+In the following chapters you will find practical examples of several operations on blocks.

 ## Initialization with the default block
 
-(todo)
+In **`MultiTest`**, the chain is initialized with a default block that has the following properties:
+
+- `height{:rust}`: **12345**,
+- `time{:rust}`: **1571797419879305533** (Wed Oct 23 2019 02:23:39 GMT+0000),
+- `chain_id{:rust}`: **cosmos-testnet-14002**.
 
-- `App::default{:rust}`
-- `app.block_info{:rust}`
+These properties constitute the [BlockInfo] structure, which is defined in the CosmWasm library for
+representing block metadata. [BlockInfo] can be retrieved at any point in a test by calling the
+[`block_info(){:rust}`][block_info] function provided by `App{:rust}`.
