Decentralization
Transparency
Immutability
Consensus Mechanisms
Smart Contracts

Decentralization

Unlike traditional centralized systems, blockchain operates on a decentralized network. This means there is no single point of control or authority, and every participant has a copy of the entire blockchain.

This decentralized nature enhances security by eliminating a single point of failure and making it more resilient to attacks.

Transparency

The blockchain is a transparent system where all transactions and changes to the ledger are visible to all participants.

This transparency helps to establish trust among participants as it allows for easy verification and auditing of transactions. Additionally, it reduces the potential for fraud or manipulation since any changes made to the blockchain can be easily traced.

Immutability

Once information is recorded on the blockchain, altering or tampering with it becomes nearly impossible. Each transaction or data entry is cryptographically linked to the previous one, creating a chain of blocks.

Any attempts to modify a block would require altering subsequent blocks and gaining control of most of the network’s computing power, making it highly impractical and computationally expensive.

Consensus Mechanisms

Blockchain relies on consensus mechanisms to validate and agree on the ledger’s state. Different consensus mechanisms, such as Proof of Work (PoW) and Proof of Stake (PoS), ensure that all participants reach a consensus on the validity of transactions.

This consensus mechanism adds another layer of security by preventing malicious actors from manipulating the ledger.

Smart Contracts

Blockchain technology allows for the execution of programmable agreements known as smart contracts. These self-executing contracts automatically enforce the terms and conditions encoded within them.
