For years, the roadmap for Ethereum has been defined by expansion, adding layers, scaling throughput, and onboarding the next billion users.
But now, Ethereum’s Co-Founder Vitalik Buterin, is arguing that Ethereum’s long-term survival depends on doing the opposite.
He’s calling this process “protocol simplicity”, or what he describes as “garbage collection” for Ethereum.
Buterin believes that over time, Ethereum has picked up extra code, old design choices, and complex features that are no longer essential.
If these aren’t cleaned up, they slowly make the network harder to understand, harder to maintain and riskier to run.
What’s the core issue?
One of those values is passing the “walkaway test”. That means Ethereum should keep working even if today’s core developers disappear.
New teams should be able to understand the protocol, build new clients, and run the network without needing insider knowledge or trusting a small group of experts.
Additionally, at the core of this idea is a basic truth about decentralization.
A system is not truly trustless or self-sovereign if only a small group of highly specialized experts can understand it.
When users have to blindly trust others to explain how a protocol works, decentralization starts to break down.
Therefore, as Ethereum [ETH] grows older, Buterin wants Ethereum to be the simplest, leanest, and easiest to check.
He envisions a system that skilled developers can understand, rebuild, and trust even decades from now.
But what are the underlying concerns?
Needless to say, at present, many blockchain debates focus on things like transactions per second or how many nodes a network has.
But Buterin argues these numbers don’t matter much if the core code is too complex to understand.
He warns about what he calls a “High Priest” problem.
If a protocol depends on extremely advanced cryptography, then regular developers are forced to trust those experts.
At that point, the system stops being truly self-sovereign.
As Buterin puts it, a protocol isn’t really trustless if users have to rely on a small group of experts to explain what guarantees it actually provides. This also creates a “walkaway” risk.
Cleaning up without breaking the past
However, this “garbage collection” doesn’t mean deleting everything old.
Instead, older features can be moved out of the core protocol and handled in smarter ways.
Account abstraction can allow old transaction types and traditional wallets to be handled by smart contracts instead of the core protocol.
The Ethereum Virtual Machine (EVM) could eventually be replaced by a simpler system.
The EVM wouldn’t disappear.
It could just run as a contract inside the new system. Developers wouldn’t need to support every old Ethereum version forever.
Legacy versions could be kept in isolated environments, while modern clients focus only on the present.
Ethereum growing up
All in all, Buterin sees Ethereum’s first 15 years as a kind of adolescence, a time of fast growth, experiments, and mistakes.
That phase was necessary.
But it can’t last forever.
The next phase is about slowing down, simplifying, and strengthening the foundation.
Concluding his vision, he put it best when he said,
“Basically, we want to improve Ethereum in a way that looks like this:”

All these moves and visions of Buterin show that by 2026, the narrative of Ethereum has changed.
It is no longer just about being a “World Computer” that can do everything.
It is about being a “Hyperstructure” that does the right things securely.
Final Thoughts
- Vitalik Buterin’s push for “protocol simplicity” is a long-term survival strategy, not a short-term upgrade plan.
- True decentralization requires that many developers, not just experts, can understand, verify, and maintain the network.
