Crypto Lingo 101: Key Terms and Definitions
Cryptocurrency
Cryptocurrencies are digital or virtual currencies that use cryptography to ensure security without the involvement of a central bank. Cryptography is a process that converts readable information into an almost unbreakable code to track transactions. Cryptocurrencies usually operate on a decentralized system, which means any government or financial institution doesn’t regulate them.
Blockchain
The concept of a blockchain involves a digital ledger that is decentralized and records transactions in a secure manner. To achieve this, a network of computers is used to maintain blocks that contain timestamped transaction data and a cryptographic hash of the preceding block. As a result, falsifying or altering data on the blockchain is challenging due to its distributed or decentralized nature.
Altcoin
Altcoins are cryptocurrencies that are not Bitcoin. They are often created to offer an alternative to Bitcoin or to solve problems that Bitcoin cannot. Ethereum, Litecoin, and Ripple are some examples of altcoins.
Stablecoin
Stablecoin is a cryptocurrency with a consistent value fixed to a fiat currency or commodity. Its main purpose is to decrease the instability of cryptocurrencies like Bitcoin, making them more practical for everyday transactions. To sustain their stable value, stablecoins are typically supported by reserves or algorithms.
Mining
Mining is the process of creating and verifying new cryptocurrencies on a blockchain network. This involves using specialized computers to solve complex mathematical problems and validate transactions. Miners are then rewarded with newly created units of cryptocurrency for their work.
NFT
A non-fungible token (NFT) is a one-of-a-kind digital asset that signifies ownership of a particular item or content, like music or artwork and is kept on a blockchain. NFTs are now popular among artists and collectors because they offer a new way to earn money and possess exclusive digital content.
Meme Coin
Meme coins are a category of cryptocurrency inspired by memes, jokes, or cultural references rather than practical applications. Usually, they are created to satirize established cryptocurrencies or to capitalize on a viral internet trend. Meme coins have many supporters and can observe significant price changes depending on social media hype and market feelings. Dogecoin, Shiba Inu, and SafeMoon are some examples of meme coins.
Shitcoin
In the cryptocurrency world, “shitcoin” is a term people use to criticize a cryptocurrency with little to no worth or practical purpose. These cryptocurrencies usually emerge as get-rich-quick schemes or scams and are known to be extremely unpredictable and carry a significant financial danger.
Wallet
A cryptocurrency wallet is a digital storage or service where users can securely store their cryptocurrency and perform transactions. These wallets can take different forms: online, offline, software-based, or hardware-based. Generally, they store the private key necessary to access and transfer their funds.
Public key
A public key is a specific identification code for cryptocurrency transactions that can be shared with others. It functions similarly to a bank account number and is utilized for receiving cryptocurrency payments.
Private key
The private key is like a password enabling cryptocurrency wallet owners to manage and move their funds. The private key should be kept confidential to maintain security because whoever has it can access the funds in the wallet.
Decentralization
In cryptocurrency, decentralization means power and decision-making are not concentrated in a single entity, such as a government or financial institution. Instead, it is distributed among a network of individuals.
ICO
An Initial Coin Offering (ICO) is a way for new cryptocurrency projects to raise funds by selling a new cryptocurrency or token to investors in exchange for established cryptocurrencies or fiat currency. The tokens sold in an ICO typically represent a share of the project or a future utility within its platform.
Smart contracts
Smart contracts are contracts in which the terms of the agreement between buyer and seller are directly written into lines of code. They can automate the transfer of cryptocurrency funds and enforce the terms of the agreement without needing a third party. Smart contracts are executed on a blockchain network, guaranteeing their security and tamper-proof nature.
Nodes
In a blockchain network, nodes are computers or devices that verify and validate transactions. By maintaining a copy of the blockchain ledger, nodes work together to ensure the integrity of the blockchain.
Crypto exchanges
Crypto exchange platforms enable users to buy, sell, and trade cryptocurrencies. These exchanges usually provide various cryptocurrency pairs and may have transaction fees.
Tokens
Digital tokens are assets that are created and managed through a blockchain network. They can represent various things of value, such as commodities, assets, or access to a particular service. These tokens are tradable on crypto exchanges and can grant access to specific features or services within a blockchain network.
Fungibility
Fungibility pertains to how easily an asset can be swapped with other assets with equivalent worth and type. In relation to cryptocurrency, fungibility denotes the capability of a unit of cryptocurrency to be swapped with other units of the same cryptocurrency. Hence, each cryptocurrency unit should hold an identical value and should not be distinguishable from any other unit of the identical cryptocurrency.
Proof of Work (PoW)
The PoW consensus algorithm was initially used in Bitcoin and other cryptocurrencies. It works by solving mathematical problems to validate transactions and add new blocks to the blockchain. The miner who solves the problem first gets new coins. However, PoW needs a lot of computational power and energy, which can be disadvantageous.
Proof of Stake (PoS)
The PoS consensus algorithm is designed to decrease energy usage and improve transaction speed. To participate, users hold a specific amount of cryptocurrency as a stake and use it to authenticate transactions and create new blockchain blocks. Validation is based on the amount of stake held, and rewards are given accordingly.
Decentralized Apps (DApps)
DApps, or decentralized applications, are software programs that run on a peer-to-peer network using blockchain technology. They are constructed without a central figure and utilize smart contracts to carry out their actions. DApps can be created for various functions and operate independently without any central party’s involvement.
HODL
The term HODL is known in the cryptocurrency community and came from a misspelling of “hold.” It means holding onto cryptocurrency instead of selling it for short-term profits. People use the term to promote a patient approach to investing and inspire others to hold onto their cryptocurrency investments, despite market fluctuations. The term has gained popularity and is often used in memes and online forums.
FOMO
“FOMO” means “Fear Of Missing Out.” It happens when someone gets anxious or worried that other people are enjoying something desirable that they are not. In the case of cryptocurrency, FOMO is often used to describe the fear of missing a chance to make money, which can cause some investors to make impulsive and irrational choices based on hype or speculation. FOMO is risky for investors because it can cause them to make bad decisions and lose a lot of money.
