# 🔍 Core Concepts

### Overview

Core concepts explain the building blocks of Fairway’s decentralized compliance infrastructure.

They are chain-agnostic in design, but tailored to **Cardano, Midnight, and EVM** in implementation.

Concepts:

* [Identity proofs (Cardano)](https://docs.fairway.global/~/revisions/65lkfXxYSTHA07mfx5hu/developers/core-concepts/identity-proofs-cardano)
* [Identity proofs (EVM)](https://docs.fairway.global/~/revisions/65lkfXxYSTHA07mfx5hu/developers/core-concepts/identity-proofs-evm)
* [Zero-Knowledge Proofs (Midnight)](https://fairway.gitbook.io/docs/~/revisions/T7QbPummS3rtxio8EvUm/getting-started/core-concepts/zero-knowledge-proofs-midnight)
* [Decentralized vaults](https://docs.fairway.global/~/revisions/65lkfXxYSTHA07mfx5hu/developers/core-concepts/decentralized-vaults)
* [Trust registries](https://docs.fairway.global/~/revisions/65lkfXxYSTHA07mfx5hu/developers/core-concepts/trust-registries)
* [Revocation Epochs & Freshness](https://docs.fairway.global/~/revisions/65lkfXxYSTHA07mfx5hu/developers/core-concepts/revocation-epochs-and-freshness)
