Apart from those already explained, what is the other uses of CRF tokens?
As I know CRF Token is also used for a Agent verification on the platform, when the fee for such verification is paid by CRF tokens and personal information about verified agent or user (his or her controlled personal Ethereum address) records to the blockchain.
How to find out whether it has been verified or not at the time of registration?
Verified users will be able to prove their verified digital identity within the CrowdForce Platform by signing a message from privately controlled Ethereum address and smart contract integrated to the ecosystem.
To avoid failure or double recording in agent data recording, does CrowdForce have certain steps to anticipate it?
CrowdForce company requests personal data for the Verification and during the first stage of development will record to the smart contract only a hash function result of a set of verification documents and the Agent data is stored highly securely in a centralized database. In Phase 2 of our roadmap, CrowdForce plans to record Verified Agents data hashed function results to the Ethereum blockchain by batches, but store actual users data (scans, sensitive personal data) in a blockchain-based storage network like Storj , Filecoin or another equivalent blockchain. That's all I know.
