Polymarket releases a new version of the Oracle Machine, only the "Efficiency Allowlist" can propose listings for predictions.

Polymarket upgrades the Oracle Machine to MOOV2, introducing an Allowlist system to enhance efficiency, while also sparking new controversies. (Background: Elon Musk's AI enters the prediction market: using Grok to empower Kalshi's trading revolution) (Context: Polymarket spends $112 million to acquire the exchange QCEX, with U.S. compliance tickets in hand, is the next step to issue coin?) Today (12), the decentralized prediction market platform Polymarket announced the upgrade of the OOV2 Oracle Machine to MOOV2, introducing the "Proposal Allowlist" system. As soon as the news broke, the Blockchain community immediately engaged in heated discussions, questioning whether it included centralized concerns. Incentives for Efficiency In the old version of OOV2, any address could submit proposals, theoretically achieving complete openness, but in practice, problems were rampant. Newbies lacked judgment and often lost Margin when submitting ambiguous or incorrect markets, while experienced users struggled with prolonged Settlement latency lasting several days. The most representative case is the NASCAR market controversy, involving about $60,000, where the Settlement time was repeatedly extended, consequently slowing down capital turnover and diminishing the platform's immediacy. Polymarket pointed out that MOOV2 hands over proposal rights to Allowlist members, who can first coordinate topics through channels like Discord, and then have trusted addresses go on-chain, expecting to shorten the average Settlement time to within one day. From a product perspective, this change addresses three major pain points: reducing risks for newbies, preventing Margin abuse, and enhancing market Liquidity. PolymarketGuide provides an explanation of the new version's procedures. Controversy The current community's dispute arises from the concentration of proposal power in a few addresses, questioning whether Decentralization becomes a mere facade. How Allowlist members are generated, whether they can be publicly audited, and how to assign responsibility in case of errors are all focal points that the community is eager to clarify. Polymarket acknowledges in official documents that while restrictions can improve quality, they inevitably bring about centralized risks. Supporters argue that specialized proposals help reduce the rate of disputes to a controllable level; opponents, however, question that once the Allowlist forms a closed circle, the adjudication of real events may be swayed by a few individuals. Additionally, the dissent mechanism remains open to all addresses, theoretically preserving the community's power of final arbitration. However, if the initial proposal deviates, the subsequent rebuttal process may increase time and costs, ultimately detrimental to the original intention of "everyone can verify." The Dilemma of the Oracle Machine The Oracle Machine serves as an important bridge connecting on-chain contracts to real-world events, often pulled between transparency and efficiency. Historically, OP Oracles, including UMA, have often fallen into arbitration deadlocks due to ambiguous events in politics, sports, etc. Members of the community have repeatedly mentioned issues with the UMA Oracle. In the new controversy that Polymarket faces regarding "Did Xiao Ze wear a suit or not?", UMA's Oracle design again illustrates that "incentives often do not output facts/truths, but merely stimulate surface-level consensus in the game." - This topic was actually discussed with @WutalkWu in the latest episode of Web3 101 podcast. Polymarket relies on the UMA Oracle to determine event outcomes, but this design does not necessarily ascertain facts. - Feng Liu (@fishkiller) July 10, 2025 Polymarket chooses to first address speed and misuse issues, then reduce error rates through Allowlist reviews, reflecting the real pressure that the Blockchain prediction market must face in scaling. If completely adhering to no thresholds, platform operations and capital flows may stagnate. If power is highly centralized, it may easily shake users' trust in Decentralization.
