The Features of Blockchain
A few key features of Blockchain are as follows:
- Distributed – As the ledger happens to be spread all across the network, tampering is not possible.
- Peer to peer – There is an absence of a central authority in Blockchain to manipulate or control it. Every participant does interact with each other directly and so, you can exchange data with third-parties directly.
- Blockchain is secured cryptographically – Cryptography is utilized for the security services and it turns the ledger tamper-proof.
- Add-only – You can data in blockchain through time-sequential order, and this feature implies that when data is included to the blockchain, then it becomes nearly impossible to alter that data. Thereafter, it is viewed as practically immutable.
- Consensus – It is considered the most critical feature and it provides blockchain with the capability to make the ledger updated through consensus.

The Working Method of Blockchain
At a time when a block does store novice data, then it is included to the blockchain and as the name suggests, blockchain comprises multiple blocks that are strung together. For making a block included in the blockchain, you must keep in mind four things which happen like:
A transaction ought to occur. After you click through several checkout prompts, you end up making a purchase.
The transaction should be verified. Post making that purchase, it becomes very important to verify the transaction. With various other public records of info, such as Wikipedia, Securities Exchange Commission, and local library, there is someone who takes charge of selecting new data entries, and with blockchain, that task is left to the network of computers.
The transaction should be stored in a block. When your transaction has been confirmed as appropriate, then it receives the green light. The Amazon’s digital signature, the dollar amount of the transaction, and your signature get stored in a block and there, the transaction is supposed to join hundreds or even thousands.
The block should be provided with a hash. When the block’s transactions get verified, then it ought to be provided with an exclusive identifying code which is known as a hash. Additionally, the block will be provided with a hash of the recent block which is included to the blockchain, and when it is hashed, then the block can be included to the blockchain.
After the new block gets included to the blockchain, the block becomes publicly obtainable for every person to view.
