How Does Blockchain Work? A Simple Guide

Blockchain technology has become a buzzword in recent years, but how does it actually If there is one buzzword that has been making rounds during recent years, then blockchain would be the name. But what is it? The very basic substance is that blockchain is a decentralized, security way of recording transactions. It holds the key to change in industries from finance to supply chain management. This post from Dex-Trade Academy breaks down the basis of blockchain technology into an entertaining, easy-to-understand block.

What is Blockchain?

A blockchain is more or less a digital record of transactions across a network of computers. Blockchains, however, differ from typical databases in that no single entity is in control due to the decentralized nature. This makes blockchains not only highly secure but also transparent and fits well for a number of use cases.

How Does Blockchain Work?

1. Blocks and Chains

A blockchain is a chain of blocks, each linked to its predecessor and successor. Each block consists of the list of transactions involved, the timestamp, and a unique identifier depending on the hash. Every new transaction that's occurring goes into a block with all the other transactions that are occurring. Once the block has been completed, then it becomes added to the chain.

2. Decentralization

The critical thing in blockchain data is that it is not stored on one server but distributed across the nodes of computers. Each node holds a copy of the whole blockchain, meaning data is transparent and cannot be tampered with without an agreement from the majority of the network.

3. Consensus Mechanisms

The network decides on the addition of a new block once the transactions within the block are deemed valid. It makes this decision by some consensus mechanism, which is with the help of PoW or Proof of Stake. In PoW, the powerful computer system solves complex mathematical problems for the validation of transactions and adds new blocks. In Proof of Stake, validators are selected to create a new block based on the amount of cryptocurrency a person can hold and "stake" for a block.

4. Immutability and Security

The immutability of blockchain would guarantee that any block that is added to it may hardly be changed. Once the data is part of the blockchain, sublicense manageable, and tamper-proof it becomes. While changing a block, for instance, one may have to change the data in the subsequent blocks, which is computationally very unfeasible for most of these networks.

Applications of Blockchain

• Cryptocurrencies: The most well-known applications of blockchain technology come through Bitcoin and Ethereum. They realize an open-source, decentralized, secure way of transferring digital assets.

• Supply Chain Management: It helps trace the product journey all the way from its origin to the consumer. This adds to the element of transparency and lessens frauds

• Smart Contracts: A contract that is self-executing based on an agreement written into lines of code. The contract is automatically enforced when certain conditions are met, thereby reducing dependence on intermediaries.

Conclusion

But blockchain is more than the technology powering cryptocurrencies. The inherent security, transparency, and decentralization of the way it records data make it potentially disruptive to a number of industries. Once you understand how blockchain works, a world of possibilities opens up.
