The problem with this technology is that it’s slow. Like, really slow, especially in comparison to banks that deal with credit card transactions. Visa processes 150 million transactions per day, averaging out to roughly 1,700 transactions per second. And their capability far surpasses that, at 24,000 transactions per second.
The latest debates around Bitcoin’s technology have been concerned with this central problem of scaling and increasing the speed of the transaction verification process. There are two major solutions to this problem, either to make the amount of data that need to be verified in each block smaller, making transactions faster and cheaper or to make the blocks of data bigger, so that more information can be processed at one time.
Bitcoin Cash is a different story. Bitcoin Cash was started by Bitcoin miners and developers equally concerned with the future of the cryptocurrency, and its ability to scale effectively. These individuals had their reservations about the adoption of a segregated witness technology, though. They felt as though SegWit2x did not address the fundamental problem of scalability in a meaningful way, nor did it follow the roadmap initially outlined by Satoshi Nakamoto, the anonymous party that first proposed the blockchain technology behind cryptocurrency.
