## AI overview

The article examines the use of FPGAs for low-latency computing and relates that hardware to the solving and verification of a large cryptographic puzzle. It describes how advances in computing architecture affected the puzzle's solution timeline and notes that FPGA-based computation solved it in two months.

## Source excerpt

At Jane Street, we have some experience using FPGAs for low-latency systems-FPGAs are programmable hardware where you get the speed of an application-specific integrated circuit (ASIC) but without being committed to a design that's burned into the chip. It wasn't so long ago that FPGAs were expensive and rare, but these days, you can rent a $5,000 card on the Amazon AWS cloud for less than $3 an hour.
