What does the chain part provide that's not available right now through any page with an interledger link in meta and maybe an .eth link if you want to be fancy with anticensorship?
Lol! It’s not my intention for this to be a get rich quick scheme but there are running costs (user registration and TheGraph network payments). If the platform is to be self sustaining it needs to cover its costs.
Is there a reasonable long term platform fee that you would find acceptable? Say 1% or 0.1%?
Only in the short term. TheGraph is migrating from a centralised service to a decentralised network and the community can run alternative oauth servers to help mitigate attacks. I'm no cybersecurity specialist though.
Also, the data is always available on-chain and the protocol is open so other people can write an alternative ui with their own blockchain query capabilities. Like Bress.xyz does with Mirror.xyz.
