Ripple has launched Ripple Prime, an institutional brokerage platform, following its $1.25 billion acquisition of Hidden Road completed in October 2025. The platform integrates multi-asset trading, custody, and collateral services with Ripple's payment infrastructure and RLUSD stablecoin. Michael Arrington, founder of Arrington Capital, described the acquisition as Ripple's smartest move to date, citing synergies between Hidden Road's brokerage capabilities and Ripple's blockchain technology.

Japan's 2023 Payment Services Act amendment restricts stablecoin issuance to banks and trust institutions, establishing a conservative regulatory regime. Experts warn the framework's exclusion of global stablecoins like USDC and its inward focus may constrain DeFi innovation compared to Hong Kong and Singapore's more open approaches.

Dogecoin's protocol includes a deliberate 3.49% annual inflation mechanism that experts identify as an intentional design choice rather than a flaw. The fixed issuance model adds approximately 5 billion DOGE annually to the current 151.36 billion circulating supply. This structure promotes network security and long-term sustainability through consistent miner incentives.
