BLOCK CHAIN TECHNOLOGY
LINK
The blockchain technology is a system that enables the transparent record keeping. It is called as the back bone of the cryptocurrencies. The block chain technology is a ledger that hava the records of the transactions across a lot of computers in that way the transections which are registered cannot be changed. This creates a sense of security of all the transactions. This term derived from the data structure and the information in the blocks and these are Linked together.
KEY COMPONENTS OF BLOCKCHAIN TECHNOLOGY
Every block consists of a list of the transaction. The block is added to the chain when it is filled with the data. Each block consists of a identifier which is called as the hash and it is created with the use of cryptographic algorithms. This identifier is a digital type of fingerprint of the block.
The nodes are the computers that takes part in the network of blockchain technology. Each computer has a copy of the blockchain it ensures that all the transactions are verified and ensures that it has recorded across the blockchain.
The network must reach a consensus in order to add a new block to the blockchain technology. The different mechanisms are used for the different blockchains . The most common is the PoW and PoS. In the proof of work, the complex mathematical problems are solved by the miners for the validity of the transactions.In proof of stake, on the basis of the no of the coins the validators are selected.
HOW BLOCKCHAIN WORKs
Link
When a transaction is started, it is transmitted to the network. After that, the nodes present in the network verify the transactions.
STEPs
- Transaction initiation
In this step, the transaction is initiated.
- Verification
The transaction is verified by the nodes.
- Block Creation
After the verification of the transaction these are bundled together into a block.
- Consensus
The network attain a consensus on the new blockchain with the use of the consensus methods.
- Addig to chain
In this step, the new block is added to the previous blockchains. And in this step the transaction became permanent.
- Updating the ledger
The copies of the blockchains are updated by the computers and can be accessible to the participants.
