Cryptocurrency Glossary – 140+ Need-to-Know Words


The world of cryptocurrency is new to many and there are dozens of words that I’ve had to learn in my journey to the moon. Here is a list of every need-to-know term for you to invest with cryptocurrency.



51% Attack

  • A 51% attack occurs when more than half of the computing power (hash rate) is controlled by a single entity. This entity can be an individual or a united group of individuals and the control over the network can result in different ‘attacks’; such as:
    • Preventing transactions from getting confirmed which can stop all transactions between people outside of the group in control
    • Reversing transactions
      • This allows the attacker to spend coins more than once; “double-spending”
    • Prevent others from mining which creates a mining monopoly for the attacker to reap all mining rewards


  • It is very difficult, if not impossible, to change transactions that occurred before the attack.
  • An attack, in itself, would not cripple a coin; however, I would be surprised if people used a coin that has been attacked due to the risk of losing money directly from the attack or as a result of the plummeting value after the attack.
  • It is possible to execute a 51% attack with less than 50% of the computing power but it is much less likely
  • It sounds scary but it is just theoretical at this point due to the amount of resources and know-how to pull it off.
    • There are people who hack fiat currency bank accounts so the threat of this unlikely attack isn’t a reason to not get involved in the world-changing technology that is blockchain.
  • It can be avoided by using a proof of stake coin instead of a proof of work coin



  • An address is like your bank account number
    • You can receive, store or send cryptocurrency using your address
    • It is what you give to people for them to give you cryptocurrency
    • People cannot remove your crypto with just your address (also known as your public key)
    • How do you access your online bank account? Probably with a password…this is like your ‘private key’
      • Never give out your private key because anyone with that information can get access to your crypto
    • An address consists of a bunch of numbers and letters


  • A method of distributing cryptocurrency for free
    • This usually only happens early in a coin’s life so many people have an active interest in the success of the coin or token


  • A coin that isn’t Bitcoin or, rather, an alternative to Bitcoin
    • As of late July 2018 there are 1491 coins and tokens listed on
    • Many of these coins claim to have a unique advantage over other cryptocurrencies; such as, cheaper transaction fees, quicker processing time or the ability to use it as a building block for applications.
    • Examples include Ethereum, Litecoin and Reddcoin


  • Buying CoinX low on MarketA and then immediately selling CoinX on MarketB for a higher price.
    • In 2017, in the same moment on two different exchanges, Bitcoin’s price varied by over $1,000
      • This means someone could gain over $1,000 by just trading their Bitcoin to an exchange where it was valued higher which results in a no-risk gain for the trader if they had software with enough sophistication


  • Stands for Anti-Money Laundering
  • This exists to prevent money that came from criminal activity to be put into circulation in aim for criminals to be able to spend the tainted money


  • The number of Bitcoin in a transaction
  • One of three components of a Bitcoin transaction – see input and output



  • It stands for ‘Application Specific Integrated Circuit’
  • Essentially, it is something that is meant to do only one task – often related to mining
    • An ASIC might only operate with SHA-256 for Bitcoin’s blockchain or scrypt for Litecoin, for example
    • Because it is focused on one task, it can be much more efficient than many standard desktop or laptop computers
  • New coins are coming out with coding to prevent the use of ASICs


  • Stands for all-time-high
    • This occurs when a coin or token reaches a point of being more valuable than it has ever been in the past
    • These moments are usually followed by slight drops in value because it is a common time for investors to cash out




  • An investor becomes a bagholder when they purchase crypto at an all-time-high and the price drops resulting in them ‘holding the bag’ until they sell at a loss or sell when the crypto goes back up in price

Bear market/bearish

  • A description of when the price for a commodity is in a downward trend
    • An easy way to remember this is by noting that a bear attacks with downward swipes of the claws which relates to the downward trend of price


  • A beartrap is set when an investor sells a large portion of a commodity to make it appear like there is a bear market – the prices are plummeting. This causes other investors to sell in panic which results in a further drop in price only to have the ‘trapper’ buy a large portion of the same commodity at a lower price
    • Since the drop in price was not representative of the market demands, the price usually returns back to the original place and sometimes even higher


  • The first decentralized, open-source, peer-to-peer cryptocurrency
  • It uses blockchain technology for transparency and security
  • Created in 2009 by Satoshi Nakamoto
  • More information can be found in Bitcoin’s whitepaper


  • An accurate record keeping system that offers impressive security and transparency
    • Security comes from being decentralized which requires a hacker to gain control of the majority of a network instead of one central database.
      • Every node in a network has a copy of the ledger
    • Transparency comes from the ability for anyone to view the transactions within the blocks in a blockchain. No names are attached to crypto addresses on the blockchain so there can also be a sense of anonymity.
    • The use of cryptography (passwords for your addresses) allows the network to operate without a central entity
      • This is where ‘crypto’ comes from in cryptocurrency
    • There are many applications for this technology that will impact medical records, marketing tracking, online content ownership and more


  • Every block in a blockchain contains a group of transactions
    • Think of a block as a page in a record-keeping book
    • Blocks cannot be altered after being added to the blockchain

Block Height

  • Block height refers to the number of blocks after the first block (genesis block – block 0) in the blockchain

Block Reward

  • You can receive a block reward by solving mathematical equations (mining)
  • Mining is essentially verifying transactions to be added to a block in a blockchain

Bull market/bullish

  • A description of when the price for a commodity is in an upward trend
    • An easy way to remember this is by noting that a bull attacks with upward swipes of the horns which relates to the upward trend of price

Buy Wall

  • A large buy order placed by an investor with intent to create the urge for people to buy a certain coin which can increase the market price
  • This can be followed by the investor selling all of the coin that was bought at the low price for a profit




  • When a ledger, or record-keeping book, is maintained by a single entity
  • Is commonly used by banks to hold all the account information
  • A hacker only needs to gain control of a central server
  • Antithesis of decentralized

    • USB wallet
      • Storing the Keystore file on a USB stick
    • Hardware wallet
      • Storing the information on an encrypted (password protected) USB stick-type device


  • When a node verifies a transaction
  • Some transactions require verification from 30 different nodes to be completed


  • Consensus occurs when all participants of a network agree on the validity of a transaction
  • This ensures that the distributed ledgers are exact copies of each other


  • A general term for coins and tokens
    • Also known as digital currency
  • Cryptography is used to secure transactions and control the creation of additional coins/tokens
  • Banks aren’t required for transactions to take place and the nature of the transaction can allow for people to exchange currency directly with another person – even if they don’t trust each other
  • The decentralized nature of cryptocurrency allows it to be theoretically immune to government interference


  • The art of writing or solving codes
  • It can be used to protect data and to validate its authenticity




  • Stands for ‘distributed denial of service’
  • A DDoS attack overwhelms a website by directing a large amount of traffic to the site in aim to crash a website or system


  • Stands for decentralized application
  • Blockchain-based application that is decentralized
  • An example is the use of smart contracts with Ethereum
    • The smart contract is the application that runs on the Ethereum network
  • A praised feature of DApps are having proven 100% uptime


  • When a ledger, or record-keeping book, is maintained by having exact copies on several different nodes throughout the network – each node being updated with every transaction
  • Is one of the keystone features of cryptocurrency due to the added security and transparency
  • A hacker needs to gain control of all nodes to infiltrate a decentralized system
  • Antithesis of centralized


  • The process of issuing fees to accounts with unspent coins
    • Only applicable to some coins; not all
  • Fees can increase as time passes

Desktop Wallet

  • Also known as a software wallet
  • Requires the download of software onto your computer
  • Still considered ‘hot storage’ because they are connected to the Internet
  • More secure than web wallets that store your private key on the website’s server

Difficulty (Mining Difficulty)

  • The amount of computing power required to solve the mathematical equations (hash) of a block. This is what increases to counteract increasing amount of mining (network hashrate) in order to maintain Bitcoin’s 10 minute confirmation time and it re-adjusts every 2016 blocks.

Double Spending

  • When a cryptocurrency is used more than once
  • The mining process ensures that each transaction is confirmed to prevent double spending
  • This may occur if a 51% attack is successful


  • To sell a large amount of cryptocurrency
  • Results in the price going down
  • Part of the ‘pump and dump’ scheme


  • Stands for Do Your Own Research

  • A transaction that has yet to be validated by the network
  • Also known as an unconfirmed transaction

Although I have listed and defined over 140 cryptocurrency terms, there are many more less-common terms out there. Here are some terms that didn’t quite make the cut for this glossary:

  • Ashdraked
  • EVM
  • Frictionless
  • DAO
  • Kimoto gravity well
  • Lightning network
  • QR code
  • Quantitative easing

Did one of these terms catch your eye as something you’d like to know more about?

Perhaps I forgot a term all together or you have a better definition of one of the terms listed.

Please comment below with your thoughts and I will be sure to respond! Please include a definition if you suggest a term that you know which should be added.

Always happy to help,
