举个例子吧.
你赚了 0.1+0.2+0.3, 你要发 0.51 出去. 你的提交是 input: 0.1+0.2+0.3, output: 0.51+0.09. 其中 0.09 进入你自己的另一个账户. 0.51 发给了目标.

ipv6 用的人实在还太少... 如果 domain.com 是 google 的话, 你需要用参与 google ipv6 计划的 ISP 提供的 DNS 才能得到 ipv6 解析结果(ipv6 开头的除外). ::ffff:IPv4 是给双栈用的 ipv6 地址, 也就是说这是个废物. NAT64 又不是对所有人都开放.

那是因为没取到 deepbit 的数据. 仅此而已

这个图几乎没有过准确的时候. 在其他各家大矿池没有问题的时候, other 一般应该 < 5%, 从来都是这个比例. 由僵尸网络引起的那次除外.

@napoleonu v2ex 太小. 用 weiphone 这个级别的比较有说服力... v2ex? 0.3-0.5 即可.

数据库双机热备不足以支撑大应用啊, 不看好. 数据库太差了, 和 GAE 距离太大, 没法追...

@jiangchun9981 注意手续费.

实测 14h, 比理论收入高 23.9%, 未计 deepbit PPS, 未计 bitcoins.lc 上未确认的 shares (预计 0.03+)

刚才 deepbit 最低只有 ~630G

java.lang.Exception: getWork error
long poll: Long polling is restarting, this doesn't effect mining
long poll: Deepbit is temporarily unavailable

---这是偶碰见的 deepbit 出错信息

忘了说那个 queue 的功能了. 那个在另一篇里有说明, 防止 miner is idle, 保证长期满速工作.

那只是提升之一. 独家的 pool 推荐算法, 客户端支持 hopping 缺一不可. 重复提交(从其他分支移植来)减少网络损失, failback 功能(已进入官方版本, 但 hopping 与其有冲突, 做了大量的修改以保留该功能) 让人安心不怕 DDOS...

虽然话说如此, 服务端暂时稳定性还不够, 被 deepbit 和 btcguild 搞的挺难受的...

cont.
每有 long polling 送来新 block 的时候, 就会自动查询新的 best pool. 此外每 300s 查询一次, 以减少 shares 浪费.

目前情况: 服务端算法不良导致错过了 deepbit 的一小波高潮. 已修正.

验证: 21:53, 21:55, 22:07 三块是 deepbit 的. 22:01 的属于 bitcoins.lc

可以的. 条件是必须直连 DNS.
