<h1>FLO Standard Operations</h1>
<p style="max-width: 100%;">
RanchiMall is releasing FLO Standard Operations in order to make it easier for everyone in community to access common functions that any developer would need in a standardized way for JavaScript based development around FLO Blockchain ecosystem.
The methods enable developers to read and write into FLO Blockchain directly without any wallet or Chrome extension dependencies. They also enable developers to create digital signatures for any message out of any FLO ID, and functions verify them as well. In additional, standard methods are being provided for data encryption using recipient FLO ID and private key splitting using Shamir Secret Sharing algorithm.
We are also provding access to a common data infrastructure called the FLO Blockchain Data Cloud which can provide place for host data that will be too expensive to put inside the blockchain.
We are offering methods simplifying access to inbuilt browser database IndexedDB or IDB.
Last but not the least, we are also providing methods for simplying common operations for FLO based Distributed Application Development.
