What is

Доказательства с нулевым разглашением (ZK)?

ZK‑доказательства позволяют доказать утверждение, не раскрывая исходные данные (секрет, баланс, личность).

Доказательства с нулевым разглашением (zero‑knowledge proofs) — класс криптографических протоколов, которые показывают истинность утверждения без раскрытия деталей. Это основа для приватных транзакций, выборочного раскрытия и приватных смарт‑контрактов. Важно различать конкретные схемы: у них разные требования, доверенные настройки и ограничения.

Key Points

  • Доказывает факт без раскрытия данных
  • Основа для приватности и выборочного раскрытия
  • Разные схемы имеют разные компромиссы (trusted setup, сложность)
  • Применяется в приватных приложениях и идентификации

Use Cases

1

Приватные транзакции и микширование

2

Выборочное раскрытие (например, соответствие требованиям)

3

Приватные голосования и доказуемая анонимность

What is ErgoMixer and how does it work?

ErgoMixer is a non-custodial, trustless mixing service that breaks the link between your input and output addresses. It uses Sigma Protocols to prove you're entitled to withdraw without revealing which deposit was yours. Unlike centralized mixers, there's no trusted party who could steal funds or keep logs.

Is Ergo better than Monero for privacy?

Different privacy models for different needs. Monero provides always-on, protocol-level privacy with ring signatures. Ergo offers optional privacy via Sigma Protocols with selective disclosure - you can prove things about data without revealing the data. Ergo excels at programmable privacy (private smart contracts), while Monero excels at simple private transfers.
