Ethereum co-founder Vitalik Buterin said new privacy and data-handling technologies have effectively solved the blockchain’s long-standing scalability challenges.
However, he cautioned that a full security rollout of these developments remains a few years away.

Buterin Outlines 2030 Roadmap to Ensure Full Security
In a January 3 post on X, Buterin said Ethereum’s integration of zero-knowledge virtual machines has changed the network’s capabilities.
He added that the shift is driven by the pairing of ZK-EVMs with the data distribution method, PeerDAS.
He claimed this combination resolves the “Blockchain Trilemma”—the historic engineering difficulty of achieving decentralization, security, and high bandwidth simultaneously.
Buterin compared the upgraded architecture to a “BitTorrent with consensus,” contrasting it with Bitcoin’s model, which prioritizes decentralization but struggles with data throughput.
With the new upgrades, he noted, Ethereum can now handle data loads comparable to massive file-sharing networks while maintaining the security of a decentralized ledger.

However, the roadmap for implementing this vision extends well into the future.
While Buterin asserted that the technology has reached “production-quality performance,” he conceded that significant work remains to ensure the system’s safety.
According to his timeline, ZK-EVMs will not become the primary method for validating blocks until between 2027 and 2030. These systems will enable faster and cheaper transaction verification without exposing underlying data.
In the interim, the network plans to implement incremental upgrades.
This year, Buterin expects the gas limit to increase. New protocol developments would enable this by separating transaction proposers from block builders and expanding the amount of work each block can handle.
Looking further ahead, Buterin outlined a goal for “distributed block building.” This is a system in which no single entity constructs a complete set of transactions.
He said distributing this authority reduces the risk of centralized censorship and ensures transactions are processed more evenly across regions.
The technical pivot comes as Ethereum continues to face stiff competition from faster, lower-cost blockchains, pressuring developers to accelerate the deployment of these next-generation scaling solutions.
