Today's web is inefficient and expensive HTTP downloads files from one server at a time — but peer-to-peer IPFS retrieves pieces from multiple nodes at once, enabling substantial bandwidth savings. With  up to 60% savings for video,  IPFS makes it possible to efficiently distribute high volumes of data without duplication. Today's web can't preserve humanity's history The average lifespan of a web page is 100 days  before it's gone forever. The medium of our era shouldn't be this fragile. IPFS makes it simple to set up resilient networks for mirroring data, and thanks to content addressing, files stored using IPFS are automatically versioned. Today's web is centralized, limit
