2. Technical Aspects of Blockchain Technology

Using blockchain technology, transactions can be recorded securely and transparently across a network of computers. It is decentralized and uses a distributed ledger that is held by each node in the network. The foundation of this technology is encryption, which guarantees the integrity of all financial dealings.

Blockchain technology’s nitty-gritty components include consensus methods, cryptographic hash functions, and smart contracts. Validating transactions and ensuring that all nodes in the network agree on the latest state of the ledger are performed via consensus methods. Data integrity on the blockchain is protected by cryptographic hash algorithms. The blockchain can be used to hold smart contracts, which are contracts that can execute themselves when specific criteria are satisfied.

Due to its distributed nature, blockchain technology is difficult to compromise or corrupt. By cutting out financial institutions and banks as middlemen, transaction times and costs can be reduced. The financial sector, healthcare, and the logistics industry are just a few that stand to benefit greatly from blockchain technology. Nonetheless, it is still in its infancy, and a number of technological hurdles must be overcome before it can be widely embraced.

2.1. How does blockchain technology work?

Transactions are recorded in a distributed digital ledger called a blockchain that exists across a network of computers. A hash is a unique code used to verify the integrity of data stored in each block of the chain. No block in the chain may be modified or removed without invalidating the entire ledger. A distributed network of nodes, each of which stores its own copy of the blockchain, validates transactions. Changes to the ledger would be promptly picked up by the other nodes, making it practically difficult to hack or manipulate the system. In sum, blockchain technology is perfect for many uses since it facilitates transactions in a secure and transparent manner.

2.2. Components of a blockchain

A blockchain is a decentralized, encrypted distributed ledger. Several parts come together to form a whole that serves its purpose. The first part is the block, which includes the confirmed transactions and is appended to the blockchain. Each brick is connected to the one before it, creating a chain. The network is the second part of a blockchain system and consists of the interconnected nodes that verify transactions and keep the chain secure. The third part is the consensus mechanism, which is what’s utilized to get everyone on the network to agree on what the blockchain’s current state is. Finally, the self-executing contract stored on the blockchain and utilized to automate the execution of business activities is the smart contract, the fourth component.

2.3. Types of blockchain

There are three distinct categories of blockchain systems: public, private, and consortium.
Public blockchains are both decentralized and transparent because anybody may join and validate transactions. Private blockchains, on the other hand, are only accessible to a select few users and are kept in-house for operational reasons. Consortium blockchains, which include a collection of companies coming together to build a network and confirm transactions, are a hybrid of public and private blockchains.
Each blockchain implementation has its own set of benefits and drawbacks; picking the best one relies on the needs at hand.

2.4. Consensus algorithms

To guarantee the safety and dependability of blockchain technology, consensus algorithms play a significant role. These algorithms are in charge of verifying the integrity of the ledger and the legitimacy of any modifications made to it across the network.

Each of the several consensus algorithms in use in blockchain technology has its own set of advantages and disadvantages. Proof-of-Work (PoW), Proof-of-Stake (PoS), Delegated Proof-of-Stake (DPoS), and Byzantine Fault Tolerance (BFT) are all examples of popular consensus algorithms.

Bitcoin and Ethereum, two of the most well-known cryptocurrencies, both use PoW as their consensus mechanism. To add new blocks to the blockchain, miners must solve difficult mathematical puzzles and are rewarded in cryptocurrency if they succeed. When using PoS, validators must have a particular number of coins in order to take part in the consensus process. Similar to Proof-of-Stake (PoS), Delegated Proof-of-Stake (DPoS) allows token holders to elect delegates to validate transactions on their behalf without requiring validators to possess cryptocurrency. Some enterprise blockchain systems employ BFT, a more complicated algorithm that is supposed to be more fault-tolerant than other consensus methods.

In the end, the consensus algorithm used for a blockchain network will be determined by its requirements and intended function. Choosing the wrong algorithm can lead to inefficiencies, security holes, and other problems, so it’s crucial to weigh the pros and downsides of each option.

2.5. Smart contracts

One of the most crucial technological features of blockchain is smart contracts. These contracts are self-executing, meaning they are set up to run automatically once certain criteria are met. They are transparent and immutable because of their storage on the blockchain, making them useful in many contexts. The widespread adoption of smart contracts has the potential to dramatically alter several economic sectors by cutting out middlemen while simultaneously boosting efficiency and saving money. They have a wide range of potential applications, including process automation, identity management, payment processing, and more.
