Decentralization
Decentralization is the fundamental principle of blockchain and cryptocurrencies, defining a system in which power and control are not concentrated in a single entity, but are distributed between a large network of participants.
DEX (decentralized exchange)
A decent (decentralized exchange), or decentralized exchange, is a cryptocurrency exchange platform that works without centralized authority or intermediary. Unlike traditional (centralized) exchanges where you store your funds in a company, a DEX allows directly between users (peer-peer), usually through smart contracts on a blockchain.
DAO (autonomous decentralized organization)

An autonomous decentralized organization (DAO) is a digital entity, organized and collectively governed by its members, which operate on the basis of automatic rules.
Cross-Chain
Cross-Chain (or "cross-chain interoperability") refers to the ability of different blockchain networks to communicate, change data and transfer assets with each other.
Smart contract (Smart Contract)

An intelligent contract is a set of computer codes running on blockchain and which automatically executes an agreement when the conditions set are met.
Consensus

Consensus represents a mechanism by which all nodes (computers) in a blockchain network reach an agreement on valid data.
Confirmation
Confirmations are a basic element in the functioning of cryptocurrencies, and their understanding is essential for any user. From the security of transactions to the prevention of fraudulent use of funds, confirmations play a key role in guaranteeing the integrity of the blockchain network.
Public key
A public key is the visible half of the cryptographic system that allows you to interact safely with the blockchain.
Signature key (private key)

Have you ever wondered how transactions are secured in the cryptocurrency world and what gives you control over your digital funds? The answer is the sign of signature, a fundamental concept that is the basis of blockchain security.
Market capitalization (Market Cap)
Market capitalization is an essential tool for any investor in cryptocurrency, because it offers a valuable perspective on the size, stability and potential of a project.
