Bitcoin Cash mining difficulty

Brand new cryptocurrency mining difficulty: a close up of the latest information and predictions

Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen

Bitcoin Cash (BCH, BCC) is a hard-forked version of the original Bitcoin, which is different from the original cryptocurrency in terms of its blocksize limits (Bitcoin has a 1MB blocksize limit whereas BCC proposes 8MB blocks) and the difficulty adjustments (as reported, Bitcoin Cash will adjust the difficulty every 6 blocks as opposed to 2016 blocks as with Bitcoin).

The community’s attitude to BCC remains a bit diverse as the new cryptocurrency has a lot of things to work on. 

One of the problems with Bitcoin Cash is that hash power on the Bitcoin Cash chain started out low and has remained such, resulting in the extremely slow confirmation times taking hours.

It is believed, that this should improve over time, especially as Bitcoin Cash implemented a new difficulty algorithm designed to faster adjust back to normal. However, even with this algorithm, it could take weeks before blocks are found at typical ten-minute block intervals.

Jimmy Song, Bitcoin developer and entrepreneur, explains how the difficulty on the Bitcoin Cash chain will change over the next 10+ blocks in his blog.

Thus, according to the blogpost, Bitcoin Cash has a very particular rule about when difficulty can adjust downward. Rules for this are as follows:

  • Median Time Past of the current block and the Median Time Past of 6 blocks before has to be greater than 12 hours.
  • If so, it gets 20% easier to create proof of work. In other words, miners can find blocks 20% easier.

*Median Time Past (MTP) is just the median of the last 11 blocks. That is, put the last 11 blocks in time order and pick the middle one. This is used because sometimes blocks mined later have earlier time stamps (some technical reasons related to different clocks).

Jimmy Song also attaches a chart in order to help to project the difficulty adjustment:

As Jimmy Song claims, there are a bunch of blocks that have not been mined yet, but even if they were instantly mined, we would have 6 difficulty adjustments on blocks 478577 to 478582. This will reduce difficulty 20% each so we will have blocks that are 0.8⁶ ~ 0.262 as hard to mine. That is, miners will need to put in about 1/4 the work to mine a block.

This may explain why there was a 13 hour gap between blocks 478570 and 478571. Miners may simply have wanted the chain to be easier to mine!

Bitcoin Cash has changed its mining difficulty. 

As predicted, a Bitcoin fork has now changed its difficulty, currently operating at 26% of the main chain’s mining difficulty. The change happened at block 478577, which was found at around 4AM London time on August 3rd, 2017. It lowered difficulty to 80%, with the next 5 blocks lowering it further until block 478582 lowered it to 26%.

San Francisco Gathers Crypto Community in One Place

CB is a series of premium Blockchain events that connect ICO companies with the brightest industry minds and the latest in technological innovation. CB is the place where the future of Blockchain Industry is unboxed and brought to life. And when you consider this study by U.K. research firm Juniper Research, more than half of the world’s large corporations are looking into blockchain (distributed ledger technology), then it’s a high time you consider the blockchain technology. The research highlights that 57 percent of large corporations- defined as any company with more than 20,000 employees- were either actively considering or in the process of deploying blockchain. And two-thirds of companies surveyed said that they expected the technology to be integrated into their systems by the end of 2018.

It is clear that companies across the board have a significantly greater understanding of blockchain technology than was the case 12 months ago. This stems in part from a surge in R&D (research and development) both internally and in partnership with third parties, with a recognition that blockchain has the potential to be deployed in a variety of use cases.
As the number of research projects has increased, so too has awareness, both amongst the participants and elsewhere in their industries, with competitor companies in turn beginning to consider whether they too should seek to gain competitive advantage from deployment.
