Git is a real-life use-case

Git is not a blockchain. Most importantly, it's not distributed. There's a singular git server that all git clients for that repository connect to and use as a source of truth.

[–] [email protected] 10 points 4 months ago

Git was built specifically to avoid the necessity to have one authoritative server.

I agree it's not a blockchain, (although it has chain properties) but it is kinda decentralized. By convention projects almost exclusively have a single remote, and by convention that single remote is treated as an ultimate source-of-truth... But you can absolutely have the same repo with multiple remotes defined, and one could establish different schemes to determine which branches on which remotes represent what in terms of "truth".

I've pulled code branches between my computers without publishing to an external server plenty of times. It's a really useful feature to be able to keep stuff in sync with a version history.

In contrast with Centralized Version Control Systems (CVCSs), the distributed nature of Git allows you to be far more flexible in how developers collaborate on projects. In centralized systems, every developer is a node working more or less equally with a central hub. In Git, however, every developer is potentially both a node and a hub; that is, every developer can both contribute code to other repositories and maintain a public repository on which others can base their work and which they can contribute to.

That is patently false. It was developed to help develop the Linux kernel, which famously has multiple decentralized repositories managed by different maintainers.

The fact that most companies use it in a way you describe, with only one central repository, does not mean that git is not distributed.

Counterpoint: it is a chain and there absolutely is not one server.
