Ethereum's "New Cypherpunk" Manifesto: A Return to the Privacy Narrative

Author: Climber, CryptoPulseLabs

In recent years, the narrative of the crypto industry has been almost entirely dominated by financialization logic. From DeFi and NFTs to MEME tokens and ETFs, market focus has increasingly centered on asset prices, liquidity, and institutional capital inflows.

However, recently Ethereum officials proposed that “privacy is experiencing a renaissance” and re-emphasized the “cypherpunk” philosophy. To some extent, this marks a return to core values.

Ethereum is reminding the industry that the original purpose of blockchain was not merely financial speculation but to protect individual rights and freedoms in the digital world through cryptographic technology. Principles like privacy, censorship resistance, open source, and security—often seen as idealistic—are actually the fundamental underlying logic of the crypto industry. Perhaps they also underpin Ethereum’s current “cypherpunk” narrative.

1. From Cypherpunk to Ethereum: The ideological roots of the crypto industry

To understand why Ethereum emphasizes privacy so strongly, we must first revisit the initial ideological starting point of the crypto movement—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 a societal infrastructure.

Their answer was: relying on governments and corporations makes privacy nearly impossible to guarantee. The only solution was to use cryptographic technology.

This group was known as “Cypherpunks.” Their core idea was that open-source code and cryptographic tools could enable individuals to maintain privacy, freedom, and resistance to censorship in the digital realm.

A famous quote from cypherpunk culture is:

“Privacy is not secrecy, but the right to control what you reveal.”

The birth of Bitcoin was a direct product of cypherpunk ideals. Satoshi Nakamoto designed Bitcoin to escape traditional financial control via a decentralized network, giving individuals absolute control over their assets.

Building on this foundation, Ethereum further expanded. Unlike Bitcoin’s single-purpose monetary system, Ethereum offers an open platform capable of running smart contracts, enabling decentralized applications.

However, over the past few years, the crypto industry has undergone some changes.

With capital influx and market expansion, more projects have focused on financial innovation. Liquidity mining, yield farming, derivatives trading, and other financial tools have rapidly developed, turning blockchain into a vast on-chain financial market.

During this process, the core narrative has shifted. Technical idealism has gradually been replaced by financial logic, and topics like privacy and digital rights have been marginalized.

Thus, when Ethereum reaffirms the “cypherpunk spirit,” it is essentially a reminder: blockchain is not just a financial technology but also a set of values about digital society.

2. “New Cypherpunks”: Upgrading the value system in the Web3 era

Ethereum’s concept of “New Cypherpunks” is not simply a nostalgic return to the 1990s cypherpunk movement but a modern upgrade.

Traditional cypherpunks leaned more toward technological idealism, emphasizing personal privacy, encrypted communication, and resistance to government surveillance.

In the Web3 era, this philosophy has been expanded into a more comprehensive collaborative system.

Ethereum’s official summary includes a set of keywords: CROPS, representing 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, content and account control often rest with platform companies. Blockchain networks, through decentralized architecture, allow anyone to participate freely and are difficult to shut down or control by a single entity.

Second is open source. Most core cryptographic technologies are open source, meaning anyone can review code, audit logic, and contribute improvements. Open source enhances transparency and fosters a global collaborative development model.

Third is privacy. In Web2, user data is often collected and used commercially by internet companies, with users having little control over data flow. Cypherpunk philosophy advocates that users should have control over their personal data.

Finally, security. Blockchain systems rely on cryptography and distributed networks to ensure security. This security does not come from centralized institutions but from mathematics and consensus mechanisms.

Beyond CROPS, the new cypherpunk also emphasizes principles like permissionless, trustless, and decentralized collaboration.

Permissionless means anyone can deploy applications or conduct transactions on the network without platform approval.

Trustless refers to reducing reliance on third parties through code and smart contracts. Users do not need to trust a company or institution but trust transparent, open logic.

These principles collectively form the cultural foundation of Web3.

Therefore, Ethereum’s “New Cypherpunks” is an effort to reinforce this culture and steer the ecosystem back toward a longer-term technological vision.

3. Privacy renaissance: Why now is a critical moment

Ethereum believes that now may be a pivotal stage for privacy technology development, for several reasons.

First is technological maturity. In recent years, zero-knowledge proof (ZK) technology has made significant progress. ZK allows users to prove the validity of a fact without revealing specific data—for example, proving a transaction is legitimate without exposing amounts or addresses.

This technology provides a crucial foundation for privacy transactions, privacy identities, and privacy computing.

Simultaneously, Layer 2 solutions have opened new space for privacy features. Some new networks are embedding privacy directly into their infrastructure, enabling users to enjoy higher data protection by default.

Another issue is the transparency of on-chain data. Many newcomers believe blockchain is anonymous, but in reality, most public chains’ data is fully open. Knowing an address allows tracking all its transaction history.

With the development of on-chain analytics tools, many institutions can identify entities behind addresses through data analysis.

This means that if users hold large assets or frequently transact on-chain, their behavior can be tracked over time.

Consequently, more people are realizing that blockchain needs not only transparency but also selectable privacy.

Additionally, the rise of digital identities is significant. As Web3 ecosystems grow, more social relationships, asset information, and on-chain identities are recorded on the blockchain. If all this data is fully public, it could pose security risks.

For example, some users may not want to disclose their asset sizes or trading strategies, as this could lead to targeted attacks.

Therefore, future Web3 likely requires a new identity system—one that can prove user identity and reputation without revealing excessive personal information.

Zero-knowledge proofs and privacy computing are key tools to achieve this.

Conclusion: Privacy may be the next core narrative

When Ethereum re-emphasizes the “New Cypherpunks” and privacy renaissance, it is not just a cultural statement but also a potential signal of a narrative shift in the industry.

Over the past few years, the crypto market’s focus has been mainly on financial innovation and capital flows. But as technology advances and user demands evolve, topics like privacy, digital identity, and data sovereignty may regain prominence.

If privacy tech can be integrated with DeFi, social networks, and digital identity systems, the future shape of Web3 could change significantly.

In such a scenario, blockchain would no longer be just a transparent financial ledger but a secure, trustworthy, and privacy-preserving digital infrastructure. In a sense, this aligns with what cypherpunks envisioned thirty years ago. Today, Ethereum is attempting to bring that ideal back into reality.
