(Continuation from yesterday)

This time, I had to do a "relay race" to collect family register of deceased father, from a city hall to another city hall.

If "black-chain" consolidates our records of birth and moving, we will not have to do the stupid "traveling salesman problem".

According to the system of "officially registered seal", I am impressed that "why this system work well".

For example, it is possible to make a "fake seal". In order to get "seal registration certificate", we can ask someone to make a "fake driver's license".

(An administrative institution might have an inquiry system by the driver's license number)

However, the way to proof of "I am what I am" is guaranteed by the "complex procedures" after all.

As ID system, it is better to use a DNA identification device using finger sweat and fingerprint/

For my mother in bed without a toe to the floor, I will get her ID by the above process and send it to bank. It will be enough.

For succession and insurance, if we can get methods and certificates that are guaranteed by non-rewrite, the protocol works will be perished from banks.

This means, not only for banks, but also for city halls

"At this rate, an city hall will be an application of smartphones"

might be coming soon.

Actually, convenience stores are used instead of government offices by My Number card.

This time, I got all the necessary documents (stamp certificate, family register, resident card) on inheritance at a late-night convenience store near my parents house.

It is scary just thinking that "I must get back to the city office at my home residence".
