7. Hot Wallet: A cryptocurrency wallet that is connected to the internet, making it more convenient for transactions but also more vulnerable to hacking.
8. Paper Wallet: A physical document containing your public and private keys, often in the form of QR codes. Paper wallets are considered a secure way to store cryptocurrency offline, as they are immune to online hacking attempts. However, they can be lost, damaged, or stolen, so it’s important to store them safely.
Transaction Terms
1. Address: A unique identifier used to receive cryptocurrency. It’s similar to a bank account number.
2. Transaction Fee: A small fee paid to miners or validators for processing a transaction on the blockchain.
3. Confirmation: The process of verifying and adding a transaction to the blockchain. A transaction is considered confirmed when it has been included in a block and added to the blockchain.
4. Gas: A unit of measurement for the computational effort required to execute operations on the Ethereum network. Gas fees are paid to miners to incentivize them to process transactions and smart contracts.
5. Hash: A fixed-length string of characters produced by a cryptographic algorithm from input data. Hashing is used to secure transactions on the blockchain.
6. Block Reward: The reward given to miners for successfully validating and adding a block to the blockchain. It typically includes newly created cryptocurrency and transaction fees.
Investment Terms
1. HODL: A slang term derived from a misspelling of “hold,” meaning to keep your cryptocurrency rather than selling it, often used to express long-term investment strategy.
2. FOMO (Fear of Missing Out): The anxiety that one might miss out on a profitable investment opportunity, often leading to impulsive buying decisions.
3. FUD (Fear, Uncertainty, Doubt): Negative information spread to create fear and uncertainty around a particular cryptocurrency or market.
4. Pump and Dump: A scheme where the price of a cryptocurrency is artificially inflated (pumped) through misleading statements, leading to a sharp increase in price, followed by a sale of holdings (dump) to profit, causing the price to crash.
5. Whale: An individual or entity that holds a large amount of cryptocurrency, capable of significantly influencing the market with their trades.
6. ATH (All-Time High): The highest price ever reached by a cryptocurrency.
7. Bear Market: A market condition characterized by declining prices and negative sentiment.
8. Bull Market: A market condition characterized by rising prices and positive sentiment.
Technical Terms
1. Proof of Work (PoW): A consensus mechanism where miners solve complex mathematical problems to validate transactions and add them to the blockchain. Bitcoin uses PoW.
2. Proof of Stake (PoS): A consensus mechanism where validators are chosen based on the number of coins they hold and are willing to “stake” as collateral. Ethereum is transitioning to PoS.
3. Hash Rate: The computational power used to mine and process transactions on a blockchain. A higher hash rate indicates more security and efficiency.
4. Fork: A change or upgrade to a blockchain protocol that creates a divergence in the blockchain. It can result in two separate chains: hard forks (which create a new cryptocurrency) and soft forks (which are backward-compatible upgrades).
5. Node: A computer that participates in a blockchain network by validating and relaying transactions. Nodes keep a copy of the blockchain and help maintain the network’s integrity.
6. dApp (Decentralized Application): An application that runs on a decentralized network, utilizing blockchain technology and smart contracts to function without a central authority.
7. DAO (Decentralized Autonomous Organization): An organization governed by smart contracts and decentralized voting, operating without centralized control.
8. Transaction Hash: A unique identifier generated by a cryptographic algorithm for each transaction. It serves as a reference number for tracking and verifying transactions on the blockchain.
