Bitcoin Gold

Bitcoin Gold is a distributed digital currency. It is a hard fork of Bitcoin, the open source cryptocurrency. The stated purpose of the hard fork is to restore the mining functionality with common Graphics Processing Units (GPU), in place of mining with specialized ASIC (customized chipsets), used to mine Bitcoin. ASIC resistant GPU powered mining provides a solution, as this kind of hardware is ubiquitous, and anyone can start mining with a standard, off-the-shelf laptop computer. Bitcoin Gold was hit by double-spending attack on May 18, 2018. Bitcoin Gold hard forked from the Bitcoin blockchain on October 24, 2017, at block height 491407.

Apple Pay

The banks were willing to work with Apple in the face of efforts like Bitcoin and the Merchant Customer Exchange, which seeks to work around the card networks. Early reviews of the service regarded it as easy to use, but were not sure whether the service would become widely adopted. The Verge Nilay Patel wrote that the product demo was "remarkably smooth" and "a cohesive user experience". Patel said the process took five to ten seconds at a retail card reader, and added that it may be less smooth at stores such as Walgreens, where cashiers prompt customers for loyalty cards and charity donations. The New York Times Neil Irwin wrote that Apple exaggerated the inconvenience of credit cards.
