Ask HN: Is there a changelog equivalent for the U.S. government?

https://en.wikipedia.org/wiki/Federal_Register ?

Not specifically the government, but there is a github[0] for amendments to the Constitution.

In addition to the Federal Register someone else already mentioned, I hear there is a company working on blockchain as an immutable record of laws and other government documents. I don't remember the name.
