According to CoinDesk, Lightning Labs developer Joost Jager plans to develop a new feature keysend for the Lightning Network, which can help Bitcoin achieve inheritance. It is reported that the keysend function will set a button for the user, which is tied to the communication service. Pressing the button every week can send related information to indicate the user status. If the button is not pressed for one week, it means that the Bitcoin user has passed away. The button will automatically use the communication service to send account-related information to the user's heir, which will help the heir inherit the Bitcoin.
