>To the extent that the Nasdaq market exists anywhere, it's within a single rack-mounted Dell server in a rented data center somewhere across the Hudson River. That machine routinely processes 70,000 orders, cancelations and trades per second but can handle up to 250,000 per second--enough to deal with trades on the Nasdaq plus the London and Paris stock exchanges with room to spare. The goal isn't VISA-level scale but Nasdaq-level scale btw. Solana had the right idea all along.
