THE KEY COMPONENTS OF A BLOCKCHAIN BLOCKCHAIN TECHNOLOGY CONSISTS OF 3 KEY COMPONENTS: Security

Scalability

Decentralization

THE KEY COMPONENTS OF A BLOCKCHAIN Security

Scalability

Decentralization

Blockchain technology prioritizes security through cryptographic methods such as hashing, digital signatures and consensus algorithms to prevent any tampering or alteration of data. Scalability refers to a blockchain network's ability to handle a high volume of transactions efficiently, which can be a resource-intensive process and a significant challenge for many networks.

Blockchain is decentralized, with a network of independent nodes maintaining and verifying the system, making it secure and resistant to hacks and censorship.

HOW DOES BLOCKCHAIN WORK? TO UNDERSTAND HOW BLOCKCHAIN WORKS, LET'S KNOW KEY STEPS: Transaction Creation Block Formation

Verification & Validation Blockchain Security

Consensus & Block Addition

UNDERSTAND HOW BLOCKCHAIN WORKS Transaction Creation

An exchange of assets or information on a blockchain is represented by a transaction. The sender's address, the recipient's address, and the transfer amount are all included when a participant starts a transaction.

Verification & Validation

Block Formation

The network must confirm and validate a transaction after it has been created. As part of this process, multiple nodes on the distributed ledger network independently verify the veracity and accuracy of the transaction.

Blocks of transactions that have been validated are assembled. Based on the transactions and the hash of the previous block, each block contains a special identification number called a hash. As a result, a chronological chain of blocks is created, giving rise to the term "blockchain."

UNDERSTAND HOW BLOCKCHAIN WORKS

Blockchain Security

By using cryptography and maintaining a decentralized network, blockchain technology guarantees security. Once a block is included in the blockchain, it is very difficult to change or tamper with its contents. Blockchain technology is very immune to fraud and unauthorized changes due to its immutability.

Consensus & Block Addition

Nodes must reach consensus on a new block's legitimacy through intricate mathematical calculations before adding it to the blockchain, with participation from different types of nodes depending on the consensus mechanism.

USE CASES OF BLOCKCHAIN TECHNOLOGY BLOCKCHAIN TECHNOLOGY HAS A WIDE RANGE OF APPLICATIONS ACROSS VARIOUS INDUSTRIES. Financial Services

Healthcare

Supply Chain Management Government & public services

7

BLOCKCHAIN HAS DIVERSE INDUSTRY APPLICATIONS.

Financial Services

Healthcare

Blockchain can revolutionize the financial sector by eliminating intermediaries, providing transparent transactions, securing cross-border payments, and automating contracts to increase efficiency and lower costs. Blockchain enhances patient privacy, data security and interoperability in healthcare. It securely stores and shares medical records, improves clinical trials and research and prevents fake medicines in the supply chain.

BLOCKCHAIN HAS DIVERSE INDUSTRY APPLICATIONS.

Supply Chain Management

Government & public services

Blockchain enhances supply chain transparency by providing a verifiable record of transactions and movement of goods, enabling real-time tracking, reducing counterfeiting and ensuring ethical sourcing and efficient logistics.

Blockchain technology can enhance government operations by increasing security, transparency and effectiveness, improving voting procedures, reducing public assistance fraud and securely storing and sharing public records.

CHALLENGES OF BLOCKCHAINS Blockchain technology has a lot of potential, but it also has some difficulties. Regulatory Challenges Scalability

Energy Consumption

Lack of Standardization

10

BLOCKCHAIN HAS POTENTIAL, BUT ALSO HAS DIFFICULTIES.

Regulatory Challenges

Energy Consumption

The regulatory challenges for blockchain include lack of clarity, anonymity, smart contracts, data protection, money laundering and interoperability. Blockchain's consensus mechanism, like proof-of-work, demands ample computational power to authenticate transactions, resulting in high energy consumption, but newer technologies are seeking less energy-intensive alternatives.

11

BLOCKCHAIN HAS POTENTIAL, BUT ALSO HAS DIFFICULTIES.

Scalability

Blockchain's scalability issues stem from limited block size, high energy consumption of Proof of Work, and network congestion. Solutions include larger block size limits, alternative consensus mechanisms and layer 2 scaling.

Lack of Standardization

Different blockchain networks work differently and don't always talk to each other well, which limits the potential of blockchain technology. Creating common standards is difficult, so using blockchain can be challenging.
