“This is just based on my own research, so do your DD before investing yourself.”
- Decentralized- a system that operates without the control of a central figure or authority, and replaces it with a distributed peer-to-peer network.
- Degen- initially short for “degenerate gambler.” While this still refers to individuals involved with risky bets, degen may also refer more broadly to anyone involved in crypto and financial spaces. Like with “ape,” this is generally a self-assigned term and does not carry a negative connotation.

In investing, this usually coincides with investors buying an asset after it has already seen a considerable increase in price, hoping to get in and out before a pullback occurs. This is known as “FOMOing in” or “aping in.”
- Fork- a change to a blockchain’s protocol. When these changes are minor, this results in a soft fork. When the changes are more fundamental, this may result in a hard fork, leading to the formation of a separate chain with different rules.
See also: hard-fork, soft-fork

“No, crypto is a ponzi-scheme that will crash any day now.”
“LOL okay HFSP.”
- HODL- an expression meaning “hold” and frequently taken to be an acronym for Hold On for Dear Life. This term actually began its life as a typo on an old Bitcointalk.org, where user GameKyuuby explained that he was “HODLING” his bitcoin as the price dropped. The misspelling quickly caught on and is still used today.
- Holding the bag- this is the unfortunate position you find yourself in when an asset you own quickly drops in value but you do not sell. You are thus left holding a bag of worthless coins or stocks. Those who end up in this position are referred to, unsurprisingly, as bagholders.
“I’m not holding the bag. I’m HODLING. The bull market isn’t over.”
- ICO- (Initial Coin Offering)- the selling of tokens to the public in order to raise capital for a crypto-based project . ICOs are a crowdfunding approach, similar to a traditional company’s IPO.
- IEO- (Initial Exchange Offering)- similar to an initial coin offering, or ICO, an initial exchange offering is a method of selling tokens to raise capital, but with increased regulation.

Other users can send digital assets to your wallet via your public key, but only you can access your wallet’s contents by using the corresponding private key.
See also: wallet address, private key
- Pump and dump- a scheme where a cryptocurrency or other asset is hyped up, leading many to buy into it, raising its price. Those who did the hyping then sell their holdings of the asset as the price rises for a short period of time. This then leads to a sharp selloff where anyone who did not sell suffers a loss.
See also: holding the bag, rekt, rug pull
- Rekt- as in “wrecked,” used to express that one has suffered a huge loss.
- Rug pull- a scam maneuver where a crypto project takes the funds that have been invested into its protocol and runs. An inside job pump-and-dump, if you will. A rug pull can also occur in assets with highly centralized ownership. If someone is able to sell a large portion of the circulating supply at once, this rapidly increases the supply, which can cause the price of the asset to plummet.
- Rollup- a scaling solution that aims to improve transaction throughput and decrease fees by batching multiple transactions off-chain and then submitting them to the main chain as a single transaction.
i.e. Optimism, ZK, Arbitrum
- Satoshis (Sats)- the smallest denomination of BTC, equal to 0.00000001 bitcoin. Satoshis are named after Bitcoin’s pseudonymous creator, Satoshi Nakamoto.
- Scalability- a protocol’s capacity to handle higher demand and increase transaction throughput as the network grows.

- SHA-256- SHA stands for Secure Hashing Algorithm, a set of cryptographic hashing functions designed by the NSA. Essentially, SHA-256 takes an input of data and generates a long sequence of letters and numbers, called a hash. This hash is then used as a secure placeholder for the data it represents.
See also: hashing
- Sharding- a method of separating a network’s nodes out into smaller groups in an attempt to increase scalability. These shards are then able to reach consensus on behalf of the entire network, removing the need for every node to process every transaction.
- Shill- the act of heavily promoting a cryptocurrency, stock, or other asset in an effort to increase adoption and, in turn, raise its price. This is usually done via spamming on social media, and generally carries a negative connotation. A person who performs the act of shilling may also be referred to as a shill.
“I’ve been shilling this new dog coin on Twitter all month, wen Lambo?!”
- Shitcoin- a cryptocurrency with weak fundamentals and little to no use case.
- Sidechain- a parallel blockchain used to offload transactions from the main chain in order to increase scalability or add other functionality. Sidechains are connected to their main chain, or parent chain, via a two-way link which allows data and assets to be seamlessly transferred.
i.e. Matic, Dai
- Slashing- the process of burning or redistributing a validator’s staked cryptocurrency as punishment for approving fraudulent charges or otherwise endangering the network.
- Slippage- the price of a cryptocurrency may change between the time an order is placed and the time that order is ultimately filled. Slippage is the difference between a cryptocurrency’s quoted price and the price that a trade actually executes at.
- Smart Contract- self-executing code deployed on a blockchain. Smart contracts allow transactions to be made without an intermediary figure and without the parties involved having to trust one another.
- Soft Fork- a backwards compatible update to a blockchain. Unlike a hard fork, these changes do not require the creation of a separate chain.
See also: fork, hard fork
- Solidity- the native programming language of Ethereum, mainly used to write smart contracts.

i.e. LINK, UNI, AAVE
- TPS- (Transactions per second)- the number of transactions that a blockchain can handle per second, used as a benchmark to measure its computational power.
- Transaction- data written to a blockchain. New transactions are verified by nodes on the network and then broadcasted to other nodes. Once enough nodes have verified the transaction, it is considered valid and added to a block.
- TVL- (Total Value Locked)- a measure of the assets locked into an dapp’s smart contract, usually expressed in USD.
- Txn Hash- short for transaction hash, or transaction ID. This is a unique identifier used to represent a specific transaction, written as a long string of letters and numbers. By pasting a txn hash into a block explorer like Etherscan, you can find the details of the transaction it represents.

- Vaporware- a product or project that is announced and marketed but never actually materializes.
- Wallet- a software application or hardware device used to store the private keys to blockchain assets and accounts. Unlike a traditional wallet, a blockchain wallet does not actually store the coins or tokens themselves. Instead, they store the private key that proves ownership of a given digital asset.
i.e. Metamask, Coinbase Wallet, Ledger, Trezor
- Wallet Address- also known as a public key, this is an alphanumeric code that serves as the address for a blockchain wallet, similar to a bank account number. Other users can send digital assets to your wallet via your public key, but only you can access your wallet’s contents by using the corresponding private key.
- Web1- the first iteration of the web, commonly referred to as the “read-only web.” Web1 was characterized by static websites that displayed information. There was little to no user interaction or user-generated content.
- Web2- starting in the 90s, the “read-write web” is characterized by user-generated content and improved user interfaces. This led to the creation of blogs and social media platforms, as well as sites like Wikipedia and YouTube. Web2 placed more emphasis on user experience and interoperability between different applications and websites, giving us the vast network of connected websites and resources that we are familiar with today.
- Web3- the next iteration of the web being ushered in as we speak, which leverages blockchain technology, open-source applications, and the decentralization of data and information. Web3 aims to remove control of the web from monopolistic tech companies, and return ownership of data and content to its users. Also referred to as the “read-write-trust web.”
- Wei- the smallest denomination of ether, named after cypherpunk and cryptocurrency pioneer, Wei Dai. 10^18 gwei = 1 ether.
- YOLO (You Only Live Once)- investing too much money into a single asset; making a generally risky bet.
