GoPlus: Polymarket Hacked, Flaws in Off-Chain and On-Chain Transaction Result Synchronization Mechanism

According to disclosures from the GoPlus Chinese community, the prediction market platform Polymarket was hacked due to a design flaw in the synchronization mechanism between off-chain and on-chain trading results in its order system.The attacker manipulated the nonce, causing on-chain matched trades to be canceled or invalidated before execution, while off-chain records remained valid, leading to API false reports that affected trading behaviors of bots like Negrisk, resulting in user losses. The analysis of the attack process is as follows:The attacker submitted/matched large reverse trades with the market-making bot on the Polymarket off-chain orderbook.The attacker constructed transactions with forged/repeated nonces or utilized on-chain nonce competition, causing the on-chain transactions to inevitably revert.The Polymarket API returned "transaction successful" to the bot before on-chain confirmation, leading the bot to believe that the position had been hedged, while the actual on-chain state had not changed.The attacker then executed real on-chain trades to take advantage of the direction exposed by the bot, thus profiting "risk-free."Since the revert occurred at the chain level, Polymarket fees would not explode, making the attack cost controllable and executable continuously.GoPlus recommends that users pause automated trading tools, verify on-chain trading statuses, enhance wallet security, and closely monitor official announcements from Polymarket.

Brevis co-founder Michael: In the next decade, 99% of blockchain computing will move off-chain, and ZK proofs will become key infrastructure

At the "Build and Scale in 2026" themed forum held by ChainCatcher in Hong Kong, Michael, co-founder & CEO of the ZK verifiable computing platform Brevis, delivered a keynote speech on "The Infinite Computing Layer Where Everything Can Be Computed," sharing how ZK technology is driving a fundamental transformation in the blockchain computing paradigm.Michael pointed out that the current on-chain computing costs are high and the speed is slow. The "verifiable computing" paradigm proposed by Brevis can offload heavy computations to off-chain, requiring only low-cost verification on-chain, achieving decoupling of computation and verification while supporting privacy protection scenarios.The speech showcased the performance breakthroughs of Brevis's core product, Pico ZKVM: its latest generation, Pico Prism, can complete Ethereum block proofs in an average of 6.9 seconds, with 99.6% of blocks completed within 12 seconds, achieving real-time proof (RTP) for Ethereum for the first time. Currently, Pico ZKVM, as an "on-chain ZK data co-processor," has been applied in various scenarios such as privacy-preserving incentive distribution, high-performance DeFi, and trustless on-chain data computation, providing Rust programming support for developers with zero ZK development experience.Michael predicts that in the next 10 years, 99% of blockchain computing will occur off-chain, verified through ZK proofs. Brevis is driving this process through its verifiable computing infrastructure.

Viewpoint: Tokens should capture on-chain value, while equity should capture off-chain value

The Chief Legal Officer of the cryptocurrency venture capital firm Variant Fund, Jake Chervinsky, stated on social media, "The debate about tokens versus equity is just beginning. Many crypto projects were born during the era of former SEC Chairman Gary Gensler, when strong regulatory pressure forced development companies to direct almost all value towards equity rather than tokens. Now, the policy environment is changing, and new opportunities are emerging. It will take a lot of time and experimentation to figure out how (or if) tokens and equity can work well together. This experimental phase is starting right now.I don't have a specific stance on Aave's situation, but I want to emphasize one point: clarity is always the most important. Token holders must clearly understand what they actually own, what they can control, and what they cannot control. The design space for value capture in tokens is extremely broad, far exceeding that of traditional equity.I believe that for a considerable time, it will be unlikely to form a standardized token model like stocks. We believe that tokens should carry on-chain value, while equity should carry off-chain value. The core innovation unlocked by tokens is self-sovereign ownership of digital property. Tokens allow holders to directly own and control on-chain infrastructure without relying on off-chain intermediaries.Off-chain value, however, is different. Token holders cannot directly own or control off-chain income or assets, so in most cases, this value should belong to equity rather than tokens. Of course, other models may also work. Some projects may choose a single asset model with no equity at all; others may decide to treat their tokens as tokenized securities and apply the new rules that the SEC will establish for this market in the future."
