Blockchain
A type of distributed ledger that holds transaction data in "blocks" which are cryptographically linked and secured.
Bitcoin
The first successful implementation of a digital currency using blockchain technology, invented by an anonymous person or group of people under the pseudonym Satoshi Nakamoto.
Ethereum
A blockchain-based platform that supports smart contracts, enabling more complex financial and logistical operations beyond simple transactions.
Stellar
Stellar makes it possible to create, send, and trade digital representations of all forms of money: dollars, pesos, bitcoin, pretty much anything. It’s designed so all the world’s financial systems can work together on a single network.
Smart Contract
A self-executing contract with the terms of the agreement directly written into code. They automatically enforce and execute when conditions in the contract are met.
Decentralized Application (DApp)
Applications that run on a decentralized network, rather than being controlled by a single authority or organization.
Decentralized Finance (DeFi)
A sector of blockchain-based applications designed to eliminate traditional financial intermediaries, offering services like lending, borrowing, and trading.
Web3
Short for "Web 3.0", this term represents the next generation of the internet, one where decentralized blockchain technologies and cryptocurrencies play a vital role.
NFT
NFT stands for "Non-Fungible Token." It is a type of cryptographic token on a blockchain that represents a unique item or piece of content. Unlike cryptocurrencies like Bitcoin or Ethereum which are fungible and can be exchanged on a one-for-one basis, NFTs are unique and can't be exchanged like-for-like.
Cryptocurrency
A type of digital or virtual currency that uses cryptography for security. Bitcoin, Ethereum, and Litecoin are examples.
NFT (Non-fungible token)
A type of digital asset that represents ownership or proof of authenticity of a unique item or piece of content, using blockchain technology.
Mining
The process of validating and adding new transactions to a blockchain's ledger, often requiring significant computational power.
Wallet
A digital tool that allows users to interact with a blockchain network. Wallets can hold cryptographic keys that allow a user to send and receive cryptocurrencies.
Gas (in Ethereum)
The fee required to perform a transaction or execute a contract on the Ethereum network.
DAO (Decentralized Autonomous Organization)
An organization represented by rules encoded as a computer program that is transparent, controlled by the organization members and not influenced by a central government.
Proof of Work (PoW)
A consensus algorithm used in blockchain networks where miners compete to solve a complex mathematical problem first. It is used to validate transactions and produce new blocks to the chain.
Proof of Stake (PoS)
An alternative to PoW, where validators are chosen to create a new block based on the amount of cryptocurrency they hold and are willing to "stake" as collateral.
Layer 2
Secondary frameworks or protocols built on top of an existing blockchain network to improve its scalability and efficiency.
Stablecoin
A type of cryptocurrency that is designed to maintain a stable value by being pegged to a reserve of assets, often a specific amount of fiat currency like the US dollar.
Token
A digital representation of a particular asset or utility that resides on top of another blockchain. Tokens can represent any assets that are fungible and tradable.
Interoperability
The ability for different blockchain networks to communicate and interact with each other.
Sharding
A scalability solution that involves dividing a blockchain into several smaller, more manageable pieces, or "shards," each capable of processing its own transactions and smart contracts.
Lumens (XLM)
The native cryptocurrency of the Stellar network. Lumens serve as a bridge currency for transactions involving different currencies and are used to pay for transaction fees on the network.
Stellar Consensus Protocol (SCP)
The consensus algorithm used by the Stellar network. It provides a way to reach consensus without relying on a closed system to accurately record financial transactions.
Federated Byzantine Agreement (FBA)
The model of consensus employed by the SCP, which requires nodes to only trust a subset of the overall network. This model strikes a balance between decentralization and efficiency.
Stellar Development Foundation (SDF)
The organization responsible for maintaining and overseeing the development of the Stellar network.
Anchors
Entities within the Stellar network that issue assets and take deposits. They serve as a bridge between existing financial systems and the Stellar network.
Stellar Core
The software that nodes on the Stellar network run to validate transactions and reach consensus.
Path Payment
A feature of the Stellar network that allows a user to send one type of asset while the receiver gets another type of asset. Stellar automatically converts the asset at the most favorable rate.
Stellar Toml
A TOML file that Stellar service providers host to allow clients to discover information about their organization. It includes information such as the organization's currency documentation, images, brand color, etc.
Multi-Signature
A security feature that requires multiple parties to sign a transaction before it can be executed. Stellar supports multi-signature transactions, enhancing the security of the network.
Node
A node is a fundamental unit in a network or data structure, representing a point of connection or an element in a graph. In computing, it often refers to an individual element in a linked data structure or a computing device within a network.
