A Blockchain is a digital list of records that is called blocks. These blocks are linked with each other by using the cryptography technique. It is managed via a Peer-to-Peer network which is used as a publicly distributed ledger. Blockchain is a kind of platform where people can exchange values and transactions without the interruption of any centralized body, like RBI ( Reserve Bank Of India).
For Example: If there is a person A who wants to transfer funds to person B then the details of the transaction, along with other key information, are processed into a block. This block also contains a password or a public key that every node has access to, and a private key that only Person A has access to.
Blockchain is a digital transaction record that is cloned and distributed across the entire network of computer systems. In this Blockchain system, each block contains several transactions in the chain and when a new transaction occurs in the Blockchain, that transaction record is being added to every participant’s ledger.
Blockchain is a system of recorded information that is impossible to change, cheat, or hack the system. If there is an interruption in one block in one chain then it would immediately showcase that it has been tampered with. It is a useful technology that is used for transactions of the values without the interruption of any centralized body.
DLT stands for Digital Ledger Technology which is a common database where several nodes are handled by many participants.
Blockchain is a kind of DLT where the recorded transactions are collected with a fixed cryptographic signature called the hash.
On January 9, 2009, Satoshi Nakamoto introduced "Bitcoin: A Peer-to-Peer Electronic Cash System." Bitcoin is a type of digital currency that can be used to transfer values or transactions, without a central bank or single administrator. It can be sent from peer-to-peer from one user to another via a peer-to-peer Bitcoin network, without the need of a central bank.
Bitcoin is a digital currency that circulates without the interruption of any government. It circulates free from any central authority or government. Apart from this, it relies on peer-to-peer cryptography software. A public ledger records of all Bitcoin transactions and their duplicated copies are placed on servers all around the world.
As discussed, it is impossible to hack, change, or cheat the system. If there is an interruption in one block of one chain it would be immediately brought to the user’s attention. For Example: If any hacker has an intention to hack the Blockchain system then they can't change every single block in the chain. They will have to make sure about every single block across all the distributed versions of the chain.
Have you heard about Bitcoin and Ethereum? Well, Bitcoin and Ethereum are the most popular cryptocurrency that continuously growing as blocks. These coins are being added to the chain and will be added as the security of the ledger.
Now Blockchain technology can be used and combined into multiple sectors. The main use of Blockchain technology is to work as a distributed ledger for cryptocurrencies such as Bitcoin or Ethereum. The use of Blockchain technology for an individual has also greatly increased since 2016.
Blockchain technology is being used for creating a permanent, public, transparent ledger system for collecting the data by digital tracking, sales, and content creators payment including musicians or wireless users.
Bitcoin is considered transparent and decentralized. If any hacker attacks your system or tries to breach, they would ask for money in Bitcoin. Cryptocurrencies are transparent and decentralized so it is easier for anyone to hide their identity. The reason hackers want money in Bitcoin is that they can easily hide their identity and convert Bitcoins into money.
There have been many attempts in the past to create digital money, but as result, they have always failed. The main issue is gaining trust. People are concerned to use a new currency owing to anxieties regarding data theft. Taking this into consideration, Bitcoin designed its system to solve this particular problem by using a specific type of database system called Blockchain. In most normal databases, a third party can change the transaction entries. Blockchain is completely different from any other database as it is run solely by the people who use it and only the user has complete access to and control over his/her transactions.
