ATH (All Time High)
The highest price that a cryptocurrency has been in history.
The lowest price that a cryptocurrency has been in history.
Short for alternative coins. Basically any crypto that isn’t Bitcoin (BTC)
‘Application Specific Integrated Circuit’ refers to mining equipment that is used specifically to mine a certain cryptocurrency. not all coins need ASIC’s to mine but bitcoin (and others) do, they can no longer be mined by computer CPU)
A person who has bough large quantities of a specific cryptocurrency. If the price of that coin then falls and the person is left holding the coin at a loss they are sometimes referred to as a bagholder.
Someone who is pessimistic about the state of the cryptocurrency market and prices and expects them to continue to decline. The term “bearish” reefers to someone who believes this.

Offline storage of cryptocurrency, this provides a means of safekeeping your crypto-currency by moving it offline. There are different ways this can be achieved but a paper wallet would be an example of cold storage.
Decentralisation refers to a system or network in which nodes or actors work together in a distributed fashion to achieve a global goal. The nodes are not owned or controlled by a single company or enterprise in a decentralised network
DEX (Decentralized Exchange)
A cyrptocurrency exchange that allows users to buy and sell cryptocurrency and other assets without a central intermediary involved.

The genesis block is the first ever block created on a blockchain.
When a block is broadcasted to the blockchain, it references the previous block. However, in the case of the genesis block, there is no previous block to reference, instead, it is hard coded into the software.
A unit of measurement for the amount of computing power a miner is capable of (usually measured in kH/s, MH/s, GH/s, TH/s, PH/s or EH/s) This is how many individual hashes per second are produced computed.
The term first became famous due to a typo made in a bitcoin forum, and the term is now commonly expanded to stand for “Hold On for Dear Life”.
The term suggests a person is not intending to use, spend, or trade their cryptocurrency. Instead they intend to save it for longer term investment.
You might also hear the terms Hodl’er and Hodl’ing.
ICO (Initial Coin Offering)
A type of crowd sale using cryptocurrency as a means of raising capital in the early-stages of a project. ICO’s offer early investors the opportunity to pick up new projects coins cheap in they hope the price will rise when the project gets listed on exchanges. However, ICO’s have been criticized due to the lack of regulation and the occurrence of scams and market manipulators. A lot of ICO projects never made it onto exchanges.
IEO (An Initial Exchange Offering)
A fundraising event that is administered by an exchange.
In contrast to an ICO where the project team themselves conduct the fundraising, an IEO will conduct fundraising on exchange platforms. This gives more legitimacy as the exchange has hopefully ran some back-ground checks on the project as they will have their own reputation to protect.

The process refers to a project’s or financial institution’s obligations to verify the identity of a customer in line with global anti-money laundering laws.
Literally short for Lamborghini (car brand). People often use this to express excitement over getting rich from cryptocurrencies. You may hear phrases like “when Lambo” or “Lambo soon”.
An independent blockchain running its own network with its own technology and coin/token. It is a production blockchain rather than a testnet.
Servers maintained by their owners, somewhat like full nodes, but with additional functionalities such as anonymizing transactions, clearing transactions, and participating in governance and voting.
The Mempool is a “waiting area” for transactions that each full node maintains for itself. After a transaction is verified by a node, it waits inside the Mempool until it’s picked up by a Bitcoin miner and inserted into a block.
A tree structure in cryptography where every leaf node is labelled with the hash of a data block. Every non-leaf node is labelled with the cryptographic hash of the labels of its child nodes. Hash trees allow efficient and secure verification of the contents of blockchains, as each change propagates upwards so verification can be done by simply looking at the top hash.
The process in which Proof of work is used to create new blocks are add them to a blockchain. It is also the process through which new bitcoins created.
A list of words used in sequence to access or restore cryptocurrency wallets. This must be kept secret from everyone.
The word moon is used to describe the price of a cryptocurrency going very high. You might here questions in the community like “When moon?”
Short for multi-signature address. This provide additional security by requiring more than one key to authorize a transaction.
A computer which is participating in the bitcoin network and has a copy of the ledge stored in its memory. Full nodes connect to other nodes to provide a fully decentralised network.
Someone who has no cryptocurrency and generally believes that cryptocurrency will fail.
Open-source software is a type of software in which the copyright holder or developer grants users the rights to study, change, and distribute the software to anyone and for any purpose. It encourages the free and open sharing of information in pursuit of the greater common good.
A valid block on the blockchain that is not part of the main chain. They may come into existence when two miners produce blocks at almost the same time, or they can be caused by an attacker attempting to reverse transactions. Transactions in orphaned blocks will go back into the mempool once the longer leg of the blockchain is decided.
OTC (Over The Counter)
Over The Counter transactions are made outside of exchanges, often peer-to-peer through private trades, or ‘OTC desks’ which pair together buyers and sellers. In jurisdictions where exchanges are not allowed or where amounts traded will move the markets (very large orders), traders may choose the OTC route.
P2P (Peer to Peer)
This refers to the interactions between two parties without any intermediary. Participants of a P2P network or transaction deal directly with each other.
This is the cryptographic hash of a public key. They are addresses that can be published anywhere for you to receive payments.
A private key is a string of data generated in the asymmetric-key encryption process. This key allows access to the funds held by specific wallet. This acts as a kind of password that should be kept hidden from anyone but the owner of the address.
A consensus mechanism aiming to bootstrap one blockchain to another with increased energy efficiency, by verifying that a cost was incurred in burning coin by sending it to an un-spendable address
PoS (Proof of Stake)
A consensus algorithm that rewards earnings based on the number of coins you own or hold. The more coins you stake, the more you gain by mining with this protocol. When someone stakes their coins they are using them to help secure the network.
PoW (Proof of Work)
A consensus algorithm which involves solving computationally intensive puzzles to validate transactions and create new blocks. This consensus methods requires the consumption of resources, such as electricity. The more ‘work’ you do or the more computational power you provide to the network, the higher your chance of finding a block and receiving the block reward.
QR code stands for Quick Response code. They are machine-readable labels which could be compared to a bar-code you would find in a supermarket. These are commonly used in cryptocurrency wallets to share public payment addresses, but can contain other information like links to websites. Its recommended caution is used when scanning QR codes as they could contain links to harmful content.
