the The number of empty blocks in the Bitcoin network is on the decline. Many of the Mining of empty blocks but it is still a thorn in the eye. Wrong: Empty blocks may have a negative impact on the Mempool, but on the other hand, for more decentralization in Bitcoin Mining. An Analysis.

the incentive structure of The Bitcoin mining as a balancing act in the field of tension between supply, demand, Bitcoin exchange rate, Hash Rate and Difficulty is complex. The relationship between costs and income of provision of computing power for the network is tight, the Mining, therefore, not always profitable. This was intended to be from Nakamoto also: Bitcoin Mining is not the security of the network for the purpose – the enrichment of the Miner.
against All odds, falling prices do not lead spiral to death, such as the Professor Atulya Sarin summons. Because the incentive structure of Bitcoin mining is just as complex as it is ingenious: With a declining rate drops logically, the real output from the Mining. Finally, the inflation rate in the network is fixed, a fall in prices may not be easy with more „effort“, that is to say a ramp-up of the ASIC, compensated for, by more miners mining more Bitcoin. All of ten minutes to come (currently) to 12.5 BTC into the network. The Miner can’t shake. The real revenue from the Mining declines in a bear market. The emphasis is on revenue – not Profit. Profit is simply the difference between sales revenue and costs. Sales drops by the just described context, miners are able to operate in the most profitable.
the Hash Rate and Difficulty Retargeting
And it goes like this: a decrease of sales, Miner the ability to remove individual devices from the network, you don’t have to close the whole Farm. In General, inefficient Miner will go first for the older generations from the network. This reduces the (current)costs and should pave typically the way to profitability.
One might argue that fewer ASICs on the network, that is to say the Hash Rate, a lower Chance of imply, to be able to blocks to successfully propagate. That is correct. Remedy the so-called difficulty retargeting algorithm creates. Finally, the network participants all 2.016 blocks (approximately every two weeks) to calculate the Difficulty Level.

Bitcoin Difficulty Target since August 2018. The sudden adjustment every two weeks is good to watch.
A low Hash Rate – let us remember: A number of miners have taken their devices from the network implies a lower Target Difficulty. That is, in the new cycle, the network should be even with the lower Hash Rate will be able to propagate every ten minutes a Block.
The thing with the empty blocks
But the Coinbase Reward (12.5 BTC) is not the only source of income for the Miner. Finally, they must collect all fees for transactions you include in the Block. So why Miner propagate still empty blocks?
we Look at which information in such a Block plug. The blocks are not empty, they contain data such as the Coinbase transaction to the Block Header and all other records that contain blocks anyway. To mine an empty Block, also requires Proof of Work. Although such blocks contain no transactions, they are not useless. You increase the accumulated energy that has flowed into the network, and make the Blockchain so that safer.
For the Mining of empty blocks Miner’s refrain, however, a part of their turnover. Why? Contrary to popular belief, the Find empty blocks requires almost as much „work“ as the Propagate edge full of blocks. A speed advantage is obtained.
The reason is much more profane: as soon As the Miner found a valid Block, you can immediately begin to perform the Proof of Work for the next Block in the chain. As you know already, and which transactions were included in the Block. Meanwhile, the competition needs to download the new Block, and verify a minimum of temporal disadvantage.

at the same time, all of the Miner with the proof of working for the new Block start. Up the verification process of the previous block is complete, is involved with only the Coinbase transaction. An empty Block is created exactly when Miner find a Block, before they could the previous Validate. Consequently, empty blocks occur very shortly after the previous Block.
Empty Blocks are not per se bad –
The Mining of empty blocks is not per se harmful to the network. You could also see it as a balance against the centralisation problem. As mentioned, those miners have a speed advantage, which could propagate the previous Block. Find empty blocks compensates for this advantage.
Nevertheless, it is of course desirable that the Miner transactions to include in blocks. An Excess of empty blocks could therefore be considered problematic, because the Mempool is growing.
The empirical evidence is clear: As Diar in its latest Newsletter, the number of empty blocks in the Bitcoin network since 2015.
number of empty Bitcoin blocks in the period 2012 to 2019.
in 2018, there were only 438 of the piece.
This Trend is likely to intensify with the forthcoming Reward Halving. So there is no reason to panic.
