Solana Oasis: Whitepaper

Version 1.0.0

Abstract

Solana Oasis introduces a novel Layer 2 scaling solution for Solana that specializes in AI computation offloading while maintaining security and decentralization. By combining optimistic rollups with a distributed AI computation layer, we enable scalable, verifiable AI operations that can be anchored to Solana's high-performance L1.

1. Introduction

1.1 Background

The increasing demand for AI-powered blockchain applications has created a need for scalable, decentralized computation solutions. While Solana provides high throughput for traditional transactions, AI computations require specialized infrastructure and significant resources.

1.2 Problem Statement

• Heavy AI computations are incompatible with direct on-chain execution
• Need for verifiable AI results in a trustless manner
• Requirement for low-latency AI operations with blockchain integration
• Data availability challenges for large AI models and datasets

2. Technical Architecture

2.1 Layer 2 Design

Solana Oasis implements a hybrid architecture:

2.1.1 Optimistic Rollup Core

• Batch transactions and state updates
• 7-day challenge period for fraud proofs
• State roots posted to Solana L1
• Efficient compression of transaction data

2.1.2 AI Computation Layer

• Distributed network of AI computation nodes
• Model registry and versioning system
• Selective ZK-proof generation for critical computations
• IPFS/Arweave integration for model and data storage

2.2 Consensus Mechanism

2.2.1 Hybrid Consensus

pub struct ConsensusConfig {
    // Minimum stake required for AI computation nodes
    min_stake: u64,
    // Required computation power (TFLOPS)
    min_compute_power: u32,
    // Maximum time for computation verification
    max_verification_time: u32,
    // Challenge period in slots
    challenge_period_slots: u64,
}

2.2.2 Proof of Computation

• Hardware attestation for AI nodes
• Performance benchmarking
• Resource monitoring and reporting

2.3 Bridge Protocol

2.3.1 Asset Bridge

pub trait BridgeProtocol {
    fn deposit(
        &mut self,
        amount: u64,
        token: TokenAccount,
        destination: L2Address,
    ) -> Result<TxSignature>;
    
    fn withdraw(
        &mut self,
        amount: u64,
        proof: WithdrawalProof,
        destination: SolanaAddress,
    ) -> Result<TxSignature>;
}

2.3.2 State Synchronization

• Merkle tree state commitments
• Fraud proof verification
• Emergency exit mechanism

3. AI Integration

3.1 Supported AI Operations

3.1.1 Large Language Models

class LLMInterface:
    def inference(
        self,
        model_id: str,
        input_text: str,
        params: Dict[str, Any]
    ) -> Tuple[str, Proof]:
        """
        Execute LLM inference with proof generation
        """
        pass

3.1.2 Data Analysis

• Real-time market data processing
• On-chain data analytics
• Pattern recognition and prediction

3.2 Verification System

3.2.1 ZK-Proof Generation

pub struct AIComputationProof {
    // Input hash
    input_hash: Hash,
    // Output hash
    output_hash: Hash,
    // ZK proof for computation correctness
    zk_proof: Vec<u8>,
    // Computation metadata
    metadata: ComputationMetadata,
}

4. Smart Contract Architecture

4.1 Core Contracts

4.1.1 State Manager

#[program]
pub mod state_manager {
    use super::*;
    
    pub fn update_state(
        ctx: Context<UpdateState>,
        new_state_root: [u8; 32],
        proof: StateUpdateProof,
    ) -> Result<()> {
        // Verify and update state
    }
}
