Sybil resistance

Proof of work provides Sybil resistance by requiring computational cost to gain block-producing rights.工作量证明通过要求计算成本来获得出块权，从而提供女巫攻击抵抗能力。

Sybil resistance ensures that creating many fake identities does not give an attacker disproportionate network influence.女巫攻击抵抗能力可确保创建大量虚假身份不会赋予攻击者与其不成比例的网络影响力。
