Decentralized Transaction Network (DTN)
The Decentralized Transaction Network (DTN) is responsible for orchestrating multi-chain transactions and asynchronous workflows in the Okto ecosystem. It reads user jobs from the Okto Chain and decomposes them into sub-transactions, coordinating their execution across multiple blockchain networks. DTN ensures that transactions are executed in a secure, efficient, and verifiable manner by interfacing with both the DWN and ULL, while recording critical checkpoints on the Okto Chain.
Core Functionality
The DTN's primary function is to interpret and execute user intents that may or may not span multiple blockchains. It breaks down complex requests into manageable sub-transactions, coordinates with other Okto components (DWN, ULL), and ensures the successful and verifiable execution of cross-chain operations.
Key functionalities include:
-
Intent-Driven Execution: Breaks down a complex user intent (e.g., a multi-chain token swap) into sub-transactions that can be executed independently on target chains.
-
Asynchronous Transaction Management: Manages sub-transactions asynchronously, optimizing for speed and efficiency across chains with varying confirmation times.
-
Unified Liquidity Layer (ULL) Interaction: Leverages the ULL to identify and utilize optimal optimal liquidity route for each sub-transaction, ensuring cost-effectiveness and efficiency.
-
Decentralized Wallet Network (DWN) Coordination: Collaborates with the DWN to securely obtain transaction signatures.
-
On-Chain Verification and Transparency: Commits transaction payloads and execution status to the Okto Chain, providing an immutable and auditable record of all DTN operations.
-
Error Handling and Retries: Implements error handling and automated retry mechanisms to ensure transaction completion and resilience to network issues.
Architecture and Technology
-
Decentralized Node Network: Operates as a network of specialized nodes responsible for bidding on and executing jobs. Nodes are selected via a competitive bidding process based on performance, cost efficiency, and reputation.
-
Asynchronous Transaction Management: Employs an asynchronous model to manage sub-transactions across different chains, accommodating varying confirmation times and network latencies.
