Once you've created your wallet, your public address (also known as your public key) serves as the identifier for all transactions linked to your account. Much like a bank account number, this address is a unique alphanumeric string representing your blockchain account.
A typical public wallet address appears as follows:
0xd8da6bf26964af9d7eed9e03
Sharing Your Public Address
You can safely share your public address, but be aware that anyone can view its full transaction history by searching it on a blockchain explorer (e.g., Etherscan). While memorizing this lengthy string is possible, tools like the Ethereum Name Service (ENS) simplify the process. ENS lets you register a .eth domain (e.g., vitalik.eth) and link it to your wallet, replacing the complex address with a human-readable name.
Key features of ENS:
- Uniqueness: Each .eth name is one-of-a-kind (e.g., only one
vitalik.ethexists). - Transferability: Ownership can be sold or transferred.
- Versatility: Works for wallet addresses, websites, and domains.
Digital Identity in Web3
Major organizations—from tech giants like IBM and Microsoft to global bodies like the W3C—are exploring ways to integrate Web3 with traditional identity systems (e.g., passports, voting, social security). Innovators in the Ethereum ecosystem, such as Consensys, are also contributing to this evolution.
Key Research Questions in Digital Identity
The future of online identity is being shaped by critical questions, including:
👉 How does blockchain enhance identity security?
👉 What role do decentralized identifiers (DIDs) play?
FAQs
Q: Is my public wallet address private?
A: No—it’s publicly visible on the blockchain, but only you control access to the wallet via your private key.
Q: Can someone steal my funds if they know my public address?
A: No. Funds can only be moved with your private key, which should never be shared.
Q: Why use ENS instead of a regular wallet address?
A: ENS names are easier to remember, share, and verify, reducing errors in transactions.
Q: How is Web3 identity different from traditional systems?
A: Web3 prioritizes user control and decentralization, unlike centralized databases managed by institutions.
