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.

Coinbase reaches a settlement with the U.S. SEC over the Freedom of Information Act lawsuit and promotes reforms in record-keeping policies

According to The Wall Street Journal, Coinbase Chief Legal Officer Paul Grewal stated that Coinbase has reached a settlement with the U.S. Securities and Exchange Commission regarding a Freedom of Information Act lawsuit, with the SEC agreeing to pay $150,000 and amend its record-keeping policies. The lawsuit revealed that the SEC lost nearly a year’s worth of communications from former Chairman Gary Gensler and other senior officials during the peak enforcement period in the cryptocurrency industry.Coinbase had previously requested documents from the SEC regarding how it applies securities laws to digital assets, but the request was denied, leading to a lawsuit that received court support. The SEC claimed that some text messages were lost due to an automatic data deletion process. Grewal pointed out that the SEC has imposed billions of dollars in fines on financial institutions for similar record-keeping issues.In February of this year, Coinbase also reached a settlement with the Federal Deposit Insurance Corporation regarding another Freedom of Information Act lawsuit. Coinbase stated that this lawsuit revealed that the FDIC had instructed nearly twenty banks to suspend cryptocurrency-related activities since 2022, which subsequently led to congressional hearings and resulted in a court ruling that the FDIC violated federal law.Grewal stated that both lawsuits revolve around government transparency and due process, emphasizing that the American public has the right to know whether regulatory agencies are restricting legitimate cryptocurrency businesses from accessing banking services through non-public means.

Anthropic donates another $20 million, doubling AI policy lobbying funds

Artificial intelligence company Anthropic announced on Wednesday that it will make an additional donation of $20 million to the bipartisan advocacy organization Public First Action, bringing its total commitment to $40 million. Anthropic stated that the decision for the additional donation stems from the continuous enhancement of AI model capabilities (including its self-developed Mythos model) and the potential risks it brings.Public First Action is a 501(c)(4) nonprofit organization dedicated to public education on AI transparency and safety. The organization is associated with three super political action committees (super PACs) and plans to support candidates advocating for AI safety across both parties. Anthropic emphasized that the donations are solely for supporting Public First Action's policy mission and cannot be used to influence the election of specific candidates.In a statement, Anthropic noted that AI policy decisions will impact various aspects of public life, including the labor market and national security, and the company hopes to promote "flexible regulation" to manage risks while reaping the benefits of AI. Currently, the super PAC "Leading the Future," which advocates for rapid AI development and light regulation, has received significant funding from supporters including OpenAI co-founder Greg Brockman and venture capital firm a16z. As AI increasingly becomes a topic in elections, public education and lobbying efforts by advocacy groups are continuing to ramp up.

Approximately $200 million in trades on Polymarket in the first half of the year were flagged as potential insider trading

According to Bloomberg, as prediction markets like Polymarket and Kalshi expand, the issue of betting using non-public information or informational advantages is receiving more scrutiny. Bloomberg Businessweek analyzed approximately 34,000 potential insider trading cases flagged by Polysights between August 2025 and June 2026; these related trades exhibited characteristics such as newly created accounts, low probability entries, large bets, or high trading concentration, but it cannot be determined that traders violated rules based on this.Data shows that from January 1 to June 30 of this year, the amount of suspicious trades flagged on Polymarket was approximately $200 million, with geopolitical and war-related markets driving a significant increase in abnormal trading volume. The profits from potential insider trading are highly concentrated, with the top 1% of accounts in profit wallets earning more than half of the gains, and 57% of related wallets created less than 24 hours before the trades. Some traders are reducing the likelihood of being discovered by using multiple associated wallets and splitting orders. For example, 38 associated addresses placed bets in 90 geopolitical markets related to Iran and Venezuela, achieving a win rate of 98%, with total profits of $1.6 million, and withdrew funds using the same Coinbase deposit address.Polymarket stated that it will monitor insider trading and other illegal activities, and has so far referred nearly 100 wallets to law enforcement agencies. Kalshi has also strengthened identity and employment information checks, and restricted participation in related markets by political candidates, athletes, and others who may influence outcomes.

David Sacks: Opposes using regulatory uncertainty to suppress open-source AI, warns that the AI duopoly is seeking to eliminate competition

David Sacks, Chairman of the President's Council of Advisors on Science and Technology, stated on the X platform that using regulatory uncertainty as a competitive tool is "completely unacceptable." Regulatory decisions should be based on facts, logic, and evidence, rather than deliberately creating fear and uncertainty (FUD). He is unsure whether venture capitalist and AI policy researcher Dean Ball is acknowledging a strategy of "regulatory capture" or merely predicting that such a situation will occur. However, in any case, the practice of issuing "soft law" warnings through regulatory agencies to create market panic, thereby forcing regulated companies away from Chinese open-source models, should not be accepted.David Sacks pointed out that Dean Ball believes there is no need to directly ban Chinese open-source models; it is sufficient to guide regulatory agencies to issue relevant warnings, which can influence corporate decision-making by creating enough doubt and uncertainty, and these reasons "do not even need to be very substantial." Any regulatory decision must have sufficient basis, rather than implementing policies by "artificially creating doubt." He warned that this practice of circumventing public deliberation procedures not only undermines the foundation of the rule of law but may also open the door to regulatory abuse against any company or individual in the future.David Sacks further stated that current AI policy is at a critical turning point. Leading closed-source laboratories, which have already formed a duopoly in AI model revenue, are attempting to use government power to eliminate open-source competitors. He called on other companies and developers in Silicon Valley that still support open competition to make clear statements to jointly maintain an open ecosystem in the field of AI.
