“…As well, the work presented by (23) introduces the new concept Blockchain-as-a-Service and demonstrates based on a comparative study between SCs, services, and micro-services, that the integration between service-oriented context and blockchain technologies presents promising prospects. Moreover, the work presented by (24) described a full service-oriented architecture using smart contracts in Heterogeneous Blockchain platforms, by proposing a SC description language (SCDL) (6), and SC Invocation Protocol (SCIP) (25) which support the applicability of the service-oriented concept on the blockchain to facilitate its utilization, to foster reuse and increase cost-effectiveness. After this review, we assume that the service-oriented architecture for the blockchain represents a promising approach in which a smart contract is viewed as a service.…”

“…On the participative web, many service-oriented directories prove their efficiency to simplify the service inventory, IT management, and unified visibility for all services across the web (30) (17). Contrariwise to the web3 environment, the service orientation of the blockchain is still in the preliminary stage (24), (22). In fact, existing solutions try to search, explore, or index SC-produced transactions, or provide tokens to contracts directory (18), (19).…”

The slower than expected adoption rate of blockchain technology has highlighted that there are barriers due to the diversity of its applications and its users. To overcome this limitation and take full advantage of the novel technology, researchers from academia as well as industry are dedicated to find different solutions, where two or more blockchains can interact with each other. As a result, several interoperability solutions have presented themselves. To investigate the functionalities and underlying mechanisms of interoperable blockchain solutions, researchers have conducted several surveys by discussing the features and innovations of these methods. However, the existing surveys tend to focus on the architectural description of the interoperability solutions and completely overlook the most promising aspect of blockchain adaptability, namely the smart contract. This paper fills the gap by exploring the role of smart contracts in blockchain interoperability solutions. Our research has classified the existing interoperability solutions into three main categories: heterogeneous blockchains and homogeneous smart contracts, homogeneous blockchains and homogeneous smart contracts, heterogeneous blockchains, and heterogeneous smart contracts. To provide a systematic overview of the smart contracts used in blockchain interoperability, each category is further divided into subcategories by identifying the functionalities of the smart contract used. Based on our survey, a taxonomy is proposed to help classify the blockchain interoperability solutions. The interoperability solutions in each category are analyzed in-depth, and the results are presented in tabular format to illustrate the characteristics of the interoperability solutions in a meaningful way. Finally, a number of open issues and research directions are discussed to overcome the limitations and improve the performance of blockchain interoperability.INDEX TERMS Blockchain interoperability, smart contracts, chain code, cross chain transactions, sidechains, decentralized applications, cryptocurrency, digital assets.

“…Smart contracts can be programmed to emit events when certain conditions are met while executing their code. For example, a smart contract managing the provenance of a seafood product may be designed to emit an event when the product is moved from one handler to another, e.g., from the food processor to the end-distributor [22]. In addition, apart from applicationspecific events, blockchains can also emit other kinds of events interesting to external applications, e.g., events signifying (i) a successful processing and inclusion of a blockchain transaction, or (ii) the mining of a new block and appending it to the blockchain data structure.…”

Although historically the term serverless was also used in the context of peer-to-peer systems, it is more frequently associated with the architectural style for developing cloud-native applications. From the developer's perspective, serverless architectures allow reducing management efforts since applications are composed using provider-managed components, e.g., Database-as-a-Service (DBaaS) and Function-as-a-Service (FaaS) offerings. Blockchains are distributed systems designed to enable collaborative scenarios involving multiple untrusted parties. It seems that the decentralized peer-topeer nature of blockchains makes it interesting to consider them in serverless architectures, since resource allocation and management tasks are not required to be performed by users. Moreover, considering their useful properties of ensuring transaction's immutability and facilitating accountable interactions, blockchains might enhance the overall guarantees and capabilities of serverless architectures. Therefore, in this work, we analyze how the blockchain technology and smart contracts fit into the serverless picture and derive a set of scenarios in which they act as different component types in serverless architectures. Furthermore, we formulate the implementation requirements that have to be fulfilled to successfully use blockchains and smart contracts in these scenarios. Finally, we investigate which existing technologies enable these scenarios, and analyze their readiness and suitability to fulfill the formulated requirements.
