That's Why I Say Git is an App on Block Chain

I find understanding blockchain technology from git a good way for progammers.

Programmers commit commits to the projects' networks via git just as the miners of blockchains (such as BitCoin or Ethereum) accounting blocks on the chains.
As well as blocks, commits are immutable with the protection of chained hash values (actually in git they are mutable if one executes git rebase -f or something, but it's impossible to complete it without others' notice).
git organizes every files of a commit in the form of Merkle tree, the same as the form transactions or states organized in a block.

Of course, there implements no consensus michanism and decentralized accounting/committing rights in git.
