Blockchain: What It Is, How It Works

Efficiency, innovation, and cybersecurity are the three priorities on which much of the attention of companies is focused today. In all of these, the blockchain application can “make a difference.” We see below a brief explanation of what the blockchain is, how it works, and the main application areas.

What Is The Blockchain, A Simple Explanation

The definition of blockchain is now well known. It is a distributed database. A transaction log where data is not stored on a single computer but multiple machines connected via the Internet. The connection is made through a dedicated application that allows interfacing with the “chain,” made up of blocks of data that store transactions. To be consolidated within a block, each data, and subsequently each block before being inserted into the “chain,” is subjected to a validation process.

How The Blockchain Works

Before continuing, we want to dive more deeply into two terms: blockchain hubs and diggers. The first is the organization’s PCs that have downloaded the blockchain into their memory. Anybody can turn into a corner through the proper program (Bitcoin Core, for instance, for Blockchain Bitcoin). The diggers are the ones who complete this exchange. They utilize solid PCs and a reasonably intricate approval convention (clarified later). 

The work is compensated with a prize. The now-normal term for this activity is “sabotage,” the English expression to mine, that is to remove. The approval convention (which characterizes the approving calculations and who can be a digger) consequently addresses the super essential component of the blockchain. It is definitively on this that the speed of the chain and its well being significantly depend. 

The calculations that oversee this cycle approve that each new section meets explicit rules and keeps information currently in the chain from being messed with. This way, the primary advancements are seen around here, and blockchains vary according to a mechanical perspective. Nonetheless, it is fundamental to bring up that one convention isn’t better than another. The utilization of either additionally relies upon the kind of use the blockchain is utilized for.

The Difference Between Public (Uncommissioned Or Permissionless) And Private (Permissioned) Blockchains

Finally, we remind you that if the blockchain was born as a public way to carry out transactions (these are the so-called unpermissioned or permissionless blockchains to which anyone can access), Blockchain 2.0 sees the spread of this technology (in areas other than cryptocurrencies) more and more internally. Of more or less closed ecosystems, with the consequent birth of private blockchains (called permissioned because they require a specific authorization to access them). The latter is often the result of the creation of consortia for particular supply chains. 

We can therefore say that we have:

  1. Public blockchains: anyone can access and transact or participate in the validation process. Bitcoin and Ethereum are the most famous examples of public blockchains.
  2. private blockchains: controlled by a single organization that establishes who can join it, who can transact within it, and participate in the consent/validation process
  3. Blockchain consortia: the authorization process is delegated to a preselected group (among the main consortia, there is, for example, R3, which groups the largest banks in the world). The possibility of joining the blockchain and operating transactions can be public or limited to participants only. This type of permissioned blockchain is particularly suitable for use in the business world.
