In this section, we show more exhaustive evaluation metrics computed for every subject individually using 40 hours and 1 hour of fine-tuning data, respectively.

AI agents are systems that can reason, act, and learn over time. They aren’t just passive tools. They’re active collaborators. We use them in software engineering to automate code reviews, triage bugs, and optimize performance. The same framework can be extended beyond code into healthcare, drug discovery, and clinical trials.

All platforms are now engaging, interactive. We can collaborate everywhere. To know the best platforms for evolving, we need to reflect on how we interact with these systems. Platforms, like authors, have style, have a culture. Pick the right culture that helps your path.

This section details a multi-layer blockchain system where a Layer-2 rollup manages CBDC integration and routing, while Layer-3s run competing AMMs. The architecture uses EVM, ensures compliance with KYC and privacy laws, and replaces bridges with proof-of-storage for enhanced security and cost-efficiency.

This study shows that a multi-AMM setup on Layer-2 blockchains reduces total costs of CBDC swaps—fees and price impact—compared to Project Mariana’s single-AMM model.

This section explains how Layer-2 rollups reduce costs and improve scalability for blockchain networks, and examines Project Mariana’s L1 AMM model for CBDC exchange.

This paper proposes a multi-layer blockchain system using Layer-2 and competing Layer-3 AMMs to enable cheaper, scalable cross-border CBDC trading, outperforming Project Mariana in simulations.
