# Function create_checkpoint_end_marker

Module: `noir_aztec::protocol::blob_data`

```rust
pub fn create_checkpoint_end_marker(num_blob_fields: u32) -> Field
```

Create the field that marks the end of a checkpoint. It's a concatenation of: `CHECKPOINT_END_PREFIX` | `num_blob_fields`

`CHECKPOINT_END_PREFIX` occupies the bytes up to the point where `num_blob_fields` begins. `num_blob_fields` occupies 4 bytes.
