What is the blockchain?

A beginner-friendly explanation of blockchain, why it matters, and how it enables crypto transfers and smart contracts.

A blockchain is a shared database where transactions are grouped into blocks and linked into a chain. Instead of a central operator (like a bank), the network uses cryptography and consensus rules to validate and record transactions. Key characteristics of blockchain technology:

• Decentralization: No single entity controls the network

• Transparency: All transactions are publicly visible

• Immutability: Once recorded, transactions cannot be altered

• Security: Protected by advanced cryptographic methods

• Consensus: Network participants validate transactions

Thanks to blockchain technology, transaction data remains unchangeable and always available for verification. This makes blockchain particularly suitable for:

• Financial transactions

• Digital asset management

• Smart contracts

• Supply chain tracking

• Identity verification

The TON blockchain, which MyTonWallet uses, is designed for high performance and scalability while maintaining security and decentralization.
