Over the past few years, the narrative in the crypto industry has been dominated by financialization logic. From DeFi and NFTs to MEMEs and ETFs, market attention has increasingly focused on asset prices, liquidity, and institutional capital inflows.
However, recently, the Ethereum official proposed that "privacy is undergoing a renaissance" and reemphasized the "new cypherpunk" philosophy, which represents, in some ways, a return to core values.
Ethereum is reminding the entire industry that the original purpose of blockchain was never merely financial speculation, but rather to safeguard individuals' rights and freedoms in the digital world through cryptographic technology. Privacy, censorship resistance, open source, and security—these principles may seem idealistic, but they are in fact the deepest foundational logic of the crypto industry, and perhaps the true meaning behind Ethereum’s new “cypherpunk” narrative.
I. From Cypherpunks to Ethereum: The Intellectual Origins of the Cryptocurrency Industry
To understand why Ethereum places such a strong emphasis on privacy, we must first return to the original philosophical foundation of the crypto industry—the cypherpunk movement.
In the 1990s, a group of programmers, cryptographers, and internet idealists discussed in mailing lists whether personal privacy could still be protected once the internet became societal infrastructure.
Their answer is: If you rely on governments and corporations, privacy is nearly impossible to guarantee. Therefore, the only solution is to use cryptographic technology.
These individuals are known as "cypherpunks." Their core belief is that individuals can maintain privacy, freedom, and censorship resistance in the digital world through open-source code and cryptographic tools.
In cypherpunk culture, there is a very famous saying:
Privacy is not secrecy; it's about selectively showing yourself to the world.
The creation of Bitcoin was a direct result of cypherpunk ideology. When designing Bitcoin, Satoshi Nakamoto aimed to break free from the control of traditional financial systems through a decentralized network, while giving individuals absolute control over their assets.
Ethereum builds upon this foundation by further expanding it. Unlike Bitcoin’s single-purpose monetary system, Ethereum provides an open platform for running smart contracts, enabling decentralized applications.
However, over the past few years, the cryptocurrency industry has gradually undergone some changes.
As capital flows in and the market scale expands, an increasing number of projects are focusing on financial innovation. Financial tools such as liquidity mining, yield farming, and derivatives trading have rapidly evolved, transforming blockchain into a vast on-chain financial market.
During this process, the industry’s core narrative also shifted. Technological idealism gradually gave way to financial logic, and issues such as privacy and digital rights were marginalized.
Therefore, when Ethereum revisits the "cypherpunk spirit," it is essentially reminding the industry that blockchain is not merely a financial technology—it embodies a value system for digital society.
Two: "New Crypto-Punks": Upgrading the Value System in the Web3 Era
Ethereum's "new cypherpunk" is not a simple return to the 1990s cypherpunk movement, but rather a modernized evolution of it.
Traditional cypherpunks were more of a technological idealism culture, emphasizing personal privacy, encrypted communication, and resistance to government surveillance.
In the Web3 era, this concept has been expanded into a more comprehensive collaborative system.
Ethereum officially summarized a set of keywords: CROPS, which stand for Censorship Resistance, Open Source, Privacy, and Security.
These four principles form the core of the new cypherpunk culture.
First is censorship resistance. On traditional internet platforms, control over content and accounts often rests with the platform companies. Blockchain networks, through their decentralized architecture, allow anyone to participate freely and are difficult for any single entity to shut down or control.
Secondly, it is open source. The vast majority of core technologies in the cryptocurrency industry are open source, meaning anyone can view the code, audit the logic, and contribute to improvements. Open source not only enhances technical transparency but also fosters a globally collaborative development model.
Third is privacy. In the Web2 era, user data is often collected by internet companies and used for commercial purposes, with users having almost no control over how their data is used. The cypherpunk philosophy holds that users should have control over their personal data.
Finally, there is security. Blockchain systems rely on cryptography and decentralized networks to ensure security—a security that comes not from centralized authorities, but from mathematics and consensus mechanisms.
In addition to CROPS, the new crypto-punk movement emphasizes several key principles, such as permissionless access, trustlessness, and decentralized collaboration.
Permissionless means that anyone can deploy applications or conduct transactions on the network without requiring approval from the platform.
Trustlessness reduces reliance on third-party institutions through code and smart contracts. Users do not need to trust a company or organization, but rather the transparent and open logic of the program.
These ideas together form the cultural foundation of Web3.
Therefore, Ethereum's proposal of the "New Cypherpunk" is an attempt to reinvigorate this culture and guide the entire ecosystem back toward a longer-term technological vision.
III. The Privacy Renaissance: Why Now Is the Critical Moment
Ethereum believes that now may be a critical stage for the development of privacy technologies, for multiple reasons.
The maturity of technical conditions is the primary factor. Over the past few years, zero-knowledge proof (ZK) technology has made significant advancements. ZK technology enables users to prove a fact without revealing specific data—for example, proving that a transaction is valid without exposing the transaction amount or addresses.
This technology provides a crucial foundation for private transactions, private identities, and private computation.
Meanwhile, the development of Layer 2 networks has created new opportunities for privacy features. Some emerging networks are beginning to embed privacy functionalities directly into their infrastructure, enabling users to enjoy enhanced data protection by default.
Next come the practical issues brought about by on-chain transparency. Many people new to blockchain assume it is anonymous. In reality, data on most public blockchains is fully visible—once you know an address, you can trace all of its transaction history.
With the advancement of on-chain analysis tools, many institutions have been able to identify the entities behind addresses through data analysis.
This means that if a user holds significant assets on-chain or engages in frequent transactions, their behavior is likely to be tracked over the long term.
Therefore, more and more people are realizing that blockchain requires not only transparency but also **selective privacy**.
Another trend is the rise of digital identities. As the Web3 ecosystem grows, more social relationships, asset information, and on-chain identities are being recorded on the blockchain. If all this data were fully public, it could pose security risks.
For example, some users may not wish to disclose their asset size or trading strategies, as this could lead to targeted attacks.
Therefore, the future of Web3 will likely require a new identity system that can verify users' identities and reputations without exposing excessive personal information.
Zero-knowledge proofs and privacy-preserving computing technologies are essential tools for achieving this goal.
Conclusion: Privacy may be the core narrative of the next phase.
As Ethereum reemphasizes the "new cypherpunk" movement and a privacy renaissance, this is not only a cultural expression but may also signal a shift in industry narratives.
Over the past few years, the focus of the crypto market has primarily been on financial innovation and capital flows. However, as technology evolves and user demands shift, issues such as privacy, digital identity, and data sovereignty may once again become central to the industry. If privacy technologies can be integrated with DeFi, social networks, and digital identity systems, the future shape of Web3 could change significantly.
In this context, the blockchain is no longer just a publicly transparent financial ledger, but a digital infrastructure that ensures security and trust while protecting personal privacy. In a sense, this is precisely the future envisioned by cypherpunks thirty years ago—and today, Ethereum is striving to bring that ideal back to reality.
