Effective crypto ecosystems thrive when incentive structures eliminate the need for selfish behavior. Well-designed protocols realign participant interests toward collective outcomes. Take vesting mechanisms: they can maintain liquidity while preventing dilution, creating conditions where long-term commitment becomes the rational choice rather than a sacrifice. When structural rewards favor patience and protocol loyalty over short-term extraction, communities naturally gravitate toward sustainable participation. This is how protocol design shifts from managing bad actors to making cooperation the path of least resistance.
