APIs are a set of protocols, routines, and tools for building software and applications. They define the ways in which different software components can communicate and interact with each other. APIs provide a way for developers to access and interact with a blockchain network or decentralized application, allowing them to submit transactions, retrieve data, and execute smart contract functions.

Archival Nodes

Archival nodes are a type of blockchain node that stores a complete historical record of all transactions and data on the blockchain. Unlike full nodes that store only recent blockchain data, archival nodes retain the entire historical ledger, making them valuable for research, data analysis, and historical data retrieval but requiring significantly more storage capacity, causing them to be very costly and unsustainable as Web3 expands. KYVE provides the perfect solution for users needing historical data but unable to run their own archival node or pay to access one, thanks to its data pools archiving chain data, making it a trustless, public good.


The Arweave network is like Bitcoin, but for data: A permanent and decentralized web inside an open ledger. Permanent storage has many applications: from the preservation of humanity’s most important data, to the hosting of truly decentralized and provably neutral web apps. KYVE leverages Arweave to store the historical data it validates, together, ensuring that historical data is a trustless public good.


A blockchain is a decentralized and transparent digital ledger that records transactions across multiple computers or nodes, providing immutability, security, and trust in a tamper-resistant manner.


A data bundle refers to a collection of data that is packaged into a single unit. Data bundles can also be used for different industries, such as the distribution of digital content or the sale of data services. The idea behind data bundles is to provide customers with a convenient and cost-effective way to access and use data, while also allowing providers to better manage their network resources and monetize their data offerings. KYVE bundles its data in order to reduce pressure on storage capacity and better organize data in the Web3 space in a cost-effective manner.

It can come in various forms, such as text, numbers, images, audio, or video. Data is a valuable resource that is used by individuals, businesses, and governments to make informed decisions, gain competitive advantages, and drive innovation and progress.

Data Availability

Data availability is a concept in blockchain technology that ensures all necessary data for verifying blockchain transactions is readily accessible to network participants. This addresses the issue of data being withheld, which can compromise the integrity and security of a blockchain. By guaranteeing data availability, it ensures that participants can validate transactions and the blockchain’s history, maintaining trust and reliability in the system. This concept is especially significant in decentralized networks where trust and verification are distributed among many participants.

Data Lake

A data lake is a repository that allows organizations to run their structured and unstructured data through at any scale. The data lake is designed to store data in its raw format, without imposing any structure or schema upfront, allowing for greater flexibility and scalability in data management and analysis. KYVE, for example, is a decentralized data lake.

Data Pipeline

Data Pipeline is KYVE’s no-code solution for providing Web2 and Web3 with trustless data. More specifically, it is an ELT pipeline custom data source supported by Airbyte that allows data analysts and engineers alike to easily import KYVE data into any preferred data backend, such as MongoDB, Google BigQuery, SQL Databases, and more.

Data Pools

KYVE’s data lake is made up of data pools, with each pool pertaining to a certain type of data. For example, Solana blockchain data, or weather data from a certain region. Each data pool has a certain amount of protocol validators within it working together to fetch, store, and validate the data requested. Using such a structure allows data sets to be properly organized and easily sourced.

Data Rollups-as-a-Service (DRaaS)

Data rollups allow for off-boarding of a blockchain’s historical data management (such as storage and accessibility tooling). In doing so, blockchains can scale without limits, while still providing their ecosystems with the data support they need to thrive. Data Rollups-as-a-Service means providing this historical data off-boarding as a service for blockchains to implement, which is exactly what KYVE does.

Data Validation

Data validation is the process of clarifying the accuracy, integrity and quality of a set of data before it is used. This can apply to all forms of data, for example, specific text, addresses, dates, and more. Find out more in KYVE’s article on the CoinMarketCap Glossary.

Data Warehouse

A data warehouse is used for storing processed and organized data for reporting and analysis. The data in a data warehouse is typically transformed, cleaned, and integrated from various sources before being stored in a well-defined schema. Data warehouses are typically used for traditional business intelligence and decision support systems.


Decentralization refers to the distribution of decision-making authority and power away from a central authority or entity and towards multiple actors or nodes in a network. In a decentralized system, there is no single point of control or failure, making it more resistant to censorship, fraud, and manipulation. Decentralization can be applied to a variety of systems, such as economies, governments, organizations, and technology, and is often associated with concepts like democracy, transparency, and accountability.

Decentralized Storage

Decentralized storage solutions allow users to store data across a distributed network of nodes, removing the need for a central server. Examples include IPFS (InterPlanetary File System), Arweave, and Filecoin.

Delegated Proof of Stake

The consensus method called Delegated Proof of Stake (DPoS) is a version of the traditional Proof of Stake (PoS) scheme. With DPoS, which developed from PoS, network users can elect representatives to verify blocks.


Delegators are participants who hold tokens in a proof-of-stake (PoS) blockchain network and delegate those tokens to a validator. Delegators play an essential role by supporting validators and actively participating in the consensus mechanism, thereby contributing to the security and stability of the blockchain network. By delegating their tokens, delegators entrust the validator with the responsibility of validating transactions and maintaining the network’s integrity.

Deterministic Data

Deterministic data is generated or produced through a fixed, predictable set of rules or algorithms. This means that given the same initial input or conditions, the output or result will always be the same. This ensures that all participants can agree on the state of the network and the validity of the data. KYVE can only archive & validate data that is deterministic; this way, we can find if it’s 100% true or not.


ELT (extract, load, transform) is a data sourcing approach. It allows data to be extracted from various sources, transformed into a format that is suitable for analysis, and then loaded into a data storage system for further processing and analysis. ELT pipelines are commonly used in big data environments to efficiently process and analyze large volumes of data in real-time. KYVE’s Data Pipeline is an ELT Pipeline, offering a no-code solution for easily importing KYVE data into storage backends.

A node refers to a computer or device that participates in the network. Nodes can perform various functions in a blockchain network depending on the type (full node, supernode, light node, etc.), including validating transactions, maintaining the integrity of the blockchain, and relaying information to other nodes in the network. Mainly acting as a way of fetching data from the blockchain.


An Oracle refers to an entity that provides external data to smart contracts on the blockchain. An oracle acts as a bridge between the blockchain and the outside world, allowing smart contracts to access and interact with data from various sources such as stock prices, weather information, or other APIs. By providing access to off-chain data, oracles play a crucial role in enabling the use of blockchain technology for a wide range of real-world applications. However, in order to provide data quickly, oracles are typically centralized.

Private Key

A private key is a cryptographic code used in asymmetric encryption systems that is kept secret and used to decrypt data or generate digital signatures.

Proof of Stake

Proof of Stake (PoS) is a consensus mechanism used in blockchain technology to validate transactions and achieve network consensus. Instead of using computational power to validate transactions, PoS uses the stakeholder’s economic investment in the network, and validators are chosen proportionally to their stake. This reduces the energy consumption compared to Proof of Work (PoW) and incentivizes long-term holding of the network’s cryptocurrency.

Proof of Work

Proof of Work (PoW) is a consensus mechanism used in blockchain technology to validate transactions and produce new blocks. In PoW, nodes solve a cryptographic puzzle to add new blocks to the chain and receive rewards for their work. This process consumes significant computational power, which is intended to prevent malicious actors from controlling the network and provides security to the system.

Protocol Layer

The protocol layer sits on top of the consensus layer in KYVE and enables its actual use case, including data retrieval, archiving, and decentralized validation. The Protocol Layer is made up of data pools, each pertaining to a specific set of data, and run by a set of validators.

Protocol Validators

KYVE has two layers to its blockchain, the consensus layer, and the protocol layer. The protocol layer is technically KYVE’s data lake. This layer relies on validators called protocol validators. Protocol validators work as both uploaders and validators, and therefore are responsible for fetching data from a data source, validating the data, and storing it.

Public Key

A public key is a cryptographic code used in asymmetric encryption systems that is shared openly and used to encrypt data or verify digital signatures.


REST-API stands for Representational State Transfer Application Programming Interface. The REST-API is a resource model outlining the major details you need to know about a given piece of data. For example, where and how it’s being stored. For KYVE, its data is available through the REST-API exposed by its consensus validators.


A rollup is typically known to handle the computation layer of a blockchain, which means aggregating and processing multiple transactions off a main blockchain. Once processed, the transactions are bundled together and their collective state is submitted to the main blockchain as a single transaction, ensuring security and finality while greatly enhancing scalability. KYVE provides data rollups-as-a-service, meaning instead of handling computation, KYVE handles the data of a main blockchain, and can create custom data rollups per chain.


The runtime is the environment in which a decentralized application, smart contract, or other blockchain-based system executes and runs. The runtime provides the necessary resources and infrastructure for the execution of the application, including memory, processing power, and storage. The runtime is a critical component of a blockchain-based system, as it provides the necessary resources and infrastructure for the execution and running of decentralized applications


An SDK (Software Development Kit) for blockchain technology is a set of tools and libraries designed to help developers build decentralized applications on a specific blockchain platform. An SDK usually includes APIs, documentation, and code examples to simplify the development process and allow developers to easily interact with the blockchain’s underlying technology. This helps developers quickly create and deploy applications without needing to have a deep understanding of the underlying blockchain technology.

Smart Contracts

Smart contracts are self-executing contracts with predefined rules and conditions that automatically execute and enforce agreements without the need for intermediaries. They are powered by blockchain technology and ensure transparency, security, and efficiency in various sectors.


State synchronization (state-sync) allows new or restarting nodes to quickly catch up to the current state of the blockchain by downloading a snapshot of the state at a specific block height, rather than processing every transaction from the beginning. Before, finding state snapshots was difficult and time consuming. Now with KYVE and its node tool KSYNC, a state-sync snapshot of any supported chains can reliably and freely be applied to your node. After the snapshot is applied, the node can continue block-syncing from the applied snapshot height.


Being storage-agnostic means that an application, protocol, or platform is designed in a way that it can work with various storage solutions without being dependent on any particular one. Being storage-agnostic is important in the Web3 ecosystem because it promotes interoperability and prevents vendor lock-in. It ensures that changes or improvements to storage technology can be incorporated into applications without major disruptions, making the ecosystem more adaptable and future-proof.


The KYVE Team developed Supervysor, a node runner tool that eases the overall node experience on KYVE’s protocol layer, ensuring that the required node on the original chain can keep the same pace as KYVE’s data pools by pruning the unnecessary data. Overall, this helps the node runner avoid high storage costs and optimize overall management.


A testnet is a sandbox environment used for testing and development purposes in blockchain technology. It is a separate, isolated network that is used to develop and test decentralized applications, smart contracts, and other blockchain-based systems before they are deployed to a live network. The purpose of a testnet is to provide developers with a safe and controlled environment for testing and debugging their code, without risking the security or stability of the live network.


A token is a digital asset that is used to represent a specific value or utility within a blockchain-based system. Tokens can be used for a variety of purposes, such as representing a financial asset, a utility within a decentralized application, or a representation of ownership or stake in a particular blockchain network.


Tokenomics is an important factor in the success of blockchain and decentralized systems, as it can determine the incentives and motivations of participants, the demand and supply dynamics, and the overall health and stability of the network. It encompasses the rules and incentives that govern the creation, distribution, and usage of tokens, as well as their value proposition and underlying economics.


Trustless refers to a system or a technology that operates without relying on trust in any single entity or centralized authority. It is a characteristic of decentralized systems, where transactions and interactions are verified and validated through a consensus mechanism, eliminating the need for intermediaries or central authorities to establish trust. Trustless systems are designed to minimize the risk of fraud, hacking, or manipulation, as all participants have a shared and transparent view of the state of the system, making it more secure and reliable.

Trustless Data

Trustless data refers to data processed and verified by a network of actors incentivized to behave accordingly. This eliminates the need for a central authority or intermediary to verify and validate the data, avoiding single-point of failure and inconsistencies. Trustless data is crucial for developers, node runners, data engineers, and more that need truly accurate data in order for their solutions to run properly.


An uploader is a protocol node that is randomly selected in a pool to fetch and upload the requested data. Each pool has one uploader at a time. After a piece of data has been validated and stored, the uploader role is switched to another protocol node in the pool in order to eliminate any influence over the data.


Validators are a type of node that produces blocks and participates in the Proof of Stake process. KYVE has two sets of validators, one for its consensus layer, and one for its protocol layer. Thanks to our network of validators, KYVE is able to bring forward trustless data and perform in a decentralized, transparent way.

Validator Commission

Seeing that KYVE is a Delegated Proof of Stake blockchain, stakeholders have the option of delegating their stake to already active validators rather than running a validator of their own. In doing so, they help secure the network while also getting the opportunity to earn rewards (with the risk of loss). When delegating to a validator, the validator itself chooses its commission rate. The higher the rate, the lower the rewards for a delegator.

Web 2.0

Web 2.0 refers to the second generation of the World Wide Web, characterized by increased user interactivity and collaboration, greater social networking capabilities, and the development of new technologies and platforms, such as blogs, wikis, and social media websites.
