What is blockchain? What is crypto? Here’s what you need to know about blockchain and cryptocurrencies. A quick explanation by Think & Free. A blockchain is a system that maintains a record of transactions made in bitcoin or other cryptocurrencies through several computers connected to a network. Blockchain can be defined as a tangible or intangible asset. That facilitates the transaction reporting and asset tracking of a business network.

It is acknowledged that the cryptographer David Choum. He proposed a blockchain-like protocol for the first time in his 1982 dissertation. The first decentralized blockchain was conceived in 2008 by Satoshi Nakamoto. Any linked block from the so-called blockchain record can not be modified without subsequent modification. A unique feature is that a blockchain database is automatically managed using a peer-to-peer network and a distributed timestamping server. 

It is possible to identify several existing layers in a blockchain?

  1. Infrastructure – Establishes and provides direct infrastructure access to customers
  1. Data – Information is stored
  1. Application – Provides a way to safely and efficiently create a harmless log of sensitive activities
  1. Networking –  information propagation
  1. Consensus – To retrieve a blockchain, a compromise is an algorithm that is more like a decentralized report than a centralized database.

Each block contains the cryptographic hash of the blockchain block. These form a chain of connected blocks. The average time it takes for a network to generate one additional block in a blockchain is called block time. For bitcoin, it usually takes 10 minutes and for Ethereum, it takes between 14 and 15 seconds. 

Here are some advantages of using blockchain

  1.  Openness & trust

Blockchain is user-friendly. It prevents two transactions from spending the same single output on a blockchain. And prevents two transactions from being changed simultaneously on a single object in the database. Trust activation can be considered one of the most cited benefits of Blockchain. While It builds trust among various entities that do not exist or have not been trusted.

  1. transparency

Transparency in cybersecurity refers to the dissemination of information, software accountability, or event response and disclosure.

  1. Security 

Blockchains, or distributed ledger technologies (DLT), are structured into data blocks based on the cryptocurrencies, which guarantee the trust of the transaction.

blockchain will be used to exchange international devices and money in the world of the future. Bitcoin and Ethereum are examples of the most popular blockchains currently in the world. A notable weakness of blockchain seems to be that the blockchain is large and the blockchain is not indestructible. It will lead to severe inefficiency in the future.

Uses of blockchain in the world

Blockchain technology can be described as a sector that can be integrated into different sectors. Although the primary use of blockchain was as a ledger for cryptocurrencies such as Bitcoin, its use in other fields today has grown significantly. Let us look at some such aspects.

Games

Blockchain technology is commonly used in video games to make money. Many live sports players are given options in the game, such as character skins or other in-game items that can be used to earn and trade with other players using the money in the game. But in some countries, this may be illegal.

 Cryptocurrencies

Blockchain technology is used to record cryptocurrency transactions. For example, both the bitcoin network and the Ethereum network are based on blockchain. Governments today have implemented mixed policies on the legitimacy of their citizens’ or cryptocurrency banks. This is evidenced by the implementation of blockchain technology in several industries, including the National Digital Currency launched by China in 2020.

Smart contracts

Blockchain-based smart contracts can be partially or fully executed without human interaction. 

  1. Financial services

One reason may be that banks are interested in this technology because of its ability to speed up office settlement systems later on. Banks tend to use blockchain in financial services to increase efficiency and reduce costs.
