The two companies have agreed to test a system built on technology from the open-source Hyperledger blockchain consortium to determine whether they can use an immutable ledger to record orders, invoices and otherwise collect data about company operations, as coindesk.com details. 

According to the companies, the ultimate goal is to develop a record of every transaction that can be accessible by anyone in the company, thereby streamlining the process needed to order an item. Thus, for now, Hitachi's process involves ordering an item, confirming the order, creating an invoice and approving the invoice. Hitachi intends to incorporate its Lumada Internet of Things platform into the test to aid its data collection efforts and continue to build commercial products.

It's also noteworthy, that it is not Mizuho's first time testing a blockchain platform for the use case, as the firm recently completed a trade finance trial with several organizations.

Chinese Miners to Fall Victims of Ransomware

In China, a ransomware spreads, victims of which are Bitcoin miners. The damage from its activities is measured in tens of thousands of dollars. This is reported by Trustnodes.

The virus infects miners, released by Bitmain, and requires you to send 10 bitcoins, otherwise threatening to cause overheating of the device.

The problem is solved by formatting the SD card of the infected device, however, as Trustnodes notes, the whole process can take up to four days, while malicious software rapidly spreads to the other miners.

Probably, the virus comes with an "improved" firmware for miners. Some owners install such firmware to “overclock” their ASIC devices and improve their performance.

The first messages about the virus refer to August last year. In particular, Antminer S9, T9 and even L3 + for Litecoin were attacked. Over time, the malware has been improved. Now its distributor himself can decide when to display a message requesting a ransom. One miner also said that one night the address to which the 4,000 devices belonging to him sent the mined cryptocurrency was changed to the address of the hacker, which brought him $ 8,000.
