Blockchain is a technology that ensures secure and transparent record-keeping in a decentralized manner. Operating on a network of computers (nodes), transactions are grouped into blocks and linked, forming an immutable chain. This guarantees the integrity and transparency of data across the entire network.

Centralized Exchanges (CEX) play a pivotal role in the cryptocurrency ecosystem by providing platforms for users to trade various digital assets. Unlike decentralized exchanges, CEX relies on a centralized authority to facilitate transactions and manage user funds.

Decentralized Exchanges (DEX) represent a pivotal application of blockchain technology, transforming traditional financial systems. Unlike centralized exchanges, DEX operates on a decentralized network, leveraging the principles of blockchain to facilitate secure and transparent trading.

NFTs (Non-Fungible Tokens) have revolutionized the digital landscape, offering unique ownership of digital assets through blockchain technology. From art to gaming, NFTs have expanded their applications, providing creators and enthusiasts with innovative opportunities.

Smartcontracts are self-executing contracts with coded terms, enabling automated and trustless execution of agreements on blockchain platforms. These contracts operate without the need for intermediaries, providing efficiency, transparency, and security.

Tokens are digital assets created on a blockchain. They play a crucial role in decentralized applications (DApps) on platforms like Ethereum. Tokens can be used for governance, voting, and facilitating transactions within the DApp. Transactions are recorded on the blockchain, providing transparency and traceability.

Decentralized Oracles play a crucial role in the blockchain and smart contract ecosystem by providing reliable real-world data to decentralized applications (DApps). Unlike centralized oracles, decentralized oracles operate without a single point of control, enhancing the security and trustlessness of the data they deliver.

Proof of Work (PoW) is a consensus algorithm used in blockchain networks to achieve agreement on the state of the ledger. It involves participants solving complex mathematical puzzles to validate and add new blocks to the blockchain.

Proof of Stake (PoS) is a consensus algorithm used in blockchain networks to achieve agreement on the state of the ledger. It relies on validators who are chosen to create new blocks based on the amount of cryptocurrency they hold and are willing to 'stake.'
