneck called "state contention" when traffic is concentrated on popular games, leading to congestion.

Somnia solves this problem with a completely new consensus algorithm, "MultiStream Consensus."

• Traditional Chains: Like customers rushing to a single cashier, where all cashiers (validators) have to confirm each transaction, creating a queue.
• Somnia's Method:
  1. Each validator processes transactions (checks out) at high speed in its own independent, dedicated lane (data chain).
  2. A separate, ultra-fast supervisor (consensus chain) instantly aggregates the receipts (blocks) from all lanes and finalizes the overall transaction record.

This separation of "processing" and "consensus" eliminates network-wide congestion, enabling an overwhelming processing capacity of 400,000 to 1 million TPS.

Somnia is EVM-compatible, meaning Ethereum apps can run on it. However, the way they run is completely different.

• Many EVM-Compatible Chains: They "interpret" Ethereum's program code as they execute it, sacrificing speed.
• Somnia's Method: It "compiles" the program code into a "native language" that the CPU can directly understand before executing it.

This achieves "near-native" speeds, approaching those of high-speed languages like C++. By deliberately avoiding parallel processing and maximizing single-thread performance, it fundamentally avoids the congestion problems caused by concentrated access. This is an extremely rational design philosophy, well-versed in the characteristics of the metaverse where "access concentrates on a few popular apps."

3. Custom Database "IceDB": Achieving Fair Gas Fees for "Pay-for-What-You-Use"

Blockchain speed is also affected by the performance of the database that stores data. Traditional general-purpose databases have unpredictable read times, forcing chains to set high gas fees by always assuming the worst-case scenario.

To solve this, Somnia developed its own custom database, "IceDB."

The key feature of IceDB is "deterministic performance." For every process, it returns a performance report that accurately records "how many resources were used." This allows Somnia to charge extremely fair and low gas fees based on the actual load the user placed on the system. It is truly a transparent "pay-for-what-you-use" system. This technology supports the ultra-low transaction fees of sub-cents (less than 1 cent).

4. Advanced Compression Technology and Reactive Primitives

Transactions at 1 million TPS also mean a massive amount of data. Somnia uses advanced compression technology, cultivated in the gaming industry, to efficiently transfer 10 to 20 times more data than other chains.

When these technologies combine, a magical feature called "reactive primitives" is born. This is a function that allows smart contracts to instantly react in real-time to on-chain events and data changes without relying on external servers.

For example, the moment you defeat a boss in a game, the blockchain can directly detect it and instantly send a reward NFT to your wallet without going through a central server, enabling a fully on-chain, interactive experience.

Somnia's true purpose is to connect fragmented metaverses and create a seamless "virtual society." The key to this is the "SOM0 Protocol."

Current NFTs only prove "ownership" of a digital asset. You can't use an NFT avatar from one game in another.

The SOM0 Protocol upgrades these NFTs into interoperable "metaverse objects."

• MML (Metaverse Markup Language): Like HTML, which defines the structure of web pages, this is a "blueprint" that standardizes the visual appearance and behavior (physics, animations, etc.) of avatars and items.
• Object Protocol: It links existing NFTs with records containing information like the location of the "blueprint," evolving them from mere proof of ownership to objects with specific appearances and functions.
• Attestation Protocol: A system where trusted third parties (official brands, age verification services, etc.) can grant a "stamp of approval" (attestation), such as "this is an official item" or "for ages 18 and up."

This allows you to freely carry your favorite avatars and items across various compatible metaverses. This is the realization of true interoperability that will dramatically increase the value of digital assets.

Furthermore, this protocol adopts an "omnichain" strategy that functions not just on Somnia but across all chains, including Ethereum and Solana. Through a partnership with Hyperlane, it will connect with over 150 other blockchains, with Somnia aiming to become the "hub" of all metaverse economies.

Somnia's competitors are other high-performance L1s like Solana and Aptos, but its positioning is distinctly different.

In short, Somnia is a "dedicated OS fully optimized for running real-time metaverses." This is its greatest technical advantage (moat) over other general-purpose L1s.

Furthermore, Somnia has a powerful weapon in its solid financial backing. The development entity has raised huge amounts of capital from world-class VCs like a16z and SoftBank. With this financial power, it is already bringing major Web3 infrastructure providers, large DEXs like QuickSwap, and promising game titles into its ecosystem one after another.

Somnia is steadily progressing with its plans.

• ✅ November 2024: Proved its technical capabilities by recording 1.05 million TPS on its developer network.
• ✅ February 2025: Launched the "Shannon" testnet, accessible to a wider range of users. Currently active.
• 🎯 During 2025: Plans to launch its mainnet. This will enable truly real-time dApps to be realized on-chain.

Somnia has also prepared a $10 million (approx. 1.5 billion JPY) grant program and is pouring all its efforts into expanding its ecosystem. It is a flawless strategy that turns the twin wheels of technological development and ecosystem growth.

A future token distribution (airdrop) from Somnia is highly anticipated. By participating in the testnet and contributing to the ecosystem, you might be able to seize that chance.

Here is a summary of actions you can take right now.

Important: Continuous involvement in the ecosystem, not just a one-time participation, is the key to future rewards.

Somnia is not just another fast L1 project. It is an extremely ambitious solution created "out of necessity" by on-site experts to solve the fundamental problems facing the metaverse.

Proprietary technology, solid financial backing, and a clear vision. There is no doubt that Somnia is one of the top contenders to open up the next frontier of Web3.

Of course, the L1 war is fierce. Ultimate success depends on its ability to attract many developers and users on top of its superior technology and to create "killer apps" that people get excited about.

If you've read this article, you should definitely try participating in the Somnia testnet. It's not just for the potential airdrop. The experience you'll gain will be a rare opportunity to witness firsthand where Web3 interactions are headed and to see a glimpse of the future.

Will the grand dream that Somnia envisions become a reality? The answer lies in the dynamism of the ecosystem that is about to begin.
