|
|
The Cosmos Hub holds all of its state in a Merkle store. Updates to
|
|
|
|
|
the store may be made during transactions and at the beginning and end of every
|
|
|
|
|
block.
|
|
|
|
|
|
|
|
|
|
While the first implementation of the Cosmos Hub is built using the Cosmos-SDK,
|
|
|
|
|
these specifications aim to be independent of any implementation details. That
|
|
|
|
|
said, they provide a detailed resource for understanding the Cosmos-SDK.
