Memorize Crypto and DeFi Fundamentals: 80 Flashcards from Proof of Work to Impermanent Loss
Learn crypto and DeFi with 80 flashcards: proof of work vs stake, mining, wallets, AMMs, liquidity pools, flash loans, tokenomics, DAOs and the risks of DeFi.
Most people who quit crypto do not quit the technology — they quit the vocabulary: halving, hash rate, a wallet that stores no coins. Deck YK8316 — Blockchain & Cryptocurrency Fundamentals (72 cards) on Flip It is built to clear exactly that barrier: definitions short enough to recall in one breath, covering the whole stack from cryptographic primitives to the 2022 blow-ups.

What the 72 cards actually cover
The deck runs in loose blocks. Core mechanics: blockchain, block, distributed ledger, decentralization, consensus mechanism, Byzantine Fault Tolerance, immutability, transparency, genesis block, fork / hard fork / soft fork. Cryptography and mining: hash, hash rate, SHA-256, public-key cryptography, private vs public key, proof-of-work, proof-of-stake, mining pool, ASIC miner, GPU mining, double-spending, 51% attack, zero-knowledge proofs. Holding coins: hot, cold, paper and hardware wallets, nodes, blockchain explorers, exchanges, Bitcoin ATMs, satoshi, wei. Assets: Bitcoin, Ethereum, Litecoin, Monero, Dogecoin, Namecoin, Peercoin, altcoins, stablecoins, memecoins, NFTs. Applications and money: smart contracts, gas, DeFi, DApps, DAOs, staking, yield farming, ICOs, atomic swaps, transaction fees. Market reality: volatility, HODL, FUD, FOMO, the Terra/Luna collapse, the FTX bankruptcy, scalability and the blockchain trilemma.
Ten cards worth memorizing first
| Front | Back |
|---|---|
| Block in blockchain | A record containing a hash pointer to the previous block, a timestamp, and transaction data |
| Proof-of-work (PoW) | A consensus mechanism requiring miners to solve complex computational problems to validate transactions |
| Proof-of-stake (PoS) | Validators are chosen based on the amount of cryptocurrency they hold and stake |
| What hash function does Bitcoin use? | SHA-256 (Secure Hash Algorithm 256-bit) |
| Bitcoin halving | An event occurring roughly every 4 years where mining rewards are cut in half, controlling supply |
| Maximum supply of Bitcoin | 21 million bitcoins — a hard cap defined in the protocol |
| Smart contract | Self-executing contracts with terms written directly in code that run on a blockchain |
| Gas in Ethereum | A unit measuring computational effort required to execute operations; users pay gas fees |
| 51% attack | When a single entity controls more than half of a network's computing power, enabling manipulation |
| Blockchain trilemma | The challenge of achieving decentralization, security and scalability simultaneously |
Two corrections to make before your first review
Fix the FTX card. It says the exchange was valued at $18 billion. That was its mid-2021 figure; the valuation that made the November 2022 bankruptcy a landmark was the $32 billion peak reached in January 2022. Edit the back, and add the date to the Terra/Luna card the same way — collapse cards are only useful if the numbers survive scrutiny.
Date the consensus cards. The deck teaches PoW and PoS as neutral alternatives and defines Ethereum purely by smart contracts, with no mention of The Merge (September 2022), when Ethereum switched from proof-of-work to proof-of-stake. Add that sentence to the Ethereum card yourself; otherwise you will memorize a network that no longer exists as described.
A study order that actually works
Do not shuffle on day one. Learn the cryptography-and-consensus cards first — hash, public/private key, PoW, PoS, double-spending, 51% attack — because every later card silently assumes them: a wallet card makes no sense until you know it stores keys, not coins. Once those are automatic, shuffle freely; the coin, wallet and DeFi cards are independent trivia.
If you have already worked through YS4856 — Crypto Trading, DeFi & Tokenomics, expect around a dozen overlapping cards (staking, yield farming, DeFi, PoW). Suspend the duplicates in whichever deck you started second so your review count stays honest: Memorize Crypto and DeFi Fundamentals.
