a16z says blockchain throughput is no longer the biggest hurdle for financial markets, with predictable execution, ordering, resilience and privacy now taking priority

The a16z piece argues that aggregate blockchain throughput has grown more than 100x in five years, with some production systems processing tens of thousands of transactions per second, shifting the bottleneck to other requirements. It identifies predictability of inclusion and ordering, resilience against single gatekeepers, and pre-execution privacy as the key remaining challenges. The firm's researchers propose "Strong Chain Quality," reserving block space for transactions entering via multiple network routes, and note encryption techniques like timelock and threshold encryption to prevent front-running before finality.
