How KYVE Replaces Archival Nodes For Efficient Blockchain Data Management

In blockchain, data accessibility and management are critical components that ensure the transparency and security of decentralized networks. Whether you are starting a new blockchain project or are already running one, every transaction, every block, and every piece of data must be accessible not only in the present but also preserved indefinitely for future reference.

‍

This is where archival nodes come into play. These nodes can store the entire history of a blockchain, making it possible to query any event or transaction from the past. However, despite their importance, archival nodes come with significant challenges—scalability, cost, and resource intensity being the most pressing. So what is the solution?

‍

This overview will explore how archival nodes store data, the limitations of archival nodes, especially when blockchains grow exponentially, and KYVE as a cost-effective and scalable data management solution.

‍

TL;DR:

• KYVE revolutionizes blockchain data management by replacing traditional archival nodes with a scalable, decentralized model. It offers a more accessible, secure, and efficient way to store and manage blockchain data, addressing the challenges that archival nodes face as blockchain ecosystems grow.

• With Arweave as a storage provider, KYVE ensures long-term data retention, with upfront payment for 200 years of storage and 20 data replicas for security. Unlike archival nodes, KYVE offers free and unlimited data retrieval, making it a cost-effective solution for projects of all sizes.

• KYVE’s free tools, such as KSYNC, drastically reduce the time to sync nodes, turning what would normally take weeks into minutes. This allows developers and validators to focus on building and optimizing their applications, instead of dealing with long sync times.

• Incentives and validation are at KYVE's core: Validators in KYVE’s network are rewarded for ensuring accurate and tamper-proof data storage, while penalties keep the system secure and reliable, creating an efficient and trustworthy ecosystem for blockchain data.

Understanding Archival Nodes

Public blockchains operate as a global network of interconnected computers, commonly called nodes. These nodes play a crucial role in storing, processing, and verifying data on the blockchain, ensuring the integrity and security of the network.

‍

While all nodes are responsible for maintaining the blockchain, they serve different purposes based on their capabilities. Archival nodes, which we will explore in detail in this section, store the complete historical data of the blockchain, making them invaluable for querying past transactions and states.

‍

‍

Unlike other types of nodes, such as light nodes, which store only the most recent block headers and rely on other nodes for data verification, or full nodes, which store all the data from the genesis block onward but don’t maintain older states in a detailed format, archival nodes go beyond validating transactions and maintaining a portion of the blockchain—they store every piece of data generated by the network, no matter how old or seemingly insignificant.

‍

To understand their role more clearly, here’s a comparison of the three types of nodes:

‍

As seen, the critical function of archival nodes is to ensure historical transparency and accurate data validation. Without efficient data management, it would be nearly impossible for blockchain networks to offer a full audit trail, as querying older transactions or states would be significantly slower or, in some cases, impossible. This is why many blockchain projects rely on archival nodes to support dApps, research, and audits that require comprehensive access to past data.
‍

The Limitations of Archival Nodes

While archival nodes are necessary for maintaining a complete history of blockchain data, their high costs and demanding management requirements make them accessible only to a few entities, and even then, they can become unsustainable in the long run. This creates significant barriers to broader adoption and potentially hinders the growth and accessibility of blockchain ecosystems.

‍

Here are some of the limitations of archival nodes:
‍

1. Lack of Scalability: The most pressing issue with archival nodes is their inability to scale effectively. As blockchains expand and more transactions are processed, the data required to store the entire history grows exponentially. For example, as per Etherscan, at the time of writing, Ethereum’s blockchain size has grown to 1100+ gigabytes, more than doubling in size in the last two years —  and the demands continue to increase! Archival nodes must store all of this data, which results in a bottleneck, and only a few entities with vast resources can manage the infrastructure required for archival nodes. As a result, this creates a situation where blockchain data becomes less accessible to the broader community.
   
2. High Operational Costs: Running an archival node requires significant resources, including storage, bandwidth, and processing power. The sheer amount of data stored by archival nodes means operators must invest in large-scale hardware and constantly upgrade their infrastructure to keep up with blockchain growth. This translates to high operational costs, making archival nodes a viable option only for entities with large financial backing, such as exchanges or large blockchain enterprises. Smaller developers and projects are often left out due to these prohibitive costs.

3. Latency and Syncing Issues: Archival nodes often experience delays when querying and syncing data, especially as the blockchain history becomes more extensive. This latency can significantly slow down dApp performance, leading to longer wait times for users accessing specific historical transactions or data points. The longer it takes for an archival node to sync with the network, the more the performance of dApps relying on that data is affected.

4. Centralization Risks: Due to the high costs and technical requirements, only a small number of participants in most blockchain networks run archival nodes. This centralizes control over historical data, introducing risks associated with centralization. If these few nodes go offline or become compromised, access to the entire history of the blockchain could be severely impacted.

‍

These limitations highlight the need for a more decentralized and scalable solution, which is where KYVE steps in. KYVE offers a decentralized, cost-effective way to store, access, and manage blockchain data, eliminating the bottlenecks and risks associated with traditional archival nodes.

‍

Why KYVE is the Ideal Replacement for Archival Nodes

As blockchain networks evolve, a scalable, cost-efficient, and decentralized solution for storing and managing historical data has become critical. KYVE offers a next-generation approach to blockchain data storage designed to overcome the limitations of traditional archival nodes.

‍

KYVE enables projects to store blockchain data with decentralization, distributing it across data pools, which are then uploaded and verified by validators for use.

‍

Here’s how it works:
‍

1. Data Pool Creation: The process begins when participants, through KYVE’s governance system, initiate the creation of a data pool.
   
2. Data Upload, Fetching, and Bundling: Validators are selected through an algorithm to act as "uploaders." These uploaders fetch a specific range of blockchain data, bundle it together, and securely upload it to decentralized storage platforms such as Arweave or Filecoin. This process ensures that data is efficiently gathered and securely stored in a decentralized manner, making it accessible for future verification and use.
   
3. Storage Hash Sharing: Once the data is stored, the uploader generates a SHA256 checksum and storage ID, with which the other validators can download the full bundle and do the comparison. The storage hash and other metadata are also validated.
   
4. Cross-Validation and Voting: The other protocol validators independently fetch the same range of data and verify it against both the uploader’s hash and the uploaded data. They then vote on whether the bundled data is accurate. If a consensus is reached, meaning the majority agree that the data is correct, the storage hash is recorded on the KYVE blockchain permanently as the verified data bundle. The storage ID points to the location where the correct data is stored, and other details, such as the storage hash are stored on the KYVE chain.
   
5. Incentives and Penalties: Validators that vote incorrectly—those who do not align with the majority—are penalized and face slashing of their stake. Similarly, uploaders who provide incorrect data bundles are also slashed. This entire process operates on a Delegated Proof of Stake (DPoS) system, ensuring that the network remains secure and data integrity is maintained.

This decentralized model ensures that no single entity controls the data, making the system resilient to data loss, corruption, and inaccuracies. KYVE also incorporates a token-based incentive system, which rewards validators for their accurate contributions while penalizing those who act incorrectly. This mechanism not only enhances the network's security but also promotes efficiency and trust within the system.

‍

As highlighted above, one of the biggest hurdles with traditional archival nodes is their inability to scale efficiently as blockchain data grows. KYVE addresses this problem by decentralizing data storage across its network and distributing the responsibility across many participants rather than relying on a few nodes to store the entire blockchain history.

‍

KYVE ensures that the blockchain data is carefully validated and schematized through its decentralized validators. Although each validator must sync and verify the entire data set, KYVE guarantees the data’s integrity and availability through this rigorous validation process. Once the data has been verified and stored on decentralized platforms, participants can shut down their nodes, confident that the data will remain accessible and tamper-proof for future use.

‍

When comparing the cost structures of KYVE and traditional archival nodes, a key differentiator lies in KYVE’s use of Arweave as a storage provider. With Arweave, storage fees are paid upfront for a period of 200 years, offering long-term data availability without the need for ongoing payments. Additionally, for every 1GB of data stored in KYVE, there are typically 20 replicas created, meaning you’re effectively storing 20GB to ensure data redundancy and resilience. This replication model provides high levels of security and data integrity.

‍

Moreover, data reading and querying in KYVE are free and unlimited, ensuring that users can access and retrieve their data without incurring additional costs—a significant advantage over traditional archival nodes, where querying large historical datasets can be expensive and resource-intensive.

‍

Here’s a brief comparison between KYVE and archival nodes:

Multi-Coin Funding For Validators

KYVE is already being implemented in applications where traditional archival nodes would be impractical. Through its decentralized data pools, KYVE has validated and archived over 7TB of historical data from chains like Cosmos Hub, Axelar, Celestia, etc.

‍

Moreover, projects across multiple blockchain networks are using KYVE to store historical data in a decentralized manner, reducing costs and improving data accessibility. To ensure that data is efficiently and accurately managed, protocol integrations rely on funds from the blockchain teams or their foundations, validations, projects, and users, who rely on KYVE’s data pools and tools.

‍

These funds pay well-behaved validators and their delegators within each data pool (integration), incentivizing them to secure, archive, and validate historical Web3 data. Since KYVE’s launch, integrations have been primarily funded by the KYVE Foundation, and validators received $KYVE tokens for acting positively.
‍

For an improved funding experience, KYVE has introduced the multi-coin funding feature,  which allows data pools to be funded with tokens other than $KYVE, enabling other projects to fund their integrations on KYVE with their own native tokens. 

‍

This not only brings opportunities for new ecosystem collaborations but also ensures validators can diversify the potential of their earnings with good behavior. $KYVE will remain the token used for delegation on the chain and protocol layers, and validators will soon leverage it to pay for data storage.
