+### Service Interface Design Pattern
+
+When creating or updating service interfaces and clients, follow this pattern to avoid exposing protobuf/gRPC types:
+
+**Interface Layer** (`Interface.go`):
+- Define interfaces using native Go types and existing domain types (e.g., `*PeerInfo`, `[]string`, `bool`, `error`)
+- Do NOT expose protobuf types (e.g., `*p2p_api.GetPeersResponse`) in interface signatures
+- Use simple, idiomatic Go return types: `error` for success/fail, `bool` for yes/no, `[]string` for lists
+- Prefer existing domain structs over creating new minimal types
+
+**Client Layer** (`Client.go`):
+- Keep the protobuf/gRPC import for internal use (e.g., `import "github.com/bsv-blockchain/teranode/services/p2p/p2p_api"`)
+- Maintain internal gRPC client field (e.g., `client p2p_api.PeerServiceClient`)
+- Public methods match the interface signatures (native types)
+- Convert between native types and protobuf types internally using helper functions
+
+**Benefits**:
+- Cleaner API boundaries between services
+- Reduces coupling to gRPC implementation details
+- Makes interfaces more testable (no protobuf dependencies needed for mocks)
+- Uses idiomatic Go types that are easier to work with
+
+**Example**:
+```go
+// Interface.go - Clean, no protobuf types
+type ClientI interface {
+    GetPeers(ctx context.Context) ([]*PeerInfo, error)
+    BanPeer(ctx context.Context, peerID string, duration int64, reason string) error
+    IsBanned(ctx context.Context, peerID string) (bool, error)
+    ListBanned(ctx context.Context) ([]string, error)
+}
+
+// Client.go - Internal conversion
+type Client struct {
+    client p2p_api.PeerServiceClient // gRPC client
+}
+
+func (c *Client) GetPeers(ctx context.Context) ([]*PeerInfo, error) {
+    resp, err := c.client.GetPeers(ctx, &emptypb.Empty{})
+    if err != nil {
+        return nil, err
+    }
+    // Convert p2p_api types to native PeerInfo
+    return convertFromAPIResponse(resp), nil
+}
+```
