How Crypto Wallet Digital Signatures Work

With defensively built crypto wallets such as the Ledger Nano wallets, crypto transactions are authorized and completed using digital signatures.

If you are curious to know how these digital signatures work, then you are on the right page.

Key Takeaways

• With digital signatures, users can safely process and complete crypto transactions through their crypto wallets.

• A Digital signature is proof that a crypto transaction was authorized by a sender to a receiver and shows that such transactions are genuine and valid.

• Private keys guarantee access to your crypto assets and as such, they should be kept safely to avoid misplacement.

• Contrary to popular opinion, crypto wallets do not store your crypto assets as they are held on the blockchain rather they preserve your crypto assets through your public and private keys.

Crypto Wallet Digital Signatures

Crypto wallet digital signatures are simply a method of validating a particular crypto transaction to ascertain that it is valid and genuine.

These digital signatures contain public key information which can be used to identify the sender.

Also, the signer and the sender’s information must be similar if the digital signature is to be accepted and the transaction is to be confirmed.

With digital signatures, two important concepts play pivotal roles in its existence. These concepts are Hashing, and Asymmetric cryptography.


How Crypto Wallet Digital Signatures Work

Hashing simply means the process of converting data into a unique set of code. There are various types of hashing functions one, in particular, being the secure hash algorithm (SHA) used for bitcoin.

The hashing function serves to determine the validity of any transaction data and it does this by converting a message into a set of code for instance, “A591A6D40BF420404A011733CFB7B190D62C65BF0BCDA32B57B277D9AD9F146E”.

As you can see, the code is 64 digits long with each digit representing 4 bits (adding up to 256 bits ultimately).

If this code was to be altered in any way such as changing a capital D to a small d for instance, the code would mean a different thing altogether.

This, therefore, shows how delicate these codes are considering that they are an important part of data integrity since it would be easy to tell when a code has been modified or tampered with.

Asymmetric Cryptography

Asymmetric Key - How Crypto Wallet Digital Signatures Work

Cryptography is the process of securing transaction information by using codes in such a way that only the receiver of a transaction can read or process the transaction information.

Asymmetric cryptography on the other hand is one of the types of cryptography that grants users access to a pair of keys known as public keys and private keys.

A public key can be shared freely with anyone, while the private key is strictly confidential, only for the user; it cannot be shared or disclosed.

A simple analogy is that a public key resembles your bank account, while a private key resembles your pin to access your bank account.

For instance, let us look at a scenario in which Henry wants to send crypto to Donald.

In doing that, he will need to encrypt the transaction by using Donald’s public key as the only way to decrypt the transaction is by using Donald’s matching private keys.

Donald is the only one who knows his private keys and would use them to decrypt the transaction.

Asymmetric cryptography, in this case, provides confidentiality and security, allowing the secure sharing of public keys over untrusted mediums such as the Internet.

Just like you would store money in a traditional wallet, you can as well store crypto in a crypto wallet.

The only difference here is that crypto wallets preserve ownership of your crypto rather than just keeping it as a traditional wallet would.

For you to gain access to your crypto, you would need to be in ownership of a private key as that is what proves that you are the verified owner of the crypto wallet and the crypto assets as well.

A crypto wallet exists to provide opportunities for users to be able to create and manage their private keys.

The wallet helps in creating the necessary transaction details and digital signature to ensure ownership of the private key.

As made mentioned above, transaction information stored in the blockchain is written according to a set code and sent to the network with a digital signature. When the transaction is validated, it gets recorded on the blockchain ledger.

Since cryptocurrencies have different networks for each type, the wallet assists you in selecting it and writing the transaction details for the network.

This is why different types of crypto wallets support different cryptocurrencies since some of these cryptocurrencies may not be compatible due to their differing networks.

Frequently Asked Questions (FAQs)

What is a cryptocurrency wallet address?

A Cryptocurrency wallet address is a set of characters that exist to facilitate crypto transactions and can be accessed through a crypto wallet.

There are usually different types of crypto wallet addresses depending on the wallet in question.

How secure should private keys be stored?

Private keys should be highly secured as that is one of the most important things you should be very protective of.

Currently, the technology to recover private keys in case it is misplaced or forgotten does not exist so you might want to keep them as safe as possible.

Does Bitcoin use a digital signature?

Yes, bitcoin and all other cryptocurrencies require digital signatures to enable successful crypto transactions from one user to another.

These digital signatures are used to prove ownership of specific coins and to authorize their transfer to a new owner.

Final Thoughts

Crypto wallet digital signatures are an important part of the dynamism surrounding crypto transactions.

With it, proof of crypto ownership can be validated, and crypto transactions can be successfully processed.
