Michael Saylor: The biggest challenge for Bitcoin's future is not external competition, but the internal erosion of consensus rules

Strategy founder Michael Saylor stated that Bitcoin has gained market recognition, but the biggest challenge in the future is not external competition, but rather the erosion of consensus rules from within. He believes that Bitcoin's consensus rules are like a "constitution," determining property rights, scarcity, settlement mechanisms, and boundaries of power. Any modification of the rules for the benefit of specific groups is an infringement on the economic rights of all participants.He warned that Bitcoin is expected to grow a hundredfold in the future and become the infrastructure of the global capital market, while a single erroneous rule modification could harm markets, technologies, and economic freedoms that have yet to be born. Saylor specifically pointed out certain proposals, including BIP-110, arguing that they undermine the neutrality of the Bitcoin protocol by limiting effective paid transactions, introducing contract mechanisms, or expanding block capacity. He stated that although these proposals take different forms, they all weaken the scarcity of block space, increase network bandwidth and verification costs, expand protocol complexity, and introduce new security risks. At the same time, weakening the fee market will affect miners' income sources after block rewards continue to halve, thereby undermining the long-term security of the Bitcoin network. Furthermore, once a particular interest group is able to modify Bitcoin rules through certain means, other interest groups will follow suit, leading to long-term conflicts in protocol governance, capital outflows, slowed innovation, and deteriorating network security. Saylor called for keeping the Bitcoin base layer simple, neutral, scarce, and secure, leaving innovation to the second layer and application layer, promoting development through voluntary adoption rather than frequent modifications of the underlying protocol, and emphasized that protocol upgrades should be approached with extreme caution and only advanced when truly necessary to maintain the foundation for Bitcoin's long-term development.

Vitalik: The Diamond iO exploration program "stealth" new paradigm may drive privacy computing into a new stage

Ethereum co-founder Vitalik Buterin published a new article introducing a novel cryptographic obfuscation technology called Diamond iO. This technology aims to address the extremely low efficiency of traditional indistinguishable obfuscation schemes, allowing programs to run while hiding internal logic and critical data. Although traditional iO technology possesses strong privacy protection capabilities, its operational costs are prohibitively high, making it nearly impractical. Diamond iO, by adopting more aggressive new cryptographic assumptions, enhances computational efficiency from "universe-level time consumption" to "planet-level time consumption," bringing it closer to practical application.Diamond iO is built on technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). By encrypting programs, it allows users to execute the encrypted programs and obtain correct outputs without being able to view the internal code or hidden keys. This solution introduces a new input encoding mechanism and conditional decryption method, reducing computational complexity while ensuring the program logic remains hidden. Its core application scenarios include protecting programs that contain private keys, enabling secure software licensing, constructing trustless cryptographic services, and supporting blockchain and artificial intelligence systems with stronger privacy protection.However, Diamond iO is still in the early research stage, and its security relies on new cryptographic assumptions, including All-Product LWE and Evasive LWE, which require further research validation. At the same time, the technology still faces efficiency challenges such as high computational overhead and circuit depth limitations. Researchers believe that by optimizing underlying hash functions, improving homomorphic encryption schemes, and reducing security parameter requirements, Diamond iO is expected to become an important direction for advancing practical program obfuscation technology in the future.
