Vitalik: Re-examining the "Cottage in the Woods" concept, ZK technology changes the trade-off logic of blockchain

Vitalik Buterin recently stated that he no longer fully agrees with the old view of blockchain as "only recording transaction order, not committing to state," and explained the reasons for his change in perspective.Vitalik pointed out that his early opposition to this idea was primarily based on the fact that if the chain does not commit to state, ordinary users must either fully verify all transactions from the genesis block or be forced to trust a single third-party service provider, both of which are not ideal options. In contrast, designs like Ethereum that commit to the state root in the block header allow for the verification of any state through Merkle proofs under the "majority honest" consensus assumption, which is much more feasible. He emphasized that the real game changer is the development of zero-knowledge technologies like ZK-SNARKs, which make it possible to verify the correctness on-chain without re-executing all transactions, thus "achieving both security and scalability."Additionally, Vitalik reflected on the uncertainties in the real world: network interruptions, service provider shutdowns, consensus centralization, and censorship risks can occur at any time. Therefore, the blockchain system must always retain a fallback that is "self-verifiable without relying on others." In his view, the "cabin in the woods" is not a model for everyone to live in daily, but rather a safety net in extreme situations, and it is also an important leverage against intermediaries and service providers. Maintaining such a minimally viable and autonomously usable path is an indispensable part of Ethereum's long-term evolution.

Cathie Wood: The U.S. government may "directly buy" Bitcoin to enrich the national strategic reserves

ARK Invest founder Cathie Wood stated that the U.S. government may begin to directly purchase Bitcoin in the future to bolster the national Bitcoin strategic reserve, rather than solely relying on assets seized by law enforcement.In a recent episode of the "Bitcoin Brainstorm" podcast, Wood pointed out that although the Trump administration established a national Bitcoin reserve through an executive order, the source of the reserve so far has been limited to seized BTC, with no market purchases made to date. The initial goal was to hold 1 million Bitcoins, so I believe they will eventually start buying.She believes that Trump will continue to place a high emphasis on cryptocurrency issues under pressure from the midterm elections, which is favorable for the Bitcoin strategic reserve. On one hand, Trump and his family have deepening interests in the crypto industry; on the other hand, the crypto community played a significant role in his winning the presidential election. She said, "He doesn't want to be a lame-duck president; he wants one or two more productive years in office, and he sees crypto as a path to the future."Reports indicate that the Trump administration has signed multiple executive orders to establish a Bitcoin reserve and a crypto asset inventory, and has formed a crypto and AI task force led by David Sacks to promote industry legislation, including the GENIUS Act (stablecoin legislation).
