What Is Blockchain?

Basically, a blockchain is a time - a set of invariable records managed by computers that do not belong to a single company. Blockchain technology has gained attention in recent years as digital information is disseminated and not copied. While blockchain has become mainstream and a buzzword for bitcoin and other forms of cryptocurrencies, its potential goes much further.
Blockchain is a growing list of data sets, known as blocks, that are linked by cryptography. These blocks are secured and connected to each other according to the cryptographic principles of a chain.
It is an open, distributed register that can efficiently record transactions between two parties in a verifiable and permanent way. It is a decentralized, distributed and public digital register used to record transactions on many computers without changing the records.
Anyone who has followed banking, investment, and cryptocurrencies over the past decade knows the concept of blockchains and record - that is, the storage of technology in general. In the language of the cryptocurrency, a block is a new transaction, which could mean a vote on the record or a vote on a record.
The good news is that blockchains are actually easier to understand than the definition sounds. At its most basic level, a blockchain is literally just a chain of blocks or blocks. When we use the word "block" or "chain" in this context, we are talking about a public database or chain in which all digital information is stored in a block.
Simply put, a blockchain is a time series - a series of invariable records managed by a cluster of computers that do not belong to a single company. In this article, we will explain what blockchain technology is, what its properties are and what makes it so unique.

A data block (i.e. a block) is secured and connected to each other by cryptographic principles (e.g. chains).
Once a block or several blocks are linked at the same time, the stage is set for creating a peer-to-peer ledger (blockchain) that could record transactions on a global scale. The platform is managed by autonomous global users who use peer-to-peer networks, using time - the servers that conduct and approve financial transactions (currency first) and the users themselves. This gives blockchain a democratization factor: a digital computing platform that allows users to conduct transactions without a central authority calling the shots and no one charging fees or fees for those transactions. Blockchain was marketed by companies such as Bitcoin, Ethereum, Bitcoin Cash and Ethereum Classic.
Originally developed as a technology for Bitcoin, blockchain has become famous in recent years for its ability to create a vast, globally distributed register that runs on millions of devices and records everything of value. It is essentially a distributed transaction account, the identical copies of which are maintained on a network of member computers. Shortly after its creation, Bitcoin (the world's most popular digital currency) soared to $2 billion, putting more focus on blockchain and bitcoin technology.
Transactions are recorded and grouped in blocks, each block representing a certain percentage of the total value of all transactions in that block.
Cryptography protects the connection between the block and its contents, so that previous transactions cannot be destroyed or forged. Every transaction on the blockchain network is approved by thousands or millions of computers, removing human error from the process.
Because each block has a unique hash and is verified by a huge computer network, it is extremely difficult to change information without changing the entire blockchain. Even if a computer makes a mistake, the bug affects only one copy of the blockchain, and it updates that copy every time a block is added, making blockchain difficult for it to modify or manipulate.
Unlike distributed databases, where a single company distributes, manages and controls the data, blockchain allows distributed control, unlike a distributed database, where it is distributed and managed and controlled by a single company. Different people and institutions that do not trust each other share information without the need for a central administrator. Because the register records transactions on many computers, the blockchain data cannot be altered.
Blockchain is a distributed register of transactions managed by a decentralized computer network in a peer-to-peer (P2P) network. The decentralised database is managed by computers belonging to the peer-to-peer network (P 2P), and each independent node has a register containing all transactions ever made that can be verified.
To prevent a single point of failure (SPOF), each computer on the distributed network keeps a copy of the register, and this copy is updated, validated, and re-validated at the same time.
