At 0:40 a.m. Beijing time on november16,2018, BCH conducted a high-profile hard bifurcation, marking the first computing power battle in the history of digital currency. The two sides of this power duel are, on the one hand, Craig Wright, who claims to be "Nakamoto cong", and the nchain development team supported by Calvin Ayre, the gambling tycoon behind him, on the other hand, the bitcoin ABC development team, as well as the backers, bitcoin founder Wu Jihan and "bitcoin Jesus" Roger ver. As the two sides failed to reach an agreement on how to best develop BCH and deploy updated code, BCH finally moved towards hard bifurcation. BCH was divided into two camps, BCH ABC and BCH SV, and agreed to fight for life and death with computing power. BCH was derived from the hard bifurcation of bitcoin in August, 2017. After a year, BCH was split again. This time, BCH fought against each other through computing power competition without playback protection. As the fourth largest digital currency by market value, BCH computing power battle has attracted wide attention in the industry, and has spread to bitcoin and the entire digital currency market, bringing a far-reaching impact on the future community governance model. The BCH calculation battle began on the 16th and ended on November 23 when SV conceded defeat and gave up the title fight. It lasted more than a week. Since then, the battle of computing power has officially ended, BCH has branched into BCH original chain and BSV chain, and BSV was born. "SV" in BSV (bitcoin Satoshi vision) is the abbreviation of Satoshi vision. It aims to realize the original vision of large-scale capacity expansion on the chain and become a global point-to-point e-cash and value data transmission network.

The bchsv chain will use and follow the original specifications outlined by Satoshi Nakamoto in the bitcoin white paper, so it is
