SWMT: A Sliding Window Merkle Tree with Delayed Writes for Scalable Blockchain State Management
Summary: SWMT tackles blockchain state-tree bottlenecks by decoupling commitment from execution via delayed writes: a cyclic in-memory sliding-window cache buffers recent updates before folding them into the Merkle/Verkle tree. TCP-like adaptive windowing keeps proof verifiability intact while cutting commitment latency up to 61x on Ethereum traces. (summarized by gpt-5-mini on Apr 11 2026)
