What do you mean? Almost all git projects have a general consensus on what the code looks like. This concencensus is not immediate (eg. at any given point in time, different nodes may have a different view of the repository), but over time nodes tend to converge on a single "true" history. When this does not happen, we have what is called a "fork", which also occurs in blockchain based cryptocurrencies. Put another way, every clone of the Linux repository agrees on what the kernel looked like at some point in the past (and all prior points which are recorded by git); however there is no central authority asserting this history.
