Basics of Cryptography
Cryptography is the practice of securing information by transforming it into an unreadable format, only accessible to those who possess a specific key. It’s fundamental to blockchain technology, ensuring the security and integrity of transactions.
Key Concepts:
- Encryption: Converts plain text into an unreadable format (ciphertext) using an algorithm and a key.
- Decryption: Converts ciphertext back to plain text using the correct key.
- Hashing: A process that converts data into a fixed-size string of characters, which is unique to the input data.
Public & Private Keys
Public and private keys are cryptographic tools essential for blockchain transactions.
Public Key: A public address visible to everyone, used to receive funds.
Private Key: A secret key known only to the owner, used to sign transactions and access funds.
The relationship between the two ensures that while anyone can send transactions to a public key, only the holder of the corresponding private key can access and manage those funds.
How Wallets Function
A wallet in the context of blockchain is a digital tool that stores your public and private keys, manages your cryptocurrency balances, and facilitates transactions.
Key Functions:
- Store Keys: Keeps your public and private keys safe.
- Manage Balances: Shows the amount of cryptocurrency you own.
- Facilitate Transactions: Allows you to send and receive cryptocurrency.
There are three types of wallets:
- Software Wallets
- Hardware Wallets
- Paper Wallets
Each type offers different features and levels of security. In this section, we’ll explore the specifics of each wallet type, including their descriptions, examples, security aspects, and usage scenarios. We’ll also cover the best practices for backing up each type of wallet to ensure your cryptocurrency remains safe and accessible. Whether you’re looking for convenience, high security, or long-term storage, understanding these wallet types will help you choose the best option for your needs.
- Software Wallets
Description: Digital wallets that run on software. They can be further divided into desktop, mobile, and online wallets.
Examples: MetaMask, Mycelium.
Security: Generally secure but vulnerable to malware and hacking if the device is compromised.
Usage: Convenient for frequent transactions and daily use.
Backup Methods:
a. Wallet File: Some wallets allow you to back up the wallet file, which contains your keys.
b. Seed Phrase: Most modern wallets provide a 12–24 word seed phrase during setup. This phrase can be used to recover your wallet.
Steps to Backup:
1. Locating the Backup Option: In the wallet application, the user should look for a “Backup” or “Settings” menu.
2. Exporting The Wallet File: If the wallet uses a wallet file, the user should follow the instructions to export and save it securely.
3. Writing Down The Seed Phrase: If they’re using a seed phrase, the user should write it down on paper, ensuring it is written correctly and in the correct order.
2. Hardware Wallets
Description: Physical devices that store private keys offline.
Examples: Ledger Nano S, Trezor.
Security: Highly secure as they are immune to online hacking.
Usage: Ideal for storing large amounts of cryptocurrency for long periods.
Backup Methods:
a. Seed Phrase: During the initial setup of a hardware wallet, it will generate a seed phrase. The user should write it down on the provided recovery sheet or a piece of paper.
b. Secure Storage: The user should create multiple copies of the seed phrase. The user should store these copies in secure places, such as a fireproof safe or safety deposit box.
3. Paper Wallets
Description: Physical pieces of paper with your private and public keys printed on them.
Security: Secure from online threats but can be damaged, lost, or stolen.
Usage: Good for long-term storage but not practical for frequent transactions.
Backup Methods:
a. Creating Multiple Copies: When generating a paper wallet, the user should print multiple copies.
b. Laminating: The user should consider laminating the paper to protect it from water damage and wear.
c. Secure Storage: The user should store the copies in secure places, such as a fireproof safe or safety deposit box, and they should never share their paper wallet with anyone they don’t fully trust.
Cryptography’s Role in Wallets
Cryptography ensures that:
- Transactions are secure: Only the private key holder can authorize transactions.
- Funds are protected: Even if a public key is known, funds cannot be accessed without the private key.
- Integrity is maintained: Transactions cannot be altered once they are added to the blockchain.
Current State: User-Friendly and Secure
Today, blockchain applications leverage these advancements to provide a much more user-friendly and secure experience. Users no longer need to manually enter their private keys for each transaction. Instead, they benefit from:
- Automatic Signing: Wallets handle the signing process in the background using securely stored private keys.
- Convenient Authentication: Users authenticate transactions using passwords, PINs, or biometric methods.
- Enhanced Security: Hardware wallets, multi-signature solutions, and secure elements protect private keys from unauthorized access and online threats.
These improvements have made blockchain technology more accessible and practical for everyday use, significantly enhancing the overall user experience.
Use Case: Blockchain-Based Payment App
A blockchain-based payment app allows users to send and receive cryptocurrency payments securely and efficiently without repeatedly entering their private key.
How Public and Private Keys Are Used with Enhanced UX:
- User Registration:
- When a user registers for the payment app, the system generates a public and private key pair for them.
- The private key is securely stored on the user’s device, often encrypted and protected by a password or biometric authentication (such as a fingerprint or facial recognition). - Sending Payments:
- The user initiates a transaction to send cryptocurrency to another user.
- The app automatically uses the recipient’s public key to encrypt the transaction details. - Transaction Signing:
- Instead of entering the private key manually, the user authenticates the transaction using a more convenient method, such as:
a. Password/PIN: The user enters a pre-set password or PIN to confirm the transaction.
b. Biometric Authentication: The user uses fingerprint or facial recognition to authorize the transaction.
The app then uses the stored private key to sign the transaction securely in the background. - Broadcasting the Transaction:
- The signed transaction is broadcast to the blockchain network.
- Network nodes verify the digital signature using the sender’s public key, ensuring the transaction’s authenticity. - Receiving Payments:
- The recipient receives the encrypted transaction details.
- They use their private key, stored securely on their device, to decrypt the information. - Verification and Completion:
- The transaction is added to the blockchain, providing a transparent and immutable record.
- Both the sender and recipient can view the transaction details, ensuring transparency and trust.
User Experience Enhancements
Security:
- The app uses encryption to store the private key securely on the user’s device, reducing the risk of unauthorized access.
- Multi-factor authentication (MFA) can be implemented for an additional
layer of security.
Usability:
- Users authenticate transactions with simple, familiar methods (password, PIN, or biometrics) instead of entering the private key each time.
- The app provides clear, step-by-step guidance during the transaction process to ensure users understand what is happening.
Trust and Transparency:
- The app displays confirmation screens showing the transaction details before the user finalizes the transaction.
- Users receive notifications when transactions are successfully signed, broadcast, and verified, providing reassurance that the process is secure and complete.
- By implementing these user-friendly methods, the payment app ensures that users can perform secure transactions conveniently without repeatedly entering their private keys, enhancing both security and user experience.
