It's still missing important pieces. They both fall under the superset of "hash chain" / Merkle tree, but cryptocurrency blockchains are designed to deal with the possibility of bad actors. Git can't ensure trust, unless you PGP sign commits.

Git + PGP + some computationally expensive mechanism to broadcast verified PGP key attributions + a consensus algorithm might be a little bit like a blockchain, but I can't think of a good use case for that. Git repos generally aren't intended to be pushed to by the whole world.

A blockchain doesn't ensure trust either. The blockchain "trusts" whoever has the most powerful hash cracking array.

I should've said "attempt to ensure trust".

Incidentally, this is a problem I've worked on previously.
