Global table of constants

Tezos provides a feature that lets user store data in a global table of constants. This makes it possible to reuse code or data between contracts, and by doing so, reducing the size of these contracts. It is a write-only key-value store, where anyone can add data as long as they pay for the storage costs. When you register a piece of data in this table, you obtain its address, which is a Base58-encoded Blake2b hash of the binary serialization of the data.

The data can then be referenced anywhere in your code. It can be used to store code, types, or data.
