yes! It is. Another huge cost involved with stored data that must be accessible anywhere by anyone online - not health records of course - is the redundancy it takes for the big players to provide quick access to said data from any geographic location. They accomplish this by leasing storage in data centers, or building their own, worldwide. this is one reason X has such a huge reach, a network of global redundant storage makes it possible for the app to work quickly anywhere and it must cost a fortune to provide. With social media, the nostr model lets us all distribute the load globally providing a similar kind of redundancy through the relays. The p2p, fediverse, whatever we call it, distributed data model is superior to the commercial solutions for too many reasons to list, one of them being the guaranteed, continuous availability of the ledger regardless of its size, because so many who do so are motivated by ideological reasons, not profit (thank you node runners) and in huge numbers this can’t be stopped by authorities or market crashes. I predict the ledger will be fine at a petabyte because by then, the hard drives we’ll be using will be 100 exabytes, and our internet connections will be measured in Tbps, and we’ll laugh at today’s standards the way we laugh about yesterday’s now.
