There are two reasons we have checksums:

  1. to verify database integrity. when you write a file into the
     repository, the checksum is recorded. when you read the file
     later on, the repository automatically checks to see if the file
     has the same checksum.

  2. to verify network transmissions. when a file is sent over
     the network, and checksum is also sent as a server-generated
     'property', so the client can verify it. the client stores it
     in the entries file. You can see it if you run 'svn info file'.
