🛠 Saturn & IPNI: Finding and fetching Web3 Content
summary
Saturn is a decentralized CDN launched Nov 2022 that serves IPFS/Filecoin content with 2,000+ points of presence and about 158M daily requests, claiming ~11+ Tbps capacity. Clients use a DNS/browser widget or the Caboose SDK to hit a Saturn L1 node and a service worker incrementally verifies streamed HLS video chunks; cache misses query IPNI (the network indexer) for provider records and retrieve via GraphSync or HTTP. Payouts run on FVM smart contracts; micropayment and UCAN access-control work is still research.
