Ethereum co-founder Vitalik Buterin has called on the crypto industry to expand Ethereum’s role beyond financial applications, arguing that the network should support privacy tools, decentralized coordination systems, and other open technologies that are resilient to government or corporate control.
Buterin tweeted Tuesday that Ethereum should be viewed as part of a broader ecosystem, building what he calls “sanctuary technologies,” open systems that allow people to communicate, coordinate, and manage resources without relying on centralized platforms.
“The goal is not to remake the world in Ethereum’s image,” Buterin wrote, referring to visions where finance, governance, and welfare systems all run entirely on blockchain rails. Instead, he argues the aim is to reduce the risk of any single actor gaining total control over digital life.
This opens the possibility of creating “digital islands of stability in a chaotic era,” where Ethereum could help enable “interdependence that cannot be weaponized,” he added.
Buterin also prompted Ethereum developers to “actively build toward a full-stack ecosystem,” spanning wallets and applications as well as deeper layers such as operating systems, hardware, and security infrastructure.
The remarks come as Ethereum developers continue pushing upgrades aimed at improving network capacity and lowering transaction costs, part of a broader effort to scale the platform as usage rises across decentralized finance and other applications.
Corporates and Exchanges Rush to Stake Ethereum Instead of Selling
The ideas put forward fit “squarely” with what the Ethereum foundation and Buterin “have been trying to live by for years,” Trantor, head of Linea-based decentralized exchange Etherex, told Decrypt.
“While it is good to publish thought pieces, manifestos, and other public good statements, there is a very real danger of Ethereum forgetting what it already does and losing focus,” Trantor said.
Strengthening privacy is essential to that vision, Trantor explained.
“When privacy and financial freedoms are guaranteed, the market will develop those applications to meet user and community demand. It does not need to be directed or prioritized from on high,” he said.
Instead, he argued Buterin should remain focused on what he called the core use case of digital assets: building “trusted systems” for decentralized finance. The growth of DeFi, he said, offers a path away from state-controlled financial infrastructure.
While the direction could work, it “must face a harsh reality,” Ryan Yoon, senior analyst at Tiger Research, told Decrypt.
