(Segregated witness) is a blockchain protocol modification that alters transaction data storage. It reduces blockchain space by separating signature and transaction data. This boosts network throughput and lowers costs.

Sell Wall

A sell wall is a huge number of bitcoin sell orders at a specified price on an exchange. Sell orders can block price increases until they are filled. Traders may utilize a sell wall to determine resistance levels.


Many blockchain networks secure transactions and add blocks using SHA-256. It generates a unique, fixed 256-bit hash value for supplied data. This prevents input data modification without affecting the hash value, preserving blockchain integrity.


Sharding increases transaction throughput and reduces transaction validation time and cost in various blockchain networks. It involves partitioning the network into shards that may separately conduct transactions. Sharding increases network capacity, making it more efficient and scalable.


Shills promote a coin or initiative to inflate its value. To sell the project, they may utilize deception or exaggeration. Shilling is unethical and even illegal.


A derogatory term for any crypto that is not Bitcoin. There are good altcoins and bad altcoins, but considering all altcoins as shit results in missing the good ones early on.


Sidechains are alternative blockchains that allow asset transfers between them. It improves scalability and primary blockchain transactions. Sidechains can test new protocols and apps before implementing them on the main blockchain.


Slippage refers to the difference between the expected price of a cryptocurrency trade and the actual price at which the trade is executed. This can occur due to market volatility, order book depth, and other factors that can affect the liquidity and execution speed of a particular cryptocurrency exchange.

Smart Contract

Smart contracts are self-executing contracts with buyer-seller agreements put into code. They run automatically on a blockchain network. Smart contracts enable intermediary-free, secure peer-to-peer transactions.


Ethereum smart contracts are written in Solidity. It creates complicated and secure contracts like JavaScript. Solidity code is compiled into EVM-executable bytecode.


Simplified payment verification is a lightweight blockchain node. Verify transactions without downloading the blockchain. SPV nodes download a small portion of the blockchain and use full nodes for more information. Mobile wallets use SPV nodes.

Stale Block

Stale blocks, often called orphan blocks, are mined blocks that are not in the longest chain. When two miners locate a block simultaneously, the blockchain temporarily forks. Stale blocks are legitimate but not part of the blockchain and don't secure the network.


Stablecoin is a type of cryptocurrency that is designed to maintain a stable value. Its value is typically pegged to an asset such as fiat currency, precious metals, or other cryptocurrencies. Stablecoins provide a way to avoid the volatility that is common in the cryptocurrency market.

Stop Loss

Stop loss limits trading losses. It includes selling cryptocurrencies at a set price. The order triggers and sells the cryptocurrency automatically if the market falls to the predetermined price level, reducing investor losses.

Soft Fork

A blockchain protocol "soft fork" is backwards compatible. Nodes without the new protocol can still validate transactions. Consensus rules or transaction formats can enable soft forks. Soft forks are less likely to split chains than hard forks.

Sybil Attack

An attacker uses numerous phony identities or nodes to manipulate a network in a sybil attack. By generating numerous nodes that collaborate to control a blockchain network, a Sybil attack can alter its consensus process. This might make the blockchain network vulnerable to further assaults.


Technical analysis uses statistical patterns and market data to anticipate cryptocurrency price changes. TA helps traders detect price chart patterns and trade entry and exit locations. Trading choices often employ TA.


Testnets are blockchain networks for testing new features and updates without compromising real assets or transactions. Testnets let developers test new features in a virtual environment. Before putting a new feature or upgrade on the main network, they are used to test its security and functionality.


Tokens symbolize cash, utilities, or firm shares. Tokens are safely and transparently traded and transferred on a blockchain network. Tokens can be used for payment, rewards, or access.

Trailing Stop

A trailing stop is a trading tool used to automatically adjust a stop-loss order as the price of an asset moves in a favorable direction. The trailing stop order can help traders lock in profits while minimizing potential losses by allowing the stop-loss order to move closer to the current market price as the price increases.

Transaction Fee

Miners charge "transaction fees" to execute and validate blockchain transactions. The charge encourages miners to include transactions in the next block and prioritize their processing. Congestion, transaction size, and priority affect transaction fees.


Unspent Transaction Output (UTXO) is a bitcoin unit that may be utilized in a new transaction. It is a public key or address-associated bitcoin amount. Bitcoin and other blockchain-based coins employ UTXO.


Validators are blockchain nodes that validate and add transactions. They agree on network state using consensus procedures. Validators must have a particular quantity of bitcoin or a good reputation in the community.


Volatility refers to the degree of price fluctuations over a given time period. It is a measure of the rate at which the price of an asset, such as a cryptocurrency, changes. High volatility can create opportunities for profit but also pose risks for investors.


A wallet is a digital tool that stores and manages cryptocurrencies. It's essentially a software program that enables users to send, receive, and manage their crypto assets securely. Wallets can come in various forms, such as desktop applications, mobile apps, and hardware devices.

Weighted Moving Average

A weighted moving average is a technical analysis tool that gives more weight to recent price data and less weight to older data. This can be achieved by assigning a weighting factor to each price data point, which reflects its relative importance in the moving average calculation. A weighted moving average can provide a more accurate representation of the asset's current price trend by giving more weight to recent price movements.


A "whale" is a bitcoin investor or trader. These buyers and sellers can move prices significantly. Whales help traders and analysts forecast market mood and trends.

White paper

White papers describe a blockchain project's technical features and goals. It generally details the technology, token economics, and project roadmap. White papers describe project principles and advantages to investors and users.

Zero-Knowledge Proofs

Zero-Knowledge Proofs (ZKPs) use cryptographic techniques to establish a statement's validity without exposing any other information. This technology improves privacy and security for identity verification, transactions, and data exchange. Cryptocurrency authentication and ownership are increasingly using zero-knowledge proofs.


And there you have it. We could go way more into detail as there are thousands of smaller terms, but there are the main crypto definitions you should know as an investor and enthusiast.
