Basic terms


Technology based on the idea of ​​decentralization of information. Imagine hosting or a digital register, whose sole vision is only to save new data and is scattered across all the computers on the web – thousands to millions, but the information on it is minimal – bytes, not KB or MB, to reach the maximum speed of transmission and reception. This basic information is associated with registering (who, where, what holds, and transfers between them) but will still be in all other directions – registering is only one use case.


A digital currency (or in other words – a code, an application, or a digital program) that uses Blockchain technology to register its information. In some cases, they have their Blockchain, and tokens are created on an already developed Blockchain that has the capabilities to deploy Smart Contracts.


A Cryptocurrency created by Smart Contract and has the ability for a specific function under conditions. I.e., if a user keeps ‘this’ in his portfolio wallet, do ‘that’ or on ‘this’ condition, do ‘that’ (just a simple sample of what those functionalities can be). Tokens can be used for transfers and any other type of logic to enable a kind of contract between different users without the intervention of external auditors.

Smart Contract

The essence of the digital token type, containing the powers of the corresponding currency and the interaction with it. They are published on Blockchain – the main one is Ethereum. Almost all other token-based Blockchains have the same options and functions as Ethereum – communicating with the Smart Contract and using its capabilities, conditions, and operations.

ERC-20 Token

The primary type of token standard on Ethereum. It is suitable for making tokens and currency types because there is no distinction for each Token, and it is the same as all the others of the same kind.

ERC-721 Token

An additional primary type of token standard on Ethereum. It’s allowing diversified or, in other words – allowing for different metadata in each Token separately, i.e., suitable for NFT projects because you can have tokens in the same collection but look completely different as a visualization.

NFT (Non-fungible Token)

Term for an ERC-721 type, mainly connected to collections, games, or metaverse. In other words – painting, music, documents for collections and artifacts, heroes, and personas for games and metaverses on the Blockchain. These tokens use the ERC-721’s ability to visualize pictures with unique content.


Mainly for Cryptocurrencies, but tokens can also be mined. This is the way to save and send logs with Blockchain information and be rewarded in the process. Two main types are distinctive: Proof of Work and Proof of Stake. For PoW, video cards are primarily used because of their ability to absorb large amounts of data and calculate them in parallel. With processors, the difference is that only one packet of data can enter, and you have to wait to be calculated to be able to continue with the next one. Mining happens primarily on video cards because no matter how fast a processor is, it is limited by the number of requests it can calculate. The video card is not, and the more RAM you have on the video card, the more data you will store and count, i.e., you will be able to mine more and more efficiently. For PoS, collateral of previously acquired Cryptocurrency or Token is locked for a specific time. That is the way to get the rewards there. All Crypto-Mining is going through a Crypto-Mining Pool.

Crypto-Mining Pool

A term to describe one, several, or thousands of competing computers for a reward in the mining process. The reality of Crypto-Mining is that only one user gets the dividend for the current register block. A register block is the one package of data saved onto the Blockchain. This one user is randomly selected, and many other users have competed for nothing. Nevertheless, it’s much easier and faster to get the reward if you race with others in a Crypto-Mining Pool. That is because all of you are calculating the same block.

PoW / Proof of Work

It’s work proven by the Crypto-Miners and parts or all of the Blockchain passed through their computers – sending permanent data packets over the Internet, processing by video card or processor, and back to Blockchain.

PoS / Proof of Stake

The technology for obtaining Cryptocurrency or Token through so-called – holding. The idea is that instead of using computer power to calculate Blockchain data and be randomly rewarded, the same thing can happen, but for those who hold the respective Cryptocurrency or Tokens. Lock them in for some time and benefit the same way everybody will be rewarded if they lock some tangible assets in banks. Cryptocurrency or Token must have been acquired in some way beforehand. This is usually done with ICO – Initial Coin Offering or Crowdfunding methods.


A minor Blockchain is like a separate object connecting to a major Blockchain. Example – Polygon is a side-chain of Ethereum. The idea is to do the data calculations elsewhere, which is not as congested as the leading Blockchain. In this case, Ethereum’s fees have skyrocketed due to congestion.

Layer Two

A secondary blockchain that is like a separate object using the base blockchain, only to stand on it as a base. It is usually a detailed and complex Smart Contract that mimics the functions of the primary Blockchain but makes it much more efficient. An example is Immutable X.

Market Cap

How much a Cryptocurrency or Token is valued. The formula is simple – the stock exchange price is multiplied by the number of such currencies or tokens created.

Crypto Wallet

The term for software or hardware with software that holds transaction logs + private key and can interact with Blockchain. In reality, no wallet keeps money but registers and the ability to do something with that wallet. The currencies themselves hold on to Blockchain, and the wallet only makes connections from Blockchain to the place with which it interacts. There are different options – hardware – USB flash drive with Digital Certificate, browser extension – for example – MetaMask or software for computer or device, example for Windows, Android, iOS.

ICO / Initial Coin Offering

A way for each organization to make an initial investment in their project and thus secure a future. In reality, this is one of the main ways used by scammers and people with paper hands to make another boom and a way to deceive people. Over 90% of ICO projects have closed the shutters and fled with millions without anyone being able to hold them accountable because we are still in the Wild West of Crypto. Almost all the ICOs are dead, but in their place appeared another big bubble with NFTs. The world has already begun to realize that those who do not have a genuine product, but only promise, will do nothing. Hopefully, the ICOs and NFTs will soon reach their real potential with regulated laws, and frauds and scams will become less likely.

DeFi / Decentralized Finance

Any organization with the financial part of Blockchain, i.e., has a token placed on exchanges or is tradable through some digital protocol. The idea is that it is like a separate financial organization globally, with well-defined pre-set plans for how the Cryptocurrency or Token will develop, how it will be distributed, what its future is, and is not attached to any government or banks. DeFi aims to be decentralized because it is controlled by all the people that hold the relevant Cryptocurrency or Token, and they govern it, and DeFi is its government and bank in that sense (or this is the leading case with DeFi that are DAOs).

Private Keys

This is the unique code to access the wallet. You never share that with anyone. You save them somewhere secretly, if possible offline – on a USB flash drive or a piece of paper, for example, and they are your backup if you ever forget your wallet password. Usually, a few words in English are written in a particular order for you to be able to memorize them. It is also a 256-bit number that is more difficult to understand and therefore has a representation with these words.

Public Keys

This is your wallet address. You share it with everyone when you want the money sent to you. For example, CryptoTeka’s official Ethereum wallet is: 0xbaa920Aa247c08354a4B4039EAbfBe654C39b8D0 – most of them (Crypto Wallet addresses in particular) are like that, but they have some differences. For example, all Ethereum addresses start with 0x. Others start with different numbers or symbols or a combination of both, but in general, they all have some kind of structure according to the currency and Blockchain they are on. Be careful when sending coins here and there – they always look at which network you send from and which network you want to send. They must always be the same because otherwise, there will be an irreversible loss of funds. Ethereum has its Blockchain, Binance has its own, and Bitcoin is separate. On Ethereum networks, you can have many different tokens in one wallet, as long as they are on the Ethereum network, while on the Bitcoin network, everything is a Bitcoin coin and the only thing you can keep in your wallet.

DAO / Decentralized Autonomous Organization

An organization with no centralized authority to say how and where the project will develop, but all decisions are made when different network shareholders make proposals. Other network shareholders either accept or reject submissions. In this way, everyone who has a part of this organization has the opportunity to be part of its ruling. Such an organization cannot be created as a decentralized in the beginning. First, it has to go through the phase of a ‘Centralized Organization’ to make a product that will be widely used, and then comes the ‘Decentralized Migration’ – the one that gives the shareholders to govern and vote.


A term used to transfer funds or tokens from one Blockchain to another. As we wrote above in Public Keys – Cryptocurrencies or Tokens cannot be sent from one network to another, and this is done with particular sites/tools called Bridges, allowing this transfer.

Some Cryptocurrencies and Tokens
