pol

PoL (Proof of Liquidity) is a consensus mechanism designed to validate transactions through the provision of liquidity. Unlike traditional Proof of Work (PoW) or Proof of Stake (PoS), PoL rewards participants with block rewards for providing liquidity. This mechanism is commonly used in decentralized exchanges (DEX) or liquidity pools to incentivize users to provide liquidity, thereby enhancing market efficiency and stability. The advantage of PoL lies in its ability to encourage more liquidity providers to participate, strengthening market depth and trading liquidity.

The U.S. CFTC has added 3 new insider trading investigations into Polymarket: involving Biden's pardons, the Iran war, and Google

The U.S. Commodity Futures Trading Commission (CFTC) has previously secretly approved at least three insider trading investigations related to Polymarket trading, involving contracts related to Biden's pardons, the Iran war, and Google-related events. The relevant investigation documents were obtained by WIRED through the Freedom of Information Act.Among them, CFTC Chairman Michael Selig approved an investigation into contracts related to Biden's pardons in May, after a trader had profited over $300,000 in the relevant market; in the same month, the CFTC also approved an investigation into Iran war contracts, after a group of suspicious accounts was reported to have profited $2.4 million with a win rate of about 98%. In July, the CFTC further initiated an investigation into Google-related Polymarket contracts, focusing on individuals who may have traded using non-public information regarding Google's 2025 search rankings. The Southern District Attorney's Office in New York is also conducting a parallel investigation.It is currently unclear whether the aforementioned accounts are connected to previously investigated individuals. Polymarket stated that the company would refer the relevant matters to law enforcement and cooperate with the investigation. As the prediction market rapidly expands, U.S. regulators are clearly intensifying their scrutiny of insider trading and market manipulation.

White House advisors held up to 5 million dollars in Coinbase shares during the advancement of cryptocurrency policy

According to a report by CNBC citing the latest financial disclosure documents, Kevin Hassett, the Director of the National Economic Council (NEC) at the White House, holds between $1 million and $5 million in Coinbase stock as of the end of 2025. Previously, Hassett served as an advisor to Coinbase from 2021 until January 2025, before joining the White House. Since the disclosure documents only cover holdings up to the end of 2025, it cannot be confirmed whether he still holds these shares.This investment has raised concerns because the NEC plays an important role in the cryptocurrency agenda of the Trump administration. Three days after Trump returned to the White House, a digital asset market working group was established within the NEC, responsible for developing regulatory, banking, stablecoin, and tax proposals for cryptocurrencies. Hassett stated that he has avoided cryptocurrency-related matters after consulting with government ethics officials, and the White House claimed he "has always and continues to fully comply with all ethical requirements." However, former SEC ethics lawyer Kantor pointed out that this holding constitutes a "significant conflict of interest" or at least presents the appearance of a conflict. Coinbase spent millions of dollars in the 2024 U.S. elections, and its CEO maintains direct contact with Trump and senior officials.
