First, for all of this you need strong KYC. People register their BTC addresses and balances. Going in the regular insurance business and fraud detection. Basically, fraudsters need to know they are on a risky hook to pay or lot or even go to prison. For example, if someone tells you, "access to BTC address lost", these coins may never ever be moved again from that claimed to lost address. Because if they are, it's insurance fraud. You'd then have to go through the legal system like any insurance does.
We are in progress of discussion KYC with our legal advisor. It is a good tool to prevent some types of fraud. But, it also may scare a lot of crypto economy members who care about their anonymity.
So KYC discussion in progress, welcome)
Registration of BTC/ETH addresses and balances not so easy task. Imagine you hold some BTC in Coinbase. Do you know what address they have exactly? And if you a trader, your balance can change very often so it can be very different at the end of the insurance policy from when you insure it. Anyway, we hope our legal advisor and all of you will help us to find the optimal decision of how must Inchain prevent possible fraud.
For now we plan do not check the address and balance of insured before insure him. We think if someone ready to pay an insurance premium for 100 BTC he really may insure it.
In the event of damage, you should probably terminate the contract with the customer. (But of course still restore the customers damage if it was legit.) Not nice - but many insurance companies do that, no?
Yes, we think that not more that only one insurance payment possible during an insurance policy lifecycle.
Stolen coins are of course more difficult. Any worthy amount... Could you work with the authorities and track them down?
We intend to continue a promotion of Inchain concept to real insurance sector. But it needs a lot of time. When we will have the PoC of Inchain it may speed up a process legitimisation of Inchain. Of course, if Inchain will act as a fully regulated company there will be available all legitimate tools for protecting of Inchain customers.
