If you’re new to crypto, or need a refresher on some key concept, this page is for you!

Here, you will find articles that will teach you about terms that you may come across in your everyday life if you are plugged into crypto Twitter, crypto news, or others. Do you want to learn about how blocks work in a blockchain? What is a block size or block time? Maybe you are curious about the difference between proof of work and proof of stake.

You can also navigate to our stablecoins article and learn how they are programmed to maintain a value approximately equal to another asset. You can also learn about how decentralized autonomous organizations (DAOs) are community-based entities with a democratized governance structure based on blockchain technology.

Crypto coins vs tokens
Crypto coins vs tokens
Coins and tokens are often misunderstood and thought to be the exact same thing. This may be partly because terminology in the crypto universe is not always as straightforward as would be desired. And while they are both units of cryptocurrency, coins and tokens do have different functionalities. At least to some extent.
Exploring Bitcoin’s forks
Exploring Bitcoin’s forks
Since the release of Bitcoin in 2009, the Bitcoin community has had many different ideas on improving the Bitcoin blockchain. A lot of these improvements were not compatible with one another and ended up creating something called hard forks.
How do cryptocurrency transactions work?
How do cryptocurrency transactions work?
To transfer cryptocurrencies like bitcoin, a fundamentally different infrastructure is needed from traditional payment systems. The Bitcoin network is the first infrastructure to enable peer-to-peer transfers of digital money, putting the advantages of blockchain technology and public-key cryptography into practice.
How do smart contracts work?
How do smart contracts work?
Smart contracts are pieces of code stored within a blockchain that specify a number of conditions and can only be executed once these conditions are met. They come in many different shapes and sizes, from those that move around coins or tokens within the blockchain environment, to those that rely on external data to satisfy their conditions.
What are Bitcoin blockchain nodes?
What are Bitcoin blockchain nodes?
A blockchain node is one of numerous devices that run the blockchain protocol software and usually store the history of transactions. Nodes connect to each other in a decentralized peer-to-peer network.
What are blockchain forks?
What are blockchain forks?
In the context of blockchain, a fork is a technical phenomenon that occurs when a blockchain splits into two separate branches. These two branches share their transaction history up until the point of the split. From there on, they each go independently each in their own direction.
What are decentralized applications? (dapps)
What are decentralized applications? (dapps)
A decentralized application (dapp for short) is an application coded into a blockchain.
What are decentralized autonomous organizations? (DAO)
What are decentralized autonomous organizations? (DAO)
A decentralized autonomous organization, or DAO, is a community-based entity with a democratized governance structure based on blockchain technology.
What are NFTs? (Non-Fungible Tokens)
What are NFTs? (Non-Fungible Tokens)
Non-fungible tokens, or NFTs, are digital representations of anything that is unique. They can represent various sorts of digital assets or even physical items, like cars or art. These non-fungible tokens are most often implemented on the Ethereum blockchain.
What are smart contracts?
What are smart contracts?
The Ethereum blockchain exists on computers all across the world. Besides being the ledger for its own cryptocurrency, ether, one of the greatest perks of the Ethereum platform is its ability to run smart contracts.
What are stablecoins?
What are stablecoins?
Stablecoins are cryptocurrencies that are programmed to maintain a value approximately equal to another asset.
What are the blocks in blockchain?
What are the blocks in blockchain?
A blockchain is exactly what it sounds like it is: a chain consisting of blocks of information. These blocks are containers holding a record transactions on the blockchain. In the case of Bitcoin, the transactions are primarily transfers of bitcoins. On some blockchains, they can also contain a variety of other information, even code of computer programs.
What is a satoshi?
What is a satoshi?
Traditional currencies, like USD, can be divided into smaller units – like cents. Cryptocurrencies also have these divisions and smaller units. In the case of bitcoin, the smallest unit available is called a satoshi.
What is an Initial Coin Offering? (ICO)
What is an Initial Coin Offering? (ICO)
An Initial Coin Offering (ICO) is a popular way of raising funds for cryptocurrency-related startups. An ICO is the first time a new cryptocurrency is offered for sale. It is the equivalent of a stock’s IPO (initial public offering).
What is block size?
What is block size?
The size of a block equals the amount of data it stores. And just like any other container, a block can only hold so much information. The largest amount of data a blockchain block can hold is referred to as the block size limit.
What is block time?
What is block time?
In blockchain technology, a transaction is never instant. It can only take place once a block containing the transaction data has been generated. The time needed to create this new block is called block time.
What is blockchain mining?
What is blockchain mining?
In the cryptocurrency industry, mining means adding new blocks of data to a blockchain. Cryptocurrency miners have to find a solution to a complex mathematical problem before they can create a new block. They are then rewarded with newly-created coins of cryptocurrency.
What is ERC-20?
What is ERC-20?
Ethereum is a blockchain system that enables the creation and transfers of various kinds of tokens. These tokens have many uses and include those which are fungible, non-fungible tokens, or have other characteristics - and there are a variety of different token standards for each. Today we will present the most popular token standard for Ethereum, the ERC-20.

Perhaps you’ve heard about non-fungible tokens (NFTs) - unique digital assets representing a piece of media (like art, music, gaming, or membership badges) that exist on the blockchain.
