12-Hour Fraud Proof Window

Enhancing Security and assuming optimistic Finality

Symmio is designed with a structure akin to an optimistic layer 2 solution, enabling a robust, efficient, and decentralized trading system. At its core, Symmio operates on the principle of optimistic finality, assuming that all transactions are valid and finalized instantly, regardless of the underlying blockchain's finality. This approach not only enhances the speed and usability of the platform but also integrates a 12-hour fraud proof window to provide critical security and reliability benefits.

Benefits of the 12-Hour Fraud Proof Window

  1. Instant Finality with Layered Protection By assuming transactions are instantly final, Symmio eliminates delays typically associated with blockchain finality, such as the 15-minute wait for confirmation on certain chains. This ensures seamless and real-time trading experiences for users while maintaining a safety mechanism to review potentially malicious activities during the fraud proof window.

  2. Zero-Day Exploit Mitigation The 12-hour fraud proof window acts as a protective layer against unforeseen vulnerabilities or zero-day exploits. This buffer period allows the system to detect, verify, and address any anomalies before they can propagate further.


Symmio’s Layered Verification Model

Symmio employs a multi-layered verification system to ensure trust and fairness, even within its optimistic framework. The roles and interactions between key participants are structured as follows:

Layer 1: User ↔ Solver Relationship

  • Users and Solvers interact directly to execute trades and transactions.

  • In the event of a dispute, the Oracle serves as an impartial arbiter to resolve disagreements based on predefined rules.

Layer 2: Oracle Fraud Protection

  • Should a malicious actor compromise or manipulate the Oracle, the Fraud Proof Checkers serve as an additional safeguard.

  • These checkers are empowered to suspend users and address discrepancies, acting as a failsafe mechanism.

Fraud Proof Checkers: Final Security Layer

  • Fraud proof checkers monitor for issues such as double spends—a scenario usually prevented by blockchain finality.

  • In Symmio, solvers can’t afford to wait for on-chain finality (e.g., 15 minutes). Instead, they act optimistically, trusting the system’s layered security to catch and address any violations during the 12-hour fraud proof window.


Why This Approach Works for Symmio

Symmio’s unique blend of optimistic finality and layered verification ensures that:

  • Transactions are processed in real time for optimal user experience.

  • System integrity is maintained through a combination of oracles and fraud proof checkers.

  • The 12-hour fraud proof window provides a secure fallback to address any irregularities, reinforcing trust in the ecosystem.

By combining instant usability with robust security, Symmio strikes the perfect balance between speed and reliability, paving the way for a decentralized and censorship-resistant derivatives market.
