Inside
Blockchain, security in the new millennium

Computer security will be revolutionized by Blockchain

The arrival of blockchain has brought a new standard of sharing information, destined to revolutionize the IT world and many topics related to the business one like the concept of trust, transparency and security.

It could also have important repercussions in politics. Many companies have started launching pilot programs and real projects based on this new technology applied to different fields, from finance to health care, from online payments to logistics, supply-chain management and global shipments.

A Blockchain is a continuously growing list of records, called blocks, shared among all users. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. Despite being quite recent, this technology is getting very popular among corporations.

One of the first Blockchain’s applications is Bitcoin, which dates back to 2008. Its creator, Satoshi Nakamoto (probably a pseudonym for one or more developers), conceived in his article: “A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution”. Today blockchain has a broad range of applications. It’s not a single technology but a complex network architecture that allows non-coordinated clients to make transactions and keep an unchanging and secure book.

For example, an interesting application concerns the smart contract, scripts that are automatically made when certain conditions are satisfied. Different users can create contracts that need more than one set of input to make a transaction. For example, contracts for the sale of immoveable property need signatures of who’s buying, who’s selling and the respective financial institutions.

PC Cube tries to get the most out of Blockchain’s potentialities and innovation to develop a decentralized application that can protect a company’s security and the uniqueness of their software licenses. In a market where almost 40% of all installed software in the world doesn’t have a valid license, their management represents one of the worst critical issues for small and medium companies.
