CRYPTO GLOSSARY - ONLINE EDUCATION PLATFORM

Crypto Glossary is an educational platform where you can find commonly used
terminology, slangs, memes, specific names and everything that might occur in
your journey through crypto world.


ADDRESS

Address is a place where cryptocurrency can be sent to and from, in the form of
a string of letters and numbers. A cryptocurrency address can be shared publicly
in the form of text or QR code to those who want to send you cryptocurrency.


AIRDROP

Airdrop is a marketing campaign that distributes a specific cryptocurrency or
token to an audience. It is usually initiated by the creator of a cryptocurrency
in order to encourage the use and build the popularity of the coin or token.
Most airdrop campaigns run with mechanics such as receiving coins or tokens in
exchange for simple tasks like sharing news, referring friends, or downloading
an app.


ALGORITHM

Algorithm is a process or set of rules to be followed in problem-solving or
calculation operations, usually by a computer, although humans tend to follow
steps algorithmically as well (let’s say doing math or following a recipe).


ALL TIME LOW (ATL)

An All-Time Low (ATL), or a record low is the lowest price yet since a financial
instrument was unveiled. All-time lows can be recorded per year, month, per
week, or day. For Bitcoin, ATLs usually follow bad news about the coin or waning
interest from holders and users.


ALPHA

A software development team often works to release its product in stages. A
common practice is to solicit input and advice from a community, such that
ideas, suggestions, and improvements can be shared and incorporated before a
final product is released to the general public.


ALTCOIN

Altcoin is the term given to describe alternative digital assets, such as a coin
or token that is not Bitcoin. This nomenclature comes from the idea that Bitcoin
is the original cryptocurrency and that all others are then considered
“alternate” or “alternative” coins.




AML

Anti-money laundering (AML) is a broad term for laws and regulations put in
place to prevent criminals from making money illegally or moving illicit funds.
While many illegal activities are targeted by AML laws, some of the most
important are tax evasion, public corruption, and market manipulation through
methods such as wash trading.


ANARCHO-CAPITALISM

A political philosophy and school of thought that believes in removing
centralized states in favor of self-ownership, private property and free
markets. Many of the early adopters of Bitcoin were proponents of
anarcho-capitalism, believing it would give power and control back to the
masses.


ANGEL INVESTOR

Angel Investor Also called a seed or private investor, angel investors actively
seek out opportunities to provide funding for entrepreneurs or start-up
companies. They are often individuals with high net worth who are seeking new
methods of expanding their wealth while simultaneously helping to launch an up
and coming venture.


API

API stands for Application Programming Interface. It is a set of routines,
protocols, and tools for building software applications. APIs specify how
software components should interact, such as what data to use and what actions
should be taken.


ARBITRAGE

A practice of taking advantage of differences in price of the same commodity in
two or more markets or exchanges. For example, cryptocurrency prices on Korean
exchanges can be different from those on US exchanges. An arbitrage trader would
be in both markets in order to buy in one and sell in another for profit.


ASHDRAKED

A situation where you lose all your money, more specifically when you lose all
your money shorting Bitcoin. This was based on a story of a Romanian trader who
continued to short BTC when it went from $300 to $500, since he had made a lot
of profit doing so historically. Adapt your trading strategy!


ASIC

Short for ‘Application Specific Integrated Circuit’; it is a mining equipment
that is used specifically to mine a certain cryptocurrency. Often compared to
GPUs, ASICs are specially created and bought for mining purposes and offer
significant efficiency improvements and power savings due to its narrow use
case.


ASTROTURFING

A deceptive practice where a sponsor is masked or hidden, making it seem as
though a marketing message came from and is strongly supported by the community
when it is not.


ATH

The term “All-Time High” relates to the highest price that an asset has achieved
on an exchange, for the current trading pair that is being referenced. For
example, if a share of stock in XZY Corp comes to IPO at a price of $5 per
share, then trades as high as $20 per share, before falling to $10 in a certain
period of time, we could say that the “All-Time High” for the XZY Corp share
price was $20.


ATOMIC SWAP

Atomic swap is a technology based on smart contracts that enables the exchange
of different cryptocurrencies without the need for a centralized market or other
intermediaries. Also known as atomic cross-chain trading, atomic swaps involve
the trade of one cryptocurrency to another, even if they are running in
different blockchain networks.


ATTACK 51%

If more than half the computer power or mining hash rate on a network is run by
a single person or a single group of people, then a 51% attack is in operation.
This means that this entity has full control of the network and can negatively
affect a cryptocurrency by taking over mining operations, stopping or changing
transactions, and double-spending (reusing) coins.


ATTESTATION LEDGER

An attestation ledger is an account book designed to provide evidence of
individual transactions. It is generally used to “attest” that a financial
transaction took place, or to prove authenticity of transactions or products.


BAG

In the crypto space, the word bag refers to the coins, and tokens one is holding
as part of their portfolio. Typically, the term is used to describe a
significant amount of a particular cryptocurrency. There is no defined minimum,
but when the value is relatively high, one could say they are holding “heavy
bags” of a certain coin or token.


BAGHOLDER

A person who holds large quantities, or bags, of a cryptocurrency. Often used to
describe such a person when the price of that cryptocurrency is declining.


BEAR MARKET

The term bear market refers to a negative trend in the prices of a market. It is
widely used not only in the cryptocurrency space but also in the traditional
markets, such as stocks, bonds, real estate, and commodities markets.


BEAR TRAP

A technique played by a group of traders, aimed at manipulating the price of a
cryptocurrency. The bear trap is set by selling a large amount of the same
cryptocurrency at the same time, fooling the market into thinking there is an
upcoming price decline.


BITCOIN

Bitcoin is a digital form of money that runs on a distributed network of
computers "nodes". In a broader sense, though, many people often use the word
Bitcoin to refer to a few different things: a digital currency, a decentralized
public ledger, a protocol, or simply the big ecosystem that encompasses all of
these.


BITCOIN ATM "BTM"

A machine from which you can Buy or Sell Bitcoin and get Cash. Example: BTC to
USD, BTC to EUR, etc.

At the moment in the world are 7586+ active bitcoin ATM machine


BITCOIN HALVING

Bitcoin Halving is an event that occurs approximately every four years and
prevents coin inflation while halving the reward for miners for a mined block.


BITCOIN IMPROVEMENT PROPOSAL "BIP"

Bitcoin Improvement Proposal is A technical design document providing
information to the Bitcoin community, describing new proposed features,
processes or environments affecting the Bitcoin protocol. Suggested changes to
the protocol are submitted as a BIP. The BIP author is responsible for
soliciting feedback and consensus for his or her suggested improvements within
the community and documenting dissenting opinions.


BITLICENSE

A business license issued to cryptocurrency companies in New York, created and
provided by the New York State Department of Financial Services (NYSDFS).


BITS

Bits is a sub-unit of one bitcoin. Any form of money needs to be easily broken
down into sub-units to allow an equal exchange for goods or services. And
bitcoin is wonderfully divisible, with its smallest unit being the tiny
0.00000001 of a bitcoin – a unit known as a ‘satoshi’. There are 1,000,000 bits
in one bitcoin.


BLOCK

A container or collection of transactions occurring every time period on a
blockchain. In short, the term block refers to computer files that store
transaction data. These blocks are arranged in a linear sequence that forms an
endless chain of blocks - hence, the term blockchain.


BLOCK EXPLORER

An online tool to view all transactions that have taken place on the blockchain,
network hash rate, and transaction growth, among other useful information. In
short, a block explorer is a tool that provides detailed analytics about a
blockchain network since its first day at the genesis block. We can say a block
explorer acts as a search engine and browser where users can find information
about individual blocks, public addresses, and transactions associated with a
specific cryptocurrency.


BLOCK HEIGHT

The number of blocks preceding the block in question on the blockchain, or can
be thought of as total blocks in the chain before this point.


BLOCK REWARD

An incentive for a miner who successfully calculates a valid hash in a block
during mining. By contributing to the security and liveness of the chain, the
miner is rewarded with this incentive, ensuring that miners continue to act in
the best interest of the blockchain by legitimately taking part in the process
(instead of hacking it).


BLOCKCHAIN

A blockchain is a continuously growing, append-only, list of records called
blocks, which are linked and secured using cryptography.


BOLLINGER BAND

A tool developed by Bollinger to help in the recognition of systemic pattern
recognition in prices; it is a band that is plotted two standard deviations away
from the simple moving average, or exponential moving average in some cases.


BOTS

Automated trading software bots that execute trade orders extremely quickly,
based on a preset algorithm of buy-and-sell rules.


BRUTE FORCE ATTACK "BFA"

Brute Force Attack is a method of trial-and-error, in which automated software
generates and tries a large number of possible combinations in order to crack a
code or key.


BUBBLE

A bubble describes a situation where market participants drive prices up above
their value, which is usually followed by a steep, rapid drop in prices as the
market corrects.


BUG BOUNTY

A reward offered for finding vulnerabilities and issues in computer code. It is
often offered by cryptocurrency companies like protocols, exchanges and wallets
to identify potential security breaches or bugs before they are exploited by
unfriendly parties.


BULL MARKET

The term bull market refers to a positive trend in the prices of a market. It is
broadly used not only in the cryptocurrency space but also in the traditional
markets. In short, a bull market concerns to a strong market uptrend that
presents meaningful rising prices over a relatively short period of time. When
compared to traditional markets, cryptocurrency markets are smaller and
consequently more volatile. Therefore, it is quite common to see strong and
consistent bull runs, where a 40% price increase in 1 or 2 days is quite common.


BULL TRAP

A false market signal where the declining trend of an asset appears to be on the
upturn, but does not actually materialize, leading bulls to lose money after
going long.


BURNED

When a coin or token has been made permanently unspendable or unusable.


BUY THE F**** DIP - BTD / BTFD

Buy The F**** Dip an enthusiastic exclamation by supporters of a cryptocurrency
to buy while prices are at a low point.


BUY WALL

A situation where a large limit order has been placed to buy when a
cryptocurrency reaches a certain value. This can sometimes be used by traders to
create a certain impression in the market, preventing a cryptocurrency from
falling below that value, as demand will likely outstrip supply when the order
is executed.


BYZANTINE FAULT TOLERANCE "BFT"

Byzantine Fault Tolerance is a property of fault-tolerant distributed computing
systems, reaching consensus through a mechanism, where components may fail and
there may be imperfect information. For example, Bitcoin is Byzantine Fault
Tolerant, utilizing the Proof-of-Work system to reach a consensus on the
blockchain. Its applications are beyond blockchain, including messaging and
networking systems, among others.


BYZANTINE GENERALS PROBLEM

Byzantine Generals Problem is a situation where communication that requires
consensus on a single strategy from all members within a group or party cannot
be trusted or verified. An example of this agreement problem is where a group of
generals, encircled around a city, must decide whether to attack or retreat.
Every general must agree to attack or retreat, or everyone will be worse off.
Some generals may be treacherous, voting falsely, and messengers may deliver
false votes. Under these circumstances, a consensus must be reached. In
cryptocurrency, when network participants post false or inaccurate information
to others about transactions taking place, it could lead to network failure.


CANDLESTICKS

Candlesticks is a graphing technique used to show changes in price over time.
Each candle provides 4 points of information: opening price, closing price,
high, and low. Also known as “candles” for short.


CASH

in an organization or a network. When a system is centralized, it means that the
planning and decision-making mechanisms are concentrated at a particular point
within the system.


CHAIN SPLIT

Chain Split is another term used to describe Fork and is accordingly a situation
where a blockchain splits into two separate chains. Chain Splits generally
happen in the crypto world when new governance rules are built into the
blockchain’s code.

blockchain, at which point it has one confirmation. Each additional block is
another confirmation. Different exchanges require a different number of
confirmations to consider a cryptocurrency transaction final.


CONSENSUS

Consensus is achieved when all participants of the network agree on the order
and content of blocks and transactions contained in those blocks.

into two, resulting in one blockchain that follows the old protocol and the
other that follows the newest protocol. Some examples are Bitcoin and Bitcoin
Cash, or Ethereum and Ethereum Classic.


HASH

The act of performing a hash function on input data of arbitrary size, with an
output of fixed length that looks random and from which no data can be recovered
without a cipher. An important property of a hash is that the output of hashing
a particular document will always be the same when using the same algorithm.


HASH FUNCTION

adjusting their investment as a result.


HIERARCHICAL DETERMINISTIC WALLET (HD WALLET)

A wallet that uses Hierarchical Deterministic (HD) protocol to support the
generation of crypto-wallets from a single master seed using 12 mnemonic
phrases.


HODL

A type of passive investment strategy where you hold an investment for a long

WHAT IS BITCOIN?

Bitcoin is a digital currency that uses blockchain technology for secure,
decentralized, and transparent transactions. It was the first cryptocurrency and
remains the most well-known and widely-used.[1]


WHERE CAN I DISCUSS BITCOIN AND GET MORE INFORMATION?

The Bitcoin Forum (forum.bitcoin.com) is a popular online community where
Bitcoin enthusiasts can discuss topics like economics, mining, project
development, trading, and more. Other places to find information and discussions
include the Bitcoin subreddit and bitcointalk.org


HOW CAN I TRUST A BITCOIN SERVICE?

To determine the trustworthiness of a Bitcoin service, read reviews from other
users, research the service's reputation on sites like bittrust.org, and search
for the service on forums like the Bitcoin subreddit and bitcointalk.org.
Services that have been established for a longer time or are run by known people
in the Bitcoin community tend to be more trustworthy.


HOW POPULAR IS BITCOIN?

Bitcoin is the most well-known and widely-used cryptocurrency, but it is
difficult to determine its exact popularity. Cryptocurrency usage varies around
the world, and its popularity can fluctuate depending on market conditions and
public sentiment.


HOW DOES BITCOIN WORK?

Bitcoin transactions are recorded on a digital ledger called the blockchain.
Users send and receive bitcoins using digital wallets, and transactions are
verified by a network of computers (miners) that solve complex cryptographic
problems.
