I don’t actually want to do this right now, but I do want to know if it’s really decentralized yet. Completely looks like it means each of:
- A client ✅
- A personal data server ✅
- A relay ❓
- Labelers ✅
- Feed generators ✅
It looks like the relay might be the bottleneck. If I’m understanding the protocol correctly, a relay could consume less than the whole network so it doesn’t have to be ridiculously expensive to operate, but I’m not finding examples of people doing it.
My friend, it’s not nonsense, it’s basically how decentralised communication has to work if you want any reasonable level of recency & history in the data.
Usenet was basically the original and I believe a modern news provider requires something like 50 petabytes of storage to run a 10 year data retention service
Not the person you replied to-
I don’t follow why it would be necessary, would you mind expanding on why its needed for decentralized interaction to function the way users would expect?
(Also I recognize that might be a huge can of worms, if you do mind thats perfectly understandable. You seem more knowledgable than myself and its an issue I’m very curious about, so it seemed worth asking :)
Essentially for something to be decentralised and not ephemeral, everyone needs a copy of the data.
To go into a bit more detail—one of the biggest benefits of decentralised systems is generally redundancy has to be built in otherwise you have a Single Point Of Failure™️, and then you get data loss when it’s gone. Given any sensible decentralised system is designed to avoid this scenario, that data has to be somewhere, and generally the simplest and less expensive (in terms of processing) way to improve on data in one place, is to have it in every place. Any time the data isn’t in one place or every place, you then have an exercise in figuring out where it actually is. This “finding it” processing is going to take time and effort, and if you imagine a standard semi-popular lemmy post, that’s potentially data coming from all sorts of different places, which may or may not be there—this would inevitably make request times ridiculous and basically no one would use it.
At the end of the day, any kind of processing is energy, cost & time expensive, whereas storage makes that part of the process effectively instant and is much cheaper than increasing processing power in both cost and energy.
So basically in this use case and many like it: it makes sense if you’re trying to pick what to optimise, you optimise for lower processing and higher storage requirements rather than vice versa.
The history aspect is more straightforward to understand given the above, if you expect people to care what happened a year ago and want to support that, that data needs to live somewhere
