# DHT Records

DHT records are key–value pairs that are stored in a DHT, and any participating node can efficiently retrieve the value associated with a given key without a centralized server. Meaning, it's a decentralized and distributed database.

***

#### **DHT Records** are the individual pieces of data stored in this distributed table. Each record typically consists of:

* **Key:**\
  A unique identifier (usually a hash or byte string) used to locate the record in the DHT.
* **Value:**\
  The actual data or information associated with the key.
* **Subkey (optional):**\
  A secondary key that allows more granular addressing or versioning inside the main key.
* **Expiration Time:**\
  A timestamp indicating when this record becomes stale or invalid, ensuring the network eventually removes outdated information.

Do not use special characters, or even slashes, etc., as keys or subkeys without testing.
