# ResQ.Core.BlockchainEvent

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

## BlockchainEvent Class

Represents a blockchain event for immutable logging.

```csharp theme={null}
public record BlockchainEvent : System.IEquatable<ResQ.Core.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.Core.BlockchainEvent.md "ResQ.Core.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 = BlockchainEventType.IncidentDetected,
    Location = new Location(37.7749, -122.4194),
    EvidenceCid = "Qmabc123...",
    Metadata = new Dictionary<string, object>
    {
        ["incidentId"] = "inc-001",
        ["severity"] = "High"
    }
};
```

### Remarks

Blockchain events provide tamper-proof records of system activities.
They can include metadata and links to off-chain evidence.
