How this going to work effectively is still a myth. Because the donar is paid upfront, and the donar agree for the organ transfer after his death. This could increase the chance of crime.
For example person A is rich and he has got good sum of money. Person B is poor and he agrees for the organ donation and gets upfront payment. Now person B is in the urge of transplantation for survival. By this time some people will intend to kill and take the organ. So, this isn't going to be more effective plan. If something offensive or controversial I'm sorry for that, nothing intentional. Human minds are built in such a way.
The idea is that for people becoming donors, there's close to zero risk. We are paying you to become a member and forget your on the list. Many fintech companies like Paypal/Coinbase have done the same. You then go and live your life. After death, your estate (family) would get paid out 2-3x whatever you were paid initially so in this case ($1500) which they can use for anything (funeral costs, cover daily expenses, etc) if the organ is viable and the transplant occurs. After death, hospitals would run your name to see if your in the system. Each hospital would have their own credentials and everyone can see logs of hospitals accessing the blockchain, but the donor and recipient names remain encrypted.
This is what makes what I am doing so expensive and why I will need the crypto/VC community to fund this. So if I pay 100 people $500 just to sign up and sell me the exclusive right to one kidney for example, and I sell that right to xyz insurance company or government healthcare system (europe) for $50k, 1 death covers 100 bets. The cypto/VC investors see their investment grow since margins are so big. And we fill a pressing need. Even if we account for the additional $1500 payout to the family after death, this expense is easily accounted for since I'm expecting the average member's lifespan to reach 30-50 years. Inflation will reduce their payout amount, and conservatively investing small sums in an index fund or AAA bond (gov or corporate bond) over 10 years would yield the amount needed and the rest would be profit.
Math
$50k Crypto/VC investment per 100 people, excluding additional expenses to keep the math simple
$500 per person
$1500 estate payout upon death and transplant
$50,000 average payout from insurance company payout to us
10% average return on the S&P500 from 1926 to 2018
18-25 years old average donor age up registration
30 year conservative projection of average life expectancy of each donor after registration
$50,000 - $50,000 (100 people) = $0
100 * $50,000 (insurance pays us) = $5,000,000
$49,500 invested in the S&P500 at a conservative 4% expected return over 10 years with zero additional contributions = $23,770 profit
$49,500 invested in the S&P500 at 10% expected return over 10 years with zero additional contributions = $78,890 profit
$49,500 invested in the S&P500 at a conservative 4% expected return over 30 years with zero additional contributions = $111,048 profit
$49,500 invested in the S&P500 at 10% expected return over 30 years with zero additional contributions = $814,245 profit
Insurance company's projected profits per term policy, assuming $1000 initial investment and $200 monthly contribution over 30 years at 10% return = $398,935
Starting amount - $1,000
Total contribution (monthly fee paid by policy holder) - $72,000
Total investment - $471,935
