A Decentralized Identifier (DID) is a new type of identifier defined by the World Wide Web Consortium (W3C) that enables verifiable, digital identities. DIDs are fully under the control of the DID owner, independent from any centralized registry, identity provider, or certificate authority.

# Price Oracles

_(Requires the [PriceOracle amendment][])_
|
||||
Price oracles gather real-world market prices and record them in the blockchain so that other tools and technology can access this data directly.
|
||||
|
||||
Blockchains can't inherently interact with and "know" what's happening off the network, but many of its use cases in decentralized finance require this information.
|
||||
|
||||
Price oracles solve this problem. An oracle is a service or technology that gathers real-world information, such as market prices, exchange rates, or interest rates, and relays it to the blockchain. Like blockchains, most oracles are also decentralized and validate data through multiple nodes.

Blockchains can't inherently interact with and "know" what's happening off the network, but many of its use cases in decentralized finance require this information. Price oracles solve this problem by putting the data on-chain where decentralized apps can find it. Like blockchains, most oracles are also decentralized and validate data through multiple nodes.

Generally speaking, oracles aren't limited to only providing financial information. They can provide any type of info, such as what sports team won a game, or even the weather. The XRP Ledger's Price Oracle feature, however, is designed specifically for reporting the prices of assets.
