# ResQ.Blockchain.MockNeoClient.RecordEventAsync(ResQ.Blockchain.BlockchainEvent,System.Threading.CancellationToken)

### [ResQ.Blockchain](./ResQ.Blockchain.md "ResQ.Blockchain").[MockNeoClient](./ResQ.Blockchain.MockNeoClient.md "ResQ.Blockchain.MockNeoClient")

## MockNeoClient.RecordEventAsync(BlockchainEvent, CancellationToken) Method

Records a mock blockchain event in memory.

```csharp theme={null}
public System.Threading.Tasks.Task<ResQ.Blockchain.TransactionResult> RecordEventAsync(ResQ.Blockchain.BlockchainEvent evt, System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));
```

#### Parameters

<a name="ResQ.Blockchain.MockNeoClient.RecordEventAsync(ResQ.Blockchain.BlockchainEvent,System.Threading.CancellationToken).evt" />

`evt` [BlockchainEvent](./ResQ.Blockchain.BlockchainEvent.md "ResQ.Blockchain.BlockchainEvent")

The blockchain event to record.

<a name="ResQ.Blockchain.MockNeoClient.RecordEventAsync(ResQ.Blockchain.BlockchainEvent,System.Threading.CancellationToken).cancellationToken" />

`cancellationToken` [System.Threading.CancellationToken](https://learn.microsoft.com/en-us/dotnet/api/system.threading.cancellationtoken "System.Threading.CancellationToken")

Cancellation token for the operation.

Implements [RecordEventAsync(BlockchainEvent, CancellationToken)](./ResQ.Blockchain.INeoClient.RecordEventAsync\(ResQ.Blockchain.BlockchainEvent,System.Threading.CancellationToken\).md "ResQ.Blockchain.INeoClient.RecordEventAsync(ResQ.Blockchain.BlockchainEvent, System.Threading.CancellationToken)")

#### Returns

[System.Threading.Tasks.Task\<](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")[TransactionResult](./ResQ.Blockchain.TransactionResult.md "ResQ.Blockchain.TransactionResult")[>](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")\
A [TransactionResult](./ResQ.Blockchain.TransactionResult.md "ResQ.Blockchain.TransactionResult") with a generated transaction hash and confirmed status.

### Example

```csharp theme={null}
var evt = new BlockchainEvent(
    EventId: "evt-001",
    EventType: "IncidentDetected",
    Payload: "{\"incident\":\"inc-001\"}",
    IpfsCid: null,
    Timestamp: DateTimeOffset.UtcNow
);

var result = await mockClient.RecordEventAsync(evt);
// Logs: "MOCK: Recorded event evt-001 of type IncidentDetected, TxHash: 0x..."
```

### Remarks

This mock implementation:

* Generates a random transaction hash using cryptographic random bytes
* Increments the internal block height
* Stores the event in memory, indexed by incident ID if present in payload
* Logs the operation at Information level
