Blockchain

A decentralized, distributed ledger that records transactions across many computers. It's made up of blocks linked together chronologically and secured using cryptography.

NFT

A unique digital asset that represents ownership of a specific item or piece of content. Unlike cryptocurrencies, NFTs are not interchangeable.

Minted NFT

Minting an NFT refers to the process of writing a digital item to the blockchain. This establishes its immutable record of authenticity and ownership. This process usually involves things like assigning metadata to the NFT, which can include information about the creator, a description of the content, and other relevant details. Minting establishes ownership and provenance of the digital item on the blockchain, ensuring its uniqueness and authenticity.Both creators and collectors can mint NFTs. For both creators and collectors, minting NFTs establishes verified ownership and ownership history. For creators, minting their own NFTs gives them ownership and control of their own work, and allows them to build special communities and perks for those who hold their NFTs. When either the creator or a collector mints an NFT from a project, they become the first-ever owner of that NFT, since the NFT is written onto the blockchain during the mint.

BlockBlock:

A batch of verified transactions that are bundled together and added to the blockchain. Each block contains a timestamp and a link to the previous block.

Node

A computer connected to the blockchain network that helps to validate and relay transactions.

Decentralization

The distribution of control and decision-making away from a central authority to a distributed network of participants.

Cryptocurrency

A digital or virtual form of money that uses cryptography for security. Many cryptocurrencies operate on a blockchain.

Transaction

An exchange of value recorded on the blockchain

Mining –

The process by which new transactions are verified and added to the blockchain, often involving solving complex computational problems (Proof-of-Work).

Proof-of-Stake (PoS)

A consensus mechanism where validators are chosen to create new blocks based on the amount of cryptocurrency they "stake" or hold.

Smart Contract

Self-executing contracts with the terms of the agreement directly written into code. They automatically execute when predefined conditions are met.

Wallet
A digital tool used to store, send, and receive cryptocurrencies and interact with blockchain applications.

Public Key
A cryptographic address that can be shared with others to receive cryptocurrency.

Private Key
A secret key that allows the owner to access and spend their cryptocurrency. It should be kept secure.

Hash
A unique, fixed-size code generated from a block of data. Hashes are used to link blocks together and ensure data integrity.

Ledger
A record of transactions. In the context of blockchain, it's a digital and distributed record.

Consensus Mechanism

The method by which all participants in a blockchain network agree on the validity of transactions and the state of the ledger (e.g., Proof-of-Work, Proof-of-Stake).

Gas
A fee required to perform transactions or execute smart contracts on some blockchain networks, like Ethereum.

Token
A digital asset that can represent various things, such as utility within a platform or ownership of an asset.

dApp (Decentralized Application)
An application that runs on a decentralized network like a blockchain, rather than a centralized server.

Web3

The concept of a new iteration of the internet that is decentralized and built on blockchain technology.

Did You Know? (Blockchain Edition)

Q: Did you know blockchain was originally created for Bitcoin?
A: Yes! Blockchain was introduced in 2008 by Satoshi Nakamoto as the underlying tech for Bitcoin.
Q: Did you know blockchain is not just for cryptocurrency?
A: Correct. It’s used in supply chains, voting systems, healthcare, real estate, and more.
Q: Did you know a blockchain is a type of distributed ledger?
A: Yes, it records transactions across a network of computers.
Q: Did you know blockchain data is immutable?
A: Once a block is added, it cannot be changed without altering the entire chain.
Q: Did you know Ethereum introduced smart contracts?
A: True. Ethereum allowed developers to automate agreements through code.
Q: Did you know a "block" contains more than just transactions?
A: It also includes a timestamp, a nonce, and a reference to the previous block.
Q: Did you know "mining" is how new blocks are added to some blockchains?
A: Yes, miners solve complex puzzles to validate transactions and earn rewards.
Q: Did you know blockchain can prevent fraud in supply chains?
A: Yes, it offers transparency and traceability from production to delivery.
Q: Did you know NFTs use blockchain to prove ownership of digital art?
A: Exactly. NFTs are unique tokens tied to digital assets on a blockchain.
Q: Did you know blockchain is nearly impossible to hack?
A: True. It would require controlling over 50% of the network’s nodes—extremely difficult.
Q: Did you know blockchain technology supports decentralized finance (DeFi)?
A: DeFi lets people lend, borrow, and trade assets without banks.
Q: Did you know blockchain uses cryptography to secure data?
A: Yes, data is encrypted and linked using hash functions.
