What is Blockchain?
Blockchain is a new way of recording information. The blockchain system is so secure that it makes it impossible to change, hack, or cheat the system. A blockchain is a kind of digital ledger. It records transactions that can be duplicated and distributed on the various computer systems across the blockchain network.
A blockchain consists of various blocks of information. These blocks can be related to each other, which may add before or after a particular block. Thus, it makes a blockchain.
Each block in the chain consists of multiple transactions. Every time a new transaction takes place, its record is added to each participant's ledger. This type of database is managed by multiple participants. It is known as Distributed Ledger Technology (DLT).
If someone tampers with a block of information, it would immediately be caught. This makes it very secure from hackers. If hackers want to change the data in the blockchain, they would have to change the data in every distributed block.
Digital currencies such as Bitcoin and Ethereum are based on blockchain and are constantly growing. As more and more blocks are being added to it, the security of it is also increasing.
How blockchain works
Whenever a transaction takes place, it is recorded as a block of data.
These transactions show the position of an asset that might be tangible or intangible in nature. Each data block is capable of recording information according to the user's choice. Such as when, where, what, how, etc.
Every block is connected to the blocks before and after it
These blocks form a chain of data. An asset moves from one owner to another, thus changing its ownership. The exact time of the various transactions is recorded in the block in a sequential manner. The blocks confirm and secure this data by linking with each other. It prevents any block from being tampered with or any block from being inserted in between.
The transactions secured together to form an irreversible chain: a BLOCKCHAIN.
Every new block that is added, adds to the strength of verification of the previous block. This, in turn, strengthens the entire blockchain. This makes the blockchain tamper-proof. This eliminates the possibility of data being manipulated by a foreign entity. This builds a blockchain into a ledger that its users can trust completely.
