Dusting Attack

Dusting Attack — the act of sending a small amount of cryptocurrency (referred to as "dust") to a user's cryptocurrency wallet with the aim of tracking its subsequent movement and eventually determining the owner's identity.



Emission (in the context of cryptocurrency) — the process of issuing new tokens and introducing them into circulation.


Ethereum — a blockchain platform for decentralized applications and the second-largest cryptocurrency by market capitalization.

Exchange Traded Fund (ETF)

Exchange Traded Fund (ETF) — is an exchange-traded fund that manages assets.



Fork (in the context of blockchain) — the process of making changes to the algorithms of a blockchain or creating a new cryptocurrency based on an existing one. Depending on the subsequent compatibility of updated and old nodes, forks are classified as soft forks and hard forks.



GameFi — is a concept that combines gaming and finance. It encompasses gaming projects created on the blockchain that enable users to monetize their in-game experiences.

Governance Tokens

Governance Tokens — are tokens that enable their holders to vote on key development matters within blockchain projects.



Halving — is the scheduled reduction of the reward for mining a block that occurs at regular intervals.


Hardfork — the implementation of significant changes that alter the fundamental rules of a blockchain. During a hardfork, the blockchain splits into two copies. Nodes that reject the update continue to operate with the old version, while participants who accept the changes begin to interact with the new version under the modified rules.


Hash (in the context of blockchain) — a unique digital fingerprint of a block computed based on the data it contains. Each subsequent block contains the hash of the previous one. Attempting to alter the data in a block will change its hash, breaking the linkage between blocks.



Know Your Customer (KYC) — the process of collecting users' personal data and verifying their identity.


Layer 1

Layer 1 — is the foundational blockchain network that processes transactions and records them on the main chain.

Layer 2

Layer 2 — is a protocol deployed on top of the base blockchain (Layer 1) to enhance its scalability.

Liquid Staking

Liquid Staking — is the issuance of tokens collateralized by cryptocurrency held in staking.



Metaverse — the concept of a next-generation internet space, comprising a virtual three-dimensional world that integrates various aspects of human life.


Mining — the process of cryptocurrency extraction using specialized computational hardware.

Mining Pools

Mining Pools — are a group of miners who combine their computational power for more efficient mining and consistent earnings.



Node — any user device connected to the blockchain network.

Non-fungible token (NFT)

Non-fungible token (NFT) — a type of token where each instance is unique and cannot be replaced with a similar token.


Peer-to-Peer (P2P)

Peer-to-Peer (P2P) — a network of devices based on the equality of participants. P2P also refers to a type of transactions in which funds are sent directly from one user to another without intermediaries.

Play to Earn (P2E)

Play to Earn (P2E) — is a category of games that includes projects that allow users to earn rewards with real value.

Private Key / Seed phrase

Private Key / Seed Phrase — a combination of 12 or 24 words. Knowing it grants full access to the wallet. Therefore, the secret phrase should not be shared with other users to prevent fund loss.

Proof-of-Authority (PoA)

Proof-of-Authority (PoA) — is a consensus algorithm that operates with a limited group of authoritative validators.

Public Key

Public Key — a wallet address, a kind of account number, open to all network users. It is used to receive cryptocurrency from other users, so it can be freely shared with others. Also, the public key can be used to track all wallet activity.

Staking — the temporary locking of coins in a wallet to earn the right to participate in maintaining the blockchain's functionality and receive rewards in the form of cryptocurrency. It is used in blockchains operating on Proof-of-Stake.



Token — a term that lacks a universally accepted definition and can refer to multiple categories of digital assets. According to one of the most popular views, a token is a digital asset that does not have its "own" blockchain and exists on another network. Additionally, a token can serve as a digital representation of another real-world asset, such as in the case of Sabai Property, which represents real estate.
