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.

If you are new to the space, I would recommend you to learn as much as you can and sometimes things may not make sense at first but trust me they will. Learn Blockchain basics from my article here.

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

If more than half the computer power or mining hash rate on a network is run by a single person or a single group of people, then a 51% attack is in operation.

🔹 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. 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.

🔹 Blockchain 3.0

Blockchain 3.0 is the final developmental stage of blockchain technology, which predicts global, institutional and enterprise adoption.

🔹 Stablecoin

A cryptocurrency with extremely low volatility is sometimes used as a means of portfolio diversification. Examples include gold-backed cryptocurrency or fiat-pegged cryptocurrency.

🔹 HODL

A type of passive investment strategy where you hold an investment for a long period of time, regardless of any changes in the price or markets.

The term first became famous due to a typo made in a Bitcoin forum, and the term is now commonly expanded to stand for “Hold On for Dear Life.”

🔹 Buy The (F******* ) Dip (BTD/BTFD)

An enthusiastic exclamation by supporters of a cryptocurrency to buy while prices are at a low point.

🔹 Smart Contract

A smart contract is a computer protocol intended to facilitate, verify or enforce a contract on the blockchain without third parties.

🔹 Layer 2

Layer 2 is the name given to a scaling solution that enables high throughput of transactions whilst fully inheriting the security of the underlying blockchain that it is built on.

🔹 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.

🔹 DAO

A DAO, or “Decentralized Autonomous Organization,” is a community-led entity with no central authority. 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

🔹 Centralized Exchange (CEX )

Centralized exchanges (CEXs) are a type of cryptocurrency exchange that is operated by a company that owns it in a centralized manner ie Coinbase

🔹 Mainnet

An independent blockchain running its own network with its own technology and protocol.

🔹 DeFi

Decentralized finance (Defi) offers financial instruments without relying on intermediaries such as brokerages, exchanges, or banks.

🔹 Liquidity Mining

Liquidity mining is a mechanism or process in which participants supply cryptocurrencies into liquidity pools, and are rewarded with fees and tokens based on their share of the total pool liquidity.

🔹 Dumping

A collective market sell-off occurs when large quantities of a particular cryptocurrency are sold in a short period of time.

🔹 Tokens

Tokens are a type of cryptocurrency that are used as a specific asset or represent a particular use on the blockchain.

They are sometimes created through initial coin offerings (ICOs) — or other fundraising methods including initial DEX offerings (IDOs).

🔹 Dusting Attack

An attack that aims to uncover the identity of a wallet’s owner, information that can subsequently be used in phishing scams.

🔹 ERC-20

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.

Every Ethereum node runs on the EVM to maintain consensus across the blockchain.

🔹 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.

🔹 Hard Fork

A type of protocol change that validates all previously invalid transactions, and invalidates all previously valid transactions.

🔹 Metaverse

It is a network of 3D virtual worlds where people avatars can interact with digital objects and with other people.

🔹 Cryptocurrency (crypto )

A decentralized digital currency, created using cryptographic techniques. Crypto is decentralized, which means, it is independent of a monetary authority like banks and government.

Everyone can issue the cryptocurrency (mine), buy, sell or trade without limits and control. Transactions are secure and much faster than traditional currency.

A crypto wallet is a place where you can securely keep your crypto. There are many different types of crypto wallets with both hardware and software mainly used.

🔹 Miner

Nodes in the blockchain. Each of the miners is guessing a 64-digit hexadecimal number, a token, that is generated during the transaction (inserting a new record into the blockchain).

🔹 NFT

Nonfungible token — is a unique token stored in a blockchain that represents digital assets, like music, image, art, 3d models. Nonfungible means unique and non-interchangeable.

🔹 Ethereum

An open-source software platform that works in the public blockchain networks and focuses on running DApps applications.

It also has its own cryptocurrency for making payments inside the network, called Ether.

🔹 Solidity

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. A blockchain that solves the major problems of scalability, transaction speed, price, energy efficiency. It is open-source that encourages to develop the DApps.
