The InterPlanetary File System (IPFS) is a decentralized protocol for distributed file storage and sharing. It uses a peer-to-peer network to connect nodes globally, distributing data across them. IPFS uses content-based addressing with unique cryptographic hashes for each file, ensuring data integrity. It’s open-source and aims to create a more resilient web. djuno offers fully managed Ipfs Server that you only pay for the disk usage.

By signing up for Djuno Cloud, you receive a fully managed Kubo instance on a pay-as-you-go basis. This includes access to all Kubo APIs and a user-friendly dashboard UI. In the IPFS Dashboard, navigate to the “Files” tab to easily create folders and upload files using drag-and-drop or the upload button.

You can also whitelist hostnames to have access to your endpoint. If the API request arrives without a whitelisted domain name in the Referrer or Origin HTTP header, the request will be denied.

IP whitelisting is another feature that is available to your QuickNode endpoint. You can add up to 25 IP addresses you wish to whitelist for your endpoint. This security feature differs from referrer whitelisting as it takes an IP (e.g., 123.123.123.123)
