Ethereum's Next Upgrade 'The Verge' To Enhance Security And Accessibility

According to Cointelegraph, Ethereum co-founder Vitalik Buterin has outlined plans for the network’s upcoming upgrade, known as 'The Verge.' This update aims to enhance Ethereum's security and accessibility, enabling nodes to operate on devices as small as a phone or smartwatch. The Verge seeks to reduce hardware requirements through 'stateless verification,' allowing nodes to verify blockchain blocks without storing large amounts of data. One of Ethereum’s growing challenges is the increasing data size needed to operate a node, currently requiring hundreds of gigabytes of state data, as noted by research from Paradigm. Stateless verification will make fully verifying the chain computationally affordable, so that every mobile wallet, browser wallet, and even smartwatch can do it by default. This shift means Ethereum nodes will no longer need to store the entire blockchain, lowering technical barriers for users, including solo stakers. In his blog post, Buterin explained that The Verge initially focused on implementing Verkle trees, a cryptographic structure designed to reduce proof sizes and enable stateless validation. However, he acknowledged concerns about Verkle tree vulnerability to quantum computing. Developers are considering Scalable Transparent Arguments of Knowledge (STARK)-based binary hash trees, which offer a better long-term outlook for security and scalability against quantum threats. The Verge also proposes changes to the network’s gas cost system under Ethereum Improvement Proposal (EIP)-4762 in preparation for stateless verification. This change would adjust gas fees for resource-heavy cryptographic operations to ensure network scalability and security while incorporating what Buterin calls 'multidimensional gas.' This new concept separates gas costs for calldata, computation, and state accesses, offering improved management of Ethereum’s resources amid the upgrade’s focus on reducing hardware requirements. By enabling node operation on smaller devices with these proposed changes, Buterin aims to make solo staking more viable and accessible.
