Top 10 Crypto Terms You Should Know

By Boris Dzhingarov

Navigating the crypto space may make you feel like everyone is speaking a foreign language; here are some essential terms you should familiarize yourself with.

A wallet is an identifier used for transactions on blockchain networks. They come in various forms and shapes; most frequently these wallets are made out of flexible flat sheet materials that can easily fold.

1. Cryptocurrency

Cryptocurrency is a digital money that uses cryptography for security. It exists independently from financial institutions and does not fall under government regulation.

Bitcoin is perhaps the best-known cryptocurrency, but there are others. Each one operates using blockchain technology and features unique characteristics.

Some products feature limited supply that creates demand and reinforces perceived worth, such as Bitcoins with their 21 million maximum supply limit.

Mining cryptocurrency requires extensive electricity usage, leading to concerns over environmental impacts and sustainability. Furthermore, its anonymity attracts criminals and terrorists for illicit uses such as ransomware attacks and money laundering activities. As a result, regulators have increased oversight in this industry. For example, SEC has cracked down on initial coin offerings (ICOs) while CFTC has increased oversight in this market.

2. Altcoins

As someone new to crypto, it may be challenging to distinguish one token from the next – even experienced investors can fall prey to semantic rabbit holes occasionally.

Altcoin (short for “alternative coin”) refers to any cryptocurrency other than Bitcoin and Ethereum, although many forks were originally the primary focus. More and more altcoins are being introduced all of the time as more forks come onto the scene.

Alternative coins (altcoins) can be divided into categories depending on their purpose and features, including stablecoins, payment tokens and utility tokens. Some stablecoins are pegged to fiat currencies in order to reduce volatility; however, they remain highly speculative with sudden price changes – so only invest what you can afford to lose!

3. Bull Market

A bull market refers to periods in which stock prices experience significant gains accompanied by positive investor sentiment and rising economic activity and profits for companies. Investors may become increasingly confident, taking more risky investments with the expectation of greater returns – creating what’s known as “bull traps,” where investors pursue stocks based on optimism rather than considering their financial viability.

There’s no simple definition for what constitutes a bull or bear market, but they tend to occur alongside economic expansion and contraction. Bull markets usually occur when gross domestic product (GDP) increases while unemployment decreases; investor confidence also tends to surge at these times leading to greater stock buying activity and even initial public offering activity increases.

5. Forks

A fork is the permanent divergence from an original version of a blockchain, creating two independent currencies that can be traded. When updates change the rules for cryptocurrency trading, users have two choices when faced with an upgrade: follow one path or remain with their old version of the blockchain.

Cryptocurrency forks are created when people perceive they offer a better solution to an existing issue, or serve a different function than the original coin. They may also arise when updating software is taking place – this form of change is known as Bitcoin Improvement Proposals or BIP’s.

6. Faucets

Faucets are websites and applications that reward users with small amounts of cryptocurrencies (often Bitcoin) for performing simple tasks such as clicking links, viewing advertisements, or solving captchas. Once completed, these rewards are then automatically transferred into their crypto wallet. Originally introduced by senior Bitcoin developer Gavin Andresen as a way to promote and increase interest in this form of currency without risking their own capital investment, faucets provide free bitcoins without risking anything of their own money in return.

Most faucet manufacturers employ hot forging, a process in which heated metal is forced through a die that approximates the body of a faucet to create near net shapes with very little waste metal; minimal machining may be required before final assembly takes place – either manually or via rotary assembly machines depending on the manufacturer.

7. Legal Tender

Legal tender is defined as any currency declared acceptable for use in public or private debt settlement, contract fulfillment and legal fines and damages payments. Legal tender is an example of fiat money; it serves the same economic functions that precious-metal coins or paper money do without being backed by any material asset.

Legal tender is defined differently across nations, though it typically refers to paper currency and coins recognized for debt repayment or taxes owed. In the US, for instance, only Federal Reserve notes and coins issued through circulation serve as legal tender – checks or credit card swipes do not serve as such legal tender but do not correspond with physical currencies in any way.

8. Layer 1 & Layer 2 Solutions

Layer 1 & Layer 2 solutions refer to tools designed to increase the speed and scalability of a base-layer blockchain, such as state channels like Lightning Network or sidechains that extend its functionality while not making fundamental changes to it. Some examples of such solutions are Lightning Network state channels or sidechains used with nested blockchains.

Bitcoin and Ethereum blockchains utilize a proof-of-work consensus model in which miners solve cryptographic puzzles to verify new blocks, leading to slower confirmation times and higher transaction fees than before. Scalability requirements have become increasingly challenging to meet for these networks; solutions such as Sharding and Lightning Network may provide relief while zero-knowledge rollups or optimistic rollups could work to enhance performance without increasing block sizes (referred to as “scalability engines”).

9. Nonce

A nonce is an arbitrary number used only once during cryptographic communications, typically as part of an authentication protocol to protect older communications from being replayed (replay attacks). Nonces can also serve as initialization vectors in data encryption and help avoid repetitive sequences in encrypted text; they’re used to create and verify digital signatures as well.

Mining the Bitcoin blockchain involves finding valid nonces to earn their rewards when adding new blocks to the chain. The first miner to locate one that meets block hash requirements will receive Bitcoins as payment for their efforts.

Nonces are time-varying values with an acceptable probability of repeating, such as timestamps or sequence numbers or random generated numbers, to enable hash functions to generate unique outputs without being discovered through reverse engineering.

10. Multi-chain

Multi-chains represent the next evolution in blockchain technology that makes its implementation simpler for banks and businesses alike. By connecting multiple blockchains together via interoperability standards, multi-chains create an interconnected ecosystem between various ecosystems.

Multichains offer an array of interoperability features, such as atomic exchange, public and private data storage, decentralized consensus permissions management, etc. They utilize Solidity, a statically typed blockchain programming language designed to facilitate self-regulating business logic within smart contracts while leaving an irrefutable record of transactions.

Multichain uses a hybrid chain architecture that enables data to be stored both on- and off-chain while adding an extra layer of security, making it perfect for time stamping, identity and key-value databases. Miners are identified through an identifiable group and an acceptable mining diversity criterion between 0-1 ensures multi-chain is immune from spamming or centralization.
