RedStone in crypto?
-------------------

In short RedStone is a new type of program that helps apps and smart contracts on different blockchain layers get information from reliable sources. It improves on previous systems and offers a better, faster, and more user-friendly solution for the DeFi ecosystem.

How does RedStone differ from others?
-------------------------------------

*   Speed-o-meter: Provides quick updates, eliminating the wait time for information.
    
*   Cost efficient: Saves money on gas by using a special connector that includes signed data packages in transactions.
    
*   Multitool: Allows smart contracts to access different types of information like volatility, order books, and trading volumes.
    
*   Accountable: Data provider's history is always accessible on Arweave, making sure they can be trusted.
    
*   Insurance: If there is downtime or incorrect data, the data provider's locked collateral will cover any losses, protecting those affected.
