Polymarket updates market integrity rules, explicitly prohibiting three types of insider trading behaviors

According to official news, Polymarket announced today that it has updated its DeFi platform and the market integrity rules of its U.S. exchange regulated by the Commodity Futures Trading Commission (CFTC). These rules have been incorporated into the Terms of Use of the DeFi platform and the Polymarket U.S. Rules Manual, further strengthening Polymarket's requirements against insider trading and market manipulation, and reaffirming Polymarket's commitment to maintaining market quality and protecting user rights.The updated rules clarify three core prohibited insider trading behaviors:Trading based on stolen confidential information ------ If a participant possesses confidential information about the outcome or potential outcomes of an underlying event, and using that information would violate a pre-existing trust or confidentiality obligation to others or entities, the participant may not engage in any contract trading.Prohibition on trading based on illegal insider information ------ Participants may not trade based on confidential information provided to them by others if that information was provided by someone who has a prior trust or confidentiality obligation to others, and the participant knows or has reason to know that the person providing that information would themselves be prohibited from trading based on that information.Trading by individuals who can influence the outcome ------ If a participant has the authority or influence sufficient to affect the outcome of the underlying event, they may not engage in any contract trading.

The Ethereum team is testing fast confirmation rules, aiming to reduce the cross-chain bridge waiting time to about 13 seconds

According to Cointelegraph, the Ethereum client team is testing a mechanism called Fast Confirmation Rules (FCR), aimed at compressing the deposit confirmation time from L1 to L2 networks and exchanges to about 13 seconds, reducing it by up to 98% compared to existing solutions. This mechanism was proposed by Ethereum researcher Julian Ma.FCR determines whether a block can be considered confirmed by evaluating the validators' attestations, rather than relying on the traditional block depth counting method. Its operation is based on two premises: that network message propagation is fast enough, and that no single entity holds more than 25% of the staked ETH. Currently, most users rely on canonical bridges to complete asset transfers, which typically require waiting about 13 minutes; some exchanges and L2s have adopted "k-depth" confirmation rules to shorten the wait, but this method lacks formal security guarantees.FCR can be deployed without a hard fork, and nodes can independently enable it without the need for coordination across the entire network. Ethereum co-founder Vitalik Buterin expressed support for this, believing that the mechanism can provide "hard guarantees" for transactions within a single time slot (about 12 seconds) under specific network conditions. However, there are still voices of skepticism in the community, with some users concerned about whether its trust assumptions can hold up under network pressure. Currently, client and API integration work is still ongoing.
