Bitcoin's whitepaper appeared on Halloween 2008 from a still-unidentified "Satoshi Nakamoto" — and 16 years later, the network has secured over $2 trillion in value. From the genesis block in January 2009 to spot Bitcoin ETFs in 2024, the rise of Ethereum smart contracts, NFT mania, DeFi summer, and the spectacular FTX implosion, blockchain has rewritten finance, art, and the internet itself.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll dig into the Bitcoin halving schedule, Ethereum's Merge to proof-of-stake, the NFT booms and busts (Beeple's $69M sale, Bored Ape Yacht Club), DeFi protocols like Uniswap and Aave, and the FTX collapse that took down Sam Bankman-Fried — plus stablecoins, Layer 2 rollups, infamous hacks, and the DAOs trying to buy the Constitution.
Bitcoin was created by a pseudonymous person or group known as Satoshi Nakamoto, who published the whitepaper "Bitcoin: A Peer-to-Peer Electronic Cash System" on October 31, 2008 and mined the genesis block on January 3, 2009. Their real identity remains unknown.
A smart contract is self-executing code stored on a blockchain that runs automatically when predefined conditions are met. Ethereum, launched in 2015 by Vitalik Buterin, popularized smart contracts via the Ethereum Virtual Machine (EVM) and the Solidity programming language.
The Merge was Ethereum's transition from proof-of-work to proof-of-stake on September 15, 2022. It cut the network's energy consumption by roughly 99.95% and replaced miners with validators who must stake at least 32 ETH.
