Metamask: How do Ledger hardware wallet signatures differ from web3.eth.personal.sign?

Ledger Hardware Wallet Signatuurs vs web3.eth.personal.Sign: Deep Diving

When building a decentralized application (DAPP) in the Ethereum block chain, it is necessary to ensure the user authentication and identity verification. One common approach is the web3.eth.personal.sign () 'method of signing transactions based on the Ethereum Virtual Machine (EVM) protocol. However, Ledger Hardware wallets have introduced their own solution to digital signatures that distinguish between a traditional online approach.

Ledger Hardware Wallet Signatures: Comparison Web3.eth.personal.Sign

Ledger's equipment wallet, also known as Ledger Live, provides a safe and decentralized way to store, manage and sign Ethereum events. The signature mechanism of the Ledger Hardware wallet is based on theweb3.eth.personal.sign ()method, which uses the EVM signing protocol to authenticate users.

Main Differences Ledger Hardware Wallet signatures and web3.eth.personal.sign

between **

• Safety

  : Ledger's Hardware wallet uses a stronger cryptographic algorithm (RSassa-pss sha-384) compared to theweb3.eth.ersonal.sign ()method depending on Elliptic Curve Digital signature ).

• Compatibility : Ledger hardware wallet may be safe to interact with other Ethereum-compatible wallets and nodes, whileweb3.eth.personal.Sign ()is primarily designed for use in one online.

• Recording Requirements : Ledger equipment Wallets require storage space to store private keys, public addresses, and transaction histories, while theweb3.eth.personal.Sign ()method must only be stored by the user name or mnemonic seed.

• User Experience : LEDGER EQUIPMENT Wallet provides a more streamlined and user -friendly experience to sign events, features such as automatic password management and protected storage.

web3.eth.personal.Sign (Nonce, Coinbase): How does it work

Theweb3.eth.personal.Sign () method is a more traditional approach to digital signature creation in the Ethereum block chain. It takes two parameters: NONCE (random value produced by a user computer) andcoinbase (event situation or block number). The method uses the EVM signing protocol to sign an event that can be secured using web3.et.gettransaction (), web3.gettraSacttionreceipt () and web3.eth.sign () methods.

conclusion

While traditional network-based approaches, such as web3.eth.personal.Sign () offer easy-to-use and integration with existing Ethereum compatible wallets, Ledger's hardware offers wallet solutions a safer and decentralized way of using users. When building a DAPP in the Ethereum block chain, it is necessary to consider both options and choose the one that best meets your safety requirements and user experience needs.

Example Code: Signing the Event with Ledger Hardware Wallet

Here's an example of how to use the Ledger Live event to sign the event:

Javascript

Const Web3 = Require (‘Web3’);

Const ledger = Require (‘Ledgerlive’);

// Connect to Ledger Hardware wallet

Ledger.init ();

Const ledger = new main book ();

// Get your current nonce

Const nonce = wait for ledger.getnonceasync ();

// Create a new Ethereum account

Const tx = {

Sender: ‘0x …’,

to: ‘0x …’,

Value: 1,

Information: ‘…’. Repeat (20), // Event Information

};

// sign the event using the Ledger Hardware Wallet signature mechanism

Const Signature = Wait for Ledger.Signransaction (TX, NONCE);

// Confirm the signature using web3.et.gettransaction () method

Const txreceipt = Wait web3.eth.gettraSacttionreceipt (signature);

Console.log (signature signed: $ {signature}`);
