Bitcoin SV(客户端实现)的 Open BSV license 协议由 MIT 协议衍生而得，该协议版权属于 Bitcoin Association。但这并没有限制大家在此基础上继续自行开发客户端，只需要更改遵守以下两点即可：
1，需要保留上述版权说明 2，只允许在区块高度 556767 上哈希值为 000000000000000001d956714215d96ffc00e0afda4cd0a96c96f8d802b1662b 的链(即 BSV)上使用
这份许可杜绝了 BTC/BCH 借鉴 BSV 的扩容方案，同时保持了今后继续分叉的可能性，如果再次出现分叉，只要该分叉决策符合现在(PoW 矿工投票累积工作量)的决策方式即可。
