No, git uses a merkle tree, which the blockchain also uses. That’s the only similarity. It doesn’t rely on a massively distributed system to get the next time stamp for the next commit. Git is decentralised, not distributed. You get the whole git database (for want of a better word) when you clone it, unless you use the —unshallow option. git does not implement a block-chain.
