Lexicon of Crypto Terms

Cryptocurrency has gained plenty of first-time investors in the previous year. In a recent survey hosted by CNBC, 65% of respondents claimed that they only started acquiring decentralized financial tokens in 2020. Forbes also reported that about 15% of adult Americans own cryptocurrencies, and more than half of them got into the asset class last year. This surge in demand just demonstrates how far cryptocurrencies have come since the first decentralized coin, Bitcoin (BTC), was released in 2009.

Despite the recent boom in cryptocurrency trading and mining, would-be investors will find that they still have plenty of promising investment options if they start getting into the cryptocurrency scene today. Still, it’s important to get to know the terms that you’ll encounter as you start buying, selling, or mining cryptocurrency. Before you invest in an ASIC miner, open a Monero wallet, or start exchanging your fiat currency, get to know these frequently used crypto terms first.


A unique identifier that serves as the virtual location where a cryptocurrency should be sent to.


A portmanteau of “alternative” and “coin”, altcoins refer to cryptocurrencies other than Bitcoin.

Electronic circuits that are specifically built for the single purpose of mining cryptocurrencies.


The process of verifying that someone or something is exactly who or what they claim to be.


The digital ledger that contains all records of the transactions that use a particular cryptocurrency.


The reward that users receive upon completing a task for a project or a given blockchain.

A currency with no intrinsic value and is not backed by physical goods, like paper bills.


A split in the blockchain network that happens when parties disagree on the network’s common rules and how the community should move forward. This often results in alternative chains.


Goods or commodities are said to be fungible when they are indistinguishable and completely interchangeable with other individual units that belong to the same category of items.


The fee paid when making a transaction on a blockchain. Faster transactions command higher gas fees, while slower transactions have lower fees.


The output of a hashing algorithm, hashes have a unique, fixed-length string. The implementation of hash functions prevents fraudulent transactions, double spending, and password storage.

Initial Coin Offering (ICO)

Non-Fungible Tokens (NFT)
A unique asset that is non-fungible or cannot be replaced with other units that are similar to it. Often in the form of digital artwork, NFTs are verified and stored using blockchain technology.

Open Source

Keeping records so that they remain transparent, public, and less likely to be tampered with.

Private Key

Also known as a secret key, this code is paired with a public key to decrypt the information that the said public key has hashed.


A consensus mechanism for blockchains that makes use of solving cryptographic puzzles to validate transactions and to generate new cryptocurrency tokens.


A consensus mechanism that depends on the user’s number of coins or tokens to mine or validate transactions.

Public Key

A set of alphanumeric characters that turns plaintext into cipher text. It is paired with a private key to decrypt the information it has obscured.
