Exploring historical and contemporary blockchain network latency,
throughput,
scalability, reliability, and decentralization to assess technological readiness for decentralized
foreign
exchange markets.
Evaluation Framework
This framework evaluates blockchain networks across five dimensions to assess their suitability for
supporting the approximately $9.6 trillion in daily foreign exchange transactions. Although these
dimensions
are often optimized at the expense of one another, the severity of these trade-offs appears to decrease
over
time in response to continued technological innovation.

Key Metrics
Latency (L)

Congestion behavior under load
Reliability (R)
Probability of maintaining liveness and safety under adversarial conditions
Uptime; resistance to outages

Note: Unichain uses 200ms Flashblocks (10x faster than most L2s). 348M+ transactions
processed. 65% of sequencer revenue allocated to validators.
*Arc: ~3,000 TPS achieved with 20 geographically distributed validators; exceeds 10,000
TPS with 4 validators. Finality <350ms is deterministic.
†Tempo TPS: The ~20,000 TPS figure represents payment lane capacity as
specified in TIP-1010, not observed real-time throughput. Applies to TIP-20 stablecoin transfers using
500M block gas at 500ms block times.
