Actually Bitcoin keeps moving the goalposts. First it's a currency, next it's a trustless auditable log. All I need for trustless is auditability. All I need for auditability is a public Merkle Tree. I fail to see what actual real world value the PoW and associated approaches actually add.

Okay.

If you have a rebuttal, let's see it. Mockery is childish.

Still waiting for your rebuttal first.

There is nothing "trustless". Our world is social by structure, all our actions contribute to various kinds of trust. Blockchains aren't trustless they're just unable to internally express trust relationship: there is always trust in the devs, in the exchanges, in the miners, in the other holders. There are political events like "blockchain forks", protocol upgrade, parameter changes..

So much for the trustless auditable log. Btw "auditable log" is easy (eg certificate transparency), the hard part is deciding what goes in it.

Having said that you always trust something, you better do it consciously and run some real consensus algorithm like raft or stellar consensus protocol.
