In the past three months, the usage metrics of Ethereum has revealed a rather surprising trend; a sharp increase in the number of empty blocks mined.
According to Alex Svanevik, the Chief data scientist at CoinFi, this points at ‘spy mining’ as the overall woodcut utilization, the number of blocks processed a day and the stereotype time between each woodcut are all stable.
The technique stuff used by the illegitimate miner pools is tabbed ‘spy mining’, which involves miners stuff rewarded for mining without unquestionably processing any transactions on the block. In such instances, an ’empty block’ is formed.
Along with this, selfish mining is moreover gaining popularity within pools and involves miners trying to find the successor of a new woodcut without dissemination its existence to the network, giving them a throne start.
After a detailed search, two miner pools were found to indulge in this practice; F2Pool, currently the world’s second-largest mining pool, and Etherdig.

A Twitterati and crypto enthusiast, Ansel Lindner made some crucial observations. He said that this was corellated to the miners “realizing that the value of ETH doesn’t come from transactions, but marketing”. Linder tweeted:
“The success of Ethereum’s marketing is only partly correlated with the number of transactions. There needs to be unbearable volume to support the narrative, but not too much to make it extremely nonflexible to stay synced.”
He remoter observed that the recent visualization made by Ethereum developers to reduce woodcut reward to 2 ETH has miners chasing volume, surpassing the upcoming Constantinople nonflexible fork. This nonflexible fork visualization was made to write issues in the blockchain and cryptocurrency space, with a focus on remoter upgradesl.

In an struggle to maximize their profits, F2Poll and Etherdig started mining blocks without validating any transactions. This poses an unheard threat to Ethereum. The data shows a 15% faster rate of propagation for empty blocks, meaning that the spy miners were moreover getting a 15% increase in their total revenue.
If many miners resort to this, transaction times could increase and moreover rationalization a sharp increase in gas fees. Furthermore, if this continues, increasingly sincere miners would undeniability it quits and focus on other tokens, well-expressed Ethereum’s security.
Etherdig cashed in on the practice and mined over 1,250 empty blocks, starting mid-July this year, equal to a research by CoinFi, and Alethio, an analytics platform. The mining pool has placid an unscientific 3,750 ETH, worth over $862,500 as fees for mining these ’empty blocks’. This is viperous as Ethereum blockchain processes 5,800 blocks every day, over 540,000 total transactions.
This practice stems from the computational race that miners involve on a daily basis. In an platonic scenario, mining can only uncork without a woodcut is broadcasted.
The prerequisite to understanding this full-length is to understand that each woodcut in a blockchain contains variegated amounts of data. Whatever their limit is, it is not necessary for them to hold exactly that much data to be verified and widow to a chain.
The verifications happen when a miner codes all of the block’s data, tabbed hash, closes the woodcut and broadcasts it. This lawmaking is essential for the next block. However, some pools start mining on blocks privately, surpassing the broadcast. Though it is not possible to create a hash without first reading the block’s data, a new woodcut can be created from an once existing hash surpassing a transaction occurs.
As there is no transaction in this new block, it can not be nullified as there is no irregularity in transaction data. Miners get their hands on hashes through pools.
To get a head-start, some miners find a new woodcut and try to find its successor without dissemination to the pool.
Etherdig did exactly this and deployed a system which spied on pools, which are privately mining. This provided them with unbearable information to create their own empty block. This practice is detrimental as a mining pool which controls maximum computing power in the network can monopolize mining of that network.
Each of the empty woodcut mined by Etherdig contained no transaction data, but had the phrase “Interim Global Authority”.
In its early days, Bitcoin had moreover undergone a similar scenario.
However, this was quickly rectified as the token was in its early stages and one line of lawmaking was unbearable to prevent the malice from spreading. An upgrade was made on the network’s cadre code, making it difficult for miners to pry on other pools.
As Ethereum’s developer wiring is large [almost 250,000], it is a magnanimous task. It could either go the downward screw due to its developer volume, or it could rectify the system by taking wholesomeness of the large community.
