Blockchain development is going strong at some of the most significant companies on the planet.
Here are just a few massive names that use blockchain technology.
Apple filed a patent back in December 2017 that details a blockchain system designed to create and verify timestamps.
“Attempted alteration of the blockchain by a malicious node regarding the time value will be detected by honest nodes.”
This could fight cyber attackers and also certify digital signatures.
Apple stated that “The new time becomes part of a blockchain when a miner solves the hash puzzle related to the new block holding the transaction indicating the new time. Because of distributed consensus, attempted alteration of the blockchain by a malicious node regarding the time value will be detected by honest nodes.”
The patent describes a program that creates a secure timestamp on a blockchain ledger.
Google is already known as one of the world’s most important buyers and investors in blockchain startup companies, and now the tech giant is working on its own blockchain protocol.
According to Bloomberg, the Alphabet Inc. unit is currently developing its very own distributed digital ledger that third-parties can use to post and verify transactions. Google’s plans include differentiating its cloud services from the rivals.
IBM is at the top of mainstream corporate blockchain adoption. The company just flaunted a chip that it says is the world’s smallest computer that will help companies use the blockchain to verify the authenticity of the products from a particular supply chain.
IBM uses a blockchain based on Hyperledger Fabric, and it stated that it had already delivered distributed ledger services to more than 400 clients all over the world from areas such as banking, logistics, healthcare and the government as well.
The giant is teaming up with the U.S. State Department to develop a blockchain ledger that will eliminate forced labor throughout the world.
According to Reuters, Coca-cola is already exploring multiple blockchain projects.
These are only of a few of the most prominent brands that are building on the blockchain these days.
