In section 3.Timestamp Server of the Bitcoin whitepaper it says:
The solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post
I am confused by the meaning of the sentence in regards to "widely publishing the hash". I am not sure if the correct way to interpret this is, the seed / genesis block should be widely published or that a function of the server is to repeatedly publish each block that gets timestamped.
