2200 TPS is the headline number but Sean Bowe's own blog explicitly defers benchmarks to a future publication — the actual Tachyon breakthrough is solving nullifier state growth, not raw throughput. Oblivious sync is clever cryptography, but it shifts data availability onto wallets: lose your wallet state and there's no chain-level recovery, which is a brutal tradeoff for something pitched as "planetary scale money." Quantum resistance landing as a side effect of decoupling wallet protocol from on-chain shielded protocol is genuinely elegant, though Mina's struggles with recursive proof complexity in production should temper expectations on the PCD aggregation path.
