The uniqueness of the Ethereum addresses and private keys

Ethereum decentralized network is strongly based on cryptographic techniques to protect transactions and manage users’ identities. A crucial aspect of this security is the univocal representation of the user’s addresses and private keys. In this article, we will deepen the details of as Metamask (a popular Ethereum portfolio) uses Mac addresses for uniqueness and we will explore if your private ethereum key can be mapped with the address of another user in the Polygon network.

The process of generation of the address

To understand why the Ethereum addresses are unique, we examine the process. Each Ethereum account is represented by a pair of public-private keys:

* Public key : a 65 -character hexadecimal string (PrivateKy) that acts as an account address.

* Private key

: a large number, randomly generated (publickey) used to sign transactions.

UNIFICITY address

As you said, the uniqueness of the addresses depends on the uniqueness of the private keys. In other words, if two different private keys are combined with the same public key, they will produce the same address. This is a fundamental principle of Ethereum security architecture.

For example:

* Private key : 0x1234567890Abcdef

* Public key : 0x1234567890ABCDEF (equal to above)

* Address : 0x1234567890ABCDEF-0X1234567890ABCDEF

As you can see, the same private key generates two different addresses. This guarantees that the address of each user’s account is unique and cannot be easily guessed or replicated.

Metamask: using Mac addresses for uniqueness

Metamask uses a technique called “Mac (message authentication code)” to ensure uniqueness of the address. A Mac is a digital imprint generated by the sender’s public key, by the payload of messages and the timestamp. This guarantees that even if an attacker intercepts and modifies the message (i.e. transactions data), will not be able to forge the original signature.

In Metamask, when creating a new account or transfer funds, use Mac addresses as a unique identifier for each address. When you receive transactions from another user, Metamask generates a Mac with a public key and the recipient’s public key. This guarantees that even if two users have the same private keys, their addresses will still be different.

The private key of Ethereum can correspond with the address of another Polygon user?

Now, let’s face a potential concern: can your private key Ethereum correspond with the address of another user in the Polygon network? In short, no. The reason is that Metamask and other portfolio services such as Metamask (The Ethereum Wallet) use Mac addresses to ensure uniqueness of the addresses.

When the resources on the Polygon network are transferred, you will have to authenticate using your pair of public-private keys, which includes both the Ethereum private key and a unique Mac address generated by Metamask. If these two values ​​correspond, it is considered a valid transaction, ensuring that only authorized accounts can access their funds.

In summary:

• Ethereum addresses are unique due to the uniqueness of private keys.

• Metamask uses Mac (message authentication code) to ensure uniqueness of the address.

• Your private key Ethereum will not correspond with the address of another user in the Polygon network, unless both wallet services will agree on a shared Mac code.

By understanding how metamask and other wallets such as Metamask work, you can appreciate the safety measures in place to protect your Ethereum resources. If you intend to transfer funds or access the sales of your accounts on the Polygon network, be sure to use the official metamask portfolio service with a valid private key and a Mac address.
