“…There are multiple trustless and privacy securing bridging solutions such as Falazi et al [17], A. Xiong et al [34], Horizon [23], Stone D. [31], and Bridging Sapling [29]. These solutions, integrated into the Public Connectors category, are either focused on permissionless blockchains supporting cryptocurrencies or do not have working implementations of the protocols.…”

“…We also discard solutions that require both ledgers to have access to each other (e.g. SPV-like solutions), or that allow any user to become a bridging validator given the permissioned nature of our use-case (e.g., a group of validators running a consensus mechanism in order to accept/reject a cross-chain transaction, where anyone can run a node [34]).…”

“…Each Cactus Node can be composed of multiple API Servers, hence our solution comprises two (Figure 1), each targeted to a different side of the bridge. We make use of both the Fabric and the Besu ledger connectors 34 as a means to access the ledgers; IPFS connectors allowing communication with an IPFS network that, as explained before, acts as decentralized log storage for integrity, accountability, and auditability purposes; finally, the ODAP/SATP business logic plugin 5 . The ODAP/SATP plugin acts as our gateway and exposes an API that is accessible to the end users to trigger bridging operations -bridging out or bridging back CBDC.…”

<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 is an important missing piece in general. In this paper, we leverage an asset transfer protocol, ODAP/SATP, to define an extendable and dependable blockchain interoperability middleware that can bridge CBDC from Hyperledger Fabric to EVM-based permissioned blockchains. The key interoperation enabler in the solution is a shared asset definition enforced by both sides of the bridge, accompanied by a mapping between Fabric Identities and Ethereum addresses for Identity management. We implement our design for the CBDC use case utilizing Hyperledger Cactus. Through a preliminary performance evaluation, we show that the underlying ledgers heavily influence the latency of the solution, not the bridging components.</p>

The metaverse is a virtual environment that combines the real and digital worlds through technological and social structures. It heralds a novel paradigm in internet applications and societal engagement by weaving together diverse cutting‐edge technologies to facilitate a virtual representation of the tangible world. Within the metaverse, the facets of economy, culture, and other dimensions are fully documentable, trackable, and quantifiable, largely owing to the capabilities of blockchain technology. Nonetheless, the transactional volume within the metaverse is typically substantial, posing challenges for a singular blockchain platform in terms of efficiency and support capacity. Consequently, a multi‐blockchain infrastructure becomes essential to underpin the economic fabric of the metaverse. Enabling the collaborative operation of multiple blockchain platforms, specifically achieving the seamless transfer of value across different blockchain ecosystems, has emerged as a critical challenge. To address this challenge, this paper introduces a cross‐chain protocol predicated on a multi‐role notary system designed to facilitate inter‐blockchain value transfers. The protocol specifies the functions of different entities within the notary framework, allocating specific duties to notaries, committees, and a leader. It also promotes mutual oversight among notaries to sustain a dynamic and equitable group structure. Furthermore, an incentive mechanism is proposed to motivate committee members toward prompt and judicious decision‐making regarding votes. Based on experiments conducted on the Ethereum platform, our proposed solution exhibits a 75% reduction in transaction time compared to Ethereum's transaction confirmation time.
