# Blocks

#### Validity <a href="#validity" id="validity"></a>

* **Valid:** Indicates that the block contents have been verified and deemed correct according to protocol rules.
* **Invalid:** Indicates that the block contents violate protocol rules and are therefore rejected. All transactions within this block are considered invalid and will be dropped.
* **Empty:** Indicates that the block contains no transactions.

#### Status <a href="#status" id="status"></a>

* **Proving:** The block has been submitted successfully and is currently undergoing verification to confirm its correctness.
* **Completed:** The block’s validity has been determined. If valid, it will be labeled as Valid under the “Validity” field; if not, it will be marked as Invalid.

#### Block type <a href="#block-type" id="block-type"></a>

* **Type 0:** A block containing no user transactions. These blocks are typically executed to reflect deposit actions automatically.
* **Type 1:** A block that includes the first-ever transaction from a sender's address. This special block type is used for a sender’s initial on-chain activity.
* **Type 2:** A block that includes a subsequent transaction from a sender's address (i.e., not their first). Compared to Type 1, transactions in a Type 2 block are executed with lower fees, making repeated transactions more cost-efficient.

#### Blocks List <a href="#blocks-list" id="blocks-list"></a>

Displays a real-time paginated list of blocks, including:

* Height (block number)
* Hash
* Timestamp
* Number of transactions
* Validity
* Status

#### Block Details <a href="#block-details" id="block-details"></a>

Provides detailed block-level information such as:

* Status and timestamp
* Block producer’s address
* Block validity proof (ZKP)

This helps users and Block Builders confirm whether a specific block was posted successfully.
