Othentic is a development framework designed for building robust distributed systems that integrate with Shared security protocols. The network's governance is implemented by AvsGovernance, which is the endpoint for network members' management and deposits. The network has the ability to control stake tokens, depending on the performance of tasks, and vote against bad acting.

To reduce costs and improve efficiency, we deploy AvsGovernance on Layer 1 and AttestationCenter on Layer 2. Since they run on separate networks and can't interact directly on-chain, we use LayerZero to handle message passing between them.

Packages

The core contracts fall into the following categories in the GitHub repository:

Package	Description
src/NetworkManagement/L1	Layer 1 contract implementations
src/NetworkManagement/L2	Layer 2 contract implementations
src/NetworkManagement/lz	LayerZero-based messaging interfaces between L1 and L2

Contracts

Layer 1 Components — Governance Layer

1. AvsGovernance: The core governance contract for the AVS that manages Operator registrations, Stake deposits and withdrawals and Protocol-level decision making

Layer2 Components — Task & Attestation Layer

1. AttestationCenter is a contract on Layer 2 that is manage tasks of the AVS validators. It informed by the validators about historical tasks executions and votes
2. OBLS is the contract that implements multisig operations
3. BN256G2 is a cryptographic logical contract that used by OBLS.

Inter-Layer Communications

Othentic uses LayerZero protocol to facilitate secure cross-layer messaging:

1. l1MessageHandler Connected to AvsGovernance, it is an endpoint for communication with Layer 2 components. When activate it act like a router and also a broadcast for Layer 2.
2. l2MessageHandler Connected to AttestationCenter, this contract is the complement contract to l1MessageHandler, an endpoint for communication with Layer 1.

Message Flow

Communication between layers follows this pattern:

// From Layer 2 → Layer 1
L2MessageHandler.sendMessage(payload)
   ⟶ L1MessageHandler.receive(payload)

// From Layer 1 → Layer 2
L1MessageHandler.sendMessage(payload)
   ⟶ L2MessageHandler.receive(payload)
