# Active Entities

`GET /v1/metrics/entities/active_count`

**Definition.** The number of unique entities that were active either as a sender or receiver. Entities are defined as a cluster of addresses that are controlled by the same network entity and are estimated through advanced heuristics and Glassnode's proprietary clustering algorithms.\n\n**Technical.** Entities are clusters of addresses estimated to be controlled by the same actor, identified through advanced heuristics and Glassnode's proprietary clustering algorithms. Entity-based metrics rely on statistical and data-science methods that are refined over time. The series is therefore mutable: its established history is stable, but recent data points may revise as clustering improves. For methodology, see our [article on account-based metrics](https://insights.glassnode.com/account-based-metrics/).\n\n**Notes.** For more information, see our article on [how many entities hold Bitcoin](https://insights.glassnode.com/bitcoin_holders/).\n
