At its heart, the word “blockchain” simply signifies the distributed ledger system that runs all currencies in the world. Block chains are an account of transactions between two people on the Internet, the buyer and the seller. The problem in traditional ways of keeping track of transactions is that they are susceptible to hacking and duplicates and rendering the data unreadable. With blockchains, data is unreadable until the data is stored elsewhere on the same system.
The term “blockchain” is a collective of Internet computer networks. It can also refer the protocols and the software used to manage these networks, also known as blockchains. Blockchains come in different forms. Proof of Computation (PC) or Byzantine Agreement are types of blockchains that are used by Internet networks like Bitumen and the Linux upstream network. Distributed Ledger Technology (DLT), which uses multiple chains, is a different well-known type of blockchain.
Blockchains in fact, aren’t really networks. They’re more like databases. Imagine the difference between a phonebook and your local grocery store in that one you use to find groceries and the other one is for transactions. The technology works exactly the same. The only difference is that each manages and stores its data while the other one manages all computers that are that are involved in transactions.
The main difference between the two systems is that the latter works on the basis of a “hash table” whereas the former is a proof-of-work (PoW) system. A hash function takes a message and checks it against previously-considered transactions that have been programmed into the ledger. The result is an unique hashcode which indicates the state of the ledger after the work has been completed. The verification that the message is consistent with the records shows that a particular transaction occurred.
So what does the term “blockchain” refer to? It can be used loosely to define numerous concepts in the area of distributed ledger tech. Distributed ledgers are networks that are partially or wholly linked together using ledgers that are mathematically linked together. A fully connected ledger, by definition, is not hacked because there would have to be an attacker who would be capable of taking the control of any one of the linked blocks and alter the ledger’s status from an unalterable state to one that could be easily altered.
There are several distinct characteristics of the word “blockchain” brings with it. First, it refers to the ledger in which the transactions occur. In addition to the ledger itself, the ledger must be kept in sync, which is achieved through the inclusion of a proof-of-work (PoW) algorithm at every point in the chain. Although most experts would agree that the PoW algorithm serves the purposes of making sure that the blocks are correctly laid out and free of errors, some disagree. What this means is that not everyone believes that all the chains are updated at the same time and this could result in inconsistencies in how the ledger on the network is accessed and altered.
Another characteristic of the term blockchain is its association with distributed ledgers such as those used within the Hyperledger project. The Hyperledger project, which is an open source project, was originally intended for banks and other major financial institutions. Many prominent cryptologists believe that “blockchain” can be used to mean various technologies and systems. This includes those that make use of currencies, stocks licensing resources, and smart contracts.
Digital ledgers, in their most basic form, is simply a digital repository that keeps track of various transactions. The digital ledger can be used to facilitate any kind of transaction that happens through the internet. However it isn’t limited to the above-mentioned transactions. It is one of the most adaptable and complex forms distributed Ledger technology. This is why it is increasingly being used across the globe. Understanding how the modern-day global economy works and the role the digital ledger has in this, is something that all people should be thinking about particularly when considering the future of global communication.
