What is the encryption principle of cryptocurrency?
The encryption principle of cryptocurrency consists of several core concepts, including: Cryptozoology basics: hash function, asymmetric encryption. Blockchain technology: block, chain structure. Digital signature: Private and public keys are used to verify transactions. Proof of Work: Miners solve mathematical puzzles to verify transactions. Consensus mechanism: Nodes verify and broadcast transactions, determine valid transactions through consensus, and ensure the security, decentralization and non-tamperability of cryptocurrency.
The encryption principle behind cryptocurrency
The encryption principle behind cryptocurrency consists of the following core concepts:
1. Basics of cryptography:
- Hash function: Generate a unique and irreversible digital fingerprint, used to create transaction records.
- Asymmetric encryption: Use public and private keys to encrypt and decrypt data.
2. Blockchain technology:
- Block: Contains transaction records, timestamps and cryptography Greek digital records.
- Chain structure: Each new block references the previous block, forming an unchangeable timestamp sequence.
3. Digital signature:
- The private key is used to create a digital signature of the transaction to verify the authenticity of the transaction.
- The public key is used to verify the digital signature, ensuring that only the person with the private key can send the transaction.
4. Proof of Work:
- Miners use computing power to solve complex mathematical puzzles to verify transactions.
- After solving the puzzle, the miner is rewarded with cryptocurrency.
5. Consensus mechanism:
- Nodes verify and broadcast transactions in the network.
- Through consensus mechanisms, such as proof of work or proof of equity, nodes reach consensus and determine valid transactions on the network.
These basic principles ensure the security, decentralization and immutability of cryptocurrencies. Hash functions and digital signatures prevent transactions from being forged or altered. Blockchain technology provides a transparent and immutable record of transactions. Proof-of-work and consensus mechanisms ensure the security of the network and prevent double spending.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
