+# Offnet Assets
+
+A blockchain asset recording and transfer system based on Hyperledger Fabric, supporting core functionalities such as bond issuance, token minting, and cross-chain recording.
+
+## Features
+
+- **Asset Recording**: Records of assets are stored persistently
+- **Cross-chain Operations**: Supports locking and synchronization of main chain/side chain
+- **Token System**: Supports HTL locking and cross-chain transfers
+- **Evidence Management**: Initialization, querying, and status tracking of evidence records
+
+## Quick Start
+
+### 9999
+func (w *Watcher) Close() error
+func (w *Watcher) Add(name string) error
+func (w *Watcher) Remove(name string) error
+type watch struct
+func (w *Watcher) readEvents()
+func (e *Event) ignoreLinux(mask uint32) bool
+func newEvent(name string, mask uint32) Event
