Beacons in tracking refer to tools or systems that help monitor and record the movement and interactions of users with specific assets or services. In the realm of blockchain, these beacons can be smart contracts or protocols that provide real-time data on transactions and user activity.

When a user interacts with a cryptocurrency wallet or decentralized application, beacons can send signals or notifications that update the state of a transaction. This enables better transparency and tracking of assets as they move through the network.

Additionally, beacons can serve to notify users about important events, such as price changes or security alerts. They help improve user engagement and ensure that participants are aware of relevant information in real-time. Overall, beacons enhance the tracking capabilities within cryptocurrency systems, making the experience more efficient and user-friendly.
