In response to the launch of Open USD (OUSD), a new dollar-backed stablecoin supported by 140 global enterprises, Circle CEO Jeremy Allaire published a detailed rebuttal asserting that the stablecoin market follows a winner-takes-all dynamic. He argued that USDC's decade-long investments in application integration, liquidity network effects, and global regulatory compliance have created an insurmountable moat. Allaire dismissed OUSD's promises of free minting/redemption, revenue sharing, and open consortium governance as unrealistic and detrimental to infrastructure efficiency. Citing data from Artemis, he noted that USDC processed nearly $30 trillion in on-chain transactions in Q1 2026, accounting for 80% of all dollar-denominated stablecoin volumes, while all other dollar stablecoins combined accounted for less than 0.5%. He also emphasized Circle's expanding product suite—Arc, CCTP, StableFX, and Agent Stack—and welcomed OUSD as a new community member.

According to a South China Morning Post report, researchers from the Wenzhou Public Security Bureau and the Zhejiang Provincial Public Security Department published a technical paper on June 4 in the journal Criminal Technology. The paper systematically reveals the forensic tools and case-handling procedures used by Chinese police for virtual currency assets such as Bitcoin and Ethereum. Key methods include tracking transactions via fee analysis to trace exchanges like Binance, obtaining KYC records from exchanges (Binance, OKX, HTX), freezing accounts for up to six months (with possible extensions), and strict rules preventing investigators from holding private keys. The paper demonstrates the high level of professionalism in China's on-chain tracking and anti-money laundering efforts, offering significant insights for crypto compliance and privacy protection.

On July 1, Circle CEO Jeremy Allaire published a detailed rebuttal to the announcement of OUSD, a new stablecoin backed by 140 enterprises. He argued that stablecoin networks exhibit winner-take-all dynamics, with USDC already commanding 80% of on-chain USD stablecoin transaction volume ($30 trillion in Q1 2026) after nearly a decade of building application integrations, global liquidity, and regulatory compliance. Allaire dismissed OUSD's claims of free minting/redeeming, yield sharing, and alliance governance as unrealistic, warning that alliance models typically fail to achieve scale or product-market fit.
