- Vitalik Buterin discusses Ethereum’s Purge initiative, emphasizing simplification and resource optimization through proposals like EIP-6780 and EIP-4444.
- Addressing technical complexities, data storage challenges, and the transition to SimpleSerialize (SSZ) are central to Buterin’s vision for Ethereum’s future scalability and decentralization.
Vitalik Buterin – the co-founder of Ethereum – shared insights on the next steps in the protocol’s simplification and easing the burden on node resources, also known as ‘Purge.’
The Purge essentially aims to safeguard the protocol by optimizing data storage. At the same time, it also seeks to address design decisions that were made due to technology constraints in the past. The primary objective is to streamline the protocol, eliminate technical obligations, and reduce participation costs in the network by clearing outdated historical data.
EIP-6780’s Role in Purge
EIP-6780 is a crucial proposal before Ethereum reaches the Purge. It focuses on reducing the functionality of the SELFDESTRUCT opcode within the protocol. The proposal was implemented during the Dencun hard fork in a bid to simplify Ethereum and enhance its security guarantees.
Buterin stressed the importance of this process in removing unnecessary complexity as well as addressing technical debt. This is not only expected to streamline Ethereum’s functionality but also address any accumulated technical issues. EIP-6780 serves as an example of this goal.
Optimizing Data Storage
While Dencun also paved the way for ‘blobs,’ Buterin is also eyeing another crucial proposal to hit the floor, the EIP-4444, which seeks to prune the historical data in clients older than one year. The Ethereum co-founder highlighted the challenge of storing old history for the second-largest blockchain. While entities like block explorers may handle it, he suggests optimizing peer-to-peer protocols to store and share this data, offering a viable solution.
Expanding Participation and Decentralization
According to Buterin, reducing the amount of storage needed to run an Ethereum node can greatly expand participation. Also, EIP-4444 reduces node sync time, streamlining workflows for operators and potentially enhancing Ethereum’s decentralization.
“Hence, EIP-4444 can greatly increase Ethereum’s node decentralization. Potentially, if each node stores small percentages of the history by default, we could even have roughly as many copies of each specific piece of history being stored across the network as we do today.”
Addressing Technical Challenges
Buterin also addressed underused Precompiles, suggesting their removal or replacement with more efficient alternatives. Similarly, he proposed reforms in LOG structures, emphasizing the use of ZK-SNARKs and incrementally verifiable computation (IVC) for constructing verified log trees.
Transition to SimpleSerialize (SSZ)
Another aspect that warrants attention is the ongoing transition of Ethereum to SimpleSerialize (SSZ). While the Ethereum consensus layer has moved to the “cleaner” and more “efficient” SSZ, the same cannot be said for the execution layer, which needs to be moved over to the same structure.
After transitioning to SSZ, only two structures will remain: SHA256 binary trees and Verkle trees. Eventually, as SNARK hashing improves, Buterin noted that both may be replaced by binary Merkle trees using SNARK-friendly hashes, unifying Ethereum’s data structures.
Vitalik Buterin’s emphasis on simplifying Ethereum’s protocol and optimizing its functionalities reflects a commitment to sustainability and scalability. With proposals like EIP-6780 and EIP-4444, Ethereum is poised to undergo significant transformations that could bolster its decentralization and accessibility while maintaining its integrity and security. As the Ethereum community moves forward, these crucial aspects outlined by Buterin will likely play a pivotal role in shaping the future of the platform.
