For this example, we have a dead-simple `Tx` type that contains the `MsgSend` and is JSON decoded:

In this first application, we won't have any authentication at all. This might

make sense in a private network where access is controlled by alternative means,
|
||||||
|
like client-side TLS certificates, but in general, we'll want to bake the authentication
|
||||||
|
right into our state machine. We'll use `Tx` to do that
|
||||||
|
in the next app. For now, the `Tx` just embeds `MsgSend` and uses JSON:

Thus, transactions in this blockchain are expected to be JSON encoded `MsgSend`.
