Cryptocurrency Alerting

Crypto Glossary

Beginner-friendly explanations for common terms used within the crypto ecosystem. This includes the blockchain, cryptography, investing and cultural memes.

51% Attack

A specific method of attacking a blockchain, where a single group of miners control more than 50% of the network. This allows a centralized party to control the "truth", effectively destroying its integrity.

Accredited Investor

Someone who has a net worth greater than $1,000,000 and meets certain additional income requirements. Qualifying individuals may file with the SEC to obtain this status. In the United States, only accredited investors may invest in hedge funds, venture capital funds, and other "advanced" forms of investing.


An event in which a blockchain project gives away ​tokens or​ ​coins for free. A simple condition may need to be met, such as having a certain existing balance in your wallet or registering before a deadline. Teams may elect to do this to raise awareness of a project, or ensure that a cryptocurrency is not consolidated among too few people.

Our platform provides free airdrop monitoring of any Ethereum wallet.

Air Gapped Device

A device that has never been (and will never be) connected to an unsecure network, such as the internet. This is a strategy to store cryptocurrency as safely as possible.

ASIC (Application Specific Integrated Circuit)

A computer that is specifically designed to mine cryptocurrency. The rise of ASICs has lead to more miner centralization since they make it harder to be profitable mining on a regular CPU or GPU.

Atomic Swap

The exchange of one cryptocurrency for another without the need for a trusted third party, such as an exchange. Atomic Swaps happens directly on the blockchain.

ATH (All Time High)

The highest price an asset has ever been sold for.


Shorthand for any cryptocurrency that isn't Bitcoin. For an overview of many different altcoins, view our Altcoin Explainer.

The opportunity to profit off of price differences of a given asset between different markets or exchanges.

Our platform can help detect arbitrage opportunities by using our "Any Exchange" price alert or percentage price alert.


Someone still holding an altcoin after a market crash.


Baking is the process that Tezos uses to append new blocks of transactions to its blockchain. It is a kind of delegated proof of stake. Bakers receive rewards for each block baked, similar to how Bitcoin miners receive rewards for discovering new blocks. A baker is more likely to bake a block if they have a larger number of rolls (groups of 10,000 XTZ). Accounts must be registered as a delegate in order to partake in the baking process, and can bake on behalf of other accounts who do not meet the 10,000 XTZ requirement.

Bear Market

A long-term downward trend in a market.

Bear Trap

A brief market recovery that gives the allusion of an upcoming bull market, but leads to further downward trends.

Buy Wall

A large buy order set at a specific price, likely to prevent lower buy orders from executing. This may be the result of Whales attempting to manipulate the price of an asset.


The thing being mined by miners. It's where transactions are stored. Once written, it cannot be altered or removed. It can be thought of like a page in a public ledger.

Block Lattice

A specific type of DAG (Directed Acyclic Graph) first introduced by the Nano cryptocurrency. Each account has one blockchain which is controlled by the account's private key, and each blockchain is replicated to all peers in the network. This arrangement is called a block lattice.

Block Size

The maximum amount of data that a single block can hold.


A decentralized database, often referred to as a public ledger. It's a chain of blocks, each of which record transaction data. New blocks are discovered by miners at a relatively fixed speed.

When the price of an asset exits a level of support or resistance, usually followed with increased volume. Our platform can help detect price breakouts by using our free percentage price alerts tool.

Burned Coin

Verifiably destroying a coin or token. This may be done for several reasons, such as rewarding existing stakeholders (reducing the supply tends to make the price go up), destroying unsold tokens from an ICO, or replacing them on an upgraded chain.

Byzantine Fault Tolerance

The characteristic of a system that is able to tolerate the issues brought up by the Byzantine Generals’ Problem.

Byzantine Generals’ Problem

A thought experiment that is intended to illustrate the difficulty of reaching consensus in a distributed system. In the problem, a group of generals who each command a portion of the army, surround a city. These generals must develop a plan to either attack or to retreat. Every general must reach a collective decision (if a unified decision is not reached, and some generals decide to attack, while others retreat, then the uncoordinated attack or retreat, the army will fail). Generals must coordinate via messengers (whom may lie) and generals themselves may be traitorous.

Circulating Supply

The number of coins or tokens that are circulating in the market and in the hands of the general public.


The first transaction in a new block which is used to reward the miners who discovered it. The popular cryptocurrency exchange,, is named after this term.

Our platform offers free Coinbase price alerts in addition to Coinbase exchange listing alerts.

Cold Storage

Keeping a cryptocurrency stored offline, as a security precaution to prevent theft.


A transaction is considered to be confirmed once it has been written to the blockchain. If a transaction has multiple confirmations, it means that additional blocks have been mined after the block that contains the transaction in question. The higher the confirmation number, the more certainty that a coin has not been double spent.

Our Wallet Watch service offers notifications when transactions have been confirmed on your wallet.

Consensus Mechanism

A consensus mechanism is the method that a blockchain uses to decide on the individual contributions of all its participants. Common examples are Proof of Work and Proof of Stake.


A time-limited event where people can purchase tokens of a cryptocurrency.


A blockchain-based virtual game that allows players to purchase, collect, breed and sell various types of virtual cats. It famously clogged the Ethereum network at the height of its popularity. A single a CryptoKitty has been sold for over $100,000.

Dark Web

The portion of the internet only accessible through specialized networks such as Tor.

DDoS (Distributed Denial of Service)

A common way to attack a network or website in order to render it unusable for a period of time. The attacker, often in control of a botnet, will overload the target by sending it more data than it can handle.

Dead Cat Bounce

A small price recovery after a large crash, giving an indication of false hope for an ultimately dead asset. Comes from the phrase, "Even a dead cat bounces once."

DPoS (Delegated Proof of Stake)

Invented by Daniel Larimer, it is an alternative consensus mechanism to Proof of Work. A cryptocurrency that uses DPoS votes for a "witnesses" to secure their computer network. Coin holders vote for "delegates", who are then responsible for validating transactions and maintaining the blockchain. It's used as a consensus mechanism in various cryptocurrencies such as BitShares, Lisk, EOS, Tezos, Ark, Nano and Cardano.

DeFi (Decentralized Finance)

Typically thought of in association with Ethereum, decentralized finance involves conventional financial tools built on a blockchain. This includes things like stablecoins, lending protocols, prediction markets, security tokens, derivatives and decentralized exchanges.

DEX (Decentralized Exchange)

An exchange that does not rely on a third party to hold the customer's funds. Trades occur directly on the blockchain using an automated process such as a series of smart contracts.

Fundamental Analysis (FA)

A methodology of analyzing a potential intrinsic value of an asset based on both qualitative and quantitative factors such as economic metrics, competition and their product.


An asset where each unit is essentially identical and interchangeable with one another.


The internal pricing for running a transaction or contract on Ethereum.

Governance refers to the method by which a cryptocurrency evolves over time. Certain coins have explicit "on-chain governance", which outlines a specific process by which proposed changes are voted on.

GPU (Graphics Processing Unit)

A computer optimized for computing visual display information. It typically has a highly parallel architecture and excels at math-heavy calculations (and therefore, much better at mining cryptocurrencies than a regular CPU).

Hal Finney

The first person to receive a Bitcoin transaction from Satoshi Nakamoto. Many believe he is actually Satoshi himself.

Hard Fork

A change in a blockchain protocol that is not backwards-compatible and requires all members involved to upgrade their software.

Any mathematical function that can be used to map data of arbitrary size to data of fixed size. In crypto, it is a one-way function that cannot be reverted. It's the kind of mathematical work used to mine cryptocurrencies.

Hash Rate

The speed at which mining is occurring.


A patented (closed source) "next-generation" consensus protocol that could theoretically render the blockchain obsolete. It features a "gossip protocol" where every node can spread signed information (events) on new and received transactions to randomly chosen neighbors. Neighbors will then aggregate received events with information from other nodes into a new event, and then send it on to other randomly chosen neighbors. This system can reportedly achieve an astonishing quarter-million transactions per second.

Ichimoku Cloud

Margin Trading

The act of using borrowed funds from a financial institution to trade in a leveraged manner.

Market Cap

The price of a coin multiplied by the circulating supply of that coin.


A full node or wallet that keeps the complete copy of the blockchain, but also performs additional functionality that is specific to a given cryptocurrency (such as participating in governance, or facilitating instant transactions). Someone who runs a masternode typically needs to own a certain amount of tokens to qualify, and may in turn earn passive income from it.

Max Supply

The maximum amount of coins or tokens that will ever exist in the lifetime of a given cryptocurrency.

Mempool (Memory Pool)

The mempool is where pending Bitcoin transactions wait for their chance to be written to the blockchain. A mempool is hosted by a node. The order by which transactions are selected from the mempool is based on the transaction fee paid to the miners.

Our platform supports free Bitcoin mempool size alerts to help monitor sudden changes in the network.

Merkle Tree

An important data structure commonly used within blockchains (as well as BitTorrent and Git). It allows for fast and secure verification of the contents of large data structures. Is used to test whether a transaction is included in a set or not.

A soft fork activated because miners signaled (voted) for it.


The process by which new blocks are created on a blockchain and transactions are verified.

Mining Algorithm

The nature of the computational work that must be performed by a miner in order to discover the next block on a blockchain. This is only applicable in Proof of Work style blockchains.

Mining Pool

A group of miners who share their processing power over a network. Each member is rewarded based on the amount of work they contributed to the block they helped mine.


Also called "tumbling", it is the randomizing of pool of cryptocurrencies in order to obscure the original source of funds.

Mt. Gox

A Bitcoin exchange based in Japan which got hacked and went bankrupt in February 2014. The original name is short for "Magic: The Gathering Online Exchange", which is what the site was originally intended for. It later became the first widely popular crypto exchange. It was founded by Jed McCaleb.

Multisig (Multisignature) Wallet

A wallet that requires more than one key to authorize a transaction.

Nick Szabo

Inventor of smart contracts, and designer of a precursor to Bitcoin called "Bit Gold".


A computer connected to a given blockchain network. This is where transactions are initially broadcast, before they are written to the blockchain itself.

Price Rally

An increase in the price of an asset over a sustained length of time.

Private Key

A a string of letters and numbers that serves as a cryptographic key allowing a transaction to be sent over the blockchain. This is essentially your password for a wallet address, and should be held as securely as possible.

PoI (Proof of Importance)

A blockchain consensus algorithm first introduced by NEM. Proof of Importance is the mechanism that is used to determine which nodes are eligible to add a block to the blockchain (this process is known as "harvesting" in NEM). It is different than Proof of Stake in that it factors one’s overall support of the network into account, not just the current moment in time. Vesting, transaction partners, number and size of transactions are all factors.

PoS (Proof of Stake)

The ability to mine cryptocurrency by simply holding coins in a wallet that is connected to the network. The more coins in the wallet, the more mining power.

PoW (Proof of Work)

A piece of data that is computationally difficult to produce but easy for others to verify. It is the primary thing that miners do to discover new blocks and contribute to the integrity of the network.

Public Key

The address used to send someone an amount of cryptocurrency. If a private key is your password, a public key is your username.

Pump & Dump

A coordinated manipulation of the price of an asset. A whale or group of people all start buying a cryptocurrency causing the price to drastically increase very rapidly. This often causes wild speculation and others start buying it out of excitement. The original actors immediately sell everything they originally bought causing the price to come tumbling back down.

Recovery Phrase

Also known as a mnemonic seed, it is a list of words which store all the information needed to recover a private key.

Resistance Level

It is a price that a given asset typically has trouble reaching above. If it does reach above that level, it will likely climb even higher now that this level has been broken.


Getting "wrecked". Losing a lot of money on an investment.

Ring Signature

A technology used by Monero in order to obfuscate the input of a transaction. A message signed with a ring signature appears to be endorsed by any person within a certain group of people. It is computationally infeasible to determine which member of the group actually produced the signature.

ROI (Return on Investment)

The percentage gain/loss on an investment.

Ross Ulbricht

The creator of the Silk Road, currently serving a life sentence in jail. Known under the pseudonym "Dread Pirate Roberts".

RSI (Relative Strength Index)

satoshi (sats)

The smallest atomic unit that a Bitcoin can be divided into. 1 satoshi = 0.00000001 BTC

Satoshi Nakamoto

The name of the anonymous creator (or creators) of Bitcoin and the author of the original Bitcoin whitepaper.


Also called a shitcoin, this refers to a token that provides little or no value, and is simply propped up on hype and false promises.


A hash function used by certain cryptocurrencies (noteably Litecoin) as an alternative to SHA-256. It is more memory intensive, which means it is not well suited for ASIC hardware. This ensures that CPU and GPU remain viable methods to mine the coin.

SEC (Securities and Exchange Commission)

A US federal government agency responsible for protecting investors by regulating securities markets. The mission statement of the SEC is to "promote a market environment that is worthy of the public's trust".

STO (Security Token Offering)

Similar to an ICO, but the tokens issued offer more rights and may be backed by assets, profits, or revenue generated by companies. The idea is to give these tokens tangible value from day one, and reduce the component of hype and speculation.

Segwit (Segregated Witness)

An upgrade to the Bitcoin protocol where signature data is removed from transactions, allowing more transactions to fit in a single block, increasing the speed of the network.

Sell Wall

A large sell order set at a specific price, likely to prevent higher sell orders from executing. This may be the result of whales attempting to keep the price of an asset low.


Someone trying to spread hype about something by endorsing the product in public. Typically has negative associations.


A method of encryption. Stands for Secure Hash Algorithm. Is involved in the mining process for Bitcoin and other cryptocurrencies.


A method of scaling a blockchain (increasing how many transactions can be processed per second) by splitting up which miners are working on what at a given time.

Shielded Address

A kind of address used by ZCash that is highly private. They are not visible in the blockchain and offer strong privacy against transaction graph analysis. The value transferred is private if both the sender and receiver are shielded. Shielded addresses are not supported in every ZCash wallet.


A method of betting on an asset decreasing in value. When someone shorts an asset, the investor borrows that asset and immediately sell it, hoping to buy it back when it is cheaper.


The ability to transfer assets from one blockchain to a separate blockchain and then be moved back if needed. It's a way for multiple cryptocurrencies to interact with one another.


Information that allows someone to prove that they have a private key, without having to reveal the actual private key.

Silk Road

An online black market, popularized as a platform for selling illegal drugs. It was only accessible via TOR, and only accepted Bitcoin as payment, which were tumbled in order to increase anonymity. Created by Ross Ulbricht.

SIM Jacking

Also known as a SIM swap scam or SIM splitting, this is a method of hijacking someone else's phone number in order to gain access to other accounts tied to that person. The hacker does this by gaining basic information about the victim and then contacting their phone provider pretending to be them. It is advised to use an app such as Google Authenticator instead of a phone number for two-factor authentication (2FA).

Smart Contract

A programmable way of executing logic on the blockchain. In addition to exchanging money, smart contracts allow arbitrary assets to be exchanged while avoiding a middleman.

Soft Cap

The minimum amount of money raised in an ICO in order to consider it a success.

Soft Fork

A change in the protocol that is backward-compatible, and generally does not require users to upgrade their wallets or take any other action. See: Hard Fork.


A high level programming language for writing smart contracts on the Ethereum network.

Stable Coin

A cryptocurrency that is pegged to a specific value (usually a fiat currency) and is intended not to fluctuate in price.

Stealth Address

A way of sending cryptocurrency by giving additional privacy to the recipient. By using a stealth address, you ask payers to generate a unique address in such a way that you can deduce the corresponding private key. So although a single "stealth address" can be visible in public, the blockchain sees all incoming payments as going to separate addresses.

Store of Value

An asset that can be reliably saved, retrieved, exchanged and predictably useful. Anything that retains these qualities as time passes is a good store of value.

Support Level

A price that a given asset typically has trouble falling below. If it does fall below this level, it will likely fall much lower now that the support level was broken.

Technical Analysis (TA)

A methodology of valuing the price of an asset based on studying market data, such as patterns in price and volume.


A type of DAG (directed acyclic graph) used by IOTA. It's a network consisting of nodes that issue and validate transactions. A qualifying node must choose two other transactions to approve, ensure approved transactions are not conflicting, and solve a cryptographic puzzle. A "coordinator" is currently used as a centralized consensus mechanism to prevent attacks on the network, and is scheduled to be shut down once the network is stable enough.


An alternate blockchain meant for testing purposes. Coins on this chain have no value. See: Mainnet.


A cryptocurrency that relies on another cryptocurrency (such as Ethereum) in order to operate. A token does not have a blockchain of its own.

TGE (Token Generation Event)

Another way of describing an ICO (Initial Coin Offering).

Total Supply

The amount of coins in existence. This number subtracts any coins that have been burned.

TOR (The Onion Router)

Open-source software designed to protect a user from Internet surveillance by routing traffic across a randomized set of proxy servers.

Transaction Fee

An expense that must be paid to miners in order for a cryptocurrency to be sent to a different wallet. This fee can vary based on how congested the network is, among other things.

Trend Line

A line that can be drawn (either horizontal or diagonal) in which the value of a given asset or indicator can frequently bump into but not cross. If a trend line is crossed, a larger price movement often follows.


A system that minimizes the amount of trust required from any single person or entity in a system by distributing it among many agents within it.

Turing Complete

Turing completeness is a quality that a programming language possesses if it can be used to emulate a Turing Machine.

Turing Machine

A Turing machine is a system that can simulate any computer algorithm, regardless of its complexity.

Txid (Transaction Identifier)

A (mostly) unique identifier for a given transaction.

Unconfirmed Transaction

A transaction that has not yet been included on a block, so it is still in a pending state.

User Activated Soft Fork (UASF)

A change in the blockchain protocol enacted by a majority of full nodes (as opposed to miners).

Vanity Address

An address that you choose yourself, or at least partly. Different blockchains have different capabilities around this.

Weak Hands

People who panic sell when the price of an asset begins to plummet.


A very wealthy person who can single-handedly manipulate the price of an asset.


An informational document that outlines a proposed solution or methodology for a given organization. This has become the go-to way for ICOs to market their token.
