CZ: Left OKCoin early due to inconsistency with its culture and values, only worked there for 8 months

CZ shared his early career experiences with Chamath Palihapitiya on the All-In podcast, including his work at Blockchain.info (now Blockchain.com) and OKCoin, as well as his deep understanding and value choices in the early Bitcoin industry.Joining Blockchain.info: CZ mentioned that the team had only three members at the time, and he served as the Vice President of Technology. The team later expanded to 18 members, but a restructuring by the CFO led to changes in corporate culture, causing several developers, including CZ, to leave voluntarily. He emphasized that he learned about remote work, the concept of paying salaries in Bitcoin, and how to achieve rapid user growth to around 2 million through "guerrilla" marketing (such as a 150-page post on BitcoinTalk.org).Joining OKCoin: After leaving Blockchain.info, He Yi contacted CZ to invite him to join OKCoin, initially offering a 5% equity stake, but BTC China offered 10%, prompting OKCoin to match the offer within three hours. CZ ultimately chose to join OKCoin in Beijing as CTO, taking on greater business responsibilities.Reasons for leaving OKCoin: CZ revealed that the main reason was a mismatch in culture and values. For example, "It mainly comes down to a mismatch in culture and values; there are some practices I cannot agree with. A simple example is: when they hold events or promote fee discounts, the advertisements make it sound like everyone can enjoy it, but in reality, you have to actively apply to receive it, and it doesn't take effect automatically. Details like this made me uncomfortable." CZ decided to leave in early 2015.

Vitalik: The core difficulties of blockchain scalability are computation, data, and state

Vitalik Buterin published an article explaining his layered understanding of blockchain scalability, pointing out that the difficulty of scaling blockchains increases from low to high in terms of computation, data, and state.Vitalik stated that computation is the easiest to scale, which can be achieved through parallelization, introducing "hints" provided by block builders, or replacing extensive computation with proofs such as zero-knowledge proofs. Data scalability is of medium difficulty; if the system requires data availability guarantees, this requirement cannot be avoided, but it can be optimized through data sharding, erasure coding (like PeerDAS), and supporting "graceful degradation," meaning that blocks of a corresponding size can still be generated even when node data capabilities are lower.In contrast, state is the most challenging part to scale. Vitalik pointed out that to validate even a single transaction, nodes require the complete state; even if the state is abstracted as a tree and only the root node is saved, updating that root still relies on the complete state. Although there are methods for state sharding, they typically require significant architectural changes and are not universal solutions.Based on this, Vitalik concluded that if data can replace state without introducing new centralization assumptions, it should be prioritized; similarly, if computation can replace data without introducing new centralization assumptions, it should also be taken seriously.

The Democratic Party is willing to return to the negotiating table, and there is a breakthrough in the Senate Agriculture Committee's discussions on cryptocurrency legislation

After setbacks in negotiations over cryptocurrency market legislation in the Senate Agriculture Committee, a Democratic senator's aide stated that the Democratic side is still willing to return to the negotiating table to push for a bipartisan compromise.The aide revealed that at the beginning of the new year, Democratic members were "caught off guard" during the negotiations, as the Republican side drafted a new version of the bill without sufficient consultation and originally planned to move directly into the markup process in mid-January. In response, the Democratic side hopes to re-engage with the committee chair, Republican Senator John Boozman's team, before a vote this week to strive for a bipartisan consensus.The Senate Agriculture Committee was originally scheduled to hold a markup and voting session on cryptocurrency legislation this Tuesday, but it has been postponed to Thursday due to severe weather in Washington. Meanwhile, some Democratic lawmakers are actively pushing to restart negotiations to reach a bipartisan-approved text before the hearing.The cryptocurrency market structure bill aims to establish a federal regulatory framework for digital assets, including clarifying the regulatory division between the SEC and CFTC, as well as related disclosure requirements. Analysts point out that, given that both the Senate Banking Committee and the Agriculture Committee need to advance their respective versions of the bill, bipartisan cooperation remains a key prerequisite for the smooth progress of the legislation.
