The 3-year dispute over the expansion of Bitcoin has seriously blocked the development process of bitcoin, and at the same time, it has been strongly besieged by innovative currencies such as Ethereum and Zcash, and has lost a huge amount of market share. The SBTC team gathered a large number of geeks in the community, determined to inject new momentum into the continued progress of Bitcoin. After gaining the approval and support of several respected community leaders, the SBTC team will fork at 498888 altitude to add new features to bitcoin. After a successful fork, addresses that previously held Bitcoins will receive the same amount of SBTC in a 1:1 ratio.
