Polymarket Enhances Prediction Market Transparency with Embedded Data Sources

**UMA's Optimistic Oracle** lets you earn rewards by proposing correct answers to onchain data requests. **What you can propose:** - Asset prices - Sports outcomes - Governance results - Hack confirmations - Cross-chain transfers - IP disputes - Any verifiable public data **How it works:** 1. Visit the [UMA OO dApp](https://oracle.uma.xyz/propose) 2. Choose a live query 3. Post a bond + your answer 4. If unchallenged during the liveness window, earn rewards **Risk/reward structure:** - Correct proposals = earn posted rewards - Wrong proposals = lose your bond You can build bots to automate proposal monitoring, though UMA doesn't provide these services directly.

UMA has officially surpassed **$2 billion in total value secured**, marking a significant milestone for the optimistic oracle protocol. This achievement demonstrates growing adoption of UMA's oracle infrastructure across the web3 ecosystem. The protocol continues to expand its role in securing decentralized applications and protocols. The milestone comes as UMA's Optimistic Oracle has previously processed over $25 billion in total transaction value, highlighting the platform's established track record in the oracle space.

The oracle narrative continues its evolution in 2025, building on previous developments from 2023 and early 2025. **Key Development:** - The oracle has transformed from a simple prediction mechanism to an "optimistic" system - This represents a significant upgrade in oracle technology and functionality **Background Context:** - Previous iterations focused on basic oracle functions and probability mastery - The species evolved through logical analysis rather than chance - Current development suggests enhanced capabilities in cross-protocol operations **Technical Implications:** - Optimistic oracles typically allow for dispute mechanisms and delayed finality - This approach can reduce costs while maintaining security - Integration with snapshot governance systems appears to be a focus The evolution from basic oracle to optimistic oracle represents a meaningful step in decentralized prediction and verification systems.

**UMA Protocol** has initiated voting on UMIP 190, a comprehensive housekeeping proposal affecting **six blockchain networks**. The proposal includes: - **Whitelist pruning** across Ethereum, Polygon, Arbitrum, Optimism, Base, and Blast - Removal of **40+ deprecated currencies** including DAI, WBTC, AAVE, LINK, and UNI - **Fee reductions** for WETH (0.135 → 0.055) and ABT on all supported chains - **Retirement of Boba chain** messenger support The changes are split into **four separate proposals** to maintain auditability. All removed currencies will have their final fees reset to zero. *This is routine maintenance* - no new functionality is introduced. Removed currencies can be re-whitelisted if future use cases emerge.

Across Protocol has unveiled Version 4 of their bridge solution, marking a significant technical upgrade to their infrastructure. - Integration with Succinct Labs brings enhanced zero-knowledge proof capabilities - Security framework reinforced through UMA Protocol's optimistic oracle system - New version aims to improve cross-chain transaction efficiency The collaboration represents a strategic enhancement of Across's bridging architecture, combining Succinct's ZK technology with UMA's battle-tested security mechanisms.
