In the world of cryptocurrencies,

fairness often becomes a marketing slogan.
But Rails has conducted a serious engineering deconstruction of fairness.

It recognizes that absolute fairness based on physical time
cannot be achieved in distributed systems.
Therefore, it does not pursue this illusory goal, but instead:
aims for transparency of rules and immutability of results.

Acknowledging reality: it accepts the existence of delays,
and does not try to hide them.
This reflects honesty.

Designing rules:
It transforms fairness from a race against time,
into obedience to rules.
Its deterministic sorter
is a public,
tamper-proof rule manual.

Delivering trust:
Ultimately, the sense of fairness comes from predictable certainty.
You understand the rules and are confident they will be enforced strictly.
Even if you fall behind due to network delays,
you are losing to a public set of rules,
not to hidden black-box operations.

This is subtle. It may not give you better results,
but it provides a stable,
predictable decision-making environment.
In the financial sector,
predictability itself is a huge value.

Rails' practice teaches us:
True fairness
is not equal results,
but procedural justice.
