IOTA Crypto Currency (and an FPGA for the RPi)
Part 2: PiDiver — FPGA board for fast calculations
In the last issue we presented the ‘IOTA’ crypto currency which permits IoT nodes to pay other subscribers — for example for storing data . In order to perform IOTA transactions, a proof-of-work calculation task must first be solved; this protects the transaction database ("tangle") from spam. Even x86 computers sweat during the arithmetic task, but IOTA provides for smaller IoT nodes to outsource this work to specialized devices. The second part of the series introduces such a platform based on an FPGA add-on board for the Raspberry Pi.
