# Digital identity

GLOSSARY · BLOCKCHAIN & WEB3

Unique representation of a person in the blockchain ecosystem, based on verifiable wallets and credentials.

WHAT IS IT? · FOR DUMMIES

Your digital identity in the crypto world is like a virtual card.

You don't need to show your real name or a photo: your wallet, your tokens, your NFTs and your blockchain history speak for you.

Just as in the real world you use an ID or passport, in Web3 you can have an identity based on your address, your interactions and your achievements.

It allows you to show who you are without revealing personal details.

WHAT IS IT? · PRO

Digital identity in Web3 environments is a structured, verifiable and self-sovereign representation of an individual or entity, composed of elements such as the wallet address, **verifiable credentials (VCs)**, **Reputable NFTs**, **ENS (Ethereum Name Service)**, **DIDs (Decentralized Identifiers)** and in some cases, **Soulbound Tokens (SBTs)**.

Unlike Web2 systems based on centralized accounts and servers, digital identity in Web3 is built on blockchain and decentralized identity standards, where control lies with the user himself (self-sovereign identity).

This identity allows you to demonstrate achievements, memberships, credit history or reputation without exposing private information, as it is backed up by verifiable cryptographic signatures.

Technologies such as **DID + VC** (from the W3C), **ENS for legible names**, and SBTs (non-transferable tokens linked to identity) make it possible to compose a robust and transparent digital profile. In addition, this identity can evolve dynamically over time, allowing reputations to be built within communities, DAOs, DeFi platforms, or Web3 gaming ecosystems.

Digital identity is also key to voting systems, access to exclusive content, cross-chain interoperability, and regulatory compliance (KYC/KYB) without compromising user privacy.

Its correct implementation improves the user experience, enhances trust between anonymous parties and unlocks new layers of functionality on decentralized platforms.

However, it still faces challenges such as global standardization, the protection of sensitive data, portability between protocols, and resistance to censorship.

## 01 / Key points

- It's your digital “me” within the blockchain ecosystem
- It does not require personal data; it is based on wallet, tokens and chain activity
- It is built with technologies such as ENS, DIDs, VCs and SBTs
- It's self-sovereign: you control your data, not a centralized company
- Key to reputation, access, verification and governance in Web3

## 02 / Advantages

- **Privacy by Design**: you can prove things without revealing personal information
- **Cross-platform interoperability**: your identity moves with you between dApps
- **Full user ownership**: you decide what to show, share or keep
- **Verifiable reputation** in communities, DAOs and financial services
- **Friction reduction** in onboarding, access to content and user validation

## 03 / Disadvantages

- **Still under development**: standardization and mass adoption are lacking
- **Data correlation risk** if multiple elements are used in a chain
- **Technical complexity** for users not familiar with wallets or VCs
- **Difficulty recovering** if access to the wallet is lost
- **Legal and Ethical Issues** on portability, control and the right to be forgotten
