In a series of posts on X, Blockstream co-founder and cypherpunk Adam Back argued that quantum computing is still at a very early stage and unlikely to threaten Bitcoin for several decades. Venture investor Nic Carter and Bitcoin Policy Institute fellow Craig Warmke countered that dismissive attitudes among key developers toward quantum risk are already weighing on Bitcoin's price and slowing capital inflows. They contend that investors are concerned, large holders are diversifying, and the ecosystem should develop contingency plans to reassure the market.

Vitalik Buterin argues that Ethereum must simplify its protocol so more people can fully understand how the blockchain works, which he views as key to genuine trustlessness. He says Ethereum should sometimes sacrifice features to make the system clearer, while projects like privacy-focused layer 2 INTMAX echo that complex designs merely shift who users must trust. Ethereum’s roadmap already targets easier node operation, smart contract wallets and a Web2-like user experience to lower barriers for everyday users.

Capriole founder Charles Edwards warned that Bitcoin's price could sink to below $50,000 if the network has not implemented quantum-resistant safeguards by 2028. He argued that quantum computers may threaten Bitcoin earlier than many expect and called for a protocol fix to be rolled out in 2026 to avoid what he described as a severe bear market. Other Bitcoin proponents have suggested interim security practices, while some bulls continue to play down quantum-related risks.

Ripple Labs is piloting its US dollar-backed stablecoin RLUSD on Ethereum layer-2 networks Optimism, Base, Ink, and Unichain, after first launching the token on the XRP Ledger and Ethereum in 2024. The pilot uses Wormhole's Native Token Transfers standard so RLUSD can move between chains as a native token rather than as a wrapped version, while a broader rollout and additional chains are planned for next year pending regulatory approval. RLUSD, issued under a New York Department of Financial Services Trust Company Charter, currently has a market capitalization of $1.3 billion.

United States President Donald Trump said at a White House press conference on Monday that he would review the case of Samourai Wallet developer Keonne Rodriguez, who was sentenced in November to prison over his role in the crypto mixing protocol. Rodriguez and co-founder William Lonergan Hill received five and four-year sentences after pleading guilty to operating an illegal money-transmitting business, and supporters are now campaigning for a presidential pardon as conventional appeal options appear limited.
