# The problem

### Overview of DeFi Lending

Decentralized Finance (DeFi) has transformed traditional financial paradigms by eliminating intermediaries and fostering a permissionless, transparent, and trustless environment. DeFi lending protocols allow users to earn interest on supplied assets or borrow assets by providing collateral. Despite their growth, existing protocols face significant challenges:

* Capital Inefficiency: High collateralization ratios lock up capital, reducing liquidity and capital utilization. Users often have to over-collateralize their loans, sometimes by 150% or more, which is inefficient for both borrowers and the ecosystem.
* Limited Cross-Chain Functionality: Most lending protocols operate within a single blockchain ecosystem, restricting asset utilization and liquidity to that network. This fragmentation prevents users from leveraging opportunities across different chains.
* Scalability Issues: Network congestion on platforms like Ethereum leads to high gas fees and slow transaction processing times, hindering user experience and accessibility, especially for smaller investors.
* Security Concerns: Smart contract vulnerabilities, centralized price oracles, and susceptibility to flash loan attacks pose significant risks to user funds and protocol stability.
* Governance Centralization: Voting power in many protocols often concentrates among large token holders, undermining the decentralized ethos and potentially leading to decisions that favor a minority over the broader community.

### Nebula’s Vision

**Nebula** addresses these challenges by leveraging Nibiru's unique capabilities and introducing innovative features:

* Enhanced Capital Efficiency: Employs machine learning algorithms for dynamic collateralization and interest rates, optimizing capital utilization without compromising risk management.
* Cross-Chain Interoperability: Utilizes Nibiru’s IBC protocol to enable seamless lending and borrowing across multiple blockchains, including Ethereum, Cosmos, and others, unlocking isolated liquidity and expanding market opportunities.
* Scalability and Affordability: Benefits from Nibiru’s high-speed, low-cost infrastructure, ensuring low transaction fees and fast processing times, making the protocol accessible to a wider audience.
* Advanced Security Protocols: Implements formal verification of smart contracts, zero-knowledge proofs for privacy-preserving transactions, and multi-layered encryption, enhancing protocol security and user confidence.
* Decentralized Governance: Utilizes quadratic voting and delegated governance to empower the community, preventing centralization of power and fostering a more democratic decision-making process.

## Mission Statement

**Nebula**'s mission is to democratize access to decentralized lending by creating a secure, scalable, and user-centric ecosystem. The protocol aims to foster financial inclusion, enabling individuals and institutions to unlock the full potential of their digital assets without intermediaries, while contributing to the evolution of a more interconnected and efficient global financial system.
