Decentralization:

Decentralization is a core principle of blockchain technology. n a decentralized blockchain, every participant, or node, has a copy of the entire blockchain. This eliminates the need for intermediaries and allows for trustless transactions.

Key points:

• Decentralization ensures that no single entity has complete control over the blockchain, making it more resistant to manipulation or censorship.
• Transactions on the blockchain are verified and validated by consensus among network participants, rather than relying on a central authority.

Consensus Mechanisms:

• Consensus mechanisms are protocols that enable participants in a blockchain network to agree on the validity of transactions and achieve consensus without the need for a central authority. They ensure that all participants reach a shared agreement on the state of the blockchain.

The most common consensus mechanisms include Proof of Work (PoW) and Proof of Stake (PoS).

In PoW, participants, known as miners, compete to solve complex mathematical puzzles to validate transactions and create new blocks.

PoS, on the other hand, relies on participants' ownership of cryptocurrency to validate and create new blocks.

Consensus mechanisms play a vital role in maintaining the security, integrity, and stability of the blockchain network.

Immutability:
