Cryptocurrency Technical and Slang Terms


Used to receive and transactions on a blockchain network. It contains a string of alphanumeric characters, but can also be represented as a scannable QR code. Anyone can send a transaction to that address, but only the address’ true owner (owner of the corresponding private key) can access these funds or messages.

A slang term for “address”, as in a crypto wallet’s address.


Airdrops are a method of token distribution. Developers will send tokens to a blockchain address in exchange for a task, or even for free, to help decentralize the ownership of their tokens.

Bitcoin Maximalist

People that believe Bitcoin is the only cryptocurrency that is needed and that all other cryptos are inferior.


A trader that holds positive sentiment about the market and expects it to rise.

A bull


The process that a decentralized network goes through when agreeing upon the validity of transactions and when deciding which transactions should be included in a block.


Mathematics creates codes and ciphers in order to conceal information. Cryptography is used as the basis for the mathematical problems used to verify and secure transactions on the Blockchain.


The unauthorized use of someone’s computer to mine cryptocurrency.


The process of moving control of a system from one centralized location to many equal ones that can act on a peer-to-peer basis.

The denomination of ETH that gas is paid in. Each Gwei is 0.000000001 ETH.


A fixed-length string which can represent data of arbitrary size. A hash function converts any data (even images, videos, or an entire website) into an output like 0xdeadb33f and will produce the same output for any input. If the input is changed even slightly, the hash output will change as well.


The practice of amassing and keeping crypto. A typo for “hold” that has come to mean “Hold On for Dear Life”. It became a rallying cry when crypto was having more downs than ups and hold was misspelled in a popular form post.

The property that describes the fact that information added to the blockchain is final; it cannot be amended. Transactions are irreversible, only an opposite transaction can be executed.


Short for Lamborghini, when someone asks “When Lambo?” they are asking when a particular coin’s price will increase and they will profit enough to buy a Lamborghini.


The process of adding transactions to blocks and securing the blockchain. Miners are specialized hardware that race to solve equations and add the next block to the chain. The computer that wins receives the block reward for creating the newly added block.


The digital waiting room where transactions are sent before they are included in a block by a miner.


When a cryptocurrency rapidly increases in value, people will say “to the moon” or it’s “mooning” You will also hear the question “When Moon?” asking when will the price of a particular coin spike in value.

Private Key

A private key is a string of data that can digitally prove you have access to the crypto in a specific wallet. Private keys can be thought of as a password; they must never be revealed to anyone, as they allow you to spend the bitcoins from your bitcoin wallet through a cryptographic signature.


An alternative to the proof-of-work system, in which your existing stake in a cryptocurrency (the amount of that currency that you hold) is used to calculate the amount of that currency that you can mine. The higher your stake, the more likely you are to be selected as a validator and receive a block reward.


A system that ties mining capability to computational power. Blocks must be hashed, which is in itself an easy computational process, but an additional variable is added to the hashing process to make it more difficult. When a block is successfully hashed, the process must have taken some time and computational effort. Thus, a hashed block is considered proof of work.

Public Key

A cryptographic key that can be obtained and used by anyone to encrypt messages intended for a particular recipient, such that the encrypted messages can be deciphered only by using a second key that is known only to the recipient (the private key).


Short for wrecked - or what happens if you lose lots of money on a trade.

The smallest amount of bitcoin that can be sent. Named after Bitcoin’s anonymous creator that used the pseudonym Satoshi Nakamoto.

Seed Phrases
