Blockchain: Blockchain is a technology that aims to share data via a decentralised, distributed, and public digital ledger used to record transactions. This technology ensures that once transactions are added to the chain, they cannot be altered or deleted. 

Block: A unit of data on the blockchain that contains a bundle of verified transactions, a timestamp, and a link (hash) to the previous block.

CEX (Centralized Exchange): A traditional exchange that acts as a custodian and intermediary for crypto trading (e.g., Binance, Coinbase).

DEX (Decentralized Exchange): An exchange that allows peer-to-peer cryptocurrency trading directly on the blockchain via smart contracts, without a central custodian.

Stablecoin: A type of digital currency designed to maintain a stable value, typically pegged at 1:1 to a fiat currency like the US Dollar. Examples of stablecoins are USDC, USDT, etc.

Fiat: These are government-issued currencies that are not backed by a physical commodity, but by government decree (e.g., USD, NGN, KES). 

Immutability: This means that once a transaction is recorded in a block, it cannot be altered or deleted later.

Issuer: ​​This refers to the centralized entity or organization responsible for managing the reserves, minting, and burning of a stablecoin (e.g., Circle for USDC).

Blockchain Transaction: The immutable, cryptographically signed record of an action (sending, receiving, etc.) submitted to the blockchain.

Blockchain Explorer: A public tool used to track wallet balances, transactions, and block confirmations on a specific blockchain network.

Wallet Address: A wallet address is the unique, publicly shareable identifier (a hashed and encoded Public Key) used to receive funds. Think of it like an “account number” in the fiat world.

USDC: USDC is a stablecoin issued by the Circle network designed to have the same value as the United States dollar.

USDT: USDT is a stablecoin issued by Tether Limited and pegged at 1:1 to the United States dollar. 

Gas Fees: A small fee paid to the blockchain network to execute a transaction and compensate the validators/miners for their computational work. 

Transaction Hash: A unique string of alphanumeric characters that identifies a specific transaction on the blockchain (a transaction ID).

Peg/Pegging: The mechanism by which a stablecoin maintains its target value (e.g., 1 USDC is approximately 1 USD).

De-peg: An event where a stablecoin fails to maintain its intended 1:1 ratio with its pegged asset (e.g., USDC trading at $0.98 instead of $1).

Reserves: The real-world assets (fiat, short-term treasury bills, etc.) that a stablecoin issuer holds in reserve to back the stablecoin's value.

Volatility: This is a measure of how rapidly and dramatically the price of an asset can change. Stablecoins are designed to have low volatility.

Wallet Network: Wallet network or network is the specific blockchain infrastructure used to move and store your digital assets.

Onramp: This is the process of converting traditional fiat currency into cryptocurrency or stablecoin. 

Offramp: This is the process of converting cryptocurrency or stablecoin into traditional fiat currency.

Congestion: Network congestion occurs when the number of transactions waiting to be processed at a given time exceeds the network processing capacity. Network congestion could lead to increased transaction fees and delayed transaction confirmation. 

Liquidity: This is the degree to which an asset can be quickly bought or sold in the market without affecting the asset's price. 

Liquidity Pool: A collection of cryptocurrency locked in a smart contract that facilitates decentralized trading and lending on a DEX.
