According to Jihana Wu, co-founder of Bitmain, the reason for the empty blocks minning by Antpool's mining pool is errors in the operation of the equipment.

Shortly after the activation of the Segregated Witness protocol, the world's largest mining pool produced six blocks of less than 1 KB in size. It is worth noting that the empty blocks were also extracted by the famous Chinese pool BTCC. 

During the production of empty blocks,  there has been an increase in the number of unconfirmed transactions in the bitcoin network. So, on August 25, the number of unconfirmed transactions was about 90 000, and their size exceeded 100 MB. 

Currently, the number of unconfirmed transactions has declined and is less than 35,000, the size of the mempool is slightly less than 70 MB. This reported by the blockchain.info.

Bank of China Filed a Patent to Scale Blockchain Systems

Bank of China has filed a patent application for a process able to scale blockchain systems  
23 February 2018   95

According to a document released by China's State Intellectual Property Office (SIPO) on February 23, the application was invented by Zhao Shuxiang and first submitted on September 28 last year.

The application states that instead of letting a new block store transactions from its previous one, a data compressing system could be used to pack transactions from multiple blocks into what the patent calls a "data block."

For example, when the system receives a request to compress transactions from block 1 to 1,000, it causes a new data block to be formed and temporarily hosted on a different storage system. Then, the system will run the packed data through a hash function with a hash value. After that, the compression system will attach labels in order to identify blocks on the blockchain.

With the use of the described method, the patent claims a reduction in the amount of the data stored in new blocks as transactions mount in a blockchain while ensuring that data from all previous transactions will still be tamper-proof and traceable.

At the moment, the patent in the review process.
