[PRESS RELEASE – New York, United States, October 21st, 2025]

somniathe high-performance Layer 1 blockchain built for high-performance applications, has announced the upcoming launch of Somnia Data Flowsa new infrastructure layer that fundamentally changes the way developers handle real-time data on blockchain networks.

Traditional blockchain RPCs were designed for the scale of Ethereum and lack critical features that developers building real-time applications expect. Standard approaches require external indexers to constantly poll the blockchain for every call and data update, incurring significant technical costs and overheads. Somnia Data Streams solves this by introducing subscription-based RPCs built specifically for high-performance reads and writes on the Somnia network, processing over 1 million transactions per second with sub-second finality.

Instead of paying indexers to repeatedly query the blockchain, applications can subscribe to the specific information they need and receive automatic updates whenever state changes occur. This low-latency subscription model eliminates redundant transactions, reduces operational costs, and enables real-time responsiveness not previously possible on blockchain infrastructure. The result is a development experience that’s more like working with modern databases like Firebase, while maintaining all the security and verifiability benefits of blockchain.

Transforming prediction markets

Prediction markets have seen explosive growth recently, with platforms processing billions in volume and demonstrating massive demand for on-chain speculation beyond token trading. Despite this growth, the underlying technology remains surprisingly primitive. Most current prediction markets rely heavily on off-chain infrastructure, with oracles pulling results from external sources and settlement being done manually or through centralized third parties.

This limitation restricts the types of markets that platforms can offer. Complex and specific bets are difficult to support because there is no efficient way to verify the results and settle them instantly. When disputes arise, the platform must intervene and make decisions, making it an intermediary that users must trust.

Somnia Data Streams enables a different approach by allowing applications to subscribe to structured event streams. This capability allows for much more sophisticated markets. Instead of simple binary outcomes, users can bet on granular in-game events, such as which player scores the next goal, which driver completes the fastest lap, or specific performance metrics over defined time periods.

For racing applications, betting markets can directly access live timing data to track performance in real time. When the race concludes, payments are automatically executed based on verified results. For team sports, live possession statistics can change betting odds instantly depending on which team controls the ball. As the games unfold, participants see the odds adjust in real time to reflect actual events on the field.

This model adapts to any domain where structured event data exists on-chain, including esports matches, financial instrument movements, outcomes of governance proposals, and AI model performance metrics. If data flows through Somnia, a prediction market can be built around it.

Enabling automatic insurance products

The implications of real-time prediction markets for Somnia extend far beyond sports betting and gaming. A compelling application is insurance, where payments can be triggered automatically based on verifiable events rather than lengthy claims processes.

Traditional insurance involves significant delays and costs. When a flight is delayed, a crop is lost due to drought, or a natural disaster strikes, policyholders must file claims, insurers investigate, and settlements can take weeks or months. Administrative expenses increase costs, and disputes over coverage terms create friction when people need support most.

Somnia Data Streams allows insurance contracts to subscribe to event streams that track flight departures, weather data, seismic activity or any other measurable condition. When predefined thresholds are reached, payments are automatically executed. A flight delayed more than three hours generates immediate compensation. Rainfall below a certain level activates crop insurance. An earthquake greater than a specific magnitude releases disaster relief funds.

This approach eliminates the need for claims adjusters, reduces processing costs, and eliminates disputes over whether an event qualifies for coverage. The data is on chain and verifiable. The contract is executed deterministically. Policyholders receive funds instantly when they need them most, without paperwork or waiting periods.

This creates opportunities for new types of coverage that were not previously economically viable, including microinsurance for the self-employed, event cancellation protection for small venues, and yield protection for individual farmers. The administrative costs that made these products unprofitable in traditional insurance disappear when settlement is automatic and does not require trust.

Availability and access

Somnia Data Streams with full on-chain reactivity will be available early next year, with subscription RPCs rolling out first in the coming months. Developers interested in early access can register at the mailing list to receive a notification when the SDK is available.
