If China’s interfering with hash rate and mining pools, then Bitcoin just proved its resilience


The Week in review

with Jason Deane

Things that hadn’t happened this time last week:

Plans for a Bitcoin City to be built on the back of a volcano based Bitcoin bond in El Salvador

  Estonia’s LHV bank becomes the first in that country to allow Bitcoin purchases

  Latin American E-Commerce Giant Mercado Libre puts Bitcoin on its balance sheet and announces it will begin accepting cryptocurrency

This, of course, is just a small selection of events that demonstrate just how quickly Bitcoin’s adoption rates are accelerating and just one of those subjects is enough to more than fill this morning’s weekly summary.

However, as I shuffled into my office early this morning with the first coffee of the day, I was confronted by two charts that rather took me by surprise and immediately presented me with the direction of today’s commentary – a breaking news item. Even though my Friday morning pieces are usually a leisurely stroll through the week’s events, it seems pertinent to break protocol and write about it.

The two charts were the Bitcoin price and the Bitcoin hashrate charts which were both showing a dramatic real time drop. In fact, at the time of writing, Bitcoin had dropped six per cent in around an hour, while the hashrate had dropped around 16 per cent (from recent average) in the hours immediately preceding. What was happening?

Some quick research and messaging my colleagues in the Bitcoin mining world revealed that this may be linked to further mining related shut downs by the Chinese government. It seems the major pools of viaBTC, Poolin, F2Pool, and BTCcom suddenly experienced connection interruptions. The only thing they all had in common was their DNS was provided by Alibaba Cloud, a Chinese owned operation. All had stopped resolving.

In other words, even though all the miners were almost certainly working as usual, their hash power wasn’t getting through, resulting in an artificially low global hashrate. The markets appear to have immediately overreacted and there may be choppy waters ahead, at least for a while.

Of course, the irony is that this small technical issue, resolved by simply moving to a non-Chinese DNS service, actually demonstrates just how resilient the Bitcoin network is and not how fragile it is. Take out the biggest mining pools and the network still works exactly as intended? That’s impressive.

Try doing that with any other monetary network and we’re straight back to “Sorry mate, cash only, card machine’s down”.

Just sayin’.

Have a great weekend!
