Blockchain/Web3-related terms
A
Account
An account consists of a unique identifier/address, a balance of tokens, and possibly some additional properties used in other parts of the blockchain application.
Account Abstraction
Account abstraction in blockchain refers to separating fund control from the execution of smart contracts. In other words, it allows smart contracts to manage funds without users having to transfer control of their assets to the contract. This concept is crucial in blockchain as it can significantly enhance user experience and security without requiring users to give up full access to their wallets.
Active Delegate
An active delegate can mostly be considered a forging delegate who can forge new blocks. Active delegates often participate in consensus protocols, where they validate transactions, propose blocks, and contribute to blockchain governance. Their actions directly impact the consensus mechanism by influencing how consensus is reached.
AirDrop
An AirDrop is the distribution of free tokens or cryptocurrencies to a large number of wallet addresses. Blockchain projects often use this distribution as a marketing or promotional strategy to increase awareness, reward existing users, or attract new users to their platform.
Artificial Intelligence
Artificial intelligence (AI) involves creating machines that think and act like humans, performing tasks considered “smart.” AI processes large amounts of data differently from humans and aims to recognize patterns, make decisions, and judge like humans. It encompasses applications that perform complex tasks previously requiring human input, such as online customer communication. Often used interchangeably with machine learning (ML) and deep learning, AI refers to systems that operate under varying conditions without significant human oversight. AI models have the ability to learn from experience to improve performance.
Automated Market Maker
An Automated Market Maker (AMM) is the most common decentralized exchange (DEX) type that uses a liquidity pool of tokens to set asset prices automatically. Instead of an order book that most centralized or traditional exchanges use, AMMs rely on a mathematical formula to balance the token ratios in the liquidity pool. For example, to exchange ETH for USDC, a user adds ETH to the pool and receives USDC in return, with the exact amount determined by the pool’s current ratio and formula. In this way, AMMs ensure constant liquidity and allow for seamless trading without the need to match buyers and sellers. While larger trades may experience some slippage due to their impact on the pool’s balance, AMMs have become a cornerstone of decentralized finance (DeFi), offering 24/7 trading of diverse tokens and democratizing access to financial markets.
B
Betanet
A temporary, public testing network. It serves as an intermediary step where users can test and identify potential issues before a mainnet launch.
BFT – Byzantine Fault Tolerance
In a system where components must agree to reach a consensus, Byzantine failures (usually caused by errors that are hard to detect) will prevent those components from reaching an agreement. A Byzantine Fault-Tolerant system ensures that measures are taken to manage such failures.
BIP – Bitcoin Improvement Proposal
A Bitcoin Improvement Proposal (BIP) can be defined as a standard for proposing changes to the Bitcoin protocol. For example, BIP39 is one of many BIPs. This particular proposal describes the implementation of mnemonic code or a mnemonic sentence and how to create a human-readable mnemonic sentence, including how to convert that mnemonic into a seed.
Bitcoin
Bitcoin is a digital currency designed to eliminate the need for central authorities like banks or governments. Instead, it leverages blockchain technology to facilitate peer-to-peer transactions on a decentralized network. Transactions are authenticated via Bitcoin’s proof-of-work (PoW) consensus mechanism, which rewards cryptocurrency miners for validating transactions.
Bitcoin Cash
Bitcoin Cash is a hard fork of the Bitcoin network, developed as an electronic cash payment system. Its cryptocurrency, Bitcoin Cash (BCH), was created to be more practical for everyday transactions than Bitcoin (BTC). The Bitcoin Cash protocol features a larger block size, facilitating its use as a payment system by offering lower transaction fees compared to Bitcoin.
Blockchain
A blockchain is a public ledger of transactions maintained and verified by a decentralized, peer-to-peer (P2P) network of computers using a consensus mechanism to confirm data. Each computer in the network keeps its own copy of the shared record, making it nearly impossible for a single computer to alter past transactions or for malicious actors to compromise the network. It can be considered a database that keeps a continuously growing list of records known as blocks. These blocks are cryptographically linked, and each block contains a cryptographic hash of the previous block, the transaction data, and a timestamp.
Blockchain Application
A blockchain application is any application that uses its own blockchain as a database layer. For example, it can be an application running on its own blockchain built with a software development kit (SDK).
Blockchain App
Short form of blockchain application.
Blockchain Tetralemma
The blockchain tetralemma is based on the blockchain trilemma, which consists of decentralization, security, and scalability. It includes these three aspects but adds a fourth, usually profitability. As with the trilemma, trying to optimize all four of these aspects simultaneously is challenging.
Blockchain Trilemma
The blockchain trilemma highlights the difficulty of simultaneously optimizing three crucial factors in blockchain technology: decentralization, security, and scalability. Achieving the highest levels in all three aspects simultaneously is a challenging task.
Block
Blocks are files on a blockchain where transaction data are permanently recorded. They contain recent transactions that the network still needs to validate. Once a block is validated, it is closed, and a new one is created for subsequent transactions. A unique number identifies each block, which contains encrypted information from previous blocks and new transactions. After the network has verified a block and its contents, new blocks can be generated.
Block Height
The number of blocks in the blockchain between the genesis block and the block of the specified block height.
Block Size
Blockchain network protocols consist of blocks of data organized in a continuously updating, chain-like structure—hence the term “blockchain.” Each block contains transactions processed on the network, with the size or time interval of these blocks determined by the governance of the specific blockchain.
BSC – Binance Smart Chain
BSC is a high-performance blockchain compatible with the Ethereum Virtual Machine (EVM) and equipped to support smart contracts.
C
Centralized Exchange
A Centralized Exchange (CEX) is an online platform that enables internet users to buy, sell, and swap crypto assets. CEXs are operated and owned by a single entity. They act as intermediaries between buyers and sellers and are bound to comply with the laws and regulations of the jurisdiction in which they operate. A CEX platform maintains an order book for buy and sell orders, where traders specify the amount and price of tokens/coins they wish to trade. It helps conduct these transactions by providing liquidity for the tokens/coins it supports on its platform.
Some examples of CEXs are Binance, Coinbase, Kraken, and HTX.
CDBC
A central bank digital currency (CBDC) is a digital representation of a country’s central bank money or fiat currency that is not backed by a physical commodity like gold or silver.
Coin
A coin is classed as a form of money and is native to its layer 1 blockchain. Its primary purpose is to act as a store of value and a medium of exchange, which can be equated to other forms of currency. Examples of coins are (BTC) Bitcoin, (ETH) Ethereum, and (LTC) Litecoin.
Coinbase Transaction
A generation transaction, commonly referred to as a coinbase transaction, is the initial transaction in a block on the Bitcoin blockchain. It specifies the recipient(s) of the block reward. Unlike standard transactions that include both input and output data, a generation transaction creates new bitcoin (BTC) directly from the protocol, so it does not need input data.
Cold Wallet
A cold wallet can be considered a digital safe for your cryptocurrency. It’s a type of wallet that is kept offline, making it highly secure against online threats; unlike a hot wallet, which is always connected to the internet for easy access, a cold wallet is disconnected, protecting your assets from hackers. It can be thought of as storing your valuables in a secure vault instead of carrying them around. Examples of cold wallets include hardware wallets like Ledger and Trezor and paper wallets, where private keys are printed on paper and stored safely.
Consensus Mechanism
A blockchain consensus mechanism refers to a protocol unanimously adopted by all nodes in a blockchain network to validate and incorporate new blocks into the blockchain. Different types of consensus mechanisms exist, such as PoW, PoS, and DPoS. The primary function of the consensus mechanism is to ensure all nodes within the network reach agreement on the order and validity of the transactions.
Cross Chain Communication
Cross-chain communication enables interaction and value exchange between different blockchain networks, such as token transfers and data sharing, making it crucial to blockchain interoperability. Advancements in blockchain technology are expected to improve, resulting in cross-chain communication, allowing seamless data exchange across hundreds or even thousands of networks in the future.
Crypto-off-Ramp
Crypto-off-ramps are services that enable cryptocurrencies or tokens to be converted back into fiat currency, facilitating the transition from digital assets to traditional financial institutions. Crypto off-ramps are required to convert digital asset holdings into fiat.

Decentralized/Decentralization
Decentralization is a core feature of blockchain technology, reducing or even eliminating intermediaries across industries. For instance, decentralized finance (DeFi) platforms bypass banks, allowing profits and governance to be shared with users and the community. A decentralized network also crowdsourced consensus, making it difficult for any single entity to control or censor data. However, many experts believe that greater decentralization can reduce network throughput.
Decentralized Artificial Intelligence
Decentralized Artificial Intelligence (DAI) can be described as artificial intelligence models trained and executed on decentralized networks that eliminate reliance on a single entity for control or data storage.
Decentralized Storage Network
A Decentralized Storage Network (DSN) offers users peer-to-peer (P2P) access to buy or rent data storage space. Clients use end-to-end encryption to securely transmit P2P files, which are protected by cryptographic proofs. Examples of decentralized storage networks include Sia, Filecoin, and Storj, which seek to mitigate the risks of data failures associated with centralized cloud storage providers. While many DSNs are built on blockchain technology, others may employ different decentralized network architectures.
Deep Learning
Deep learning (DL) is a subset of machine learning in which algorithms with multiple successive layers (known as neural networks) can extract features from the input data and make predictions like classic machine learning algorithms.
DeFi – Decentralized Finance
DeFi is a financial framework built on decentralized blockchain protocols. It enables peer-to-peer transactions without relying on traditional intermediaries such as banks or brokers. It employs smart contracts, granting users access to diverse financial products and services without a central authority.
Degen
A “Degen” is a slang term in the cryptocurrency community for traders who take high risks and speculate without doing thorough research or due diligence. These individuals often ignore important metrics, tokenomics, fundamental analysis, and technical analysis, instead making investment decisions based on superficial aspects like a token’s logo or a catchy slogan.
DeSoc – Decentralized Social Networks
Decentralized Social Networks (DeSoc) are social platforms built on decentralized technologies, including blockchain and other distributed ledger technologies. Unlike traditional social networks controlled by centralized entities, DeSoc platforms give users ownership and control over their data, content, and social connections. Examples of blockchain-based DeSoc platforms include Farcaster and Lens, while non-blockchain examples include Mastodon and BlueSky. These networks enhance privacy, security, and censorship resistance by distributing governance and eliminating single points of failure. Despite their benefits, such as user empowerment and new monetization models, DeSoc platforms face challenges in scaling, adoption, and providing a user experience comparable to traditional social media.
Devnet
A blockchain network for development purposes. For example, the Lisk software development kit (SDK) provides a dedicated genesis block and configurations to conveniently set up a local Devnet while developing a blockchain application.
DePIN – Decentralized Physical Infrastructure Network
DePIN is a concept whereby token rewards incentivize the creation and enhancement of physical infrastructure in the real world. The aim is to transition from a centralized to a decentralized model. Utilizing blockchain technology and token rewards establishes and upkeeps decentralized physical infrastructure, encompassing wireless networks, cloud services, and power grids.
DeSci – Decentralized Science

By decentralizing funding, data management, and peer review, DeSci overcomes the limitations of traditional scientific institutions. This approach fosters broader participation and interdisciplinary collaboration and ensures the integrity of research. DeSci is instrumental in translating scientific advancements into practical applications, particularly in areas like healthcare and biotechnology, contributing to innovation across various industries.
DEX – Decentralized Exchange
A Decentralized Exchange (DEX) is an online platform that enables users to buy cryptocurrencies directly through peer-to-peer transactions without any middleman. Examples include Binance, Coinbase, and Bitstamp. Unlike traditional centralized exchanges, where a third-party entity manages user funds and oversees transactions, a DEX operates on a peer-to-peer basis.
DLT – Distributed Ledger Technology
Distributed Ledger Technology (DLT) is a decentralized peer-to-peer digital system that records transactions simultaneously across multiple locations. Utilizing cryptography and consensus mechanisms, DLT enables participants to share an unalterable copy of the same ledger.
Blockchain is one of the four types of DLTs, whereby its transaction records are kept in the ledger as a chain of blocks.
Double Spending Problem
The double spending problem is a significant risk associated with digital currencies, where the same funds can potentially be duplicated and spent more than once. In contrast, with fiat currency, once the spender hands over physical cash, it cannot be used again. However, with digital currency, blockchain systems are specifically designed to prevent the same digital coin or token (e.g., Bitcoin) from being sent to multiple addresses. The risk of double spending in cryptocurrencies is reduced through various mechanisms ensuring all transactions’ authenticity.
DPoS – Delegated Proof of Stake
DPoS is the mechanism for determining eligible block creators. It is achieved by voting for registered delegate accounts, which can then create blocks depending on their vote weight. It is part of a blockchain’s consensus algorithm.
E
EIP
An EIP is a formal recommendation for updates and changes to the Ethereum network. The acronym EIP stands for “Ethereum Improvement Proposal,” the Ethereum community members use them to contribute to the Ethereum network’s further development.
EoT – Economy of Things
The Economy of Things goes beyond the Internet of Things by letting devices independently make money and trade the value they create. In contrast to the Internet of Things, where devices are contextually aware and linked, the Economy of Things turns devices into economic agents. It’s a system of decentralized and borderless economic connections between machines and people, allowing them to become increasingly autonomous and economically independent.
ERC
ERC is a technical standard used on the Ethereum blockchain for smart contracts. It stands for “Ethereum Request for Comment.” The ERC-20 standard was originally implemented in 2015, allowing developers to establish their own tokens by adhering to it.
ERC-20 Token
ERC-20 tokens are Ethereum-based tokens with standardized features. These ensure compatibility can be maintained with the broader blockchain ecosystem. Simply put, ERC-20 serves as the technical standard governing the implementation of tokens through smart contracts on the Ethereum blockchain.
ERC-721 Token
ERC-721 is a standard for non-fungible tokens (NFTs) representing unique ownership. It is more intricate than ERC-20, featuring optional extensions and distributed across multiple contracts.
Ethereum
Launched in 2015, Ethereum is a decentralized, blockchain-based platform designed as a global supercomputer to support a range of interoperable decentralized applications (dApps) using token economies and smart contracts. It operates on self-executing smart contracts that eliminate the need for intermediaries. The network is powered by its native cryptocurrency, ether (ETH), which covers transaction fees. Ethereum is open-source, programmable, private, and censorship-resistant, serving as the foundation for a decentralized internet that has led to innovations such as Initial Coin Offerings (ICOs), stablecoins, and decentralized finance (DeFi) applications.
EVM – Ethereum Virtual Machine
The EVM is a vital component of the Ethereum platform. It enables developers to build dApps and smart contracts. EVM is instrumental in powering most of the dApps built today. It also facilitates the execution of smart contracts and supports Ethereum’s goals of achieving user adoption and decentralization.
F
Faucet
In the blockchain world, a faucet is generally defined as a tool that allows users to receive a certain amount of tokens for free.
Fiat Currency
A fiat currency is a form of government-issued money used as legal tender by the citizens of a particular country, government, or region. Unlike currencies backed by physical commodities such as gold or silver, fiat currencies are backed by the issuing government. As a government-regulated instrument, fiat currency serves as a medium of exchange, a store of value, and a unit of account. For money to be considered fiat, it must be durable, portable, divisible, uniform, widely accepted, and have a limited supply. Most paper currencies, such as the euro, yen, and U.S. dollar, are examples of fiat currencies.
Forging
Forging is the process of creating new blocks on a blockchain. Rewards can be paid to the participants with cryptocurrencies and fees. Similar to mining in Bitcoin or Ethereum, forging validates transactions but operates differently in ecosystems like proof-of-work (PoW) and proof-of-stake (PoS). A more in-depth explanation of forging can be found here.
Fork
A fork can be defined as an occurrence of a blockchain diverging into two forward paths in the network. In other words, an alternative version of the blockchain is created by simultaneously generating two blocks on different parts of the network. See hard fork and soft fork.
Fungible Token
A fungible token is a digital asset created to have the same value and be interchangeable with other tokens of its kind. Fungibility is a key principle in traditional finance and economics, closely linked to government-issued money or fiat currency.
G
Gamification
Gamification involves adding fun and interactive gaming features to non-game situations to boost interest and encourage specific behaviors. Crypto platforms use game-like elements such as rewards, badges, or levels to motivate users to participate and actively explore different features. This creates a feeling of accomplishment and progress, ultimately increasing user engagement and building long-term loyalty.
Generative AI
Generative AI models can create new data like images, video, audio, or text. While not directly used in core blockchain functions, generative AI has the potential to create new user experiences within Web3 environments.
Genesis Block
The genesis block describes the very first block in the blockposchain. It defines the initial state of the blockchain at the start of the network. A genesis block must be given to the application, and all networks should have a different genesis block.
H
Hard Fork
A hard fork is a software update that lacks backward compatibility. A hard fork occurs when new rules are introduced into the blockchain code that is incompatible with the previous version’s rules. Nodes that don’t update their software become unable to communicate with those that have, sometimes leading to a split in the blockchain into two separate networks—one following the old rules and the other operating under the new, updated rules. For instance, Bitcoin Cash was created after a hard fork of the Bitcoin blockchain.
Hash
Hashing is the process of converting an input of any size into a fixed-size output using a mathematical function known as a hash function. These functions are considered one-way, meaning they cannot be reversed to retrieve the original input. Unlike encryption, which aims to conceal data in transit or at rest, hashing is mainly used to verify data authenticity. It also plays a crucial role in securing network components, such as passwords and sensitive information, by storing them as hashes—the outputs generated by hash functions.
Hot Wallet
A hot wallet is like a digital wallet for everyday spending—always connected to the internet for quick transactions, like buying something or sending money. This convenience comes with a higher risk of hacking, similar to the risk of carrying cash. While hot wallets are ideal for easy access and frequent use, they aren’t the best for storing large amounts of cryptocurrency long-term. For that, cold wallets kept offline and secure from online threats, are preferred.
I
Interoperability
Interoperability is like speaking multiple languages fluently, allowing different blockchain networks to communicate seamlessly. This means that smart contracts on different blockchains can interact with each other, and it is possible to transfer assets and data between blockchains without needing a central authority. It can be thought of as trading Bitcoin for Ethereum directly, such as swapping your dollars for euros without needing a bank. The key difference here is that it is possible to natively swap tokens across different blockchain networks without relying on a central entity.
IoT – Internet of Things
This is a collective network of connected devices and technology, enabling communication between the devices, both with the cloud and among themselves.
J
JavaScript
JavaScript (JS) is a popular programming language for creating complex features and web applications. It is also the official programming language used by Lisk.
K
KYC
Know Your Customer (KYC) is a regulatory compliance process that businesses use to verify the identity and assess the risk level of their customers. This typically involves users providing official identification, such as a passport or driver’s license. KYC regulations mandate that financial firms collect personal data on their customers and confirm the legitimacy of the individuals or clients they serve.
L
Layer 1
A layer 1 blockchain serves as the foundational blockchain upon which secondary blockchain networks and applications can be constructed. L1s offer the fundamental infrastructure and security necessary for the operation of layer 2 blockchains. Good examples of Layer 1 networks are Bitcoin, Ethereum, and Solana.
Layer 2
A Layer 2 network encompasses any off-chain network, system, or technology constructed on top of a layer 1 blockchain. This extends the capabilities of the underlying base layer network. Layer 2 networks can be employed to enhance blockchain functionalities and reduce the load on its parent network, enabling features like increased transaction throughputs. Examples of well-known layer 2 networks are Polygon, Arbitrum, and Lisk.
Layer 3
Layer 3, commonly known as the application layer, is built on top of layer 1 (the base blockchain) and layer 2 (scaling solutions). While layers 1 and 2 address infrastructure and scalability, layer 3 is dedicated to developing user-facing applications and protocols. This layer includes decentralized applications (dApps), decentralized finance (DeFi) platforms, and other blockchain-based services directly interacting with users.
Ledger
A ledger is a record-keeping system for tracking financial transactions. Blockchains are often referred to as distributed ledgers.
Lightning Network
The Lightning Network is a layer 2 scaling solution that operates on top of blockchains like Bitcoin. It establishes a private, two-way channel between users, allowing multiple transactions to occur off the main blockchain. These transactions are later consolidated and recorded as a single transaction on the main blockchain. This approach, applied across numerous transactions, reduces network congestion and enhances scalability.
LSK
The token used in the Lisk Mainnet.
M
Machine Learning (ML)
A core AI technique in which algorithms learn from data to make predictions or decisions without explicit programming.
Mainnet
A mainnet is a fully developed, functional, and independent blockchain that runs on its own network and uses its own protocol and technology.

A Merkle tree is a data structure made up of data-converting hashes used by blockchains to verify information securely. It summarizes all the transactions in a block by generating a digital fingerprint (i.e., a single hash) representing the entire set of transactions.
Metaverse
The metaverse is an immersive, multi-dimensional environment. It is a virtual reality world where people can interact with each other and digital objects as if they were in the same physical space. It represents a future iteration of the internet with persistent virtual worlds for socializing, working, gaming, and shopping, creating an evolved, three-dimensional cyberspace.
Mining Pool
A mining pool aggregates, or “pools,” the hash rate of participating crypto miners to collectively mine blocks and share the associated block rewards. This approach offers miners a more consistent return on their efforts and enables smaller operations to compete with larger mining farms. Mining pools are blockchain-specific and typically charge a fee of 0–2% of all block rewards.
Module Asset
A module asset allows a module to execute specific state changes on the blockchain based on transactions. A transaction with the corresponding module and asset ID needs to be sent to the blockchain application to trigger the logic defined in a particular module asset. The data provided in the transaction asset provides the required input data to execute the desired state changes.
Multi-Signature Wallet
A multi-signature (multi-sig) wallet is a type of wallet that requires multiple keys to sign a transaction before it can be executed. In contrast, standard wallets need only a single signature to authorize transactions.
N
Network Graph
A network graph (force-directed graph) is a mathematical structure used to represent relationships between points in an aesthetically pleasing manner visually. It illustrates how subjects are interconnected, with entities displayed as nodes and their relationships represented by lines.
Nonce
A nonce (short for “number only used once”) is a number added to the data in a block before it is hashed during the Proof of Work (PoW) mining process.
Natural Language Processing (NLP)
NLP enables AI to understand and generate human language. NLP can be used to analyze sentiment in social media data on blockchains or to create chatbots for interacting with decentralized applications (dApps).
Network Effects
Network effects happen when a product or service becomes more valuable as more people use it. This, in turn, increases the value of the service or product for the existing users, encouraging new users to join and increasing its value further in a positive feedback loop.
NFT – Non Fungible Token
NFTs are digital assets in the form of unique cryptographic tokens. Examples can represent real-world objects such as art, music, games, and videos, which, due to their uniqueness, can result in them becoming collectible items of value.
Node
A blockchain node is typically a device, such as a computer, that participates in a blockchain network by running the network’s protocol software. This enables it to validate transactions contribute to network security, and ensure consensus on a public ledger. Nodes communicate with each other, and a greater number of nodes increases the network’s decentralization.
O
Off Chain Assets
Off chain assets in crypto are tokens or coins that are stored off of the blockchain. For example, in a cold wallet or a third-party intermediary.
Optimism
Optimism is a Layer 2 scaling solution built on top of the Ethereum blockchain. It addresses the challenges faced by running on the Ethereum network. Optimism developed the OP Superchain, a network of interconnected layer 2 blockchain networks built using its open-source OP Stack, which was designed to provide enhanced scalability, interoperability, and flexibility for decentralized application development.
OP Chains
The Superchain is a network of layer 2 chains called OP (over powered) chains that share security, a communication layer, and an open-source technology stack. Unlike other multi-chain designs, these chains are standardized and intended to be used interchangeably.
Optimistic Rollups
Optimistic rollups accumulate transactions on the respective chain and bundle them into a batch (rollup). These are then submitted for execution on the mainchain. The term “optimistic” is used as these transactions are considered to be valid unless proven otherwise within a specified time period. This reduces the number of computations and results in lower gas fees. Furthermore, a “fraud-proof” mechanism is deployed.
Oracles
Oracles are third-party services that provide external real-world data to blockchain protocols, often to smart contracts. They enhance the blockchain’s functionality by securing, verifying, and validating its data, as blockchains and smart contracts are typically closed systems. Oracles can be either decentralized, drawing from multiple data sources, or centralized, controlled by a single entity. An essential use of blockchain oracles is delivering price and data feeds for the trustless execution of smart contracts in the DeFi sector.
Orphan Block
An orphan block (or stale block) is a block that gets rejected by the blockchain network due to the simultaneous mining of two blocks. Although theoretically, a soft fork occurs when two blocks are mined at the same time; orphaned blocks typically affect only a few subsequent blocks. These blocks are valid and verified but serve no purpose once rejected and exist in isolation from the main blockchain.
P
Passphrase
A passphrase can be described as an extended password. It is a string of words used for authentication, usually 15 characters or more.
Peg
Pegs are mechanisms that link the value of one asset to another on a 1:1 basis. They are mainly used to enable the trading of different assets, which is often limited due to varying blockchain protocols. Pegging allows users to exchange assets pegged at a 1:1 ratio with their native assets while potentially enjoying lower transaction fees and faster confirmation times.
PFP – Picture-for-Profile
A PFP NFT, which stands for Picture-for-Profile Non-Fungible Token, is a unique digital image created to be the owner’s personal profile picture.
POAP – Proof of Attendance Protocol
A Proof of Attendance Protocol refers to NFTs that prove a person has attended a particular event. These badges are supported by a cryptographic record and sent to a person’s wallet as a reward for participating in certain activities.
PoS – Proof of Stake
Proof of Stake (PoS) is a consensus mechanism used to achieve agreement over a distributed network. With PoS, the consensus is determined based on each user’s stake in the network.
In PoS networks, participants are incentivized to stake native coins in validator nodes, which involves validating transactions and earning rewards. By staking, users help secure and stabilize the network while earning interest on their investment. Validator nodes are randomly selected to validate block data and generate the next block, earning native coins as a reward. A strong network of nodes enhances security, resilience, and computational power. Additionally, PoS systems often allow validator nodes to participate in decentralized governance by voting on important updates and decisions. PoS networks already demonstrate faster speeds, greater scalability, and improved energy efficiency compared to Proof of Work (PoW) blockchains.
PoW – Proof of Work
Proof of Work is a type of consensus mechanism used to achieve agreement over a distributed network. With PoW, in order to complete the transactions on a given network, the miners have to solve complex mathematical problems to be rewarded with the tokens. In a nutshell, the PoW consensus algorithm is used to confirm transactions and produce new blocks to the chain. Miners have to compete against each other to complete transactions on the network and receive rewards. Hence, the PoW mechanism allows consensus to be reached while simultaneously maintaining network security.
Private Key
Public-key cryptography (asymmetric cryptography) is a specialized cryptographic system that uses pairs of long alphanumeric keys that must be used together. Public keys serve as wallet addresses that can be shared with others, while private keys, known only to their owner, provide access to funds. These keys are generated through cryptographic algorithms that solve mathematical problems to create a one-way function.
Protocol
A blockchain protocol refers to a specific blockchain platform or network, such as the bitcoin protocol. It can also denote a set of rules that govern interactions within a blockchain network, including consensus, network participation, and transaction validation.
Protocol Layer
The protocol layer comprises the core blockchain consensus mechanism and nodes that form the foundation of a blockchain. It can also include external layer 2 systems like sidechains and virtual machines. Typically, this layer refers to the underlying architecture of all layer 1 blockchain networks. It contains elements such as node addresses, error reporting, interface identification, network synchronization, state changes, and the processing of network transactions.
Public Address
A public address is an abbreviated form of a user’s public cryptographic key. It is used to receive transactions via a blockchain network protocol and often serves as a substitute for a public key.
Public Key
A public key is a cryptographic code that allows you to receive cryptocurrency transactions. Paired with a private key, it can be shared publicly, enabling others to send transactions. However, the private key is required to “unlock” and prove ownership of the received cryptocurrency. Typically, a public key is presented as an address, a shortened version of the public key itself. The private key, in contrast, should always remain confidential.
Public Key Cryptography
Public-key cryptography (PKC) is a cryptographic system that uses paired alphanumeric keys: public keys, which can be shared with others, and private keys, known only to their owner. Public keys are used to receive cryptocurrencies on the blockchain and, in combination with the corresponding private key, to send them. These keys are generated through cryptographic algorithms that create one-way functions. Public-key cryptography is also referred to as asymmetric cryptography.
P2P – Peer-to-Peer
A peer-to-peer network is a group of nodes (devices) that make up a decentralized network that can collectively share and store data, whereby each node acts as an individual peer.
Q
QR Code
A quick response (QR) code is a type of matrix barcode that uses a machine-readable optical label, often scanned with a mobile phone, to store sensitive information about the item it’s attached to. QR codes typically contain data for tracking, locating, or identifying that links to a mobile app or website. They store data using four standardized encoding methods (byte/binary, alphanumeric, numeric, and kanji).
R
RaaS – Rollups-as-a-Service
A RaaS consists of different rollups, namely a custom-built solution. These are considered to be simplified, elastic, flexible, ‘pay-as-you-go’ models designed to reduce complexity.
Recovery Phrase/Recovery Seed Phrase
A recovery phrase, also known as a “seed phrase” or “recovery seed phrase,” is a 12, 18, or 24-word code used as a backup to regain access to a cryptocurrency wallet if the private key is lost. This phrase corresponds to information stored within the wallet that can unlock the private key needed to restore access.
ReFi – Regenerative Finance
ReFi is an alternative financial system emphasizing the promotion and restoration of sustainability and resilience, not just monetary gains. In the blockchain ecosystem, this is often referred to as a cryptocurrency project that utilizes its platform for investments in sustainability, encompassing environmental, social, and financial stability and growth.
Rollups
A rollup is a type of modular layer 2 scaling solution that conducts transactions off the main blockchain to lower transaction costs and enhance throughput on the mainchain. It enhances scalability and performance by reducing the computational load on the primary layer 1 chain.
Rug Pull
A rug pull in crypto is a scam where the developers of a cryptocurrency project suddenly withdraw all the investors’ funds and disappear. This often happens with meme coins or new projects that seem promising but have malicious intentions. Essentially, investors are left with worthless tokens as the coin’s value drops drastically or the project is abandoned entirely.
RWA – Real-World Assets
Real-world assets encompass a wide range of physical, digital, or data-based assets that derive their value from existing outside the blockchain. Tokenizing RWAs involves creating a digital twin that resides on a blockchain.
S
Scalability
The scalability of a blockchain refers to its capacity to handle transactions, store data, and achieve consensus effectively as the network expands with the addition of more users.
Scrypt
Scrypt is the hash function used by Litecoin to convert an input of letters and numbers into an encrypted output. While it differs from the SHA-256 hash function used by bitcoin, it operates within a similar Proof of Work (PoW) consensus mechanism. Scrypt was initially designed to restrict mining to CPUs and GPUs, although scrypt-capable ASICs have since been developed.
Sharding
Sharding is a technique used to partition a blockchain network or other computer networks or databases to distribute computational and storage workloads across a wider set of devices or nodes. This approach enhances the system’s throughput and transaction speed by having each node maintain information related only to its specific shard or partition. Since each node handles only a fraction of the network’s total transactional load, the network’s overall processing capabilities and resilience are significantly improved. Consequently, sharding has enabled many blockchain networks to achieve faster transaction speeds, greater security, and better suitability for widespread enterprise use.
SHA-256
SHA-256 is part of the SHA-2 cryptographic hash function family, developed by the National Security Agency (NSA) and later became well-known as a core component of the bitcoin blockchain network. As a Secure Hash Algorithm (SHA), SHA-256 secures data using a cryptographic mathematical operation to generate a unique 256-bit, 64-character sequence of letters and numbers, known as a hash, from an input. These functions are typically designed to be one-way operations, making it nearly impossible to reverse-engineer the original data from its hash value.
Sidechain
A sidechain is an external secondary blockchain protocol linked to a primary blockchain network (mainchain). Sidechains enable the transfer of data and value between themselves and the mainchain and often use a different consensus mechanism. This allows for greater flexibility and scalability, as systems with robust sidechain interoperability can cater to a wider range of enterprise and individual users. Some sidechains facilitate asset transfers between multiple protocols, like Ethereum and Bitcoin, while others enhance layer 2 scaling solutions to boost the mainchain’s transaction speeds.
Smart Contract
A smart contract is a self-executing code or protocol that automatically enforces a set of instructions verified on the blockchain. These contracts are trustless, autonomous, decentralized, and transparent, becoming irreversible and unmodifiable once deployed. While they have many applications, some of the most common include financial contracts like loans, derivatives, and trading. They are also used in legal agreements, identity management, and various other scenarios. Popular in decentralized finance (DeFi), smart contracts can be combined into decentralized applications (dApps) to perform more complex functions.
Smart Contract Wallet
A smart contract wallet is a decentralized application (dApp) built on a blockchain that enables users to manage their digital assets using smart contract code.
Soft Fork
A soft fork is a backward-compatible blockchain update, allowing nodes with updated software to remain interoperable with those running the older version. Unlike a hard fork, where only new blocks are valid, soft forks involve less drastic protocol changes.
Source-Code Fork
A source-code fork is a type of hard fork where the original source code is used from an existing blockchain network to create a new one. As with all hard forks, source-code forks can render previously invalid blocks and transactions on the blockchain valid, requiring all nodes from the previous network to upgrade to the latest software protocol. Additionally, like other hard forks, source-code forks are not backward-compatible, meaning they cannot be reverted to their prior state.
Stablecoin
A stablecoin is a digital currency designed to maintain a stable value. Most stablecoins are directly linked to a specific fiat currency or tangible commodity, such as the Gemini Dollar (GUSD), which is pegged 1:1 to the U.S. dollar. However, some stablecoins achieve price stability through collateralization with other cryptocurrencies or algorithmic management of token supply. Since stablecoins maintain a relatively constant value, they are intended for use rather than as an investment.
State Data
State data is a snapshot of all data stored on the blockchain at a specific moment in time. This includes account balances, smart contract details, and other relevant information. The blockchain’s state is dynamic, changing with each transaction and smart contract execution.
Store of Value
A store of value is an asset that is anticipated to retain its value or purchasing power over time and can be reliably accessed and exchanged in the future. Historically, fiat currency, real estate, and precious metals like gold and silver have been considered reliable stores of value. As blockchain technology becomes more mainstream, many people also view certain cryptocurrencies, especially bitcoin (BTC), as an effective store of value.
Superchain
The Superchain is a concept designed by Optimism. It comprises a network of layer 2 chains, referred to as OP Chains, that jointly utilize security, a communication layer, and an open-source technology stack. The Superchain builds interconnected layer 2 rollup networks, or OP chains’ that share the standardized OP Stack architecture for seamless interaction, as opposed to creating isolated blockchains.
Unlike multi-chain designs, these chains are standardized and meant to function as interchangeable resources.
Sybil Attack
A Sybil attack is an online security breach where an attacker creates numerous fake identities that function as nodes to overwhelm and disrupt a target network. These attacks exploit the way legitimate nodes connect with each other. Sybil attacks can be particularly harmful to systems where new nodes can be created and synchronized with relative ease.
T
Testnet
An official testing network is an instance of a blockchain used for testing purposes. It consists of the same version of the mainnet underlying software. All testing and experimentation can be performed on the testnet without jeopardizing the actual mainnet.
Timestamp
A timestamp is a digital record that marks a transactirason’s precise moment. Timestamps logged onto a blockchain’s ledger are immutable and uniquely correspond to the specific transaction they record.
Token
A token represents a physical or virtual object or an abstract concept like a gift.
In the digital world, tokens vary. Crypto tokens function as digital keys on specific ledgers, unlike digital coins that are central to their systems.
A token is different from a coin in that it is created on top of an existing chain, as opposed to a coin that is native to its layer 1 blockchain. Crypto tokens serve multiple purposes beyond currency, such as providing access to services or representing ownership of digital art. There are generally five types of digital tokens: payment, utility, security, equity, and NFTs.
Token Liquidity
Token liquidity refers to the ease with which a digital token can be converted into digital assets or cash without impacting its price. Having good liquidity reduces investment risk and, crucially, facilitates the creation of an exit strategy, making it more straightforward to sell.
Tokenization
Tokenization involves transforming an asset or its ownership rights into distinct units known as tokens. Tokens are digital representations of an asset on a blockchain and generally serve as indicators of ownership for valuable assets.
TPS – Transactions per Second
The transactions per second (TPS) denotes the number of transactions a blockchain network can handle in one second.
Transaction
A transaction involves a contract, or agreement, such as a transfer, or exchange of assets between two or more parties. A blockchain transaction is a transfer of value from one address on a network to another. Simply put, it is a transmission of data across the network of computers within the blockchain system.
Token Transfer Transaction
A transaction type that transfers tokens from one account to another one. A token transfer transaction will transfer the amount of tokens specified in the amount property from the sender of the transaction to the specified recipient.
Trading Volume
In capital markets, trading volume refers to the quantity of a security traded within a specific time frame. It is usually reported as the number of shares exchanging hands during a trading session or period. Trading volume for any openly traded asset constantly fluctuates, and the direction and magnitude of these changes are key factors that many investors consider in their analysis.
Transaction
In a blockchain context, a transaction (TX) typically refers to the exchange of various types of data between users on a blockchain network. Depending on their origin, transactions can vary in speed, security, and privacy. The most common transaction type involves users exchanging network-specific coins or tokens.
Transaction Fee
A number of tokens that is required to send a transaction on the respective blockchain.
Transaction ID
A hash of a transaction that uniquely identifies a transaction.
Transaction Message
A transaction message is a piece of data signed by an external party. It represents either a message or a new autonomous object.
Transactions are recorded into each block of the blockchain. A message is created by contracts interacting with each other or by a transaction.
TVL – Total Value Locked
TVL is simply defined as the total value of cryptocurrency locked in a smart contract.
U
Unit of Account
A unit of account is a standard measure used to assess the value of a good or service. By assigning a specific measurement unit to an offering, its monetary value can be easily understood in abstract terms, eliminating the need for bartering. This function of providing a consistent measure of value is one of the three essential roles of money, alongside serving as a store of value and a medium of exchange.
Utility Token
A utility token is a digital asset designed to provide its holder with access to a blockchain protocol’s products or services. These tokens are meant for use within the blockchain’s network rather than as investments. However, because the value of most utility tokens tends to fluctuate based on the network’s popularity and adoption, many traders and crypto enthusiasts still buy them as speculative investments.
UTXO – Unspent Transaction Output
UTXO is an unspent output. In other words, it can be thought of as an indivisible chunk of a token that is under the control of the private keys belonging to the owners.
V
Validator
In the context of blockchain technology, a validator is an entity tasked with verifying and approving transactions submitted by users or blockchain clients. Each blockchain protocol defines its own criteria for what qualifies as a validator and how these validators function. Most decentralized blockchain networks depend on some type of validator node to process on-chain transactions in a permissionless and distributed way.
Vanity Address
Vanity addresses are cryptocurrency addresses customized according to specific parameters set by the user, making them more personal and easily recognizable while maintaining security. For example, bitcoin vanity addresses are like regular addresses in functionality but include a personalized alphanumeric string, message, or special word chosen by the owner.
Volatility
Volatility refers to the extent to which an asset’s trading prices fluctuate relative to its average price over a specific period. The more volatile an asset is, the more frequently and significantly its price changes. Volatility is typically measured using standard deviations of logarithmic returns. Many investors monitor an asset’s volatility to spot and exploit potential trading opportunities based on perceived price trends. However, excessive and unpredictable price swings often deter investors with lower risk tolerance.
Volume
Volume measures how frequently a specific coin or token is traded within a certain time frame. Investors use this metric to gauge the popularity of buying or selling an asset at any given moment. Volume indicates the total monetary value of a cryptocurrency traded over a period and is crucial because it significantly influences price, both in absolute and relative terms. See trading volume.
W
Wallet
Wallets can be divided into three distinct categories: software, hardware, and paper wallets. Software wallets can be desktop, mobile, or online.
In short, a wallet will store public keys and private keys and can interface with various blockchains, enabling users to monitor their balance, send tokens, and conduct other operations.
Web2
Web 2.0 emerged in the early 2000s as a second wave of internet innovation characterized by its interactive, read-write design. Platforms like Amazon, Facebook, Airbnb, Alibaba, and X spearheaded this era by providing dynamic, multi-functional applications across various devices. However, Web 2.0 has faced criticism for being overly centralized and fostering excessive profit-driven practices, intrusive advertising, mass surveillance, reduced privacy, and widespread data theft.
Web3
Web3 is the next generation of the Internet, in which all applications are decentralized and can run on the blockchain. Web3 enables most users to be linked through decentralized networks and maintain control over their own data.
The four core concepts of Web3 are decentralization, artificial intelligence, and machine learning, trustless and permissionless networks, and omnipresent connectivity.
The first version of the Web (Web 1.0) was the “read-only Web,” and the second version added the ability to “write.” Web 2.0 is described as the “participative social Web.” Web3 goes a step further and can be classed as the “read, write, own, Web.” This stage shifts users away from centralized platforms such as Facebook and Google.
Whitepaper
A whitepaper is a report-style document that explains a complex issue within a specific industry or field and outlines how an enterprise addresses that problem. Typically, whitepapers introduce a business model and development plan. In the context of blockchain, a whitepaper is often one of the first documents created once a project has a working product and initial funding. It also serves as a pitch to attract additional investors. Blockchain-specific whitepapers usually include details on the technical architecture, token economics, team, and other relevant information.
Wrapped Token
A wrapped token is a digital asset tied to another cryptocurrency’s value. It’s called a wrapped token because the original asset is secured in a specialized digital vault, enabling the creation and use of the wrapped token on a different blockchain. This process allows the asset to benefit from the unique functionalities offered by different blockchains, thereby expanding its utility across various networks.
Y
Yellow Paper
In traditional contexts, a yellow paper can have a broader meaning. Still, in the blockchain space, it usually refers to a highly technical document detailing the specific technical components of a blockchain or related system. Yellow papers are often more concise than white papers, focusing on the most complex technical aspects of a blockchain protocol.
Yield Farming
Yield farming involves staking or locking up cryptocurrencies within a blockchain protocol to earn tokenized rewards. Many decentralized finance (DeFi) projects use yield farming to encourage users to provide liquidity and maintain network stability, as these projects operate without a centralized market facilitator.
Z
Zero Knowledge Proofs
A Zero-Knowledge Proof (ZKP) is a cryptographic method that offers enhanced privacy for users in digital transactions. Essentially, ZKPs allow one party to prove to another that they possess a particular piece of information without revealing any details about that information itself. These proofs enable the verification of information without disclosing any specifics about the underlying data or the identities of the parties involved in the transaction.
Zero Knowledge Rollups
A zero-knowledge rollup (zk rollup) is a layer 2 scaling solution that shifts computation by executing them off the main blockchain (off chain) while still storing the transaction data on the main blockchain and retaining the transaction data on chain in a layer 1 network. By using zero-knowledge proofs, off-chain computation results are proven valid on chain.
Unlike optimistic rollups, which assume transactions are valid and only verify them if challenged, zk-rollups immediately verify the validity of transactions using zero-knowledge proofs. This results in faster finality and increased security but can be more computationally intensive.
Zero Knowledge Snarks
A Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk SNARK) is a cryptographic proof used to maintain privacy in blockchain-based distributed ledger systems. It allows one party to prove they have specific information without revealing the actual data to the network by using a secret key before the transaction is broadcast. Zk SNARKs gained prominence with privacy-focused blockchain protocols like Zcash and Monero.

Collab Collections
Our store aims to offer “stylish, cool, and modern” fashion products. The original collection is our first step in that direction, earning us the necessary experience in this field.
This is where the Collab collections become important. The strategy involves regularly partnering with established artists to produce new collections aligned with our goals. Ideally, these artists will be digital creators with their own NFT collections. By collaborating with them, we can attract their audience to the Onchain brand, and they will be incentivized through revenue sharing.
Each collaboration NFT should serve a distinct purpose. For example:
- Onchain Honorary: Acknowledging individuals who are honorary members of the Onchain Club.
- Onchain x Dmitri Cherniak: An artistic collaboration featuring Dmitri Cherniak, combining his exceptional talent with Onchain’s innovative ethos.
D
DeSci Vision for Onchain
The “internal rationale” for evolving Onchain.org into a more decentralized-based Web3 research platform was largely driven by Onchain’s vision and mission. This transformation is a natural progression in our quest to enhance Web3 research and ultimately create a better “world” where utilizing onchain solutions brings meaningful improvements.
E
Entrepreneurs
An entrepreneur builds onchain use cases that address both of our external goals. Both non-Web3 and native Web3 entrepreneurs already understand blockchain technology and Web3. With our resources, we inspire and enable them to conceptualize and build their own onnchain use cases.
M
Magazine
The magazine mainly serves as a source of information about how blockchain improves the world in various aspects of life. The Onchain research reports are repurposed by breaking down their content into several shorter articles in our digital magazine. The idea is to help entrepreneurs, start-ups, and investors find solutions for their own challenges. We also address current topics of interest to our target audience. New magazine articles are distributed through our social media channels.

Non-Web3 Businesses
Non-Web3 businesses, sometimes also referred to as Web 2.0 businesses, are businesses that have not engaged in Web3 so far. Many businesses can benefit from implementing blockchain technology; often, there is simply a knowledge gap. Onchains’ research supports those businesses that desire to engage with Web3 but lack the knowledge or creativity to come up with promising onchain use cases. Ultimately, targeting non-Web3 businesses can pave the way for tailored studies and further collaborations.
