Algo for FPGA. This will hurt gpu mining even more by moving gpu miners off that coin onto something else.
But it takes time to make bitstreams to FPGA or to create Asics, they are doing this to prevent 51% atacks, they will need the community to achieve this, not only big miners
Throughput comparison graphic in the article shows a xilinx FPGA running various algos including keccak256. It'll be a matter of month if not less before the network is controlled by FPGA. Given that its a large enough coin, bitstreams will be developed while its on the testnet. ASICs will follow within a year. This change does nothing for gpu miners. Just another fpga/asic mined shitcoin.
