Glossary

• BitcoinThe very first and most well-known cryptocurrency, created in 2009. It's often seen as digital gold because its supply is limited. For example, someone might buy Bitcoin hoping its value will increase over time, or use it to send money across countries quickly.
• BlockchainA special type of digital record book where all cryptocurrency transactions are stored in a long chain of "blocks." Once a transaction is added to a block, it's very hard to change or remove. For example, imagine a shared diary where every page (block) is filled with new entries (transactions), and once a page is written and sealed, it's added to the previous pages, creating a permanent record for everyone to see.
• Crypto WalletA digital tool or app that lets you securely store, send, and receive cryptocurrencies. It doesn't actually hold the coins themselves, but rather the special keys that prove you own them. For example, just like you keep your physical money in a wallet, a crypto wallet is where you keep the digital "keys" that give you access to your Bitcoin or other cryptocurrencies.
• CryptocurrencyA type of digital money that uses strong computer codes (cryptography) to keep it safe and check that transactions are real. Unlike regular money, it's not controlled by a bank or government. For example, Bitcoin is a cryptocurrency that people can use to buy things online or send money to others without needing a bank in the middle.
• DecentralizationThis means that something, like a cryptocurrency system, is not controlled by one single person, company, or government. Instead, many different computers or people around the world help run it. For example, regular banks are centralized because one company controls your money, but a decentralized cryptocurrency means no single authority can freeze your account or print unlimited money.
• Digital Currency / E-moneyAny form of money that exists only in electronic form and can be used for transactions online or with digital devices. This is a broader term that includes cryptocurrencies but also digital versions of regular money. For example, when you pay for something online using a debit card or use a mobile payment app like Google Pay, you're using digital currency.
• Fiat CurrencyRegular money that a government declares to be legal tender, like the Indian Rupee or US Dollar. Its value comes from people's trust in the government and economy, not from a physical commodity like gold. For example, the cash you use to buy snacks at the store or the money in your bank account is fiat currency, backed by the government.
• Mining (Crypto Mining)The process where powerful computers solve complex math problems to verify and add new transactions to the blockchain, creating new blocks. As a reward, the "miners" sometimes get new cryptocurrency. For example, imagine a competition where computers race to solve a puzzle; the first one to solve it gets to add the next page to the shared diary (blockchain) and earns a small prize.
• StablecoinA type of cryptocurrency designed to have a stable value, usually by being tied to a "real-world" asset like the US Dollar or gold. This helps avoid the big price swings common with other cryptocurrencies. For example, if you want to use cryptocurrency but are worried about its price suddenly dropping, you might use a stablecoin like USDT, which aims to always be worth one US Dollar.
• TransactionAn exchange of cryptocurrency from one person or account to another. Each transaction is recorded on the blockchain. For example, when you send 0.01 Bitcoin to your friend, that's a transaction that gets added to the blockchain for everyone to see (though your identity might be hidden).

Where this connects to other fields, and why it's worth knowing.

• Quantum Computing Technology

  The secret math that locks your crypto wallet could be cracked wide open by a future quantum computer. So some hackers are copying scrambled data today and just sitting on it, waiting for that machine to arrive and unlock it. They call it 'harvest now, decrypt later.'

• Private Law: Contract, Tort & Property Law

  Crypto fans say 'code is law': instead of a promise a court can enforce, a program automatically does the deal for you. Sounds perfect, until a bug in one such program (called The DAO) drained millions of dollars, and everyone had to ask: does the code rule, or what people meant to happen?

• Trade, Money & Economies History

  Bitcoin was built on a neat story: first people bartered, then invented coins to trade more easily. Problem is, anthropologists studying real ancient societies found that story is a myth; money actually started as tracking debts and favors between people, not as swapping goods.

• Game Theory & Strategy Mathematics

  With no bank in charge, why does a cryptocurrency hold together? Because attacking it just doesn't pay off. It's set up so that everyone's best move is to play honestly, a balance mathematicians call a Nash equilibrium, solving the old puzzle of how strangers who don't trust each other still agree.

• Metaphysics Philosophy

  A Bitcoin is worth something only because a crowd of people agree it is. That sounds shaky, until you realize the cash in your pocket works the exact same way. Money was never 'real' on its own; it's real because we all believe together.

• Networks & Graphs Mathematics

  People think Bitcoin is anonymous. Actually every transaction is written on a permanent public list anyone can read, and "chain analysis" experts routinely trace it back to real people. It's one of the least private kinds of money ever invented.
