What is Trust?

It's the relationship between entities that allow them to co-operate with each other.

For trust to be required, there must be vulnerability, as in chance that the counter party might cheat.

At the same time, for trust to exist, one must believe that the counter party has an incentive to co-operate instead of cheating.

If there is no vulnerability, there is no need for trust.

There are number of ways of creating tagged unions.

type X = { type: A, prop: number } | { type: B, prop: string };

type Y = { type: A, data: { prop: number } } | { type: B, data: { prop: string } };

type Z = ['A', { prop: number }] | ['B', { prop: string }];
