Cryptocurrencies like Bitcoin are predicated on blockchain technology, which stores information about crypto transactions within “blocks” of data that can contain 1 megabyte of data. As the currency grew more popular, these data blocks filled up, slowing down bitcoin transactions and increasing transaction fees. Some Bitcoin developers proposed a solution that would effectively reduce the amount of data needed in each block, but others believed this would compromise the integrity of the cryptocurrency, so they created their own version of Bitcoin in August 2017 and called it Bitcoin Cash. Bitcoin Cash has blocks that can store 8 MB of data, allowing for faster and more frequent transactions with lower fees. Bitcoin Cash may be newer and less popular than its predecessor, but its scalability means it has incredible potential for growth.
