Indeed! Trust is a precious good in society and economy.

In Dec 1960 we "decentralised communication", now called The Internet. Bittorrent decentralised broadcasting, leading to streaming revolution. Bitcoin pioneered decentralised money.

At Delft University I've worked for 25 years to decentralised trust, democracy, and economic cooperation in general. As an academic this focus on running code and societal change obviously kills you career protects. See my writing from prior century on "Open Information Pools" (pre-wikipedia era) [0]. Essentially what others called the Global Brain.

We deployed a decentralised trust algorithm based on the interaction graph to 94k people, see [1]. Theoretical foundations are based on proving that the Harvard impossibility result against Sybil attacks made too strict assumptions, [2]. Leading to trust scores with resilience against fake identities: MeritRank [3]. This is being released in first version in this Tribler version. So hopefully this trust framework will help stop spammers a bit. We now pioneered "Decentralised AI", that critically relies on such a trust framework to function in a trustworthy manner [4].
