Brevis Brings Trustless Data to Opinion: The Future of Prediction Market Settlement

[read_meter]

TL;DR

We are delighted to announce a strategic partnership between Brevis and Opinion, a leading prediction market protocol on BNB Chain. This collaboration marks a pivotal moment for both platforms as we build a more trustless, efficient, and scalable prediction market ecosystem.

Opinion is integrating Brevis’s zkCoprocessor and Pico zkVM to power its off-chain public data oracle infrastructure, enabling it to deliver prediction market resolutions with mathematical certainty. This partnership expands Brevis’s verifiable computing stack into a new and high-impact vertical where data integrity is fundamental to market credibility. For the BNB Chain ecosystem, this collaboration exemplifies how zero-knowledge infrastructure can unlock new possibilities beyond conventional DeFi, driving both efficiency and trustlessness across a variety of protocols.

How Brevis Empowers Opinion with zkCoprocessor

Prediction markets live or die by their ability to settle accurately. When an outcome depends on external events (whether that’s a CPI release, a sports result, or a geopolitical development), the market must have a way to verify what actually happened at a specific point in time. Historically, this meant counting on centralized data providers, oracle networks requiring multi-party consensus, or subjective human judgment.

Brevis’s zkCoprocessor and Pico zkVM fundamentally change this dynamic. When Opinion needs to resolve a market based on off-chain data, say fetching the latest inflation report from a government website, Brevis’s tech proves that data fetched from a web source (e.g. https://www.census.gov/ for CPI) is:

  • Authentic: fetched through a genuine TLS session from the target domain.
  • Untampered: cryptographically proven identical to the original source content.
  • Interpretable: processed by a zkVM to extract relevant data (e.g., CPI = 3.1%).

For example, when a CPI release webpage is published, Brevis’s zkCoprocessor fetches and proves the page authenticity. Pico zkVM then parses the HTML or JSON to extract the numeric CPI value. The proof of both the fetch and computation is verified on-chain, creating a trustless, one-step resolution for prediction markets dependent on real-world data.

This approach scales across Opinion’s ecosystem. Whether Opinion needs to incorporate macroeconomic data, sports outcomes, or real-world events, each resolution benefits from the same mathematical guarantees that have already proven themselves across DeFi protocols managing billions in value.

Why This Matters 

The implications of this partnership run deep, touching every aspect of Opinion’s platform and user experience.

Integrating Brevis’s zkCoprocessor represents a fundamental upgrade to market credibility. Prediction markets succeed when participants trust that settlements are fair, transparent, and beyond manipulation. Cryptographically provable data authenticity at the data source level strengthens settlement transparency and verifiability, reducing disputes. This builds confidence among traders, liquidity providers, market makers, and institutional participants who require a high assurance of fair resolution.

The benefits for users are equally tangible. Trustless settlements mean faster market closure. Once Brevis’s proof is verified on-chain, there’s no waiting for subjective human review, accelerating capital release and enabling tighter market cycles. Users gain certainty that no off-chain intermediary can influence the resolution process. The data source and the computation are both fully on-chain verifiable.

The integration also opens the door for Opinion to expand its market catalog. With zkTLS-verified data, Opinion can offer markets tied to literally any publicly available real-world data source (from commodity prices published by exchanges, to election results released by official channels). Each market benefits from the same layer of cryptographic assurance.

For the broader BNB Chain ecosystem, this partnership shows that prediction markets can achieve the kind of robust infrastructure combining speed, low costs, and deep security that makes them a genuinely practical alternative to traditional forecasting and hedging mechanisms. 

Continued Collaboration

This integration of Brevis’s zkCoprocessor into Opinion’s infrastructure is just the beginning of our collaboration. Opinion and Brevis are exploring multiple avenues of partnership, with collaborative initiatives to further enhance Opinion’s capabilities and solidify its position as the leading prediction market protocol on BNB Chain. 

We invite the community to explore Opinion’s platform and experience firsthand how Brevis’s zero-knowledge technology delivers a new standard of trustless, tamper-proof settlement. 

About Opinion

Opinion is building a series of trading infrastructures that enable direct trading of macroeconomic data, predictions, and news as standardized assets, leveraging proprietary on-chain infrastructure, AI Oracle, and trading tools to create new opportunities for retail users, institutions, and global decision makers in democratizing economic insights and risk management.

Macro trading remains largely inaccessible due to infrastructure limitations and expensive institutional tools. Both retail and institutional investors currently lack direct access to economic indicators like inflation and interest rates, instead relying on trading volatile proxies. Opinion creates a prediction exchange with integrated data dashboards and trading tools, enabling anyone to directly trade macro indicators and news outcomes while democratizing access to sophisticated financial instruments previously reserved for institutions.
