According to Lemmy Users: Blockchain was a grift, AI is a grift, Quantum computing will be a future grift. So according to you what new and emergent technologies are not / will not be a grift? (lemmy.ml)

Why does a blockchain have to be one big omni ledger? Why do users need more than one token in it? Blockchain could be used for login tokens for a website or for proof of ownership of software licenses.

Yeah it’s currently flawed and used beyond the scale it’s capable of for things it’s not really good for, that was my entire point. Now the tech is tainted and reviled because of the grift and no one wants to touch it and explore what it could be useful for.

If login tokens are stored on a public ledger replay attacks write themselves. Public or private, keeping every login token ever is a horrible audit mechanism and doesn’t scale well. At scale, speed to generate becomes a concern. Not at scale, something lighter is faster.

A normal database scales better than a license blockchain and doesn’t require extra computation to write. Audit logs and hashes prevent extra edits. License files signed by a central authority don’t require a database and the central authority is functionally equivalent albeit less expensive than a blockchain.

I am still interested in a good use for the tech. I have yet to see one that is genuine.
