How XNO Works: A Closer Look at Nano's Cryptocurrency Design
XNO, the cryptocurrency native to the Nano blockchain, aims to provide a highly efficient and lightweight digital payment system. Unlike many traditional blockchain technologies that rely on energy-intensive mining and complex consensus mechanisms, XNO offers a unique framework for peer-to-peer transactions. Here's a breakdown of how XNO works and the technology that supports it.
Block Lattice Structure
Central to Nano's functionality is its block lattice architecture, which differentiates it from conventional blockchain frameworks. Instead of a single, universal blockchain, each account in the XNO network maintains its own blockchain, referred to as an "account-chain." This design allows for asynchronous updates, meaning users can submit transactions independently of the rest of the network. As a result, XNO achieves fast transaction speeds while minimizing bottlenecks.
Delegated Proof of Stake (DPoS)
XNO uses a variation of the Proof of Stake (PoS) consensus mechanism called Delegated Proof of Stake (DPoS). In this system, users can delegate their voting weight to a representative node, which participates in the verification of transactions. These representatives resolve conflicts in the network by voting on the validity of blocks. Since DPoS does not require energy-intensive mining as seen in Proof of Work (PoW) systems, the protocol ensures high energy efficiency.
Send-Receive Transaction Model
Another distinctive feature of XNO's design is its two-step transaction process. To complete a transaction, both the sender and receiver must interact with the network: the sender must create a "send block," while the receiver must generate a "receive block." This approach contributes to balance security and eliminates the risk of double-spending without requiring a centralized intermediary. The balance updates in the account-chains reflect these changes in real-time.
Transaction Fees
XNO transactions are fee-free by design. This is facilitated by the lightweight protocol and absence of miners in the network. Instead of paying transactional fees, XNO users rely on the system's efficient mechanisms to process and validate transactions. The lack of monetary fees makes XNO appealing for micropayments and frequent transfers of small sums.
Lightweight Nodes
The core infrastructure of XNO supports lightweight nodes, making it possible to run a node on less powerful hardware compared to many other blockchain ecosystems. This enhances accessibility while reducing barriers to entry for users who wish to participate in securing the network or monitoring the blockchain.
Finality Through Open Representatives
XNO achieves transaction finality through its network of open representatives, who confirm blocks based on consensus. These representatives are typically trusted nodes within the ecosystem, and their activity ensures the system remains functional and resistant to malicious activity, such as attempts at 51% attacks.
