Abstract
One of the most important goal of a blockchain is its decentralized aspect. The growing popularity of ASICs for solving common proof-of-work algorithms has led to the opposite effect: blockchain mining industries are now centralized in countries where energy is cheap. New cryptocurrencies based on memory-hard proof-of-works have been introduced to counteract the use of ASICs and favor commodity hardware. This work explores the implementation of such algorithms on FPGAs, in a context of reclaiming the overflow energy of solar panels. One of them, Equihash, is deeply studied and described. A comparison with an optimized CPU version is provided, as well as a feasibility analysis. The objective is to determine how well an FPGA performs in this context.
