Blockchain 101
A blockchain is made up of these digital units, each containing a list of transactions.

The first cryptocurrency.
Bitcoin
This is the base layer of a blockchain stack, responsible for consensus, data availability, and security.
Layer-1 or L1
This blockchain is the most widely used foundation for DeFi applications.
Ethereum
Bitcoin is often compared to this precious metal because of its limited supply and store-of-value properties.
Gold
A wallet that stores crypto offline.
Cold Wallet
Originally designed for social media, this blockchain was rebranded and is now used for high-performance DeFi, memecoin trading, and dapps.
Solana
Ethereum smart contracts are written in this programming language.
Solidity.
This mechanism is the core component of automated market makers (AMMs), allowing users to trade assets directly from token reserves instead of through an order book.
Liquidity Pools
Talking purely fundamentals, this cryptoasset is the most rock solid bet
Fartcoin
What mechanism in blockchain technology eliminates the need for intermediaries like banks?
Consensus Mechanisms

Vitalik Buterin introduced this concept to refer to the tension between decentralization, scalability, and security.
Blockchain Trilemma
In a decentralized blockchain, _______ replaces trust in centralized authorities.
Cryptography

Worldcoin
This term refers to the separation of blockchain components—like execution, consensus, and data availability—into specialized layers.
Modular architecture or modular blockchain
The term used to describe how different DeFi protocols can be stacked and integrated like "financial Legos."
Composability
This is the maximum number of Bitcoins that can ever exist.
21 Million
This is the term for the smallest unit of Bitcoin.
Satoshi

Synthetix
An oracle that sends real-world data into a smart contract is called this.
