Axis Chain's Approach
Axis Chain adopts a modular blockchain architecture, decoupling key functions—consensus, execution, and data availability—into specialized layers. This design ensures that the network remains scalable, secure, and flexible while maintaining efficiency and decentralization. By separating these layers, Axis Chain can avoid bottlenecks and optimize each layer for its specific task.
In this architecture, PoL (Proof of Liquidity) and PoT (Proof of Transfer) form the backbone of the consensus layer, ensuring that the network is both secure and highly performant. Axis Chainleverages these dual mechanisms to maintain a lean and efficient network.
Consensus Layer: Secured by PoL and PoT
The consensus layer in Axis Chain is secured by two mechanisms working in tandem: PoL (similar to Ethereum 2.0’s PoS model) and PoT, which adds an additional layer of security based on validators' performance and participation.
Proof of Liquidity (PoL)
PoL in Axis Chain operates similarly to Proof of Stake (PoS) in Ethereum 2.0, but instead of using ETH, it leverages Axis Chain liquidity. Validators must stake liquidity instead of tokens, with the following key features:
Liquidity Delegation: Validators are selected based on the amount of liquidity they stake. Liquidity providers can delegate their assets to validators, allowing them to participate in network security while maintaining access to their liquidity for other purposes.
Incentives for Validators: Validators earn rewards based on their contribution to securing the network. The more liquidity a validator has staked (from their own holdings and from delegators), the higher their chances of being selected to validate blocks. This incentivizes validators to accumulate liquidity and act honestly to earn rewards.
Penalties and Slashing: Validators who behave maliciously or fail to validate blocks properly can be penalized through slashing, where they lose a portion of their staked liquidity. This creates a strong disincentive against dishonest behavior, ensuring that validators act in the best interests of the network.
This PoL mechanism ensures a high degree of decentralization, as liquidity providers can choose which validators to delegate their liquidity to, promoting a balanced distribution of security across the network.
Proof of Transfer (PoT) for Additional Security
PoT is introduced as a secondary layer of security in Axis Chain’s consensus mechanism. It enhances the reliability of the network by evaluating validator performance based on the correctness and volume of the transactions they validate. PoT serves to weight validator influence based on actual network contributions over time.
Transaction-Based Validation: PoT assigns a weight to each validator based on their history of validating correct transactions. Validators who consistently validate correct blocks and handle a large volume of transactions gain additional trust and influence in the network.
Performance Incentives: Validators who process more correct transactions are given a greater role in validating future blocks. This performance-based approach ensures that the most reliable and active validators are given more responsibility, which further secures the network.
Double-Layered Security: By combining PoL and PoT, Axis Chain creates a double-layered security model. PoL ensures that validators have a financial stake in the network, while PoT rewards active participation and correctness in validation. This dual mechanism ensures that the network is both secure and efficient, as validators are incentivized not only by their staked liquidity but also by their performance in processing transactions.
PoT adds a performance-based weight to the validation process, ensuring that the network is protected not just by financial stakes but also by validators’ contributions to the network’s overall security and throughput.
Execution Layer
In Axis Chain’s modular design, the execution layer is decoupled from consensus and data availability. This layer handles the execution of smart contracts and transactions, allowing for parallel processing of transactions without overloading the consensus layer.
Off-Chain Execution: Much of the transaction execution is handled off-chain to reduce the load on the consensus layer. Axis Chain can leverage rollup technologies, where transactions are executed off-chain and then submitted to the main chain for validation and finality.
Optimized Throughput: The modular structure allows the execution layer to focus purely on transaction processing, enabling the network to handle a large number of transactions efficiently without compromising security.
Data Availability Layer
The data availability layer ensures that the transaction data required to verify blocks is readily accessible to participants. This layer guarantees that even though execution happens off-chain, the data required to validate these transactions is available on-chain.
Data Sampling and Redundancy: Axis Chain uses techniques such as data availability sampling to verify that the necessary transaction data is available without requiring all nodes to store the entire history of transactions. This reduces the storage burden on validators while ensuring data availability.
Interoperability: The data availability layer also facilitates interoperability between different blockchains, enabling Axis Chain to interact with other ecosystems and allow assets to move freely between chains.
Decentralized Oracle Network (DON)
The Decentralized Oracle Network (DON) is a critical component of the Axis Chain's technical architecture, focusing on enabling secure data transmission between off-chain sources and Axis Chain through cross-chain liquidity.
Data Fetching and Verification: DON is responsible for fetching and verifying essential off-chain data from provided data sources, ensuring its accuracy and integrity before securely integrating it into Axis Chain.
Decentralized Transmission: By leveraging a network of decentralized nodes, DON guarantees secure and tamper-resistant data transmission, reducing the risk of single points of failure and enhancing the robustness of the system.
Cross-Chain Interactions: DON supports seamless interactions with multiple blockchain ecosystems, enhancing the interoperability of Axis Chain and allowing effective utilization of various assets.
Efficient Computation: DON executes necessary computations for off-chain data processing, ensuring operations are efficient without compromising system security.
Real-Time Updates: DON provides real-time data updates, improving the responsiveness and functionality of Axis Chain and its decentralized applications, ensuring they can quickly adapt to changes in off-chain data
Decentralization and Flexibility
Axis Chain’s modular approach ensures that each layer can evolve independently, allowing for continuous improvements and upgrades without disrupting the entire network. The modular architecture promotes decentralization by:
Decoupling Consensus and Execution: Validators can focus on securing the network without being overburdened by transaction execution, while specialized nodes handle the execution off-chain.
Incentivized Participation: Both liquidity providers and validators are incentivized to participate in the network, ensuring broad decentralization and reducing the risk of centralization.
Scalability and Efficiency
The separation of functions across different layers allows Axis Chain to scale efficiently. As network demand grows, each layer can scale independently:
Consensus Layer Scaling: Validators are selected based on PoL and PoT, ensuring that only those who are financially and performance-wise committed to the network participate in consensus.
Execution Layer Scaling: Off-chain execution allows Axis Chain to handle large volumes of transactions without overloading the main chain. Rollup solutions provide scalability while maintaining security.
Data Availability: By decoupling data storage and availability from execution and consensus, Axis Chain can reduce the burden on validators and ensure that the network can grow without
