# ResQ.Blockchain.BlockchainEvent

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

## BlockchainEvent Class

Represents an event to be recorded on the blockchain for immutable logging.

```csharp theme={null}
public record BlockchainEvent : System.IEquatable<ResQ.Blockchain.BlockchainEvent>
```

Inheritance [System.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object "System.Object") → BlockchainEvent

Implements [System.IEquatable\<](https://learn.microsoft.com/en-us/dotnet/api/system.iequatable-1 "System.IEquatable`1")[BlockchainEvent](./ResQ.Blockchain.BlockchainEvent.md "ResQ.Blockchain.BlockchainEvent")[>](https://learn.microsoft.com/en-us/dotnet/api/system.iequatable-1 "System.IEquatable`1")

### Example

```csharp theme={null}
var evt = new BlockchainEvent(
    EventId: "evt-001",
    EventType: "IncidentDetected",
    Payload: "{\"incidentId\":\"inc-001\",\"severity\":\"High\"}",
    IpfsCid: "Qmabc123...",
    Timestamp: DateTimeOffset.UtcNow
);

var result = await neoClient.RecordEventAsync(evt);
```

### Remarks

Blockchain events provide an immutable audit trail of critical system activities.
Each event is assigned a unique ID and can optionally reference IPFS content
for additional evidence storage.
