State is a package for managing state.
Cells are compare-and-swap cells. They support reading and compare-and-swapping the data.
Content-addressed data stores identify pieces of data by their hash. Posting to the store returns the hash of the data, which can be used later to retrieve the data, and verify that it is correct.
Interfaces for Key-Value and transactional Key-Value stores are defined at state.KVStore and state.KVStoreTx.
Interfaces and utility functions for dealing with filesystems as defined by POSIX.
