Bitcoin mining difficulty decrease
LONDON, Jan 6 Reuters - The global computing power of the bitcoin network has dropped sharply as the shutdown this week of Kazakhstan's internet during a deadly uprising hit the country's fast-growing cryptocurrency mining industry. Kazakhstan became last year the world's second-largest centre for bitcoin mining after the United States, according to the Cambridge Centre for Alternative Finance , after major hub China clamped down on crypto mining activity. Russia sent paratroopers into Kazakhstan on Thursday to help put down the countrywide uprising after violence spread across the tightly controlled former Soviet state. Police said they had killed dozens of rioters in the main city Almaty, while state television said 13 members of the security forces had died. The internet was on Wednesday shut down across the country in what monitoring site Netblocks called "a nation-scale internet blackout". The move would have likely prevented Kazakhstan-based miners from accessing the bitcoin network.

Bitcoin Mining Difficulty Records Largest Drop in History, Price Jumps
The Bitcoin Difficulty Estimator whose role involves providing updates every second, showed that the Bitcoin network adjusted its mining difficulty at UTC on Nov. This phenomenon gives miners a reason to rejoice as their profitability is set to rise significantly.
The difficulty adjustments occur approximately every two weeks. Basically, Bitcoin mining difficulty shows how time-consuming and difficult it is to mine a new block for the Bitcoin blockchain.
The difficulty decreases or increases over time, depending on the number of miners in the network. However, there are other explanations pointing out factors affecting the mining difficulty.
For example, miners have professional experience in their work and therefore know how to respond to their mining activities. The current difficulty decline is due to the reduction of the average total computing power racing in the network in the past two weeks as several Chinese miners have unplugged their machines to migrate from hydropower plants to fossil fuel power stations. Jason Dane, a Bitcoin analyst at Quantum Economics advisory and investment analysis company for the cryptocurrency markets, said:.
The rest of the network simply takes up the slack and the difficulty adjusts accordingly. Dane said that people might think that a major decline in mining difficulty shows a lack of confidence or a low price in Bitcoin.
He, however, said that this is not the case based on the current negative adjustment seen yesterday. Based on the time of writing this article, the next adjustment is likely to take place on Nov.

Ethereum (ETH) mining difficulty up until January 9, 2021
This time, difficulty drops 15 percent, the second-highest in the history after the highest in November This year saw a continuous ascent in Bitcoin mining difficulty until two months back when it started dropping down as shown in the chart below. During these last two months, as prices took a hit, Bitcoin miners shut down their rigs that resulted in the fall of hash rate and subsequently the mining difficulty. Actually, every two weeks, the hashing difficulty algorithm of Bitcoin is adjusted in order to maintain the usual 10 minute block time. Since the prices took a hit in mid-November, it has been already adjusted twice. And as a result of this adjustment, the difficulty has been on a downward spiral.
Bitcoin mining difficulty rising again as miners resettle and get back to work
For Bitcoin enthusiasts, first, the good news. It is reported that mining difficulty for the world's largest, and most valuable, cryptocurrency just dropped by more than a fourth. Which means, it is now easier and more profitable to mine Bitcoins. However, if one scratched beneath the surface, it would become evident that the easing of in mining difficulty is a move that is linked ultimately to the high environmental cost that the activity was seen as extracting. Authorities in China, which accounted for as much as 65 percent of the global production of Bitcoins last year, have cracked down on mining after it became evident that miners were using up massive amounts of energy. What makes Bitcoin unique is that it is nothing like existing currencies in either the way it is built or how it functions. For starters, while it is called Bitcoin, it is neither a coin nor any kind of paper money but just lines of computer code.
Mining Difficulty
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since
Bitcoin: new record for the difficulty of mining
It has seen a host of major mining pools and organisations shut down their miners. However, as is the nature of Bitcoin and its decentralised network of miners, as the mining input decreases, so does the hashrate, and thus the difficulty of mining Bitcoin also decreases. The hashrate of Bitcoin has been in decline since October, but the continued exodus has seen the difficulty drop by 15 percent, the second-largest drop in history. Mining is always a fine balance of profitability, and while the price of the asset has made it unprofitable for most miners, it remains to be seen whether this drop in hash, and subsequent ease in difficulty, will be enough to entice miners back and push the hashrate up again. However, the drop in October was an overall effect of a bear market which has lasted nearly a full year. With this drop amounting to an 18 percent decrease in difficulty, it is substantial, considering the last time the difficulty decreased was on July 15, and such decreases have been a rare occurrence over the past several years.
Mining difficulty chart
Miners secure the Bitcoin network by competing against each other to solve computational problems in order to make blocks, which are comprised of BTC transactions. Accordingly, one of the key measurements in the Bitcoin ecosystem is the mining difficulty rate, which tracks how hard it is for miners to create new blocks and automatically recalibrates after every 2, blocks, an occurrence that happens roughly every two weeks. Mining difficulty is thus ever-changing and contingent on activity — simply put, the rate will go higher as more miners compete to mine bitcoin or lower if competition draws down. On March 9th, the Bitcoin mining difficulty rate clocked in at A little over two weeks later on March 26th, the difficulty acutely declined by some 16 percent, having sunk to around To be sure, nothing is inherently undue about this readjustment — the Bitcoin network is acting normally and as expected here. Indeed, the only time cryptoeconomy watchers have seen a bigger difficulty drop to date was all the way back in the fall of , when the rate fell by 18 percent.
While many experts have dismissed the recent rumors around a government crackdown on Bitcoin mining in China, it seems that miners operating in the country have already begun pulling out anticipating the worst. The most notable decrease was seen last week when the mining difficulty adjusted to Screengrab showing the Bitcoin network difficulty between Feb.
The mining difficulty of a cryptocurrency is how difficult it is to find the right hash for the next block. The mining difficulty of a cryptocurrency is an indication of how difficult as well as time-consuming it actually is to find the right hash for each of the blocks. Mining difficulty can be defined as a measurement unit that is used in the process of Bitcoin mining as an example. The difficulty indicates how difficult it is to solve the complex cryptographic puzzle in question. The difficulty of mining new blocks can either increase or decrease over time, and this is highly dependent on the number of miners within the network. The more miners there are, the more difficult the cryptocurrency is to mine.

Monthly figures are as of the end of that particular month.
Block time defines the time it takes to mine a block. Both in bitcoin blockchain and ethereum blockchain, there is an expected block time, and an average block time. In bitcoin, the expected block time is 10 minutes, while in ethereum it is between 10 to 19 seconds. Both bitcoin and ethereum, at the time of this writing use a proof of work based distributed consensus algorithm ethereum is planned to move to a proof of stake based algorithm with its serenity release.
