Permissioned blockchain systems provide a mutual-trust platform for data sharing and collaboration among organizations. However, performance bottlenecks limit their adoption in industrial applications requiring high transaction throughput and low latency. Recent advancements have focused on leveraging parallelism to improve performance, but transaction contention remains a significant challenge. The Optimistic Concurrency Control (OCC) mechanism, once widely used to manage transaction contention in permissioned blockchains, is valued for its simplicity and minimal design constraints. However, its reliance on the strategy of aborting conflicting transactions results in resource wastage and suboptimal performance, rendering it less favorable in recent research. This paper presents the Overpass Ledger (OPL), a high-performance permissioned blockchain system that utilizes an overpass-inspired workflow. To address transaction contention in such a highly parallelized workflow, the OCC mechanism is revisited and Re-Execution (ReX) is proposed, an enhanced OCC variant that efficiently re-executes conflicting transactions to eliminate transaction abortion and maximize resource utilization. By integrating ReX, OPL fully harnesses the advantages of parallel stage processing and concurrent transaction execution. Experimental results demonstrate that OPL achieves throughput improvements of$77\times$,$19\times$, and$4\times$compared to Hyperledger Fabric, BIDL, and FISCO BCOS, respectively, while maintaining consistently low latency.
