largest altcoin ETHAlthough ‘s price has fallen short of expectations through 2025, the network itself hasn’t had a quiet year. The year opened with leadership discussions within the Ethereum Foundation and continued with successive protocol updates, security priorities, and interoperability goals. Pressure from the developer community led the organization to redefine both its management structure and long-term vision. The resulting chart indicated a radical transformation on the protocol side, independent of the price chart.
Restructuring Process Starting with Pectra
In the first months of 2025 Ethereum Foundationfaced criticism that it had lost direction. Calls from the community for “wartime leadership” brought internal discussions to the public, and concrete steps were taken in February. Served as executive director for many years Aya MiyaguchiWith ‘s ascension as president, Vitalik Buterin has vowed to reshuffle the leadership structure. in a short time Hsiao-Wei Wang And Tomasz K. Stańczak was appointed co-executive director. Danny RyanA new narrative and marketing unit called Etherealize was established, headed by . In the spring, the board of directors and R&D structure were simplified, some teams were merged, and layoffs were made to focus on core protocol priorities.
This institutional change was put into effect in May. Pectra updateThus, it found its reward in the technical field. Described as the Prague-Electra combination, the update moved account abstraction to the mainnet with EIP-7702, increased the maximum staking limit for validators to 2,048 ETH, and expanded data blob capacity. UpdateTens of thousands of new authorization transactions were created on the mainnet in the first week after , demonstrating that wallet providers are rapidly adopting smart account flows. The “Trillion Dollar Security” program, launched in the same period, systematically addressed threat surfaces, protocol risks and user experience-related vulnerabilities in line with the goal of becoming a global financial infrastructure.
Scaling, Privacy and Interoperability Improvements on Fusaka Road
With the summer months the focus is on the next big update. fusakaIt shifted to . Vitalik Buterin argued that the PeerDAS data availability scheme, which is at the center of the update, will significantly increase the capacity of Layer-2 networks. In the same period, the “dAI” initiative, which aims to make Ethereum the basic infrastructure for artificial intelligence-based systems, was announced and studies on decentralized artificial intelligence applications were initiated. Parallel interoperability efforts aimed to give the increasingly crowded Layer-2 ecosystem the feeling of a single Blockchain. “Interop Layer” frameworks have been released for cross-rollup messaging and developer experience.
The year also gained momentum on the privacy side. The Foundation shared an end-to-end roadmap covering specific read-write and proof processes, and a dedicated Privacy Cluster team was established for this area. Introduced in the fall, the Kohaku proposal offered a framework for how to support privacy-focused applications without sacrificing auditability and decentralization.
At the end of November, the block gas limit was increased to 60 million. Immediately afterwards, Fusaka was activated and a regular hard fork schedule was started twice a year. As the year drew to a close, the naming of the post-Glamsterdam update in 2026 as “Hegota” clarified the medium-term road map and signaled that the steps taken in Pectra and Fusaka would be made permanent.
