As the Ethereum community prepares for the impending Fusaka upgrade, attention has already shifted to the next major upgrade: Glamsterdam. This upgrade promises profound changes with two proposals currently attracting developer attention: EIP-7732 and EIP-7928.
The main proposal in this update is EIP-7732. This proposal, whose full name is Enshrined Proposer-Builder Separation (ePBS), seeks to fundamentally change the block creation process.
Instead of the block proposer (the validator chosen to create the next block) being responsible for constructing the entire block and its transactions, EIP-7732 proposes a separation of roles. Under this model, the proposer focuses on consensus validation, while a new figure, the block builder, is responsible for execution validation and assembling transactions.
EIP-7732 is a direct response to the growing concern about online transaction censorship. The direct benefit to users is increased censorship resistance and a more decentralized network. By making it difficult for malicious entities to exclude certain transactions, EIP-7732 would strengthen the fundamental principle of network neutrality.
Meanwhile, EIP-7928, or Block - Level Access Lists, is the second major project in Glamsterdam. This proposal seeks to optimize the way nodes process and validate transactions.
Currently, Ethereum nodes validate transactions in a block sequentially, one by one. This limits the speed at which blocks can be processed. The main goal of EIP-7928 is to allow parallel execution of transactions, which would significantly improve the speed and efficiency of the network.
For users, this translates into faster and potentially cheaper transactions. By optimizing how nodes access data, latency is reduced, which in turn can lower gas prices, a very tangible benefit for the community.
Fusaka: The next step before Glamsterdam
While Glamsterdam's proposals are exciting, the reality is that the Ethereum developer community's immediate focus is on the Fusaka upgrade.
This hard fork is expected to be implemented by the end of 2025 and will lay the necessary groundwork for future improvements. Fusaka is an infrastructure-focused update that precedes the more visible changes brought by Glamsterdam.
The main challenge developers must overcome is coordination and exhaustive testing. Setting a precise date for a hard fork is a complex process that requires the perfect synchronization of thousands of nodes around the world. The team must conduct a series of tests on testnets to ensure that all proposed EIPs work without errors and that there are no unexpected side effects that could compromise the network's security.
Any failure or delay in these tests could postpone the release date. Developers are required to work hard to ensure a smooth and safe transition, a necessary step before embarking on the more ambitious changes that Glamsterdam would bring.
