Topic: 比特币社区议论纷纷：Ghash.io令人不安的高散列率 (Read 775 times)
制造一点利空
把老版本的个人挖矿的功能加到如今的新版本上，大家没事儿就开一开，呵呵
比特币的算力越来越高，高的恐怖.矿池就那几个.
应该建造更多的矿池来分散算力集中造成的51%危险
都没利空消息了，所以要制造一点
对潜在的51％攻击的担忧再次在比特币社区发酵，有消息称，在过去24个小时, 矿池Ghash.io已经达到了一个令人不安的高散列率（hashrate)。
社交共享网站Reddit.com的比特币版块，发布了超过10个相关主题的分享帖子。
矿池Ghash.io的散列率高达47％ – 非常接近51％的禁区，达到51％将打开攻击大门，51％攻击是通过多数表决来实现的。
51％攻击之一是双重消费。也就是说，同一个比特币使用两次。这样的攻击可能会对比特币社区造成灾难性后果，所以这并不令人惊讶，社区成员正在急忙敦促其他人远离Ghash.io，转移到其他矿池，。
“在过去的24小时，Ghash.io散列率高达47％。如果可以，请转到其它矿池，“ 红迪网（Reddit）上一个帖子呼吁。一个用户的跟帖被顶上去了，这个评论说转移矿池可不容易：
“需要明白，只是告诉人们转移是不够的。这是经济学，较大的矿工（这是唯一真正重要的因素）都不会转移，除非有经济诱因。至关重要的是，我们需要给这些矿工更好的理由，通过推动P2P或更好的竞争来实现去中心化。“
51％攻击的恐惧已经不是第一次笼罩在社区上空。
今年年初，社区遇到类似的情况，同我们在这个周末看到的一样歇斯底里。
该消息促使Ghash.io发出关于此事的声明：
“GHash.IO将采取一切必要的预防措施，以防止所有散列功率（hashing power,）达到51％，维持比特币网络的稳定性。”
他们补充说，“（他们）的计划是扩展比特币社区以及利用散列功率发展一个更大的比特币经济体。”
“如果比特币出什么事，作为一个整体，我们在物理硬件的投资遭受风险，热爱比特币的人遭受伤害，我们看不出占有51％的算力有什么好处。”
但Ghash.io尚未正式出台关于此次事件的声明。
评论：利益机制的设计，才是保护比特币的最好盔甲。
Bitcoin Community Abuzz Over Ghash.io’s Uncomfortably High Hashrate
Fears of a potential 51 percent attack are once again brewing in the bitcoin community with news that mining pool Ghash.io has reached an uncomfortably high hashrate in the past twenty-four hours.
The bitcoin subreddit on social sharing website Reddit.com, with over ten shares on the page related to the matter.
The pool’s hashrate reached as high as 47 percent — extremely close to the 51 percent envelope that would open the door to attacks that could be carried out by the majority.
One such attack would be double-spending transactions. That is, using the same amount of bitcoin twice. Such an occurrence could have devastating consequences in the community, so it’s no surprising that members are urging others to distance themselves from Ghash.io and move to another pool.
“Ghash.io at 47% hashrate for the last 24 hours. PLEASE move to another pool if you can,” exclaims one submission on Reddit. A fellow user’s comment was voted the top saying it really isn’t that easy:
“People need to understand that simply telling people to move pool isn’t enough. This is economics, the larger miners (and the only ones that actually matter) are not going to move unless there is economic incentive . It is vital we give these miners reason to decentralize via pushing P2P or better competition.”
This isn’t the first time fears of a 51 percent attack have loomed on the community.
Earlier this year, the community encountered a similar situation, equally met with as much hysteria as we’re seeing this weekend.
The news prompted Ghash.io to issue a statement on the matter at the time, in which the pool said:
“GHash.IO will take all necessary precautions to prevent reaching 51% of all hashing power, in order to maintain stability of the bitcoin network.”
They added that, “[their] plans are to expand the bitcoin community as well as utilise the hashing power to develop a greater bitcoin economic structure.”
“If something happened to Bitcoin as a whole it could risk our investments in physical hardware, damage to those who love Bitcoin and we see no benefit from having [a] 51% stake in mining.”
Ghash.io has not yet issued a statement on this occasion.
