 ## Publish Blob
 
 Blob can be published by authorizing read interface (e.g. IPFS gateway) by re-delegating `LocationClaim` for a corresponding blob to it.
 
-> Note that same applies to publishing blob on IPNI, new capability is not necessary, user simply needs to re-delegate `LocationClaim` to the DID representing IPNI publisher. IPNI publisher in turn may publish delegation to DID with publicly known private key allowing anyone to perform the reads.
