如果你要硬分叉bitcoin需要多少钱?How much does it cost to hardfork bitcoin?
昨天有朋友问我,上次不是才刚硬分叉bitcoin cash出来,怎么又有bitcoin gold要硬分叉出来啦?是不是任何人都可以随便硬分叉bitcoin呢?
我想了一下,其实并不是任何人都可以随便硬分叉bitcoin,因为如果你没有算力,你分叉出来的新coin是没有价值的,我个人觉得,如果你要硬分叉bitcoin,你最少要有5%的bitcoin算力才有机会,不然的话,别人随随便便来一个51%的攻击,你分叉出来的新coin立刻完蛋
好了,让我们来算算看5%的算力需要多少钱
现在bitcoin的总算力是 10,351,762,428 GH/s
你需要5%是 517,588,721 GH/s
再看看矿机是多少钱
就说我们买Antminer S9 好了,$3000美金有14 TH/s
那 517,588,721 GH/s 除 14 TH/s
你需要 36970 个Antminer S9
也就是 $100,911,714
差不多1亿美金的矿机你才能有5%的算力
所以呢,如果你有1亿美金买矿机,再加1亿美金在市场上顶住价格别让你的新coin暴跌你才能去硬分叉bitcoin
谢谢阅读
Hello Steemit friend, yesterday my friend ask me why are there so many hardfork incoming? can anyone just hardfork bitcoin?
My answer to this question is no, because if you dont have the mining power to hardfork bitcoin, your new coin will have 0 value, because anyone can 51% attack your coin and your coin will be dead, so to hardfork bitcoin you need at least 5% of the mining power of bitcoin
but how much does it cost to have 5% of the mining power?
Let us do the calculation, as you can see, bitcoin mining power is now stand at 10,351,762,428 GH/s
5% is 517,588,721 GH/s
let say you bought Antminer S9 to mine it, which cost $3000 each and have a mining power of 14 TH/s
so you would need 517,588,721 GH/s divide by 14 TH/s
= 36970 Antminer S9
36970 Antminer S9 would cost you about $100,911,714
So as you can see, you would need at least $100 million to buy the machine for 5% of the mining power and you might need another $100 million to hold the price of your coin if everybody just start dumping your coin, so it is not anyone who can hardfork bitcoin but only a selected few can do it
