About XOX

XOX is a high-performance, decentralized perpetual futures exchange built as an app-specific execution layer secured by Ethereum.

XOX Stack: Deterministic Parallel & Modular Execution Engine

Challenge: Performance Bottlenecks in On-Chain Derivatives Trading

Despite rapid growth in DeFi, perpetual futures platforms continue to suffer from chronic issues: high latency, limited throughput, and architectural rigidity. Traditional blockchains process transactions sequentially on a single global state, creating severe bottlenecks that prevent sub-second execution required by professional and quantitative traders. Alternative designs that prioritize speed often sacrifice transparency, verifiable matching, or fair ordering. Monolithic DEX architectures further compound the problem — combining perpetuals with spot, lending, or other products increases gas costs, complexity, and upgrade friction.

Solution: XOX App-Specific Rollup

XOX Stack is purpose-built as an application-specific execution environment dedicated exclusively to ultra-low-latency derivatives trading. Instead of forcing trading workloads onto generic L1/L2 infrastructure, we re-engineer the execution layer from the ground up. By combining a modular multi-VM design with deterministic Parallel Transaction Execution (PTE), XOX delivers:

  • Multi-thousand TPS throughput

  • Sub-100ms matching latency

  • Fully verifiable, transparent order matching

  • Ethereum-finality security

Traders retain DeFi’s core trust-minimization guarantees while experiencing performance previously available only on centralized venues.

Three Core Technical Pillars

1. Modular Multi-VM Architecture**

Perpetual core logic runs in a dedicated xoxVM with isolated compute resources for minimum latency.

  • xoxVM → high-frequency matching, liquidation, funding rate, and risk engine

  • xoxEVM → standard DeFi operations (asset issuance, staking, governance)

  • Pre-compiled Contracts → heavy but stable computations (oracle updates, pricing models)

New trading products or features are added as independent VM actors with strict access-list isolation (EIP-2930 style), enabling seamless plug-and-play expansion without redeployments.

2. **Deterministic Parallel Transaction Execution (PTE)**

The sequencer receives transactions serially, but the execution engine parallelizes non-conflicting operations across multiple cores while preserving deterministic outcomes.

  • Market-sharded execution: each trading pair or product class runs in its own VM actor → zero cross-market contention

  • Intra-market parallelism via extended access lists → non-conflicting orders execute simultaneously

  • Fixed conflict resolution rules → identical replay on any node, guaranteeing verifiability and fraud-proof correctness

Throughput scales near-linearly with the number of active markets and available CPU cores.

3. PriorityLane QoS System

Transactions are automatically routed into two execution lanes:

  • Fast Lane → order placement, cancellation, reduce-only, liquidations (highest priority)

  • Standard Lane → deposits, withdrawals, governance, non-urgent operations

Professional traders can optionally use PriorityLane Boost — a commitment mechanism that returns near-instant soft confirmation (batch ID + projected inclusion slot) within milliseconds after submission, while remaining fully verifiable on-chain.

Security & Finality

All parallel execution streams converge into a single deterministic State Root via Parallel Merklization. This root is posted to Ethereum L1 (via an L2 rollup settlement layer), inheriting full Ethereum security. Any participant can independently replay the exact transaction batch to verify correctness — ensuring transparency and trustlessness identical to Ethereum mainnet, but with performance rivaling centralized exchanges.

XOX thereby eliminates the historical trade-off between speed and decentralization, delivering a true CeFi-grade trading experience in a fully non-custodial, verifiable environment.
