QAN

A blockchain is a decentralized, public ledger that is continuously updated and shared across a vast network of computers. Each participant in the network maintains a copy of the database, ensuring transparency and security.

The term "block" refers to the grouping of transaction data and state information into sequential units called "blocks." For instance, when you send QAN tokens to another user, the transaction details must be included in a block to be validated and recorded. This process ensures the integrity and immutability of the data.

The term "chain" highlights the cryptographic linkage between blocks, where each block contains a reference to its predecessor. This creates an unbreakable chain of blocks, meaning that altering the data in one block would require changing all subsequent blocks. Such a change would demand the consensus of the entire network, making tampering virtually impossible.

Every computer or "node" in the network must agree on the validity of each new block and the overall state of the chain. Nodes play a critical role in maintaining consistency, ensuring that all participants interact with the same data. To achieve this distributed agreement, blockchains rely on a consensus mechanism.

QAN, as the world's first quantum-proof blockchain, employs a cutting-edge consensus mechanism designed to withstand the computational power of quantum computers. Unlike traditional systems, QAN integrates quantum-resistant algorithms to secure its network. Validators in the QAN ecosystem stake QAN tokens as collateral and run specialized software to propose and verify blocks. These validators are randomly selected to propose new blocks, which are then checked and added to the blockchain by other validators. A robust system of rewards and penalties ensures that participants remain honest and highly available, further enhancing the network's security and reliability.

By combining quantum-proof technology with a decentralized consensus mechanism, QAN is paving the way for a new era of blockchain innovation, ensuring long-term security in the face of emerging quantum threats. 🌌🔗
