Digital Identity, Wallet Addresses, and ENS
A wallet can serve as an entry point for Web3 identity and permission management. A seed phrase must remain secret, while a public address supports contact and transaction lookup, and ENS gives addresses easier-to-remember names.
Wallet Identity and Private Credentials
The lesson explores the possibility of users managing their own digital identities, with a wallet serving as the entry point. A Secret Recovery Phrase generates and restores keys associated with accounts, and anyone who possesses it may also control the wallet's assets. It should therefore be distinguished from contact information that can be shared publicly, recorded offline, and stored securely rather than handed to an intermediary.
Public Addresses Also Bring Transparency
A wallet address is a string of characters that identifies an account and allows others to transfer assets to it. A public blockchain also lets observers inspect related transaction records through a blockchain explorer. Before sharing an address, users should understand the relationship between this transparency and privacy instead of assuming that publishing an address exposes only an unrelated name.
Simplifying Contact with ENS
The Ethereum Name Service, or ENS, can associate an easy-to-remember name with a wallet address and other information, reducing the need to use a long string in every interaction. The lesson uses this naming tool to illustrate how digital identity may work while noting that questions such as how wallets can prove a unique natural person or connect to traditional identity systems remain under development.
