a16z partner: Still坚持长期主义 in crypto investments, believing that after the popularization of blockchain finance, other categories of apps will emerge

a16z partner and a16z crypto leader Chris Dixon published an article on social media titled "The Long Game of Cryptocurrency," stating: There is a popular saying that the non-financial use cases of cryptocurrency are dead. Some also claim that the "read-write-own" model has failed. These conclusions misunderstand the core concepts and misjudge the stage of development we are in.We are currently in the financial era of blockchain. But the core idea has never been that all crypto applications will emerge simultaneously, nor that finance will not lead the way. The core thought has always been that blockchain introduces a new primitive—capable of coordinating human and capital at internet scale, embedding ownership directly into the system. Finance is the domain where this primitive can most naturally prove its value, which is why we often cite finance as the primary example of productive use cases for tokens.Finance is not separate from a larger vision; it is part of it. It serves as the foundation and testing ground for all other applications. At a16z and a16z crypto, we are looking long-term: our fund structure is designed for a cycle of over 10 years because building new industries takes time—operational sequence is crucial. Infrastructure and distribution networks often emerge before new categories of applications.The internet did not begin with social media, streaming, or online communities; it began with packet switching, TCP/IP, and basic connectivity. Only after hundreds of millions of people went online did entirely new cultural and economic categories emerge. Cryptocurrency is likely to be similar. A reasonable speculation is that we need to onboard hundreds of millions of people through financial applications like payments, stablecoins, savings, and DeFi before we can see meaningful adoption in media, gaming, AI, or other potentially more distant fields.Many applications rely on ready wallets, identities, liquidity, and trust mechanisms. This is why a16z has spent over five years working to establish a clear regulatory framework for tokens. Great endeavors take time. The breakthroughs we see today in the AI field are the result of decades of hard work by outstanding talents. Building a new technological system is a marathon, and this is what a marathon looks like in practice: a long period of groundwork followed by a sharp turning point. It is those chaotic years that make the clarity of the future possible.

a16z stated: Blockchain is the key infrastructure for trust in the internet during the AI era

The a16z crypto team pointed out that as AI systems scale, the internet lacks a native way to distinguish between humans and machines, and the trust system faces challenges. Blockchain technology can provide solutions. The article summarizes the following five key roles:Increase the cost of AI impersonation: By using decentralized human verification systems (such as World ID), the scale of false identity generation is limited, raising the cost of attacks.Decentralized identity verification: Blockchain gives users control over their own identities, avoiding single points of failure in centralized identity systems while protecting privacy and resisting censorship.Create a universal "passport": A blockchain-based identity layer allows AI agents to operate across platforms, carrying permissions and payment information, enhancing interoperability and preventing lock-in effects.Support machine-scale payments: Utilizing blockchain micropayments and smart contracts enables low-cost, granular payment distribution, supporting economic activities between machines.Enhance privacy protection: Through zero-knowledge proofs, users can verify their identity without exposing specific data, preventing AI from misusing information for impersonation.a16z believes that blockchain is a necessary infrastructure for building an AI-native internet, capable of restoring trust and supporting the healthy development of AI systems.

a16z Crypto: The security focus of public chains like BTC and ETH should be on protocols and governance, without blindly switching to quantum-resistant solutions

a16z Crypto published a long article on platform X stating that the timeline for the emergence of quantum computers capable of breaking cryptocurrencies (CRQC) is often exaggerated, and the likelihood of their appearance before 2030 is extremely low. The risk status of different cryptographic primitives varies.Post-quantum encryption needs to be deployed immediately due to the "harvest now, decrypt later" (HNDL) attack. In contrast, post-quantum signatures and zkSNARKs are less susceptible to HNDL attacks; migrating too early could bring risks such as performance overhead, immature implementation, and code vulnerabilities. Therefore, a cautious rather than hasty migration strategy should be adopted.For blockchains, most non-privacy public chains like Bitcoin and Ethereum primarily use digital signatures for transaction authorization, so there is no HNDL risk. The pressure to migrate mainly comes from non-technical challenges such as slow governance, social coordination, and technical logistics.Bitcoin faces unique issues, including its slow governance speed and the existence of millions of quantum-vulnerable tokens worth hundreds of billions of dollars that may be abandoned. In contrast, privacy chains, due to their encryption or concealment of transaction details, do face HNDL attack risks and should transition as soon as possible.a16z Crypto emphasizes that in the coming years, implementation security issues such as code vulnerabilities, side-channel attacks, and fault injection attacks are more urgent and significant security risks compared to the distant threat of quantum computers. Developers should prioritize investment in code audits, fuzz testing, and formal verification.
