In this paper, the role of a matchmaker in transferring climate technologies to developing countries was explored from the perspective of open innovation. As the United Nations Framework Convention on Climate Change’s Technology Mechanism, the Climate Technology Centre and Network (CTCN) has strong convening power amongst the stakeholders who are responsible for climate actions in their country. Our research identified that the CTCN has successfully provided “4 openness” models (open network, open request for Technical Assistance, open technology transfer and finance, and open knowledge for the public) to global partners through its technical assistance (TA) services. Then, on the basis of previous empirical Technical Assistance data and network management a new open innovation model was proposed by considering the CTCN matchmaking activities with key stakeholders (innovation networks) during the climate technology transfer processes. This model explains that the role of the CTCN and innovation networks such as academia/research institutions, governments, and the private sector can be interpreted as outside-in innovation at the first technology outsourcing stage, coupled innovation at the second technology research, development, and demonstration (RD&D) stage, and inside-out innovation at the third technology diffusion stage. Moreover, further matchmaker’s approaches for supporting developing countries to establish a conducive and sustainable innovation system were suggested for the extension of our new model.

“…Given that the financial sector is undoubtedly the most regulated, as a pillar of the functioning of the economy, based on public trust, the development of all technologies with application in this industry appears to be of considerable interest to policymakers and regulators [1,2,44]. The incredible ability to speed up transactions, to connect users (potential lenders and borrowers) without adequate reliability checks, along with the decentralization of systems, represent essential challenges and as many concerns for the future of Fintech.…”

“…It can be considered and presented from different perspectives as it is a sub-category of technologies in which the ledger is structured as a chain of blocks containing transactions and whose validation is entrusted to a consensus mechanism, distributed on all nodes of the network in the case of permission-less or public blockchains or on all nodes the nodes that are authorized to participate in the transaction validation process to be included in the register in the case of "permissioned" or private blockchains. The main characteristics of blockchain technologies are the immutability of the register, transparency, traceability of transactions, and security based on cryptographic techniques [44][45][46].…”

Among the hot research topics, Fintech is leading the trend in terms of the newest technology applications. The relatively new emerging paradigms in various sciences, such as geometry (fractals), physics (quantum), and database systems (distributed ledger—blockchain), seem to potentially contribute to a greater shift in the framework of the finance industry, bringing also some concerns (cyber-threats). Consistent and extensive investigation of the reasonable potential impact of these new models (and their underlying technologies) is performed, and then tested through a SWOT analysis, as the main objective of this research. Threats and opportunities are always intrinsically driven by the introduction of technological advancements (revolutions). This research confirms that information availability and the increasing interconnection of crosswise applications of each discovery to the different fields of science is determining the rapid succession of revolutions identified by evident large shifts in economic paradigms. The growing computing capacity and the development of increasingly powerful predictive software are leading to a competitive, extremely dynamic, and challenging system. In this context, as shown by history, there is a high possibility of market concentration in which, however, only a few corporations—digital giants—can afford to develop these technologies, consolidating their dominance.

Reputation-Driven Dynamic Node Consensus and Reliability Sharding Model in IoT Blockchain

et al. 2022

The Internet of Things that links the cyber and physical worlds brings revolutionary changes to society, however, its security and efficiency problems have not been solved. The Consortium Blockchain + IoT is considered to be an effective solution. The IoT blockchain network’s demand for transaction processing speed is gradually increasing. The throughput problem of the blockchain needs to be solved urgently and the security problem of transaction processing that comes with it. To solve the above problems, this paper proposes a reputation-driven dynamic node security sharding consensus model (RDSCM) in the blockchain, which consists of two parts: a reputation-driven node to eliminate PBFT (RE-PBFT) and a reputation-driven node cross reconfiguration sharding scheme (NCRS). The RE-PBFT eliminates abnormal nodes in the consensus network and reduces the probability of abnormal nodes becoming master nodes. NCRS improves the blockchain throughput while ensuring sharding reliability. Finally, the experiment proves that RE-PBFT can identify abnormal nodes and remove them in a short time. NCRS can effectively guarantee the reliability of sharding, and the transaction processing efficiency has been greatly improved after sharding.
