Hashrate Option

The underlying of the hashrate option is the block difficulty. Each block in Ethereum has a difficulty field and for any chain we can calculate the total difficulty of the chain by adding difficulties of all the blocks from genesis to the head block.

Block difficulty fluctuations are caused by a few main factors:

  • technological progress (hashrate growth resulting from faster GPUs and ASICs)

  • miners joining or leaving the Ethereum mining market

  • changes to the calculation methods of difficulty

When buying or selling a difficulty option you are taking a view on one or all of the above - you may expect some sudden difficulty change due to a new ASIC introduction (technological progress) or some network upgrade to happen, or miners exodus or influx cause by the economic of mining on Ethereum vs other protocols.

Note that hashrate can be mostly expressed in difficulty but it is an approximation (we need to exclude changes to the calculation methods).
