The Language of Crypto: Time to Learn the Basics 📚

# A

Asset

In a crypto wallet, an asset is basically anything digital—like cryptocurrencies or tokens—that has value and can be used, traded, or transferred. It represents ownership or rights over something digital, and you can trade these assets for regular currencies like the dollar.

They use blockchain technology, making them secure and easy to manage, letting you store or move your digital value with confidence.

Address

Much like a home address in the real world or a web address online, a blockchain address is a unique string of text that helps identify a specific place or user on the blockchain.

It's essentially the location of a particular wallet, and it's what you use to send or receive digital assets. Just like giving someone your home address to send mail, you share your blockchain address when you want to receive crypto or other digital assets.

Altcoin

Altcoins are cryptocurrencies developed as alternatives to Bitcoin and, in some cases, Ethereum. While they aim to improve on Bitcoin's limitations, they face notable insecurities. Many altcoins suffer from low liquidity, smaller market caps, and unclear use cases, making them vulnerable to price volatility and scams.

Additionally, some altcoins lose developer support, leading to abandonment and financial losses for investors. With a wide variety available, it's crucial to thoroughly research each altcoin before investing to avoid these risks.

Application Programming Interface (API)

An API (Application Programming Interface) is a tool that allows different software applications to easily share information and interact, even if they are built using different technologies.

For example, an aggregator site uses APIs to request data from hotel systems to show available rooms. APIs save developers time by letting them use existing features, like Google Maps, instead of building everything from scratch.

They are widely used in various industries, including cryptocurrency, where they enable features like payment processing and algorithmic trading.

Aave

Aave is a platform where people can lend and borrow cryptocurrencies without needing a bank or middleman. Users can deposit their crypto into Aave to earn interest, or they can borrow crypto by providing other crypto as collateral. Aave runs on blockchain technology and uses smart contracts to automatically handle these transactions, making it a decentralized and transparent way to manage loans.

# B

Backup

A backup is a secure copy of your wallet's private key or seed phrase, which ensures you can recover your funds if you lose access to your device or wallet.

Safeguarding this backup is critical, as losing it may result in permanent loss of access to your cryptocurrency. Always store backups in a secure, offline location.

BEP-20

BEP-20 is a token standard on the Binance Smart Chain (BSC), similar to Ethereum's ERC-20, that defines how tokens can be created, transferred, and used.

It allows for the development of various digital assets, such as cryptocurrencies, and supports decentralized applications. BEP-20 tokens can be easily traded and are compatible with both Binance and Ethereum ecosystems.

Biometric authentication

Biometric authentication uses your unique physical traits, like your face or fingerprint, to verify your identity.

Walletium use both face and fingerprint recognition for added security. This ensures that only you can access your wallet in a quick and convenient way, without needing to remember a password.

Binance

Binance is one of the largest cryptocurrency exchanges in the world, offering users the ability to trade a wide variety of digital assets like Bitcoin, Ethereum, and many others. It provides advanced trading tools, staking options, and features for both beginners and experienced traders.

Binance also supports decentralized finance (DeFi) services, earning opportunities, and its own native token, BNB. With a user-friendly interface and strong security measures, it's a popular platform for global crypto enthusiasts.

Bitcoin

Bitcoin is a digital currency that allows people to send and receive payments over the internet without needing a bank or government. It operates on a decentralized network called blockchain, where transactions are securely recorded and verified by a network of computers.

Bitcoin is protected by cryptography, making it secure and resistant to fraud. It was created in 2009 by an anonymous person or group using the name Satoshi Nakamoto.

Blockchain

A blockchain is a secure, digital record that keeps growing by adding blocks of data, all linked together using cryptography. It was first created in the 1990s to protect digital documents from being tampered with, and later became the foundation for Bitcoin, the first decentralized cryptocurrency.

Blockchain works through a network of computers that verify and record transactions, making it safe from fraud and censorship. While it's mostly known for cryptocurrencies, blockchain can also be used in other areas like healthcare and supply chains to keep data secure and lower costs.

Binance Smart Chain (BSC)

Binance Smart Chain (BSC) is a blockchain platform created by Binance, designed for running smart contracts and decentralized applications (dApps). It's similar to Ethereum but aims to be faster and cheaper to use by lowering transaction fees and increasing speed.

BSC allows developers to build and users to interact with decentralized finance (DeFi) projects, tokens, and more, making it a popular choice for blockchain-based activities.

# C

Cold storage

Cold storage refers to storing your cryptocurrency's private keys offline, making it much more secure from hacking or online threats.

In the context of cold crypto wallets or addresses, these methods remove the keys from any internet-connected device, ensuring high security, even though they might be a bit less convenient to access.

Coin

A cryptocurrency coin is a digital currency that runs on its own blockchain, like Bitcoin or Litecoin, and is mainly used as a medium of exchange or store of value. Unlike tokens, which serve specific functions within platforms, coins are used for transactions within their own network.

Coins can be traded for other cryptocurrencies, and many projects start by raising funds through tokens, which can later be swapped for native coins when their blockchain is built.

Cryptocurrency

A cryptocurrency is a digital currency secured by cryptography, typically used for peer-to-peer transactions without the need for intermediaries like banks. Bitcoin, the first cryptocurrency, was created in 2009 by Satoshi Nakamoto to enable decentralized, direct digital payments.

Most cryptocurrencies operate on decentralized networks maintained by distributed computers (nodes) and use blockchain technology to securely record all transactions. The rules governing each cryptocurrency are defined by its underlying protocol, which ensures the system runs securely and efficiently.

Crypto Protocol

A crypto protocol is a set of rules that governs how participants interact in a decentralized network, using cryptography to secure transactions. These protocols are open-source and decentralized, meaning no single authority controls the network, and participants validate transactions collectively.

An example is Bitcoin, where the Proof of Work consensus algorithm allows users to transfer money without needing a bank. Crypto protocols are key to decentralized finance (DeFi), which aims to create financial systems that operate independently of traditional banks and institutions.

Chainlink platform

Chainlink is a decentralized platform that connects smart contracts with real-world data by using "oracles." It allows blockchain-based applications to access external information, like stock prices or weather data, which is crucial for making smart contracts more useful.

Chainlink helps ensure the data provided is secure and reliable, enabling smart contracts to interact with the outside world in a trustworthy way.

Centralized

Centralization refers to a system where decision-making is concentrated in one central authority, while decentralization distributes decision-making across multiple points without a central power. Centralized systems offer clear, fast decisions and defined roles but may suffer from miscommunication, corruption, and exclusion of local expertise.

Bitcoin introduced the possibility of a decentralized network that can reach consensus without these drawbacks, sparking more debate about the benefits of decentralized versus centralized systems.

Custody

In finance, custody refers to an institution holding assets on behalf of a client to protect them from theft or loss, typically for a fee. In cryptocurrency, custodial solutions involve a third party managing users' private keys and funds, which can be convenient but comes with risks if the custodian is compromised.

While custodians play an important role in managing and securing assets, users should consider cold storage for larger amounts of funds that aren't actively in use.

CVV

A CVV (Card Verification Value) is a three- or four-digit security code found on credit or debit cards, usually on the back. It's used to verify that the person making an online or phone purchase physically has the card, adding an extra layer of protection against fraud.

The CVV helps ensure secure transactions by preventing unauthorized use of card numbers alone.

# D

DeFi

DeFi, or decentralized finance, is a system that allows people to access financial services like lending, borrowing, and trading without relying on traditional banks or intermediaries. It uses blockchain technology and smart contracts to create open, transparent, and accessible financial products.

With DeFi, users maintain control of their assets and can participate in a global financial network directly, all while reducing the need for third parties. This opens up financial opportunities to anyone with an internet connection.

Daemon

A process operating in the background waiting for a specific event or condition in order to be activated.

Diversification

Diversification in financial markets means spreading investments across different assets, such as stocks, bonds, or cryptocurrencies, to reduce risk. The goal is to minimize losses by ensuring that positive returns from some assets can offset negative returns from others.

A diversified portfolio tends to be more stable over time, especially when it includes assets with low or negative correlations. While diversification can reduce the risk of losing everything, it also limits the potential for large gains from any single investment.

Decentralization

In the crypto world, decentralization means that control and decision-making are spread across a network of users rather than being held by a single central authority, like a bank or government.

This allows cryptocurrencies to operate independently, with transactions verified by a network of computers (nodes) instead of one controlling entity. Decentralization enhances security, reduces censorship, and allows for more transparent systems.

DApp (Decentralized Application)

A dApp (Decentralized Application) is a type of software that operates on a decentralized network, typically using blockchain technology and smart contracts.

Unlike traditional apps, dApps run without centralized control, making them more transparent, secure, and resistant to censorship. These applications often enable peer-to-peer interactions and are used in various sectors, including finance, gaming, and social platforms.

Digital wallet

A digital wallet is a software or app that stores payment information, like credit card details or cryptocurrencies, allowing users to make transactions online or in stores. It securely holds digital currencies or tokens and can be used to send, receive, or manage funds.

Digital wallets are convenient for both traditional and cryptocurrency payments, offering a secure and easy way to handle digital money.

DAI

DAI is a type of cryptocurrency called a stablecoin, which means it's designed to always be worth about $1. What makes DAI special is that it's not backed by a bank but by other cryptocurrencies. This keeps it decentralized, meaning no one person or company controls it. People use DAI to trade or save money without worrying about big price changes.

Domain Name System (DNS)

The Domain Name System (DNS) is like the internet's phonebook.

When you type a website name, like "google.com," DNS helps your computer find the exact address (IP address) where that website is stored. Without DNS, you'd have to remember long strings of numbers instead of easy names for your favorite websites. It makes browsing the web simple and fast.

# E

Encryption

Encryption is the process of converting data or information into a secure code, making it unreadable to unauthorized parties. It is widely used by wallets to protect private keys, ensuring that sensitive information remains safe from potential threats.

By encrypting data, only those with the correct decryption key can access the original information, enhancing security in digital systems.

Etherium

Ethereum is a decentralized blockchain platform that allows developers to build and run smart contracts and decentralized applications (dApps). Unlike Bitcoin, which is mainly a digital currency, Ethereum's main feature is its ability to support programmable contracts and applications, giving it a wide range of uses.

Ether (ETH) is the platform's native cryptocurrency, used to pay for transactions and services on the network.

ERC-20 and ERC-721

These are two different types of tokens on the Ethereum blockchain.

ERC-20 tokens are fungible, meaning each token is identical and can be exchanged one-for-one, like cryptocurrencies. ERC-721 tokens, on the other hand, are non-fungible (NFTs), meaning each one is unique and cannot be swapped equally, representing things like digital art or collectibles.

The key difference is that ERC-20 tokens are used for currencies and utilities, while ERC-721 tokens represent individual assets.

Ethereum Name Service (ENS)

The Ethereum Name Service (ENS) works like a username system for the Ethereum blockchain. Instead of having to use long, confusing wallet addresses (similar to long serial numbers), ENS lets you use simple, human-readable names like "alice.eth."

This is like giving your friend a short nickname instead of having to remember their full phone number—it makes sending cryptocurrency and using blockchain apps much easier.

# F

Fork

A fork is an update or modification to a blockchain's protocol or underlying code. Forks can be "soft," meaning they are backward-compatible and allow the updated blockchain to work with the previous version.

Alternatively, they can be "hard," where the changes are not compatible with the older version, potentially creating a new, separate blockchain. Forks are often used to implement upgrades, fix bugs, or resolve disputes within the blockchain community.

Fiat

Fiat money is a currency that has no intrinsic value and is not backed by a physical commodity like gold. It gets its value from government regulation, which declares it legal tender, and from society's collective belief in its worth as a medium of exchange.

Fiat money is widely accepted as payment, but its value depends on government backing and public trust. If either of these is compromised, the currency can lose value rapidly, potentially leading to inflation or hyperinflation.

# G

Genesis Block

The Genesis Block is the first block in any blockchain, serving as the foundation for all future blocks. It marks the starting point of the blockchain network and is unique because it doesn't reference any previous blocks, unlike all other blocks that come after it.

Every blockchain begins with a genesis block, which sets the initial conditions for the network.

Gas

Gas is the unit used to measure the amount of computational work required to perform transactions or run smart contracts on the network. While fees are paid in native currency, or a small fraction of it, gas determines how much "work" a task needs, and the gas price sets the cost for each unit of that work.

Higher gas prices incentivize validators to process transactions faster. This system ensures fair fees and prevents the misuse of network resources.

Gas Limit

The gas limit on a network sets the maximum amount a user is willing to pay for a transaction or smart contract function, acting as a safeguard against excessive fees. While higher gas limits can speed up transactions, they also come with higher costs.

The actual fee paid is determined by multiplying the gas price by the gas limit, with the gas price playing a more important role in the overall cost. Some wallets automatically set these values, but users can adjust them based on their needs.

# H

Hash

A Hash is a function that takes any kind of data and transforms it into a fixed-length string of characters. This string acts like a digital fingerprint, securely representing the original data.

Hashes are widely used in blockchain and other systems to verify data integrity, ensuring that even a tiny change in the original data results in a completely different hash.

Hardware Wallet

A Hardware Wallet is a small physical device that keeps your private keys securely stored offline, making it one of the safest options for storing cryptocurrency. Since it's not connected to the internet, it's much less vulnerable to hacks or malware.

Many people use hardware wallets to protect their digital assets while still having convenient access when needed.

# I

Immutable

Immutable refers to the fact that once data is recorded on a blockchain, it cannot be changed or tampered with. This ensures the integrity and security of the information, making blockchain a trusted system for storing and verifying data. Once something is added to the blockchain, it stays there permanently.

Inter-Blockchain Communication (IBC) protocol

The Inter-Blockchain Communication (IBC) protocol allows different blockchain networks to communicate and exchange data with each other.

It enables seamless transfer of assets and information across separate blockchains, promoting better interoperability and connectivity. IBC is essential for creating a more connected ecosystem where multiple blockchains can work together efficiently.

# J

Jumbo Transaction

A Jumbo Transaction refers to a large transaction involving a substantial amount of cryptocurrency. These transactions often stand out due to their size and can sometimes attract attention within the network.

They typically involve large sums of money, making them significant in the world of digital finance.

JSON (JavaScript Object Notation)

JSON (JavaScript Object Notation) is a simple, lightweight format used to store and exchange data. It's commonly used in blockchain technology to store wallet information or interact with blockchain APIs. JSON is easy for both humans and machines to read, making it a popular choice for transferring data between systems.

# K

Key

A Key can refer to either a public key or a private key. The public key acts like a shareable address, allowing others to send you cryptocurrency. The private key, on the other hand, must be kept secret, as it is used to authorize and sign transactions.

Together, these keys ensure secure and efficient transactions on the blockchain.

Know Your Customer (KYC)

KYC (Know Your Customer) is a process used by banks and financial institutions to verify the identity of customers to prevent fraud and money laundering. It involves collecting documents like IDs and proof of address before opening accounts, with regular updates over time.

While KYC helps combat illegal activities, it can be time-consuming but necessary for security. In cryptocurrency exchanges, KYC is often required to access full account features, helping reduce fraud and improve trust in the system.

# L

Ledger

A Ledger is a system, either physical or digital, that tracks and records transactions. In the context of blockchain, it refers to the distributed ledger, which is a shared and decentralized record of all transactions across the network.

This ensures transparency and security, as the ledger is updated and verified by multiple participants.

Liquidity

Liquidity refers to how easily an asset, like cryptocurrency, can be converted into cash or another cryptocurrency without significantly impacting its price.

High liquidity means you can buy or sell the asset quickly, while low liquidity might make transactions slower or cause price fluctuations. Liquidity is important for smooth trading in any market.

Listing

When an exchange lists an asset, it means that the asset can be traded on that platform. In traditional markets, this indicates that a company’s shares have met certain financial and regulatory standards.

In cryptocurrency exchanges, listing a digital asset, especially with major trading pairs like Bitcoin or Ethereum, shows trust in the project and ensures there is enough liquidity to accurately determine its price.

# M

Multisig

Multisig (Multisignature) is a type of wallet that requires more than one private key to approve a transaction, providing an additional layer of security.

Instead of relying on a single key, multiple parties must agree before a transaction can be completed. This makes multisig wallets a popular choice for enhancing security in both personal and business crypto transactions.

Mnemonic Phrase

A Mnemonic Phrase is a set of 12 to 24 words that acts as a backup for your crypto wallet. This phrase allows you to recover your wallet if you lose access to it. It's essential to store your mnemonic phrase safely, as anyone with it can gain full access to your funds.

Monero

Monero is a privacy-focused cryptocurrency designed to offer secure, untraceable transactions. Unlike other cryptocurrencies, Monero uses advanced cryptography to hide transaction details like sender, receiver, and amount, making it highly private. It’s popular among users who prioritize confidentiality and anonymity in their digital transactions.

Meme Coin

A meme coin is a type of cryptocurrency that starts as a joke or is inspired by internet memes, like funny pictures or trends. Even though they begin as fun, some meme coins, like Dogecoin, become popular and valuable because people enjoy them or invest in them for fun. They can be more unpredictable than other cryptocurrencies since they rely a lot on social media buzz and community support.

# N

Node

A Node is a computer that plays a role in a blockchain network by validating and sharing transactions. Some nodes, known as full nodes, store the entire history of the blockchain, ensuring the network’s integrity and security. Nodes help keep the blockchain decentralized and functioning smoothly.

Nonce

A Nonce is a unique number used in cryptography and blockchain mining to ensure that previous transactions can't be changed. In mining, it's adjusted repeatedly until the correct value is found to validate a block. This process adds security to the blockchain by preventing tampering with past data.

Native Token

A native token is the main cryptocurrency used by a blockchain platform. It serves as the primary currency for transactions, paying fees, and securing the network.

For example, Ether (ETH) is the native token of the Ethereum blockchain. Native tokens are essential to the functioning and governance of their respective blockchains.

Non-Fungible Token (NFT)

A non-fungible token (NFT) is a unique digital asset that represents ownership and authenticity of an item on a blockchain. Unlike regular currencies or cryptocurrencies, NFTs are not interchangeable because each one is distinct.

They are used for owning and trading digital collectibles, art, and other assets, with the most common standard being ERC-721 on the Ethereum blockchain. NFTs have potential applications in areas like gaming, digital identity, and licensing, offering secure ownership and easy transfers of assets.

NFT Phone Number

An NFT phone number refers to a unique, non-fungible token (NFT) ID tied to an individual in a collection.

Similar to how an NFT acts as a digital certificate of ownership, this ID ensures that the phone number or identification is one-of-a-kind and secured on the blockchain, like Ethereum, giving it a distinct value and identity in the digital world.

Non-custodial

Non-custodial refers to a type of service or wallet in the crypto world where you, the user, have full control over your own assets. This means that no third party, like a company or exchange, holds or manages your funds for you.

Instead, you are responsible for your own private keys (the secret codes that give access to your cryptocurrency), which gives you more freedom and security but also means you need to be careful to keep those keys safe.

# O

Offline Transaction

An Offline Transaction is a transaction that is signed on a device that isn't connected to the internet, providing extra security. This method is often used with hardware wallets to protect private keys from online threats.

Once signed, the transaction can be broadcast to the network from a connected device.

Open Source

Open Source software is code that anyone can view, modify, or share.

In the crypto world, many wallets are open source to provide transparency and allow the community to verify security. This openness helps build trust, as users can see exactly how the software works.

OTP

OTP, or One-Time Password, is a security feature that generates a unique code for a single-use login or transaction. It adds an extra layer of protection by requiring this temporary password, usually sent via SMS or email, in addition to the regular password. Since OTPs expire after use or a short time, they help prevent unauthorized access to accounts.

# P

Private Key

In cryptocurrency, a private key is a secret number that lets users sign transactions and generate receiving addresses. It’s essential for securing funds, as anyone with access to a private key can control the associated assets.

While the public key can be shared to receive funds, the private key must always be kept secret. Modern wallets often use seed phrases as backups for private keys, and hardware wallets are considered the safest option for storing them.

Public Key

A Public Key is a cryptographic code connected to your wallet address that you can safely share with others. It allows people to send funds to your wallet, but it doesn't give them access to your assets.

Think of it like an email address for receiving cryptocurrency—secure to share, but it doesn’t expose your private information.

Peer-to-Peer (P2P)

Peer-to-peer (P2P) is a decentralized network structure where tasks are shared across multiple computers, or nodes, with each acting as both a client and a server. Unlike traditional client-server models, P2P networks have no central authority, making them more secure and scalable.

P2P technology is widely used for sharing digital data, and it's a key part of blockchain and cryptocurrencies like Bitcoin, allowing users to send and receive funds directly without intermediaries.

Proof of Work (PoW)

Proof of Work (PoW) is a consensus mechanism used in blockchain networks, like Bitcoin, where miners solve complex puzzles using computational power to validate transactions and create new blocks. The first miner to solve the puzzle adds the block and earns rewards.

PoW offers strong security, as disrupting the network would require controlling more than 50% of the computational power. However, it’s criticized for its high energy consumption, leading to the development of more efficient alternatives like Proof of Stake (PoS).

Proof of Stake (PoS)

Proof of Stake (PoS) is a consensus mechanism where validators are selected to create new blocks based on the number of coins they stake, acting as collateral. Validators earn rewards for honest behavior, while malicious actors risk losing their stake.

PoS offers a more energy-efficient and scalable alternative to Proof of Work (PoW), which relies on costly computational power. PoS systems can increase decentralization and security, and there are variations like Delegated PoS and hybrid PoW/PoS models.

Phishing

Phishing is a common cyber attack where criminals trick people into giving away sensitive information, like passwords or credit card details, by pretending to be a trustworthy entity. This often happens through fake emails and websites that look real.

In cryptocurrency, phishing scams can lead to stolen funds by redirecting payments to the scammer’s wallet. To avoid phishing, always verify requests for sensitive information, avoid clicking suspicious links, and double-check blockchain addresses before sending payments.

Proof of Staked Authority (PoSA)

Proof of Staked Authority (PoSA) is a way to keep a blockchain network safe and running smoothly.

It combines two ideas: "proof of stake," where people who own and lock up some of their coins can help run the network, and "authority," meaning only selected, trusted people can create new blocks. This system helps make the network faster and more secure by using both coins and trust.

Polkadot

Polkadot is a blockchain platform designed to connect different blockchains so they can work together. Instead of operating in isolation, Polkadot allows various blockchains (called "parachains") to share information and security, making them more efficient and powerful.

It's like a network of roads that connects different cities, allowing them to easily communicate and exchange resources. Polkadot's goal is to create a more interconnected and scalable ecosystem for blockchain technology.

# Q

QR Code

It's a convenient and error-free way to transfer crypto details.

Quorum

A Quorum is the minimum number of participants or validators needed to reach a decision or agreement in a decentralized network. It ensures that enough members are involved to validate a transaction or make changes to the system. This helps maintain the security and fairness of the network.

# R

Recovery Phrase

A Recovery Phrase, also known as a mnemonic phrase, is a set of words used to restore access to a lost crypto wallet. It acts as a crucial backup, so it's important to store it securely. Anyone with access to this phrase can recover your wallet and its funds, so keeping it safe is essential.

# S

Stablecoin

A stablecoin is a cryptocurrency created to keep its value steady by being linked to an asset like the US dollar, gold, or other cryptocurrencies.

Unlike other digital currencies, stablecoins are designed to minimize price fluctuations, making them more suitable for regular transactions. By pegging their value to real-world assets, they help avoid the sharp price changes often seen in other cryptocurrencies.

Seed Phrase

A seed phrase is a set of 12-24 random words that acts as a backup for your cryptocurrency wallet. If you lose access to your wallet, you can use the seed phrase to recover your funds in any compatible wallet.

It’s more secure and easier to record than private keys, and it can generate multiple addresses from a single master key. Seed phrases are widely used across different cryptocurrencies, making it possible to recover an entire portfolio with one phrase.

Smart Contract

Smart contracts are self-executing contracts on blockchain networks that automatically enforce agreements based on predefined conditions written in code. They eliminate the need for intermediaries, offering benefits like automation, transparency, security, and cost efficiency.

Commonly used in industries like finance, supply chain, and insurance, smart contracts speed up processes and reduce manual intervention. However, they also face challenges such as code vulnerabilities and reliance on external data, which the community continues to address through audits and development efforts.

# T

Transaction Fee

A Transaction Fee is a small amount paid to miners or validators when you send cryptocurrency. This fee helps prioritize and process your transaction quickly on the network. The higher the fee, the faster your transaction is likely to be confirmed.

Token
