Ineffective data management practices pose serious issues to individuals and companies, e.g., risk of identity theft online exposure. Self-sovereign (SSI) is a new approach that ensures users have full control their personal data. In this work, we alleviate breach user privacy problems by showing how SSI can fit within the context established enterprise access technologies. light recent endeavors, explore use decentralized identifiers, verifiable credentials, blockchains support SSI. We...

Entrepreneurs, enterprises, and governments are using distributed ledger technology (DLT) as a component of complex information systems, therefore interoperability capabilities required. Interoperating DLTs enable network effects synergies, similarly to the rise Internet, it unlocks full potential technology. However, due novelty area, mechanisms (IMs) still not well understood, is studied in silos. Consequently, choosing proper IM for use case challenging. Our article has three...

A deep dive into blockchain interoperability: why it is needed, progress that has been made over the past decade, how currently deployed and used, likely paths of future development.

It is time for the legacy financial infrastructure to seamlessly connect with modern, decentralized infrastructure. Although it increasingly evident that finance (namely distributed ledgers) will coexist and complement infrastructure, also clear such interoperability efforts carry new risks concerns. In particular, managing range of heterogeneous (and not well-established) brings security, privacy, regulatory issues. The first step overcome some these challenges recognize in many deployment...

<p>The last few years have seen a steep increase in blockchain interoperability research. Most solutions connect public blockchains; hence, the main cross-chain use case is token transfer. By-design platform transparency, tamper-resistance, and auditability make blockchains an infrastructure candidate for Central Bank Digital Currencies (CBDCs), but bridging CBDCs important missing piece general. In this paper, we leverage asset transfer protocol, ODAP/SATP, to define extendable...

Recent years have witnessed significant advancements in cross-chain technology. However, the field faces two pressing challenges. On one hand, hacks on bridges led to monetary losses of around 3.1 billion USD, highlighting flaws security models governing interoperability mechanisms and ineffectiveness incident response frameworks. other users bridge operators experience restricted privacy, which broadens potential attack surface. In this paper, we present most comprehensive study date...

The maturing of blockchain technology leads to heterogeneity, where multiple solutions specialize in a particular use case. While the development different networks shows great potential for blockchains, isolated have led data and asset silos, limiting applications this technology. Blockchain interoperability are essential enable distributed ledgers reach their full potential. Such allow blockchains support transfer, resulting innovative applications. This paper proposes novel solution...

Purpose The complexity of business environments often causes organizations to produce several inconsistent views the same process (BP), leading fragmentation. BP view integration attempts an integrated from different model, facilitating management models. Design/methodology/approach To study trends integration, authors conduct extensive and systematic literature review summarize findings since 1970s. With a starting corpus 918 documents, this survey draws up inventory solutions used in...

<p>Blockchain interoperability conflates the need for distributed systems to communicate with third- party without existence of a canonical chain or orchestration layer. As there is not “a rule them all” (due reasons such as performance, privacy, and market forces), these rely on exchanging data value across network boundaries. Interconnected achieve higher than sum their parts, similar how Internet emerged set isolated Local Area Networks (LANs) - and, by force surprising synergies,...

Ecosystems of multiple blockchains are now a reality. Multichain applications and protocols perceived as necessary to enable scalability, privacy, composability. Despite being promising emerging area, we have been witnessing devastating attacks on cross-chain bridges that caused billions dollars in losses, no apparent solution seems emerge from the ongoing chaos. In this article, present our contribution minimizing bridge attacks, by monitoring <italic...

The field of blockchain interoperability plays a pivotal role in adoption. Despite these advances, notorious problem persists: the high number and success rate attacks on bridges. We propose Harmonia, framework for building robust, secure, efficient, decentralized cross-chain applications. A main component Harmonia is DendrETH, efficient zero-knowledge proof-based light client. DendrETH mitigates security problems by lowering attack surface relying properties proofs. instance this paper an...

Enabling blockchain-based digital asset exchanges requires blockchain interoperability capabilities. Although some solutions have been proposed in recent years, and crypto-currency transfers across legal jurisdictions are still an unsolved problem. To realize this vision, we propose Hermes, a fault-tolerant middleware that connects networks, enabling the transfer of data value jurisdictions. Hermes is based on Open Digital Asset Protocol (ODAP), protocol. utilizes novel mechanism called...

&lt;div&gt;&lt;div&gt;&lt;br&gt;&lt;/div&gt;&lt;div&gt;Decentralized ledger technology (DLT), in particular blockchain, is becoming ubiquitous today's society. Just the second quarter of 2021, centralized and decentralized exchanges had a volume around $600 billion. Enterprises are adopting this technology, following opportunity to expand new businesses. However, they need connect their existing systems processes blockchains securely reliably. Blockchain interoperability (BI) emerging as one...

&lt;p&gt;Distributed ledger technology (DLT) provides decentralized and tamper-resistant data storage, replicated among mutually untrusting participants. With the advancement of this technology, different privacy-preserving blockchains have been proposed, such as Corda, Hyperledger Fabric, Digital Asset's Canton. These distributed ledgers only provide \emph{partial consistency}, which implies that participants can view same differently. &lt;/p&gt; &lt;p&gt;A \emph{view} represents states a...

However, literature on this emerging technology is scarce not systematized, making it harder for practitioners researchers to understand field. In paper, we systematize aggregators, with a specific emphasis bridge aggregators. We present exhaustive analysis diverse array token...

Decentralized ledger technology (DLT) is becoming ubiquitous in today’s society. However, organizations need to connect their existing systems and processes blockchains (centralized, decentralized) securely reliably, sometimes also implying that they (decentralized, decentralized). This challenge known as blockchain interoperability. We put the case forward academia industry must propose evaluation frameworks for interoperability solutions address three modes. Those are data transfers, asset...

&lt;div&gt;The emergence of blockchain interoperability is reducing the risk investing in by avoiding vendor lock-in, leveraging interoperation, and providing migration capabilities. However, to fully unlock internet blockchains, it necessary provide enterprise mechanisms that allow service providers comply with different regulations, e.g., data privacy regulations. Each can be reached via a gateway, allowing interconnect value, services, enable self-sovereignty. To realize this vision, we...
