Example: Token holders can lock their tokens in a smart contract to participate in a staking program.

Token Metrics: Characteristics and data related to a cryptocurrency token, such as supply, distribution, and use cases.

Example: Token metrics help investors assess a token’s potential value and utility in the market.

Token Migration: The process of moving a cryptocurrency token from one Blockchain to another.

Example: A token migration may occur when a project moves its token from an older Blockchain to a more advanced Blockchain with improved features.

Token Minting: The process of creating new tokens on a Blockchain network.

Example: Tokens can be minted and distributed to users as rewards for contributing to a decentralized application.

Token Pegging: Tying the value of a cryptocurrency token to that of a fiat currency or another asset.

Example: A stablecoin can be pegged to the value of the US dollar to maintain price stability.

Token Recycling: The practice of repurchasing or reusing tokens to support the ecosystem or reduce supply.

Example: A project may recycle a portion of its revenue to buy back and burn its native tokens.

Token Standard (e.g., ERC-20, ERC-721): Protocols that define the rules and standards for creating and interacting with tokens on a Blockchain network.

Example: ERC-20 is a widely used standard for creating fungible tokens, while ERC-721 is used for non-fungible tokens.

Token Swaps: Exchanging one cryptocurrency token for another directly on a Blockchain network.

Example: A decentralized exchange allows users to perform token swaps without the need for a central intermediary.

Token Unlocking: The release of locked or vested tokens after a specific period or milestone.

Example: A project’s team members may have their tokens unlocked gradually over several years to incentivize long-term commitment.

Token Vesting: The gradual release of tokens over a specified period to ensure responsible and measured distribution.

Example: Token vesting prevents early investors and team members from selling all their tokens at once.

Token Whitelisting: A process where users must be pre-approved to participate in a token sale or other events.

Example: To prevent bot activity, a project may require users to be whitelisted before participating in its token sale.

Tokenomics: The economic design and study of how cryptocurrency tokens function within an ecosystem.

Example: Tokenomics considers token distribution, inflation, utility, and overall supply-demand dynamics.

Treasury DAO: A decentralized autonomous organization that manages and governs a project’s financial resources.

Example: A treasury DAO makes decisions on fund allocation for development, marketing, and other expenses.


Validator: A participant in a proof-of-stake or delegated proof-of-stake network responsible for validating transactions and adding blocks.

Example: In the Cardano network, validators stake their ADA tokens and are selected to create new blocks based on their stake.

Virtual Reality (VR) Metaverses: Virtual worlds or environments created using VR technology, often connected through Blockchain networks.

Example: VR metaverses allow users to interact, socialize, and conduct business in a shared digital space.


Web3: The vision of a more decentralized and user-centric internet built on Blockchain and decentralized technologies.

Example: Web3 aims to empower users with more control over their data and digital interactions.

Web3 Browser: A web browser that natively supports decentralized applications and Blockchain networks.

Example: Brave is a web3 browser that integrates a cryptocurrency wallet for seamless DeFi interactions.

Web3 Development Frameworks: Tools and libraries that aid developers in creating decentralized applications.

Example: Truffle and Hardhat are popular web3 development frameworks for building smart contracts.

Web3 Education Platforms: Online platforms that offer educational resources and courses on Blockchain and web3 technologies.

Example: Coursera and Udemy offer web3 development courses for aspiring Blockchain developers.

Web3 Foundation: An organization that supports the development and growth of the web3 ecosystem.

Example: The Web3 Foundation funds various projects and research initiatives in the decentralized technology space.

Web3 Funding Models: Different methods of funding web3 projects, including ICOs, grants, and venture capital.

Example: Some projects raise funds through token sales, while others receive grants from foundations.

Web3 Identity: Identity systems that provide users with control and ownership over their digital identities.

Example: Web3 identity solutions use decentralized identifiers (DIDs) and Blockchain-based attestations.

Web3 Wallet: A cryptocurrency wallet designed for web3 applications and interactions.

Example: MetaMask is a popular web3 wallet that allows users to access and interact with decentralized applications.

Wrapped BTC (WBTC): A tokenized version of Bitcoin that can be used on Blockchain networks that support ERC-20 tokens.

Example: WBTC allows users to bring Bitcoin liquidity to the Ethereum DeFi ecosystem.

Wrapped Token: A tokenized version of an asset from one Blockchain network, compatible with another network’s standards.

Example: Wrapped ETH (WETH) represents ETH on the Ethereum network, making it compatible with ERC-20 standards.

Yield Aggregator: A platform or protocol that automatically seeks the highest yield opportunities for users’ funds.

Example: Yearn Finance is a yield aggregator that optimizes yield farming strategies for its users.

Yield Farming: A DeFi practice where users provide liquidity to earn rewards in the form of additional tokens.

Example: Users can engage in yield farming by staking their tokens in liquidity pools.

Yield Optimization: Strategies employed to maximize yield and returns on cryptocurrency assets.

Example: DeFi users use yield optimization techniques to earn the highest rewards from their assets.


Zero-Knowledge Proof (ZKP): A cryptographic method that proves the truth of a statement without revealing any specific information about it.

Example: ZKPs enable users to prove ownership of a private key without disclosing the actual key.

zk-Rollups: A Layer 2 scaling solution that aggregates multiple transactions off-chain and submits a single proof to the main Blockchain.

Example: zk-Rollups can significantly reduce transaction fees and increase throughput on Ethereum.

zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge): A type of ZKP that enables efficient and compact proofs.

Example: Zcash uses zk-SNARKs to ensure transaction privacy and confidentiality.

zk-STARKs (Zero-Knowledge Scalable Transparent ARguments of Knowledge): A more recent and efficient form of ZKP.

Example: zk-STARKs can be used to provide trustless verification without revealing sensitive data.
