Activation is achieved when 750 of 1,000 consecutive blocks in the best chain have a version number with bits 1,2,3 and 14 set (0x20000007 in hex). The activation time will be the timestamp of the 750'th block plus a two week (1,209,600 second) grace period to give any remaining miners or services time to upgrade to support larger blocks. If a supermajority is achieved more than two weeks before 2016-01-11 00:00:00 UTC, the activation time will be 2016-01-11 00:00:00 UTC.
也就是说支持XT的区块标识是一个版本号( version number ),这个版本号的第1,2,3和14位数据位为1。所以对应的版本号二进制代码应该是0010,0000,0000,0111,但是这个数换算成16进制明明是0x2007,而不是原文中的0x20000007。我就晕了,这是网站上的信息有误还是我理解的不对?
XT的区块版本号究竟是8199(0x2007)还是536870919(0x20000007)?这个版本号到底在哪可以查看?
