Ethereum’s EIP-8198 aims to make block times configurable before cutting slots
Ethlabs is pushing Ethereum Improvement Proposal 8198, known as Quick Slots, as a candidate for the Hegotá upgrade, arguing that Ethereum can move faster without giving up censorship resistance, decentralization, or credible neutrality. The proposal does not call for an immediate aggressive cut in block times. Instead, it starts with a structural change: removing the assumption across specs and clients that Ethereum blocks always arrive every 12 seconds. Once that work is in place, slot times could be shortened gradually, with 10 seconds presented as the initial step and every later reduction requiring separate testing and consensus. The case for the change, as laid out in interviews with roughly 20 DeFi founders, application builders, and infrastructure researchers, spans market structure, user experience, censorship resistance, and L2 coordination. Supporters say fresher state updates would tighten quoting windows, reduce stale pricing, improve execution conditions, and help products ranging from DEX aggregators and options venues to tokenized stocks and ETFs. Others argue that faster slots would shorten the wait for censored transactions to find another inclusion path and make Ethereum’s base layer a more responsive settlement clock for rollups. At the same time, the proposal’s backers say the tradeoff only works if decentralization is preserved. That is why current work is focused on specifications, client implementations, downstream dependency checks, and compatibility with future consensus changes rather than on rushing a hard cut in slot time.
