Blockchain Technology

What is Blockchain Technology ?

From a cruising altitude, a blockchain might not look that different from things you're familiar with, say Wikipedia.With a blockchain technology, lots of people can create entries in an information record, and an online community of users can control how the information record is modified and updated. Likewise, Wikipedia entries are not the product of a single publisher. No one manages the information.However, when descending to ground level, the differences that make the Blockchain technology unique become clear. While both are run on distributed networks (Internet), Wikipedia is integrated into the World Wide Web (WWW) using a client-server network model.A user (client) with the necessary permissions associated with your account can change Wikipedia entries stored on a centralised server.

Each time a user accesses the Wikipedia page, he obtains the updated version of the 'master copy' of the Wikipedia entry. The total control of the database remains with the administrators of Wikipedia. All other authorisations, such as access and permits, are maintained by a central authority.The digital backbone of Wikipedia is similar to the highly protected and centralised databases that governments, banks or insurance companies maintain today.

The shared database generated by the blockchain technology has a fundamentally different digital backbone network. This is also the clearest and most prominent feature of blockchain technology.The "master copy" of Wikipedia is edited on a server, and all users see the new version. When it comes to a blockchain, every node in the system transfers the same result, each one updating the record individually, with the most popular record turning into the de facto official record rather than having a master copy.

Definition of Digital Confidence

In the case of blockchain technology, private key cryptography provides a powerful property tool that meets authentication requirements. The possession of a private key is property. It also prevents a person from having to share more personal information than they would need for an exchange, leaving them exposed to hackers. Authentication is not enough Authorization is: having enough money, transmitting the correct type of transaction, etc., you need a network distributed point by point as a starting point. A distributed network reduces the risk of corruption or centralized failure.

This distributed network must also commit to recordkeeping and the security of the transaction network. The authorization of transactions is the result of the whole network applying the rules for which it was designed (the blockchain protocol). Authorization and authentication provided in this way allow interactions in the digital world without relying on (expensive) trust. At present, entrepreneurs from industries around the world have realized the implications of this development: unimagined, new and powerful digital relationships are possible. Blockchain technology is often described as the backbone of a transaction layer for the Internet, the basis of the Internet of Value.

In fact, the idea that cryptographic keys and shared accounting books can encourage users to protect and formalise digital relationships has an imagination that is going crazy. Everyone, from governments to IT companies and banks, is looking to build this transaction layer. Authentication and authorization, vital for digital transactions, are established as a result of the configuration of the blockchain technology.The idea can be applied to any need for a reliable registration system.

Applications of Blockchain Technology

At present, many SMEs make use of blockchain technology to generate greater transparency and precision in the digital information ecosystem, and they are driving knowledge of technology in segments starts from infrastructure to public policy.

Banking

Banking

Banking is just the beginning. However, from a macro perspective, banking institutions function as critical stores and value transfer centres. As a digitised, secure and tamper-proof ledger, blockchain might serve the same function, injecting better precision and exchange of information into the economic services ecosystem.

Voting

Voting

Elections need authentication of voter identity, preservation of secure records to monitor votes and confidence counts to decide the winner. Sooner or later, blockchain tools could function as an integrated infrastructure for casting, tracking and counting votes, potentially reducing the need for counts by taking electoral fraud and dirty play off the table.

Cloud Computing

Cloud Computing

Blockchain-based processing projects such as Golem are allowing users to rent their CPU capacity and be rewarded with tokens. Similarly, Ethereum has been informally called the "global supercomputer" because of its ability to execute smart contracts, and its mining exploitation is resistant to ASIC ( which allows everyday PC owners to compete proportionally with large mining operations).

Cloud Storage

Companies that offer cloud storage often protect customer data on a centralised server, which can mean greater vulnerability of the network to hacker attacks. Blockchain cloud storage options allow for decentralised storage and, for that reason, are less prone to attacks which will cause systemic harm and extensive data loss.

Supply Chain Management

Supply Chain Management

One of the most globally relevant features of blockchain is that it allows more secure and transparent control of transactions. Supply chains are fundamentally a set of transaction nodes that are linked to move products from point A to the point of sale or final implementation. With blockchain, as products change hands in a supply chain from manufacturing to sales, transactions can be documented in a permanent decentralised register, which reduces delays, additional costs and human errors.
