Verification of messages signed on Ethereum networks
Ethereum is a decentralized platform that allows secure and transparent communication between users. One of its main features is the possibility of sending and receiving signed messages, also called contracts or transactions. Although the standard customer offers basic features to check the signed messages, it has not yet been implemented in the graphic user interface (Gui) for Ethereum networks.
Understand signed messages
A message signed on Ethereum implies the use of a digital signature, which is generated by the private key to the sender and the message itself. The digital signature guarantees that only the authorized part, that is to say the person who has sent the message, can access the original data. This feature offers a high level of safety and integrity to transactions.
Verification of messages signed in the standard customer
In the standard customer, signed messages can be checked using the Ethers.js library, which is the official packaging of JavaScript Ethereum. To check a signed message, you can use the following steps:
- Get the public address of the sender and the private key.
- Create a new transaction object with the signature field defined on “True”.
- Define the recipient’s address on the one who received the signed message.
- Use the
Ethers.js' library to sign the transaction using the sender's private key.
Here is an example of how you can check a message signed in the standard customer:
Javascript
Const Ethers = require ("Ethers");
// Get the public address and private key to the sender
CONSTE SENDERADDRESS = "0x ... Address of the sender ...";
Conste SenderPrivateKey = "0x ... Key deprived of the sender ...";
// Create a new transaction object with the signature field defined on True
Const tx = {
// ... Transaction data ...
Signature: True,
};
// defines the recipient address on the one who received the signed message
tx.Recipientaddress = "0x ... recipient address ...";
// Sign the transaction using the private key to the sender
Tx.sign = ethers.wallet.frombrivatekey (SenderPrivateKey);
// Check the signed message
Const verified = wait tx.sign ().
Return ethers.utils.Verifysignature (Signedtx, Senderaddress, Sender Privatekey);
});
'
In the graphical interface (not yet implemented)
The standard customer is a command line application and does not have a graphic user interface (GUI). Therefore, it cannot be used to check the messages signed in the traditional sense. However, some third -party tools and libraries can provide a way to interact with Ethereum networks from a graphical interface.
For example, you can use theWeb3 library.jsto create a web interface to interact with Ethereum nodes. This allows users to sign messages on their local machine and check them using the node validation service.
Conclusion
Although the signed messages have a leg implemented in the standard customer, there is no native way to check them in the graphical interface for Ethereum networks. However, third -party tools and libraries can provide a way to interact with Ethereum nodes from a graphical interface. To start, you can explore options such asWeb3.js` or” Ethers.js “, which and for web interfaces to interact with Ethereum Networks.
