Hey fellow techie👋, let's get into the web 3.0 jargon today to understand what exactly is happening behind building the worlds' new web of decentralisation and permissionless.

When I was new to the community, I would hear or come across a new term almost every other day.

So here are the 45 most used terms in web 3 space in no particular order: 🚀🚀

🔹 Algo-Trading (Algorithmic Trading)

Algo-trading is an automated trading system where buy and sell orders are placed according to the rules of a computer program or algorithm.

🔹 InterPlanetary File System (IPFS)

The InterPlatery File System is a peer-to-peer, distributed system for storing and accessing files, as well as websites and applications, which relies on content addressing rather than location.

🔹 51% Attack

🔹 Airdrop

An "airdrop" refers to a method of distributing cryptocurrency to the public, via the fact that they own certain other tokens or wallets on a particular blockchain.

🔹 Block Size

In blockchain technology, block size refers to the amount of data about transactions a single block in the chain can carry.

🔹 Lambo

Lambo is shorthand for Lamborghini, an exotic car that people often refer to in their excitement over getting rich from cryptocurrencies. image.png It is basically a slang for the type of car that many crypto enthusiasts aspire to buy when their digital assets “moon” — or rise in value substantially.

🔹 Smart Contract

🔹 GM

The acronym “GM” typically stands for “Good Morning.” GM Wagmi is a project that takes inspiration from this greeting, having created a whole new token to spread positivity and make the crypto space a better place.

🔹 Consensus

A set of rules in a blockchain system has to be verified in order to achieve the agreement on a single data value or a single state of the network.

🔹 Proof-of-Work (PoW)

A blockchain consensus mechanism involving solving computationally intensive puzzles to validate transactions and create new blocks.

🔹 Byzantine Fault Tolerance (BFT)

Byzantine Fault Tolerance (BFT) is the property of a computer system that allows it to reach consensus regardless of the failure of some of its components.


🔹 Off-Chain

A transaction that is processed outside the blockchain network with an increased speed and reduced cost.

🔹 Minting

Minting is the process of generating new coins using the proof-of-stake mechanism and adding them to the circulation to be traded.

🔹 Cold Storage

Offline storage of cryptocurrencies, typically involving hardware non-custodial wallets, USBs, offline computers, or paper wallets.


A DAO, or “Decentralized Autonomous Organization,” is a community-led entity with no central authority. image.png It is fully autonomous and transparent: smart contracts lay the foundational rules, execute the agreed-upon decisions, and at any point, proposals, voting, and even the very code itself can be publicly audited.

🔹 Dead Cat Bounce

A temporary recovery in prices after a prolonged decrease.

🔹 Testnet

As the name suggests, a testnet is a separate blockchain where developers can put new features through their paces without worrying about jeopardizing the main network.

🔹 dApps

Dapps are decentralized applications that live on the blockchain. ... Several platforms are available to deploy dApps on, including Ethereum, Polygon, Solana, Avalanche, etc.

🔹 MetaMask

An online digital wallet that allows users to manage, transfer and receive Ethereum, operating as an extension to a regular browser.

🔹 Decentralized Exchange (DEX )

A peer-to-peer exchange that allows users to trade cryptocurrency without the need for an intermediary IE Uniswap

ERC-20 tokens are based on the Ethereum blockchain. Just like mainstream cryptocurrencies such as Bitcoin, they can be used to make purchases — or traded for fiat currencies and crypto.

🔹 Ethereum Virtual Machine (EVM)

A Turing-complete virtual machine that enables execution of code exactly as intended; it is the runtime environment for every smart contract.

🔹 Faucet

A cryptocurrency reward system usually on a website or app, rewards users for completing certain tasks.

🔹 Gas

A term used on the Ethereum platform refers to a unit measuring the computational effort of conducting transactions or smart contracts or launching DApps in the Ethereum network. It is the “fuel” of the Ethereum network. *see Gas Limit and Gas Price.

A programming language for writing smart contracts in blockchain, such as Ethereum. The program has to be compiled in Ethereum Virtual Machine.

🔹 Solana

Solana is a public blockchain platform. Its native cryptocurrency is SOL. image.png A blockchain that solves the major problems of scalability, transaction speed, price, energy efficiency. It is open-source that encourages to develop the DApps.
