We now have introduced you a listing of three Blockchain Oracles which might be each quick and safe. They’ll maintain your knowledge protected and ship new info at blazing-fast speeds.

QED is a blockchain oracle that fulfills the necessities of security and velocity. The decentralized oracle is constructed to reward nodes with better historic accuracy, guaranteeing environment friendly knowledge supply. 

Additional, the Oracle Community relies on arduous exterior collateral, which eliminates systemic threat. It signifies that there might be no “financial institution run”(a sudden rush to promote cash and get out of the community) even when crypto costs fall.

Their main focus is on the know-how of the oracle and creating it based mostly on group inputs. 

The protocol relies on the Cosmos SDK and has its Blockchain known as the Band Chain. It has a mean response price of 6 seconds. 

Nevertheless, it has an inbuilt token that exposes it to a level of systemic threat.


Blockchain Oracles are the hidden mechanism which makes Web3 as safe as you see right this moment. Any defective oracle could cause losses in hundreds of thousands or billions. A correctly blockchain oracle delivers knowledge securely on good contracts and makes certain that the information is correct and well timed. 

We now have listed three blockchain oracles which might be every distinctive in their very own respect. QED is the quickest and has by no means been hacked. API3 eradicated the necessity for third events and straight let good contracts entry off-chain knowledge. And eventually, the Band Protocol has multi-chain performance. All three entry and switch knowledge in a quick, environment friendly and safe method.
