Ethereum co-founder Vitalik Buterin discusses the activation of the Dencun hard fork and the impact of blobs on the ecosystem, outlining Ethereum’s long-term scaling roadmap and future direction.
In a recent post on his website, Ethereum co-founder Vitalik Buterin explores the activation of the Dencun hard fork and the introduction of blobs on the Ethereum network. Buterin highlights that this hard fork marks a pivotal moment in Ethereum’s scaling efforts.
Blobs, also known as proto-danksharding or EIP-4844, have significantly reduced transaction fees for rollups. Initially almost free, the utilization of blobs within the blobscriptions protocol has led to a fee market activation. Despite not being completely free, blobs remain much cheaper than calldata.
This milestone represents a shift in Ethereum’s scaling approach from solving a “zero-to-one” problem to a “one-to-N” problem. While further enhancements are planned to increase blob count and optimize rollups’ use of each blob, the core changes to Ethereum’s scaling framework are mostly complete. The focus is now transitioning towards addressing application-layer challenges rather than layer one (L1) concerns like proof-of-stake (PoS) and scaling.
Buterin discusses the future of Ethereum scaling, underscoring the move towards a layer two (L2)-centric ecosystem. Major applications are already shifting from L1 to L2, and payments are increasingly being processed on L2 by default. Wallets are adapting to this multi-L2 environment to enhance user experience.
A key aspect of Ethereum’s rollup-centric roadmap is the concept of separate data availability space (DAS). This dedicated section within a block enables layer two projects like rollups to store data independently from the Ethereum Virtual Machine (EVM). EIP-4844 sets the foundation for implementing data availability sampling (DAS), aiming for significant expansion of blob space to 16 MB per slot.
Looking ahead, Ethereum’s development will focus on increasing blob capacity and enhancing L2 protocols to maximize data space utilization. Buterin suggests the introduction of PeerDAS and the exploration of data compression and optimistic data approaches to boost L2 scalability.
Furthermore, Buterin stresses the importance of addressing execution-related constraints and bolstering security in L2 protocols. Proposed solutions include stricter standards and security councils to enhance the reliability of L2 implementations.
In summary, the activation of the Dencun hard fork and the introduction of blobs mark a significant milestone in Ethereum’s scaling efforts. Buterin’s insights shed light on Ethereum’s future development trajectory, focusing on L2-centric solutions, data availability sampling, and continuous improvement of L2 protocols. These advancements pave the way for a more scalable and secure blockchain platform as the Ethereum ecosystem evolves.
