Solana’s engineering team released new consensus research that challenges the traditional “leader handoff” design and explores an architecture that does not require each block to reference its immediate parent. In a 10-node test cluster spanning Asia, Europe, and North America, the team demonstrated 10ms slot times with block leaders rotating every 10ms despite cross-region delays exceeding 100ms. The work is positioned as research only and does not change the project’s direction for Constellation, but it shows a potential path to moving beyond the network-delay Δ constraint.
