Ethereum (CRYPTO:ETH) co-founder Vitalik Buterin said the blockchain has drifted away from its original cypherpunk ideals over the last 10 years.
Buterin outlined his concerns in a January 16 roadmap presentation that set 2026 as a turning point for the network.
He described the past decade as a period of “backsliding” on decentralisation as Ethereum prioritised scalability and mainstream adoption.
The Ethereum co-founder said compromises made for growth weakened the network’s promise of self-sovereignty for users.
Buterin warned that many Ethereum users now rely heavily on centralised infrastructure to interact with the blockchain.
He pointed to widespread dependence on trusted servers and Remote Procedure Calls, or RPCs, as a structural weakness.
This setup forces users to trust third-party data providers instead of verifying blockchain data independently.
Buterin said this reliance undermines the core principle of permissionless verification.
To address the issue, the 2026 roadmap prioritises technologies such as Helios and Zero-Knowledge Ethereum Virtual Machines.
