The Latin word porta means "gate" or "entrance" and as the name suggest, the ZexPorta is responsible for two critical tasks:
Monitoring Blockchain Deposits Tracking blockchain activity to extract token deposits directed to ZexCora.
Processing Withdrawal Requests Retrieving and processing withdrawal requests from the ZexCora in a secure and efficient manner.
To ensure a decentralized implementation, the ZexPorta module leverages the , a Python implementation of the (Flexible Round-Optimized Schnorr Threshold) protocol, to issue threshold signatures. For further information on PyFrost, please refer to the .
The ZexPorta module comprises three key components:
Deposit Component
Monitors blockchain activity to identify ERC20 token transfer transactions.
Filters transactions where the recipient matches a user’s deposit address within the platform.
Acts as a data layer to store deposit transaction details.
Serves as the Signature Aggregator (SA) for PyFrost, sending deposit data to be verified.
Withdraw Component
Retrieves withdrawal requests from the Zex core and stores them in a database for processing.
Functions as the Signature Aggregator (SA) for PyFrost, coordinating signature handling.
Sends withdrawal requests to validators for data verification and issuing a signature share for execution.
Validator
Validators act as nodes within the PyFrost network.
Responsible for validating both deposit and withdrawal transactions.
Issues partial signatures, which are aggregated and verified by the Zex core and Vault contract before final approval.
Decentralization: Validators distribute the responsibility of transaction validation across multiple independent nodes, minimizing the risk of centralization.
Security: The use of threshold signatures ensures that no single Validator can compromise the system. A quorum of Validators must collaborate to approve a transaction.
Scalability: The Validator architecture can scale with the growth of the Zex ecosystem, ensuring efficient validation even as transaction volume increases.
In the upcoming sections, we provide a detailed breakdown of each component, highlighting their roles and how they contribute to the secure and decentralized operation of Zex.
