Vitalik Buterin Announces Ethereum’s Upcoming Milestones: Verkle Trees and History Expiry

The Ethereum network takes a major leap in scalability with the completion of the “Major Aggregate Scaling” milestone, paving the way for verkle trees and history leaks.

The Ethereum network has reached a critical milestone in its scalability roadmap with the successful implementation of “Basic Aggregate Scaling,” according to a post by Vitalik Buterin on Warpcast. This development is a key component in Ethereum’s transition to a more scalable and efficient blockchain, which is essential to its long-term success and adoption.

What next?

After this milestone, the Ethereum development community turns its sights to integration of verkle trees and the flow of history. Verkle trees are an evolution of Merkle trees that will allow for more efficient and compact proofs, reducing the amount of data validators have to store. History expiration is a concept that will allow old transaction data to be removed, thus reducing “state bloat” and making it easier for users to run full nodes.

Introducing Basic Bulk Scaling

Bundles are solutions that perform transactions outside the Ethereum main chain (Layer 1) and send transaction data back to it. This “Basic Aggregate Scaling” is the foundation that enables increased network throughput while maintaining security by leveraging the main chain for data availability and consensus.

The Verkle Tree Promise

Looking ahead, the Ethereum development team is focusing on the integration of verkle trees. Verkle trees are a proposed upgrade to existing Merkle trees, which are data structures that enable secure and efficient verification of content on a blockchain. Verkle trees will optimize storage and computation efficiency, significantly reducing the size of proofs and making it easier to run an Ethereum node.

Understanding story flow

Another upcoming feature is history exfiltration, a mechanism that will allow the Ethereum network to discard older historical data, thus preventing the data size on the blockchain from growing excessively. This will ease the burden on nodes by ensuring that the storage space requirement does not become a barrier for validators and full node operators, which in turn contributes to the decentralization and resilience of the network.

Community reactions and expectations

The announcement received a positive response from the Ethereum community, with many expressing excitement and support for the progress. Vitalik’s Warpcast update garnered 1,728 reactions and various comments from key players in the Ethereum ecosystem. Brian from @br1an.eth has extended an invitation to discuss the @unlonely platform update, showing strong interest in the implications of this development.

The future of layer 2 scaling solutions

Questions about the timeline for Tier 2 solutions, which adopt new features like blobs, a form of data storage that can further reduce fees, have been raised by community members like Hugo Montenegro (@hmheck). The expectation for more affordable transaction costs was palpable, with users like Pacheco (@pachec0) expressing concern about the current fee structure.


The recent achievement of the Ethereum network in achieving the “Major Aggregate Scaling” milestone has generated enthusiasm among stakeholders and users alike. As the community eagerly awaits the implementation of verkle trees and the release of history, the path to a more scalable and user-friendly Ethereum continues to unfold.
