Ethereum, co-founder Vitalik Buterin, stated on Friday that 2026 will mark the year when Ethereum will reverse a decade of 'regression' in terms of self-sovereignty and lack of trust, which has occurred while pursuing mainstream adoption.

'Every compromise of values that Ethereum has made so far – every moment where you might have said: is it really worth diluting ourselves so much in the name of mainstream adoption – we are no longer making that compromise,' wrote Buterin in a post on X.

This statement marks a refocusing on privacy, decentralization, and user autonomy in Ethereum's development roadmap, after years of gradual centralization related to reliance on intermediary services.

What went wrong

Buterin acknowledged that nodes have become more difficult to run, that decentralized applications have evolved into data-hungry behemoths, and that wallets increasingly route information through centralized RPC (Remote Procedure Call) providers rather than allowing users to verify data locally.

Block building has also become increasingly concentrated in the hands of a small number of operators, weakening Ethereum's censorship resistance and placing transaction inclusion under centralized control.

The lightweight Helios client allows users to verify blockchain data locally without running full nodes, while cryptographic techniques like Oblivious RAM and Private Information Retrieval prevent monitoring when accessing decentralized applications.

Ongoing technical solutions

Zero-knowledge Ethereum Virtual Machine implementations and blob-anchored logs will simplify the local operation of nodes, according to Buterin's roadmap, while upcoming upgrades aim for seamless private payments providing a user experience comparable to public transactions.

The Ethereum Foundation launched the Kohaku wallet framework in late 2025 as an open-source toolkit dedicated to privacy, while refocusing its Privacy Cluster of 47 members on the goal of making privacy a first-class property of the network.

Social recovery wallets have gained popularity following the introduction of EIP-7702 in Ethereum's Pectra upgrade last year, with Buterin advocating for such solutions since at least 2021 to protect users who lose their recovery phrase, without introducing corporate backdoors.

Network improvement proposals, including ERC-4337 for account abstraction and FOCIL for censorship resistance, will be deployed over the coming hard forks like Glamsterdam, although Buterin has warned that the transformation "will be a long road" that extends beyond several protocol upgrades.
