The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to use blockchain to facilitate business transactions. Industry analysts estimate there is $3 T of value locked in B2B processes that could benefit from specific types of transactions. This project proposes a new architecture to enable different types of transactions and across blockchain protocols, while maintaining data security, privacy, and other restrictions. This SBIR Phase I project proposes to develop a modular architecture to verify state transfers across different blockchains (including those running different underlying protocols). The research objective is to explore new architectures, including using an interop coordinator based on state commitments submitted by decentralized groups of interop agents. The interop coordinator will then validate their finality according to the consensus specifications of the submitting chain. The interop coordinator will act as the broker for proof requests and responses, as decentralized interop agents from one chain submit requests for proof of a particular transaction in another chain. The prover of the target chain will build a cryptographic proof and forward it to the interop coordinator, to relay the response to the requesting chain. Verification will be conducted by the requesting agent using various methods to be investigated as part of this research. The proposed project approach is distinguished from other interoperability projects in its support for heterogeneous blockchain protocols and the support for arbitrary types of transactions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力是使用区块链来促进商业交易。行业分析师估计，B2B流程中有$ 3的价值，可以从特定类型的交易中受益。该项目提出了一种新的体系结构，以启用不同类型的交易和跨区块链协议，同时维护数据安全性，隐私和其他限制。这个SBIR I阶段项目建议开发一个模块化体系结构，以验证跨不同区块链（包括运行不同基础协议的那些）的状态转移。研究目标是探索新的体系结构，包括根据分散的Interop代理人提交的国家承诺使用Interop协调员。然后，Interop协调员将根据提交链的共识规范来验证其终结性。 Interop协调员将充当证明请求和响应的经纪人，因为来自一条链的分散式Interop代理提交了另一个链中特定交易的证明请求。目标链的供奉献者将建立一个加密证明并将其转发给Interop协调员，以将响应转换为请求链。请求代理将使用各种方法进行验证，以作为本研究的一部分进行研究。 拟议的项目方法与其他互操作性项目在支持异质区块链方案和对任意类型交易类型的支持方面有所区别。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的审查标准通过评估来支持的。
