Top 18 Crypto Oracles Services
- DLT networks and smart contracts can in general not access important data from outside of the blockchain ecosystem. In order to execute some code a smart contract needs input via data and access to information from outside of the blockchain world (the traditional centralized world). This information is important to the contractual agreement, in the form of electronic data. Here come the oracles into the game. Oracles are in general services that send, execute and verify data from the centralized world and submit this information to smart contracts, triggering state changes on the DLT network.

Different types of Oracles?
- Oracles forward external data or information to trigger the predefined rules of a smart contract. This external data comes either from so ware (Big-data application) or a physical hardware (IoT). That could be any data, like weather temperature, successful payment, data changes or price fluctuations. The smart contract is calling data from the traditional world. This induces network transaction costs. In the case of ETH, this would be “gas.”
- Software based Oracles
These crypto oracles rely on data that originates from online sources, like temperature, price movements, sentiment data and flight delays. The oracle listens for the input and pushes it into the smart-contract. - Hardware based Oracles
There are also some crypto oracles that need data from the physical world. A person is crossing a barrier where movement sensors detect ther person and send the new information to a smart-contract, or RFID sensors in the supply chain ecosystem. That is a fascinating industry. - Inbound bases Oracles
These blockchain oracles provide data from the real world. - Outbound based Oracles
These blockchain oracles turn the data flow reverse and send data from the blockchain world to the centralized world. - Consensus-based Oracles
These blockchain oracles get their data and information from human consensus and prediction markets. Examples here are Augur and Gnosis.
