So who rewards those who store forum data on the sidechain?
so if the bitcointalk forum was running on a sidechain, people could be required to use a native token to pay to post. the native token would have been bought using bitcoin.
I'm sure it's possible to build such system, but how many people willing to pay for that?
https://stacker.news/ has somewhat similar system, but with limited success.
yes data compression could be useful but it does have costs. the cost is in terms of compressing and then everyone that wants to read it has to decompress it. so it uses energy.
That's true, you can't get everything. But at least you just need to decompress it once.
