Blockchain: A blockchain is a digital ledger that stores all the transactions in a decentralized and secure way thanks to cryptographic mechanisms**.** Instead of relying on third parties such as banks to serve as the middleman in a transaction, you can securely send money without having to trust the recipient by doing it on a Blockchain. Every action taken on the Blockchain must be verified by others to be approved, making sure there is no fraud.

Crypto Wallet: The same way you have banking information that you share with anyone that wants to send you money, a crypto wallet creates and stores your Private & Public Keys (a series of numbers similar to your banking information) that allows you to send and receive money on the Blockchain. You’ll use your Public Key as Banking information, while your Private Key will serve to verify and validate the transactions. A Crypto Wallet is from where you’ll be able to send/request cryptocurrencies and see how much crypto you have.

Decentralized Autonomous Organizations (DAO): DAOs have emerged in recent years, allowing people to collaborate on smaller-scale projects than companies. DAOs are organized around a mission that coordinates through a shared set of rules enforced on a blockchain. Put it simply, DAOs are a new way to finance projects, govern communities, and share value.

Gas fees: Gas Fee is a term used to describe the transaction fee taken by the Ethereum blockchain upon the execution of a smart contract. Every transaction happening on the Ethereum Blockchain needs to be verified by others to be approved. Users that verify the transactions are called “Miners” and to thank those contributors (Miners) for verifying a transaction and incentivizing them to make the network more secure, we give them a tip, a slice of the trade, also called “Gas fees.” You can find the price of the Gas fees on EtherScan. The fractional denomination of Ether used when referring to gas prices is “Gwei.” A reasonably “good price” can range between 20 to 30 Gwei. Gas fees are often exceeding these numbers.

Non-fungible token (NFT): Non-fungible token (NFT) is a term used to describe a unique digital asset whose ownership is tracked on a blockchain, such as Ethereum. Assets that can be represented as NFTs range from digital goods, such as items that exist within virtual worlds, to claims on physical assets such as clothing items or real estate.

Social Token: A social token is a digital currency that lives in a virtual economy. Anyone can create their own Social Token and incentivize people to work in exchange for this Token. Social Tokens, finally, make it easier to collaborate on smaller-scale projects and help create trust between parties. Instead of setting up contracts and legal status to cover each contributor, Social Tokens allow doing transactions on a blockchain, meaning enforced by crypto mechanisms, in a trustful way.

Web3: The terms “Web3” or “Decentralized Web” are slowly taking over “crypto.” Web3 is a broader term that comes without the 2017 baggage of the word “Crypto.” Indeed, “Crypto” is too often associated with “scam” and “speculation.” Instead, the term “Web3” is more reminiscent of the evolution of the internet as we know it today, solving the most pressing problems of Web2 platforms through Crypto mechanisms.
