NBA Top Shot Moments will now be permanently stored on IPFS, a decentralized network, making each one a collectible that exists in perpetuity – independent of any single entity.
Every video highlight, the thumbnail, and metadata.
Built in collaboration with the NBA and Dapper Labs, this is expected to be announced this week.
Explainer follows.
IPFS (InterPlanetary File System) is a decentralized, peer-to-peer storage network used to store, share, and access files and data without relying on central servers.
IPFS is made of multiple IPFS nodes, so no one entity can control what is shared on the network, this allows immutability (unchangeable data) and permanence - but only if the data is pinned to at least one node.
Pinning is what turns "accessible in theory" into "accessible permanently."
The more a Moment is requested, the more nodes it passes through, and the more opportunities for it to be pinned organically by others.
This can also be done deliberately through a pinning service as well, and Dapper Labs would likely use one or several of these to ensure redundancy.
Whenever a node wants to share content on IPFS, it runs the content through a cryptographic hash and returns a CID (Content Identifier).
The CID is tied to the content itself – change anything at all, and you get a completely different CID – this is what makes it tamper-proof.
Moments will have a public CID, so anyone can independently verify the media is authentic and access the original files directly – no middleman needed.
Moments will become decentralized IPFS-pinned assets to ensure they remain accessible forever, so even if Dapper Labs ceased operations, your collectibles would still exist and be retrievable, no matter what.
