This week Google made known about two separate Blockchain projects it is working on: a “tamper-proof” auditing system and a cloud operations platform.
According to a patent originally filed in September 2017, plans are underway to create a so-called “tamper-evident” ledger on the basis of Blockchain.
At the same time, Google’s Alphabet Inc. conglomerate is looking to utilize the technology to create a transparent audit review platform, Bloomberg reported March 21 citing anonymous sources at the company.
