Chain Abstraction & State Sync

In this section, we delve into how ODX achieves chain abstraction by communicating with multiple blockchains and maintaining their states within its own network. This mechanism allows users to interact seamlessly with various blockchains through a single ODX account, eliminating the need to switch between different wallets or networks. The process is akin to how Thorchain facilitates cross-chain swaps, but within the unique context of ODX 's architecture.

Overview

Chain abstraction in ODX is achieved through a combination of cross-chain communication protocols, state synchronization mechanisms, and transaction orchestration. ODX acts as an intermediary that interfaces with supported blockchains, enabling asset swaps and state updates without exposing users to the complexities of each individual chain.

Core Components

Cross-Chain Communication Modules - These modules handle the interaction between ODX and external blockchains.

State Synchronization Engine - Maintains the state of external blockchains within ODX .

Transaction Orchestrator - Manages the sequence of operations required for cross-chain actions.

Liquidity Pools and Asset Management - ODX maintains liquidity pools for bridging assets like USDT and USDC to Facilitate instant settlements and swaps across chains.

Process Flow

State Tracking and Synchronization

ODX continuously tracks the state of supported blockchains to reflect accurate balances and enable cross-chain operations.

Block Monitoring:

ODX monitors new blocks on external chains using light clients or full nodes. Extracts relevant transaction data and state changes.

State Update Function:

For each supported blockchain $B_i$, the state $S_t$ at time $t$ is updated as:

$$S_{B_i}(t) = S_{B_i}(t - \Delta t) + \Delta S_{B_i}(t)$$

Where $\Delta S_{B_i}(t)$ represents the state changes detected between $t - \Delta t$ and $t$.

Consistency Verification:

Merkle proofs and cryptographic validations ensure the correctness of the state updates. ODX verifies that the state changes are valid and have reached finality on the external chain.

Cross-Chain Communication

ODX uses standardized protocols to communicate with external blockchains.

Protocol Bridges:

Implementations of Inter-Blockchain Communication (IBC) where applicable. Custom bridges for non-IBC-compatible chains.

Message Passing:

Transactions and commands are encapsulated in messages $M$ sent to external chains. Each message contains necessary data and signatures for execution.
