“…Currently, various IoT applications are being envisaged and prototyped to allow decentralized IoT-based supply chains to guarantee various properties and to support transaction non-repudiation. One such application using blockchains to secure a ''field-to-fork'' food-chain is being prototyped by project SOFIE 30 (Secure Open Federation for Internet Everywhere) [58]. The information recorded in blockchains includes food production and storage data, acquired through diverse types of sensors.…”

While blockchains and more generally distributed ledger technologies (DLTs) are passing over their hype curve peak, their shortcomings are becoming more apparent. One relatively recent approach to address their performance, scalability, privacy, and other problems are to use multiple different DLTs instead of relying on just one. While there are no really established standards for combining several DLTs, a few repeating patterns can be observed. In this paper, we present a survey of interledger approaches, discussing and comparing their underlying mechanisms. A shared motivation for all of the discussed interledger solutions is to move away from the ''one chain rules them all'' model to one that allows the interconnection of multiple ledgers, with different features and advantages, while also supporting innovation. The interledger approaches discussed in this survey include 1) atomic cross-chain transactions, 2) transactions across a network of payment channels, 3) the W3C Interledger Protocol (ILP), 4) bridging, 5) sidechains, and 6) ledger-of-ledgers. The approaches are compared according to whether they support the transfer or the exchange of value, their interconnection trust mechanism, complexity, scalability, and transaction cost. INDEX TERMS Atomic swaps, blockchain, cross-chain transactions, distributed ledger technologies (DLTs), hash-locks, interledger protocol (ILP), sidechains, time-locks.

“…Several techniques exist, and are being researched, on how to perform interledger operations securely with full guarantees of transaction completion across multiple ledgers. For example, [61] defines six different categories of interledger techniques: atomic cross-chain transactions, sidechains, bridging, ledger-of-ledgers, payment channels, and layered value transfer protocols. In other cases, the interledger operations may carry financial risks, but the protocol is designed to make any nonconformance auditable [62].…”

The upsurge of Industrial Internet of Things is forcing industrial information systems to enable less hierarchical information flow. The connections between humans, devices, and their digital twins are growing in numbers, creating a need for new kind of security and trust solutions. To address these needs, industries are applying distributed ledger technologies, aka blockchains. A significant number of use cases have been studied in the sectors of logistics, energy markets, smart grid security, and food safety, with frequently reported benefits in transparency, reduced costs, and disintermediation. However, distributed ledger technologies have challenges with transaction throughput, latency, and resource requirements, which render the technology unusable in many cases, particularly with constrained Internet of Things devices.To overcome these challenges within the Industrial Internet of Things, we suggest a set of interledger approaches that enable trusted information exchange across different ledgers and constrained devices. With these approaches, the technically most suitable ledger technology can be selected for each use case while simultaneously enjoying the benefits of the most widespread ledger implementations. We present state of the art for distributed ledger technologies to support the use of interledger approaches in industrial settings.

With the Internet of Things (IoT), Things are expected to live in different "domains" and "contexts" during their lifetime. Information generated by and associated with Things should be manageable by multiple, diverse stakeholders accordingly. Moreover, the scope of the information related to Things can range from private and confidential to public and auditable. Identification, security, and interoperability in this vivid environment are expected to be challenging. In this paper we discuss how smart contracts and blockchain technologies create the potential for a viable solution. To this end, we present smart contract-based solutions that improve security and information management, we identify new opportunities and challenges, and we provide security recommendations and guidelines.
