経済学の行動理論から外れていた日本

ブロックチェーンが発明される遥か前より日本の商取引には同じシステムが存在していました。『評判どう？』という一言があらゆる商品、サービス、企業、人物に対するチェックシステムになっており、その一言があらゆる記録へのアクセスを保障してくれていたのです。また、何かしら問題があった商品、サービス、企業、人物は即座にチェーンから外されてしまうため、『いい評判』の維持は日本人にとって死活問題でもあったわけです。
しかし、今もなお、この村社会(相互監視)システムが過剰に働いているからこそ日本では『アイツいいヤツだから』とか『長い付き合いだから』などだけの理由で、能力や商品価値を度外視して雇用や取引が成立してしまうのです。経済学的には事実上のcorruption(腐敗)やnepotism(縁故)
であり、経済的には損失が大きいのです。

Long before Block Chain was invented, the Japanese already had a similar credit system called "Hyoban" that involved everyone within its economic society.

Hyoban=Reputation+Credit

As Japanese would call it "Ears on the wall, eyes everywhere", people were constantly watched over and rumoured by everyone else. For centuries and even now the most valuable asset to anyone in Japan is "Hyoban".

Some academics would bring on  the contrast between Japan's shame culture vs. Western sin culture to this notion, but shame culture is a fundamental protocol that can be found in other animals and it's a basic common culture to any civilization. However the Japanese were among the first to utilize shame culture into economic activities.

Just as feudal samurai would cut their gut out to protect his Hyoban, most Japanese in modern Japan would do everything to build and protect and promote this valuable asset.

The downfall is that this system would occasionally be skewed to and weighed on evaluating individual personalities that probably had nothing to do with his or her real financial credit.

People in Japan choose to give someone tasks and money just because he or she likes the person's personalities.
