The post Coinbase Slams ‘Patchwork’ State Crypto Laws, Calls for Federal Preemption appeared on BitcoinEthereumNews.com. In brief Coinbase has filed a letter with the DOJ urging federal preemption of state crypto laws, citing Oregon’s securities suit, New York’s ETH stance, and staking bans. Chief Legal Officer Paul Grewal called state actions “government run amok,” warning that patchwork enforcement “slows innovation and harms consumers.” A legal expert told Decrypt that states risk violating interstate commerce rules and due process, and DOJ support for preemption may mark a potential turning point. Coinbase has gone on the offensive against state regulators, petitioning the Department of Justice that a patchwork of lawsuits and licensing schemes is tearing America’s crypto market apart. “When Oregon can sue us for services that are legal under federal law, something’s broken,” Chief Legal Officer Paul Grewal tweeted on Tuesday. “This isn’t federalism—this is government run amok.” When Oregon can sue us for services that are legal under federal law, something’s broken. This isn’t federalism–this is government run amok. We just sent a letter to @TheJusticeDept urging federal action on crypto market structure to remedy this. 1/3 — paulgrewal.eth (@iampaulgrewal) September 16, 2025 Coinbase’s filing says that states are “expansively interpreting their securities laws in ways that undermine federal law” and violate the dormant Commerce Clause by projecting regulatory preferences beyond state borders. “The current patchwork of state laws isn’t just inefficient – it slows innovation and harms consumers” and demands “federal action on crypto market structure,” Grewal said.  States vs. Coinbase It pointed to Oregon’s securities lawsuit against the exchange, New York’s bid to classify Ethereum as a security, and cease-and-desist orders on staking as proof that rogue states are trying to resurrect the SEC’s discredited “regulation by enforcement” playbook. Oregon Attorney General Dan Rayfield sued Coinbase in April for promoting unregistered securities, and in July asked a federal judge to return the…

The post Vitalik Buterin lays out new Ethereum roadmap at EDCON appeared on BitcoinEthereumNews.com. At EDCON 2025 in Osaka, Ethereum co-founder Vitalik Buterin delivered fresh details of Ethereum’s technical roadmap, delineating both short-term scaling goals and longer-term protocol transformations. The immediate priority, according to slides from the presentation, is scaling at the L1 level by raising the gas limit while maintaining decentralization. Tools such as block-level access lists, ZK-EVMs, gas repricing, and slot optimization were highlighted as means to improve throughput and efficiency. A central theme of the presentation was privacy, divided into protections for on-chain “writes” (transactions, voting, DeFi operations) and “reads” (retrieving blockchain state). Write privacy could be achieved through client-side zero-knowledge proofs, encrypted voting, and mixnet-based transaction relays. Read privacy efforts include trusted execution environments, private information retrieval techniques, dummy queries to obscure access patterns, and partial state nodes that reveal only necessary data. These measures aim to reduce information leakage across both ends of user interaction. In the medium term, Ethereum’s focus shifts to cross-Layer-2 interoperability. Vitalik described trustless L2 asset transfers, proof aggregation, and faster settlement mechanisms as key milestones toward a seamless rollup ecosystem. Faster slots and stronger finality, supported by techniques like erasure coding and three-stage finalization (3SF), are also in scope to enhance responsiveness and security. The roadmap also includes Stage 2 rollup advancements to strengthen verification efficiency, alongside a call for broader community participation to help build and maintain these improvements. The long-term “Lean Ethereum” blueprint emphasizes security, simplicity and optimization, with ambitions for quantum-resistant cryptography, formal verification of the protocol, and adoption of ideal primitives for hashing, signatures, and zero-knowledge proofs. Buterin stressed that these improvements are not just for scalability but to make Ethereum a stable, trustworthy foundation for the broader decentralized ecosystem. This is a developing story.
