Good day everyone,
I hope you are all having a good day, welcome to CryptoGod-1's blog on all things crypto. In this post I will be looking at the recent comments by Vitalik Buterin in relation to the need for better privacy in Web3.
Vitalik Buterin Wants Better Web3 Privacy
The co-founder of Ethereum Vitalik Buterin has called for a rethink of privacy data collection as he called for decentralised networks to secure user autonomy in an increasingly exposed digital space. His new article is titled “Why I Support Privacy” and as part of this his has urged those in the Web3 community to treat privacy as a main focus within decentralisation. This comes as concerns continue over AI-driven surveillance and data misuse.
As part of the essay Buterin outlined the philosophical, technical, and social arguments for embedding privacy at the foundation of Web3 design. Some of the bigger issues focus on artificial intelligence and large-scale data harvesting which have been taking away personal autonomy and civil liberties. Buterin went on to explain that his shift toward privacy advocacy has arisen from his own belief that information is power. With this he thinks that if power is centralised then it poses the risk of distorting democratic balance. He stated:
“[A] user only benefits from any decentralization, censorship resistance, security, privacy, or other properties that Ethereum and its applications offer to the extent that the wallet itself also has these properties,”
He went on to note that there are ways to ease transfers among Ethereum’s layer-2 (L2) scaling networks, such as Optimism and Arbitrum. As part of the recent advances in cryptography along with increasingly sophisticated AI systems the fear relating to stronger privacy has become more urgent than ever. Currently Ethereum hosts dozens of L2 scaling networks and collectively they handle more than $50 billion in total value locked.
Buterin emphasised the need for privacy in the ever advancing world and that it is about more than just hiding secrets. He noted it is about maintaining personal agency in systems that are trending toward surveillance by default. As Web3 developers continue to evolve their systems, Buterin feels they must integrate privacy features into all wallets rather than relegating privacy to a handful of specialised wallets. He stated:
“Up until now, making private transfers on Ethereum has required users to explicitly download and use a ‘privacy wallet. This adds great inconvenience and reduces the number of people who are willing to make private transfers. The solution is that private transfers need to be integrated directly into wallets.”
It was emphasised that fully homomorphic encryption, ZK-proofs, and code obfuscation as foundational tools for developers to build privacy-preserving decentralised systems are all options to be considered. Buterin framed privacy as a basic component of freedom in the digital age and referenced the early 2000s where optimism had grown around transparency, such as David Brin’s The Transparent Society and Scott McNealy’s infamous “privacy is dead” comment, and he argued that such views had aged poorly.
The Ethereum co-founder noted that instead of promoting fairness that transparency has increasingly allowed powerful institutions to operate without oversight, while individuals lose control over their own lives. He highlighted an example of when he was filmed in Chiang Mai while using his laptop, and the video was later circulated online. While this might seem common place in the modern world, he noted have it demonstrated how easily personal moments can be captured and spread without consent.
Buterin also warned how this kind of hyper-visibility, once limited to celebrities or public figures, now extends to anyone and especially those vulnerable due to their job, opinions, or unexpected exposure. He also noted that the idea of national security justifying access to private data is not correct. Buterin feels that building backdoors, even for well-intentioned reasons, creates long-term risks of abuse, corruption, and unchecked power. Given the scale of data being collected today it shows that previous generations were under minimal risk compared to the growth of potential for harm in modern society.
On April 11, Buterin released a roadmap outlining how Ethereum could build in stronger privacy protections without modifying its Layer-1 consensus model. The roadmap includes four areas: anonymous payments, privacy at the application level, secure data reads, and obfuscation at the network layer. Buterin also advocated for generating a unique address per dApp to prevent linkability and for supporting standards such as FOCIL and EIP-7701 to reduce reliance on public transaction relays. This reinforced his belief that privacy should be a design principle, not a secondary consideration, when creating resilient Web3 systems.
Have a great day.
Peace. CryptoGod-1.
