These cross-chain protocols enable secure interoperability between multiple distinct blockchains. Security requires that the target chain has the ability to verify whether cross-chain messages have been finalized on the source chain. Existing cross-chain protocols first synchronize source chain block headers to the target chain and validate them, then verify cross-chain messages included in the header's commitment value using native accumulators, like a Merkle tree. Cross-chain verification incurs significant on-chain overhead. Existing solutions primarily focus on optimizing header verification, while neglecting verification overhead for messages. It is worth noting that as the number of on-chain states increases, the number of elements in the accumulator multiplies, leading to a larger proof size that escalates message verification overhead on the target chain. To reduce message verification overhead on the target chain, we present CAVer. It removes non-cross-chain states from accumulators to minimize message proof size. CAVer incorporates three schemes: Fill-Weak, Fill-Mid, and Fill-Pro. Fill-Weak abandons blockchain's native accumulators by creating a new contract-based compacting accumulator exclusively for cross-chain messages on the source chain. Based on Fill-Weak, Fill-Mid, and Fill-Pro employ block-isolation and target-isolation, respectively, to further reduce verification overhead. Additionally, we design the algorithm <span>AppendAndTailor</span> to reduce storage cost on the source chain. It aims at trimming historical states when accumulating cross-chain messages. Evaluations on Ethereum-like blockchains demonstrate that CAVer reduces message verification overhead on the target chain by 76% compared to the existing state-of-the-art scheme.</div></div>","PeriodicalId":53141,"journal":{"name":"Blockchain-Research and Applications","volume":"7 5","pages":"Article 100381"},"PeriodicalIF":6.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149211224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although electronic health record (EHR) standards such as health level 7 fast healthcare interoperability resources (HL7 FHIR) and OpenEHR provide frameworks for data consistency and interoperability, concerns persist regarding the privacy and security of sensitive patient information, particularly in compliance with regulations. Existing solutions often store only hashed representations of data on blockchain nodes, making direct on-chain validation impossible and increasing the risk of invalid or malicious data entering the system. This paper introduces maximize, encrypt, prove, comply and adapt (MEPCA), a novel blockchain-based framework designed to enhance on-chain EHR data processing using cryptographic techniques. The model incorporates an innovative method to generate cryptographic proofs of data validity, enabling direct on-chain verification of hash digests. We present practical use case implementations and perform a technical evaluation of a fully on-chain MEPCA approach within the HL7 FHIR ecosystem. Our analysis examines the processing time of the hash proof algorithm, comparing it with existing methods based on transactions per second (TPS), latency, and computational efficiency in a multi-host network environment. The experimental results show that the MEPCA framework achieves a maximum of 83.2 TPS, with a latency below 1.5 s and the hash-proof computation taking 1.6 ms. Our primary contribution is to demonstrate viable healthcare scenarios for a fully on-chain approach, providing strategic guidance for the adoption of decentralized solutions in healthcare through technical evaluation and real-world applications.</div></div>","PeriodicalId":53141,"journal":{"name":"Blockchain-Research and Applications","volume":"7 5","pages":"Article 100373"},"PeriodicalIF":6.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149211212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They aim to address the blockchain scalability trilemma by offering low transaction fees and nearly instantaneous processing confirmation times.

However, it can disclose identities and exchange histories, making it vulnerable to wormhole attacks. Additionally, current solutions rely either on the ideal anonymous communication channel assumption or fail to provide complete path privacy protection. In this paper, we propose the efficient multi-party conditional payment flow (EMCPF) protocol. It is a lightning network-compatible and privacy-preserving payment protocol designed to protect all user identities, reduce collateral locking time, and resist wormhole attacks. Moreover, it does not rely on ideal routing assumptions and instead employs layered encryption. Security analysis conducted under the universal composability model shows that no information can be disclosed if there is at least one honest user within the payment path. Functional analysis was also provided to support our privacy and security claims. We also performed theoretical analyses that compare EMCPF with other existing payment protocols based on complexity, efficiency, and the phases involved.

So, the integration of blockchain can enhance data integrity, transparency, and security while eliminating trusted third parties. However, these characteristics make blockchains difficult to scale and typically involve high costs for a large number of transactions. It makes it difficult to manage large amounts of data, which are generally produced in IIoT environments. Some recent results have demonstrated how the use of private blockchains can improve the issues of scalability and transaction costs.
