Research Objective: The study investigates the feasibility and benefits of incorporating common transactional behaviors, typically handled by smart contracts, into the core blockchain layer as native transactions using a declarative model.

Methodology: The researchers developed a formal declarative blockchain transaction model and implemented it as SmartchainDB, an extension of the BigchainDB platform. They designed new transaction types and validation algorithms, focusing on functionalities common in decentralized marketplaces. A comparative performance evaluation was conducted against a traditional smart contract implementation (ETH-SC) using a reverse auction marketplace scenario.

Key Findings:

• SmartchainDB demonstrated significantly lower latency across various transaction types compared to ETH-SC, especially for larger transaction sizes.
• The throughput of SmartchainDB remained consistent with increasing transaction size, while ETH-SC suffered a decline.
• Both systems exhibited stable latency with an increasing number of validator nodes.

Main Conclusions:

• Declarative blockchain transactions offer a viable and more efficient alternative to smart contracts, particularly for complex applications.
• Integrating common transaction types as native functions in the blockchain layer can significantly enhance performance and scalability.
• The declarative approach simplifies transaction specification, potentially improving blockchain usability for non-experts.

Significance: This research contributes to the field of blockchain technology by addressing key limitations of smart contracts related to performance, scalability, and usability. The proposed declarative approach and SmartchainDB implementation offer a promising direction for developing more efficient and user-friendly blockchain applications.

Limitations and Future Research: The study focuses on a specific application scenario (reverse auction marketplace) and a limited set of transaction types. Further research is needed to explore the generalizability of the approach to other application domains and a wider range of transaction types. Additionally, investigating the security implications of the proposed model in depth is crucial for its practical adoption.

How can the security and resilience of declarative blockchain transactions be further enhanced to mitigate potential vulnerabilities in real-world deployments?

Enhancing the security and resilience of declarative blockchain transactions for real-world deployments requires a multi-faceted approach addressing potential vulnerabilities inherent in both the design and implementation:
1. Robust Formal Verification:

Extend formal models: The existing formal model, while a good starting point, should be expanded to encompass a wider range of potential attack vectors and edge cases. This includes formally defining the semantics of all new transaction types and their interactions.
Automated theorem proving: Employ automated theorem provers to rigorously verify the correctness and security properties of the declarative transaction model. This helps ensure that the defined conditions and constraints are logically sound and effectively prevent unintended behavior.
Formal verification of implementation: The implementation of the transaction validation algorithms and the underlying SmartchainDB platform should undergo rigorous formal verification to guarantee their adherence to the formally defined model.
2. Enhanced Security Mechanisms:

Advanced cryptography: Explore the integration of more sophisticated cryptographic techniques, such as threshold signatures and zero-knowledge proofs, to further enhance the security and privacy of sensitive transaction data.
Secure escrow mechanisms: Implement robust and formally verified escrow mechanisms to securely manage assets during nested transactions, preventing potential losses or fraudulent activities, especially in case of failures.
Time-based security: Incorporate time-locks and other time-based security mechanisms to mitigate risks associated with long-lived transactions and potential race conditions in a distributed environment.
3. Resilience and Fault Tolerance:

Enhanced failure recovery: The current Non-locking Transaction Execution approach, while addressing some failure scenarios, should be further strengthened to handle a wider range of potential failures, ensuring data integrity and consistency.
Redundancy and replication: Implement redundancy and replication mechanisms for critical components of the SmartchainDB infrastructure, such as the task queue and the recovery log, to ensure continuous operation even in the event of node failures.
Formal analysis of failure modes: Conduct a comprehensive formal analysis of potential failure modes and their impact on the system to identify and address vulnerabilities, ensuring graceful degradation and recovery.
4. Ongoing Security Audits and Best Practices:

Regular security audits: Conduct regular and comprehensive security audits by independent third-party experts to identify and address potential vulnerabilities in the codebase, infrastructure, and operational procedures.
Community involvement: Foster a culture of security awareness and encourage community involvement in identifying and reporting potential issues through bug bounty programs and open-source contributions.
Adherence to best practices: Strictly adhere to industry best practices for secure software development, deployment, and maintenance, including code reviews, penetration testing, and vulnerability management.
By implementing these measures, the security and resilience of declarative blockchain transactions can be significantly enhanced, paving the way for their wider adoption in real-world deployments where trust and reliability are paramount.

Could a hybrid approach, combining the flexibility of smart contracts with the efficiency of declarative transactions for specific operations, offer a more balanced solution?

Yes, a hybrid approach combining the flexibility of smart contracts with the efficiency of declarative transactions presents a compelling solution for blockchain applications. This approach leverages the strengths of both paradigms, offering a balanced trade-off between expressiveness and performance.
Here's how a hybrid model could work:

Identify Core Transactional Patterns: Analyze common transactional behaviors and workflows within specific application domains to identify patterns suitable for declarative representation. These patterns should be frequent, well-defined, and have predictable performance requirements.
Design Declarative Transaction Types: Develop specialized declarative transaction types, similar to those proposed in SmartchainDB, to handle these identified core patterns. These types should encapsulate the necessary logic and constraints, enabling efficient validation and execution.
Integrate with Smart Contract Platform: Integrate these declarative transaction types into the existing smart contract platform, allowing developers to seamlessly incorporate them into their smart contracts. This integration could involve extending the smart contract language or providing libraries and APIs for interacting with the declarative transaction layer.
Smart Contracts for Complex Logic: Utilize smart contracts for implementing complex business logic, custom functionalities, and scenarios that fall outside the scope of predefined declarative transaction types. This allows developers to retain flexibility for handling unique or evolving requirements.
Seamless Interoperability: Ensure seamless interoperability between smart contracts and declarative transactions, allowing them to interact and exchange data efficiently. This might involve mechanisms for triggering declarative transactions from within smart contracts and vice versa.

Benefits of a Hybrid Approach:

Enhanced Performance: Leverage the efficiency of declarative transactions for common operations, reducing the computational overhead and latency associated with smart contract execution.
Improved Scalability: Offload frequently occurring transactional patterns to the declarative layer, freeing up resources and improving the overall scalability of the blockchain platform.
Reduced Development Complexity: Simplify the development process for common use cases by providing pre-built, efficient declarative transaction types, reducing the need for custom smart contract code.
Increased Security: Benefit from the formal verification and security guarantees offered by the declarative transaction model for core operations, reducing the attack surface and potential vulnerabilities.
Flexibility for Customization: Retain the flexibility of smart contracts for implementing complex logic and custom functionalities, ensuring adaptability to evolving business needs.
By strategically combining the strengths of both approaches, a hybrid model can unlock new possibilities for blockchain applications, enabling a wider range of use cases that demand both expressiveness and performance.
