In 2024, CryptoCrew has received a grant from the AADAO to operate and maintain a public archive node for the Cosmoshub, providing full block history and transaction data from the genesis block of the `cosmoshub-4` mainnet up to the most recent block.
This node is primarily targeted to support Cosmos Hub developers, key integrators, and dApp partners, giving them reliable and responsive access to Hub’s historic data. This is a key piece of infrastructure required by the Hub, which has thus far only been available in a fragmented, inconsistent or voluntary manner.
As the AADAO has since been wound down, we are presenting our latest milestone report to the Cosmoshub community through this forum post.
Service Level Agreements (SLAs)
Uptime (over the last 30 days): 99.9%
Rate limit: 5 requests / sencond per unique client IP
As the service period for this grant approaches its conclusion, we are in discussions with Cosmos Labs (ICF) regarding a potential renewal of the contract and continuation of the service. We invite community members and developers who have benefited from this service to share their feedback or support in the comments below.
Great work on keeping this essential piece of Cosmos Hub infrastructure running, CryptoCrew team
KYVE fully recognizes the value of having a reliable archive node available for developers and integrators; it’s a key need for the entire community. In parallel, we believe the Cosmos Hub’s long-term data infrastructure should gradually evolve toward a trustless and decentralized model, where historical data is permanently available, censorship-resistant, validated, and without rate limits or centralized gatekeeping.
KYVE’s approach, leveraging decentralized validation and permanent data storage (e.g. Arweave), provides a fully open and verifiable archive of Cosmos Hub data. While this infrastructure may appear more resource-intensive during setup, it drastically reduces costs and dependencies over time, offering a sustainable solution beyond hosting cycles or grant renewals for the following decades, as it has been implemented by other L1S such as Celestia, Story, Avail, dYdX, and others.
We would be happy to collaborate with the ICF, Cosmos Labs, and CryptoCrew to align efforts and create a unified, decentralized data infrastructure for Cosmos Hub. Combining the strengths of both approaches, CryptoCrew’s reliable operational services and KYVE’s decentralized data validation and storage, could deliver the best of both worlds to the Hub and its community.
The KYVE team is looking forward to discussing possible synergies to build a future archival data layer for the Hub.
To be blunt here, I would oppose you receiving more money. Your last post was Nov. 2024, and the public archive node link was poorly advertised to newcomers. Where was it advertised on the forum at all? I’ve been paying for quicknode since I had no idea this was actually delivered. I also emailed AADAO for the link since this was funded and got ghosted.
