Abstract: In this piece we present data displaying the proportion of empty blocks blocks containing only the coinbase transaction produced by the different mining pools, over time.
We look at the mining methodologies pools could choose and how these policies could impact the proportion of empty blocks. Some claim that circumstantial evidence supporting this allegation, is that some mining pools produce more empty blocks or more smaller blocks than other mining pools.
Readers have asked us for data backing up this assertion, as only limited data has been published on this specific topic, as far as we are aware. We are not going to draw any firm conclusions from the data on the prevalence of empty blocks, however we present it for your consideration. Figure 1 — Summary chart — Rolling average percentage of empty blocks over 1, block period by pool.
Due to the different frequency with which different pools find blocks, the same dates on the chart could reflect different periods. Charts illustrating the proportion of empty blocks by mining pool. Figure 2 — Percentage of empty blocks by pool — YTD. Figure 3 — Percentage of empty blocks by pool — Figure 4 — Percentage of empty blocks by pool — Figure 5 — Percentage of empty blocks by pool — Figure 6 — All time percentage of empty blocks by pool — Monthly data.
Figure 7 — onwards — percentage of empty blocks by pool — Monthly data. Figure 8 — YTD — percentage of empty blocks by pool — Monthly data. Summary statistics by year top 11 pools ranked by the last 12 months. Figure 9 — Summary table for to 25th August. Figure 10 — Summary table for Figure 11 — Summary table for In order to build on top of the previous block and extend the chain, mining pools need the hash of the previous block, but not necessarily the full block with all the transaction data.
Mining pools are in a rush to make the chain as long as they can as fast as possible to increase profits. Therefore miners often have a policy of trying to find the next block before they have even had time to download and verify the previous block.
If this occurs, a miner typically avoids putting any transactions in the block apart from the coinbase transaction , as the miner may not know which transactions were in the previous block and including any transactions could result in a double spend, resulting in an invalid block rejected by the network.
The efficacy of SPV mining is debated in the Bitcoin community, with advocates claiming this is legitimate profit maximising activity. While opponents of this policy claim it reduces the transaction capacity of the network since empty blocks still keep the mining difficulty up and that it increases the probability of an invalid block receiving more confirmations, ensuring the network is less reliable for payments as double spends are more likely.
Different mining pools are said to have different policies. As figure 9 shows, Bitfury produced 0. SPV mining is believed to be the primary cause of this difference. For example figure 8 could be said to demonstrate the following:. In our view this hypothesis is certainly possible, but also reasonably weak. Further evidence may be required to draw any firm conclusions. Another factor to consider is timing. SPV mining occurs because miners are keen to get to work on the next block quickly, before they have had time to validate the previous block.
Therefore, in the majority of cases where miners do not quickly find the next block, say within 30 seconds, the impact of SPV mining should be limited, since miners do have time to validate. Figure 12 below is a repeat of figure 3 above, except this time we have excluded the empty blocks which occurred within 30 seconds of the previous block being found.
This may partially remove the impact of SPV mining. Although the data with respect to timing may not be reliable. Figure 12 — Percentage of empty blocks by pool — 30 second gap or more from the previous block. The analysis in this piece only looks at empty blocks. In a later piece we plan to look at the proportion of these smaller blocks in more detail.
In the below analysis we compared the timing between the previous blocks and the blocksize, for two particular pools. The charts illustrate that the variations between pools are not just about empty blocks, but also smaller blocks.
The time gap may not be reliable. It is difficult to draw any firm conclusions from these charts. However one ironic thing stands out to us, from this analysis. The pools arguing most vigorously for larger blocks, tend on average, to produce smaller blocks.

Available in monthly intervals starting from September , it extrapolates from a representative sample of geolocational mining facility data. This sample is based on the aggregation of individual pool distributions that are periodically collected from several Bitcoin mining pools through a dedicated API. We have partnered with several Bitcoin mining pools to collect geolocational mining facility data in a non-obtrusive and privacy-preserving manner. Each participating mining pool aggregates IP addresses on their end to create an average geographic distribution of total pool hashpower by country and region. Pools then periodically push their individual distribution to our database via a dedicated API endpoint , connecting with a unique, pseudonymous access token that obfuscates the identity of the pool.

With increased difficulty, the probability of mining a key block is lower. Therefore, the miners can form mining pools where they share the processing power over the network so they can mine key blocks more often. They split the reward according to the amount of work they contribute to mine a block. The mining pool is formed of a mining pool manager that manages the pool and gets a fee for that and the miners. Even though the node does not mine the key blocks, it still produces the key block candidates that do not have nonce and pow set. NOTE: The pool manager does not track the key block candidates created in the past.

Ever since the introduction of the first mining pool for Bitcoin in November , mining pools have been used by miners to reduce the variance in rewards of Proof-of-Work cryptocurrencies. Miners connect their computational resources to a pool - and the pool is responsible for dividing the work between the miners to prevent doing duplicate work.

A team affiliated with the University of Cambridge has released a new bitcoin data tool showing the countries with the highest concentration of mining activity. They are hoping to plug in data from more mining pools and entities to create a more comprehensive picture. Many miners use virtual private networks VPNs to mask IP addresses and can make locations harder to pin down. In the methodology page, CCAF said that they had noticed this was particularly prominent in Zhejiang province. Blandin said the map may at least confirm some Chinese miners may actually migrate from Sichuan to Xinjiang after the rainy season. The deal is an advance purchase agreement between Novavax and Israel's Ministry of Health. In its press release on the matter, Novavax wrote that it "will work with the Ministry of Health to obtain the necessary authorizations and finalize plans for distribution in Israel pending regulatory approval.
