Layer 2 Scaling Solutions
Layer 2 technologies are revolutionizing DeFi by enabling high-throughput, low-cost transactions while maintaining security.
Rollup Technology
⚡ Scaling Innovations:

- ZK-Rollups: Zero-knowledge validity proofs
- Validium: Off-chain data availability
- Volition: User choice between security levels
Optimistic Rollups Implementation
// Optimistic rollup state management
class OptimisticRollup {
constructor() {
this.stateRoot = '0x000...'; // Initial state
this.pendingBlocks = [];
this.challengePeriod = 7 * 24 * 60 * 60; // 7 days
this.challenges = new Map();
}
submitBatch(transactions) {
const batch = {
transactions,
prevStateRoot: this.stateRoot,
timestamp: Date.now(),
batchHash: this.hashTransactions(transactions)
};
// Post state root to main chain
this.postStateRoot(batch);
// Start challenge period
this.startChallengePeriod(batch);
this.pendingBlocks.push(batch);
}
startChallengePeriod(batch) {
setTimeout(() => {
if (!this.challenges.has(batch.batchHash)) {
// No challenges, batch is valid
this.finalizeBatch(batch);
}
}, this.challengePeriod);
}
challengeBatch(batchHash, fraudProof) {
if (this.verifyFraudProof(fraudProof)) {
// Fraud proven, revert batch
this.revertBatch(batchHash);
// Reward challenger
this.rewardChallenger(fraudProof.challenger);
}
}
verifyFraudProof(proof) {
// Verify the fraud proof against on-chain state
return this.verifyTransition(proof.preState, proof.postState, proof.tx);
}
}

// Lock asset on source chain
await this.lockAsset(fromChain, asset, amount);
// Create transfer request
const transferRequest = {
id: transferId,
fromChain,
toChain,

}
}
