FlexChain: An Elastic Disaggregated Blockchain

Summary: FlexChain physically disaggregates CPU, DRAM, and storage in a permissioned blockchain to enable independent compute/memory scaling, reduce resource fragmentation, and support diverse smart-contract workloads. Adds a tiered elastic K-V store and parallelized validation to cut execution cost, achieving near‑SOTA throughput with ≤12.8% disaggregation overhead and lower CPU/memory use for compute- or memory‑heavy workloads.
