The Crypto Glossary is the go-to resource for crypto enthusiasts looking to stay up-to-date on the latest blockchain technologies and trends. Our Crypto Glossary provides an easy way to learn about the complex world of cryptography and blockchain technology, with short, clear definitions of all the most important concepts.

Here are some of the key terms you’ll find in our Crypto Glossary:

• Bitcoin – The original cryptocurrency, created as a decentralized, peer-to-peer currency system that allows users to send money directly without any middleman or intermediary involved.

• Blockchain – A digital ledger that keeps continuous track of all transactions made using a particular cryptocurrency. This decentralized ledger can also be used to store other types of information as well, such as smart contracts or votes.

• Cryptocurrency – Digital currency based on cryptographic principles, like Bitcoin or Ethereum. Transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain.

• Smart Contract – A computer protocol intended to facilitate, verify, or enforce the negotiation or performance of a contract digitally. Smart contracts allow users to create automated processes that don’t require middlemen and reduce transaction fees significantly compared with traditional methods of doing business online.

• Mining – The process by which new blocks are added to a blockchain network; miners use computer processing power to solve complex computational problems (called ‘proof-of-work’) before they can be rewarded with newly created coins from the network itself.

These are just some of the essential terms in our comprehensive Crypto Glossary hosted on! No matter what level crypto enthusiast you are – beginner, intermediate or expert – if you need help understanding any concept related to cryptocurrency and blockchain technology, look no further than CloudCoda’s Crypto Glossary!



A unique identifier that enables users to send and receive cryptocurrencies, which typically consist of a string of letters and/or numbers. A typical cryptocurrency address is both case sensitive and unique to a specific user, making it difficult for others to access their funds.


Any cryptocurrency that is not Bitcoin. As the number of cryptocurrencies continues to grow, altcoins have become an increasingly important part of the cryptocurrency ecosystem.


Application-Specific Integrated Circuit is a hardware device specifically designed to mine cryptocurrencies such as Bitcoin. Unlike CPUs, GPUs, or FPGAs, ASICs are more powerful and efficient at solving mining algorithms, which makes them more effective at generating hash power.



A group of verified cryptocurrency transactions that are added to a blockchain. Each block contains a unique identifier (hash), along with information that indicates its position in the chain of blocks. Once a block is added to the blockchain, it is considered as immutable and cannot be altered.


A decentralized, digital public ledger that records and stores all cryptocurrency transactions in chronological order. Each new transaction is verified and added to the blockchain using complex mathematical algorithms that are solved by a network of computers. Blockchain technology enables instant and secure transactions between two parties without the need for intermediaries.



CoinBase is a platform that facilitates the direct and secure exchange of gifts, money, or other digital assets between user accounts. It operates as an online wallet for users to store, send, and receive digital currency quickly and securely. CoinBase also serves as a broker for digital currencies, providing access to multiple exchanges to buy and sell cryptocurrencies with credit/debit cards, bank transfers, or wire transfers.

Cold Storage

A practice of storing cryptocurrency funds offline, which provides an additional layer of security beyond online storage. Cold storage typically involves the use of a hardware wallet, a device that stores cryptocurrency private keys and can be used to sign transactions without ever exposing the keys to the internet.


The process of verifying that a cryptocurrency transaction has been added to the blockchain. In general, each new block added to the blockchain provides an additional confirmation that a transaction has occurred.


The art of creating secure communication channels that prevent unauthorized access, also used in cryptocurrencies to secure transactions and prevent counterfeiting.


A digital or virtual currency that utilizes cryptography to secure and verify transactions and to control the creation of new units. Cryptocurrencies are commonly designed to be decentralized, meaning they operate without a central authority or intermediary like a bank.



A system or network that is not controlled by a single central authority or organization, and instead rely on a global network of users to run the system or network. Decentralization is a key feature of most cryptocurrencies, which enable secure transactions without the need for intermediaries such as banks, credit card companies, or financial institutions.



A platform where users can buy, sell, or trade cryptocurrencies. Cryptocurrency exchanges are typically online platforms that allow users to exchange one cryptocurrency for another or exchange cryptocurrencies for fiats like USD or EUR.


Fiat Currency

A government-issued currency which is legal tender and widely accepted for transactions, such as USD or EUR.


The Fear Of Missing Out, when people feel the urge to invest in cryptocurrency due to the fear of losing out on potential investment profit. FOMO may also be a driving factor behind market bullishness, as new investors rush to buy into a rising market in order to avoid missing out on potential profits.


A change to the underlying code or software of a cryptocurrency that can result in the creation of two separate blockchains and separate cryptocurrencies. Forks may be initiated as a result of differences in opinion amongst the cryptocurrency community on the direction of a particular cryptocurrency, and can often result in a community split.



The unit of measurement for the amount of computational effort or computational resources that are required to execute a smart contract on the Ethereum network. The amount of gas a contract requires may vary depending on the complexity of the contract.



A unique digital fingerprint that represents a block of data in a blockchain. The hash is a fixed length sequence of bytes which is calculated using a cryptographic hash function.


Holding on for dear life, a strategy of holding onto cryptocurrency instead of selling it during price dips to avoid losses.



Initial Coin Offering, a crowdfunding method for new cryptocurrency startups where investors receive tokens as an investment in the startup’s ecosystem.



Know Your Customer, a process that involves verifying the identity of individuals and businesses before they can use cryptocurrency services, to avoid fraud and money laundering.


Lightning Network

A layer-2 protocol created to enable faster and cheaper transactions between two parties in a cryptocurrency network, and enable micropayments or other payments that aren’t currently feasible on chain.


Market Cap

The total value of all the coins or tokens of a cryptocurrency in circulation. Market cap is calculated by multiplying the total supply of cryptocurrency by its current price.


The process of verifying transactions and adding them to the blockchain. This is done by using a computer’s processing power to solve complex mathematical problems or puzzles that are required to mine coins in a process called proof-of-work.



A computer or network-connected device that participates in verifying cryptocurrency transactions, which is necessary to maintain the security and decentralization of the network.


Orphaned Block

A block that was once part of the blockchain but has been discarded because it did not meet the consensus rules of the cryptocurrency network. Orphaned blocks may occur in situations where multiple blocks are produced at approximately the same time.


Private Key

A secret code that allows access to a user’s cryptocurrency wallet, and is required in order to make transactions or access funds.

Public Key

A code that acts as an address for users to receive cryptocurrency, which can be shared publicly in order to receive funds.

Pump and Dump

A fraudulent practice where a group of people artificially inflate the value of a cryptocurrency before selling them at a higher price, thereby making a profit at the expense of unsuspecting buyers.



The smallest unit of Bitcoin, equal to one hundred millionth of a Bitcoin. The unit was named after the anonymous creator(s) of Bitcoin, Satoshi Nakamoto.

Security Token

A type of cryptocurrency that is backed by tangible assets or profits from a tradeable asset, making them similar to traditional financial instruments like stocks, bonds or commodities.


The secure cryptographic algorithm used in mining Bitcoin, which is also used for generating digital signatures and verifying the authenticity of data.

Smart Contract

Self-executing digital contracts that automatically execute and verify the terms of an agreement. Smart contracts often utilize blockchain technology, and can be utilized in a wide range of industries and use cases.


A type of cryptocurrency that is pegged to an external asset, typically a fiat currency like the US dollar, in order to provide greater stability and reduce volatility.



A unit of value that represents a digital asset or rights, often associated with fundraising efforts in an initial coin offering or as a representation of ownership in a specific asset or platform.

Transaction Fee

The cost paid by users to miners to verify and process cryptocurrency transactions, typically based on network congestion and the level of computational effort required to verify the transaction.



A digital storage space that holds cryptocurrencies and allows users to send and receive them. Wallets can be either online (also known as hot wallets) or offline (also known as cold storage wallets).


An individual or group that owns a significant number of cryptocurrencies, and whose trading activity may influence the wider cryptocurrency market.


A document created by a cryptocurrency development team that includes details on the project’s specifications, goals, and implementation plans. Whitepapers provide a detailed technical overview of a cryptocurrency and can be a valuable resource for investors and developers.


Zero Confirmation

A type of cryptocurrency transaction that has not yet been confirmed by the network and included in a block, and is therefore subject to greater risk of being reversed or double-spent. Zero confirmation transactions are typically used for low-value, day-to-day transfers.

Crypto FAQ

Cryptocurrencies are digital assets that use blockchain technology to facilitate secure payments, transfers and exchanges. These digital assets can be used to store value, buy goods, pay for services and more. Cryptocurrencies are decentralized and are not regulated by any central authority like traditional currencies. Instead, the transactions that take place on a public blockchain ledger are secured through cryptography and consensus algorithms.

Trading cryptocurrencies is different from trading stocks in a few key ways. Firstly, most cryptocurrency exchanges operate 24/7, whereas stock markets typically close at night. Secondly, the prices of cryptocurrencies can be much more volatile than stocks due to the lack of regulation and limited liquidity. Finally, the technology behind cryptocurrencies makes it easier to conduct trades on blockchain-based exchanges compared to traditional stock exchanges.

Yes, there are tax implications associated with cryptocurrencies. Depending on your jurisdiction, you may be required to report capital gains or losses when buying and selling cryptocurrencies. The same tax rules that apply to any other type of asset also apply to cryptocurrencies; however, the complexity of tracking transactions makes it more difficult for some people to accurately report their crypto-related activities on their taxes.

Buying crypto is relatively easy with today’s technology. There are a few different ways to purchase cryptocurrencies, including exchanges, peer-to-peer platforms and automated services. On an exchange, you typically need to open an account, verify your identity, deposit funds and then select the cryptocurrency you want to buy. You can also use peer-to-peer platforms such as LocalBitcoins or Paxful to find people willing to sell crypto. Finally, there are automated services like Coinbase which make it even easier for novice users to buy cryptocurrencies.
