内斗继续！比特币现金开始挖矿，比特币价格骤跌逾6%

原本已经尘埃落定的比特币分叉方案又起波澜。

The already defunct Bitcoin forklifting programme has been further magnified.

7月21日，比特币分叉方案BIP91已经获得全网算力支持，一致同意先进行隔离见证升级，并在之后的6个月内把底层区块链的区块大小升级至2M。然而“搅局者”出现了——挖矿巨头比特币大陆旗下的矿池ViaBTC准备了一套硬分叉的体系，基于比特币的原链推出“比特币现金”（Bitcoin Cash，下面简称BCC）。

On 21 July, the Bitcoin forklift BIP91 was supported by a full web-based calculation that agreed to first upgrade the isolation witness and upgrade the block size of the bottom block chain to 2M within the next six months. However, the “martgers” have emerged — ViaBTC, a mine pond under the Bitcoin flag of the mining giant, has prepared a hard-fork system for the introduction of Bitcoin cash based on Bitcoin's original chain (Bitcoin Cash, hereinafter BCC).

8月1日20时20分，比特币现金开始挖矿，比特币价格随之骤跌逾6%。这是比特币的新的分支还是另外一种“山寨币”，业内论调不一，但是此前BCC提前报价已经达到2000元，也就是已经超过比特币价格的十分之一。

At 2020 hours on 1 August, Bitcoin began mining in cash, with a sharp drop of more than 6% in Bitcoin prices. This is a new branch of Bitcoin or another form of “shelter currency” with variations in industry, but before the BCC’s advance offer had reached $2,000, one tenth of the price of Bitcoin.

“这报价是在炒空气，”一位比特币从业者对澎湃新闻表示。

“This offer is for fumigating air,” a bitcoin practitioner said on the news.

BCC的扩容方案BitcoinABC的官网显示，这是一种比特币硬分叉方案，相较于之前7月23日达成的扩容共识而言更加简单明确，并且将会把每个区块的容量从1MB提高到8MB。

BCC's outreach programme Bitcoin ABC's network shows that it is a bitcoin hard fork, which is simpler and clearer than the previous consensus on expansion on 23 July, and will increase the capacity of each block from 1MB to 8MB.

一位比特币交易所人士对澎湃新闻表示，目前中国的交易所态度比较一致，就是如果比特币大陆方面一定要做成BCC，那么所有交易所会将之视作“山寨币”的一种，而不是比特币的分支，但是由于本身也是基于比特币的区块链形成的链，所以交易所会给用户1:1赠送BCC。

One Bitcoin exchanger said to the news that the current Chinese exchange was more consistent in that if the Bitcoin mainland side had to be BCC, all exchanges would see it as a “sample coin” rather than a branch of Bitcoin, but because it was also a chain based on Bitcoin's block chain, the exchange would give BCC to users 1:1.

“BCC是个竞争币，除了BCC的前身与比特币同根，但是分叉了以后，就无关了——好比人们利用了比特币的源代码，改了一下出来的新币，”上述比特币从业者表示。

“BCC is a competitive currency, apart from BCC's predecessor and Bitcoin, but when it splits, it doesn't matter — as if people had used the bitcoin source code to change the new currency,” says the above-mentioned Bitcoin practitioners.

上述人士表示，目前BCC得到了一些矿工的支持，他们愿意用自己手中的部分算力去试验新的币种，但是即便不支持，比特币大陆也可以“单干”，因为比特币大陆在挖矿业拥有40%以上的矿池。

According to the above-mentioned sources, the BCC is currently supported by miners who are willing to test new currencies with some of their own numeracy, but even if they do not, the Bitcoin continent can be “single” because the Bitcoin continent has over 40 per cent of the ponds in mining.

他还表示，比特币大陆之外不一定有很多矿工会支持BCC，也无法判断挖BCC是不是比挖BTC（比特币）更赚钱，这需要分情况来看——如果挖矿难度一样，那么显然是价格更高的比特币更加赚钱，但如果BCC系统降低挖矿难度，也有可能获得超额收益。

He added that it was not necessary for a large number of mining unions outside Bitcoin to support BCC and that it was not possible to determine whether digging BCC would be more profitable than digging BTC (bitcoin), which would require a case in point — if mining was as difficult as mining, it would obviously be more expensive than bitcoin, but if the BCC system made mining less difficult, it would also be more likely to yield excess gains.

目前，中国交易量排在前三的比特币交易所——OKCoin币行、火币网、比特币中国都表示将会支持BCC交易，用户在三大平台的比特币也会按照1：1的比例赠送BCC。

At present, China's trading volume is ranked among the top three Bitcoin exchanges — OKCoin, the Currency Network, and Bitcoin China — all of which have indicated that they will support BCC transactions, and the users of the three platforms, Bitcoin, will give BCC at the ratio of 1:1.
