Bitcoin, Ethereum, and blockchain — how well do you understand the crypto revolution?
Bitcoin, Ethereum, and blockchain — how well do you understand the crypto revolution?
On May 22, 2010, a programmer named Laszlo Hanyecz paid 10,000 Bitcoin for two Papa John's pizzas — the first real-world Bitcoin purchase ever recorded. Those coins would later be worth hundreds of millions of dollars. From that humble transaction to a multi-trillion-dollar market, cryptocurrency has reshaped how the world thinks about money. This quiz covers Bitcoin, Ethereum, blockchain technology, DeFi, NFTs, wallets, regulation, and plenty of surprising crypto trivia.
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 discover who Satoshi Nakamoto is, how blockchain consensus mechanisms work, what makes Ethereum different from Bitcoin, how DeFi protocols and NFTs function, the history of major crypto crashes and rallies, how wallets and private keys keep your funds secure, which countries have embraced or banned cryptocurrency, and some of the wildest projects the crypto world has ever seen.
Bitcoin is a decentralized digital currency that operates on a peer-to-peer network without a central authority. Transactions are verified by miners who solve complex mathematical puzzles (proof of work) and are recorded on a public ledger called the blockchain. New bitcoins are created as mining rewards, with the total supply capped at 21 million coins.
Bitcoin was designed primarily as a digital currency and store of value, while Ethereum is a programmable blockchain platform that supports smart contracts and decentralized applications (dApps). Ethereum's native currency is Ether (ETH). Bitcoin uses proof of work for consensus, while Ethereum transitioned to proof of stake in 2022 with "The Merge," significantly reducing its energy consumption.
Cryptocurrency is a highly volatile and speculative asset class. While major coins like Bitcoin and Ethereum have seen enormous long-term growth, they have also experienced crashes of 50% or more. Risks include exchange hacks, scam projects, regulatory uncertainty, and the irreversibility of transactions. Experts recommend only investing what you can afford to lose and using secure wallets to protect your holdings.
