The core advantage of blockchain technology is that it does not require a traditional centralized organization.
What Are the Prospects of Using a BlockChain?
It has obvious advantages, but also has shortcomings and deficiencies. Currently, the application of the blockchain is to achieve real landing, support the actual business, and still need to constantly improve itself on the technical level.
How Does a Blockchain Work?
Each block in a blockchain network stores some information along with the hash of its previous block. A hash is a unique mathematical code which belongs to a specific block. If the information inside the block is modified, the hash of the block will be subject to modification too. The connection of blocks through unique hash keys is what makes blockchain secure.
Do you can describe how the transaction is going on?
Yes.
In a nutshell, here’s how blockchain allows transactions to take place:
1. A blockchain network makes use of public and private keys in order to form a digital signature ensuring security and consent.
2.Once the authentication is ensured through these keys, the need for authorization arises.
3.Blockchain allows participants of the network to perform mathematical verifications and reach a consensus to agree on any particular value.
4.While making a transfer, the sender uses their private key and announces the transaction information over the network. A block is created containing information such as digital signature, timestamp, and the receiver’s public key.
5.This block of information is broadcasted through the network and the validation process starts.
6.Miners all over the network start solving the mathematical puzzle related to the transaction in order to process it. Solving this puzzle requires the miners to invest their computing power.
7.Upon solving the puzzle first, the miner receives rewards in the form of bitcoins. Such kind of problems is referred to as proof-of-work mathematical problems.
8.Once the majority of nodes in the network come to a consensus and agree to a common solution, the block is time stamped and added to the existing blockchain. This block can contain anything from money to data to messages.
9.After the new block is added to the chain, the existing copies of blockchain are updated for all the nodes on the network.
