Ethereum researchers are developing a consensus redesign intended to reduce transaction finality from roughly 15 to 16 minutes to seconds. The model separates block production and fork choice from irreversible confirmation, allowing smaller committees of about 256 to 512 validators to handle rapid activity while the full validator set supports a parallel finality mechanism. Ethereum Foundation researchers have formally verified key safety and finalization properties of the model in Lean 4 without using "sorry" placeholders. Ben Edgington outlined a staged roadmap in a May 2026 blog post, with protocols including Minmitt and Goldfish being researched for later single-round finality improvements. The work forms part of Ethereum’s broader "strawmap" roadmap, which targets finality improvements likely arriving by 2029 and could reduce delays and reorganization risks affecting high-value transactions and cross-chain bridges.
