Throughput is not a panacea; financial-grade blockchain requires "determinism." In March 2026, a16z argued that the root cause of DeFi's inability to support truly large-scale financial markets lies in the lack of "predictability of transaction inclusion." Under a single-leader mechanism, the concentration of transaction ordering power leads to covert censorship, arbitrage exploitation, and price degradation. The article proposes that for blockchain to serve as financial infrastructure, it must achieve short-term censorship resistance (ensuring transactions are promptly included on-chain) and invisibility (privacy before confirmation). By eliminating the leader's informational advantage, it can provide market makers and high-frequency traders with a fair, low-latency execution environment.
