“…In this study, intelligent consensus mechanisms such as throughput and incentives in the model for the service chain need to be further improved [ 39 , 40 ]. Meanwhile, as an emerging technology in the digital asset sector, the circular liquidity cross-chain model has a broader outlook.…”

Blockchain cross-chaining is about interconnectivity and interoperability between chains and involves both physical to virtual digital aspects and cross-chaining between digital networks. During the process, the liquidity transfer of information or assets can increase the use of items with other chains, so it is worth noting that the enhancement of cross-chain liquidity is of great practical importance to cross-chain technology. In this model, Layerzero is used as the primary secure cross-chain facility to build a full-chain identity by unifying NFT-distributed autonomous cross-chain identity IDs; applying super-contract pairs to enhance cross-chain liquidity; and initiating a dynamic transaction node creditworthiness model to increase the security of the cross-chain model and its risk management. Finally, by verifying three important property metrics timeliness is improved by at least 18%, robustness is increased by at least 50.9%, and radius of convergence is reduced by at least 25%. It is verified that the liquidity cross-chain model can eliminate the authentication transition between hierarchies while saving the cross-chain time cost, as a way to truly realize the liquid interoperability between multiple chains of blockchain.

“…Поскольку лежащая в основе токенизации активов технология блокчейн является прозрачной, это позволяет инвесторам видеть всю историю движения активов и принимать в связи с этой прозрачностью свои бизнесрешения. Но при этом принято считать, что данная прозрачность движения активов должна обязательно сопровождаться анонимностью передаваемых транзакций и в контексте сross-chain interoperability (Yin et al, 2023). Иначе говоря, анонимная передача (или обмен) активов должна скрывать личности пользователей, участвующих в транзакции.…”

Objective: literature review and basic characteristics of the asset tokenization; clarification of the types of token classification; identification of the stages of modeling the asset tokenization; analysis of applications of decentralized finance ecosystem protocols; study of the opportunities and systemic advantages of asset tokenization; presentation of the problems arising in the asset tokenization; analysis of the factors of asset tokenization efficiency growth.Methods: the article uses empirical, historical, logical, country-specific, corporate, comparative and statistical methods of economic analysis to study the peculiarities of the asset tokenization development in the digital transformation of modern economy.Results: the basic characteristics of the asset tokenization are disclosed; the types of standardized tokens involved in the asset tokenization are defined; the stages of the asset tokenization development are considered; the options of using decentralized finance applications under asset tokenization are shown; the opportunities of tokenization through the new forms of investment, increased financial accessibility, transparency and componentization of tokenized assets are studied; the problems of tokenization are analyzed; the factors of asset tokenization efficiency growth under the cross-chain compatibility of different types of blockchains are analyzed. Scientific novelty: the article shows that asset tokenization is a process of accounting and asset management transformation, in which each asset is represented in the form of a programmable digital token; tokenization is a new form of creating additional liquidity by expanding the circulation of idle illiquid assets. Tokenization guarantees greater transparency regarding the rights to real assets and the history of ownership of these rights; it contributes to transaction efficiency by reducing transaction costs, including costs associated with management, token issuance and possible forms of intermediation. By accessing the applications of the DeFi ecosystem, it allows the expansion of financial market potential through the fragmentation and compartmentalization of tokenized assets. All the challenges in the asset tokenization are related to the blockchain trilemma, where decentralization, security and scalability cannot be implemented together. The blockchain trilemma is now becoming a set of possible trade-offs that can preserve all three properties of the blockchain, but at different levels of compatibility. To form a set of possible trade-offs, it is necessary to develop a theory of interoperability, which should be built on the compatibility of factors such as anonymity and privacy, security and preservation of rights to tokenized assets.Practical significance: the main provisions and conclusions of the article can be used: to develop scenarios for the asset tokenization development under the digital transformation of modern economy; to analyze the applications of the decentralized finance ecosystem protocols; to increase the efficiency of asset tokenization under the cross-chain compatibility of different types of blockchains; to study additional opportunities and systemic advantages as a result of fragmentation and compatability of tokenized assets; to study the problems arising in the asset tokenization; and to search for additional growth factors for the asset tokenization efficiency.

“…If so, it will set it to 0, recount it and continue to wait; otherwise, the master node will collect the transaction transaction packaged into chunks and verify it with the consensus node, and will broadcast the result of this time to the supervisory nodes and propagation nodes only after both of them have confirmed the transaction in the previous round. (8) The master node counts the feedback and after confirming the consensus, it will send a message to notify the supervisory node, which will calculate and update the credit value of each node and open the next round of consensus at the same time.…”

“…Therefore, new technologies are needed to achieve the transformation from centralized to distributed transaction models to cope with the microgrid power trading market [3,4]. Blockchain, as an emerging decentralized technology, can effectively solve the problems of the traditional centralized transaction model, such as the vulnerability to attacks and inability to guarantee user privacy, by virtue of its features, such as non-tampering, anonymity, traceability, and autonomy [5][6][7][8]. However, it is known from the existing research that a microgrid power trading system using blockchain technology has problems such as low throughput and high delay, which cannot meet the demands of real-time trading [9,10].…”

Currently, in the blockchain-based distributed microgrid trading system, there are some problems, such as low throughput, high delay, and a high communication overhead. To this end, an improved Practical Byzantine Fault Tolerance (PBFT) algorithm (CE-PBFT) suitable for microgrid power trading is proposed. First, a node credit value calculation model is introduced, and nodes are divided into consensus, supervisory, and propagation nodes according to their credit values, forming a hierarchical network structure to ensure the efficiency and reliability of consensus. Secondly, the consensus process is optimized by adopting a segmented consensus mechanism. This approach calculates the consensus rounds for nodes and selects the methods for node-type switching and consensus based on these calculations, reaching dynamic changes in node states and credit values, effectively reducing the communication overhead of node consensus. Finally, the experiments show that compared with the IMPBFT and PBFT algorithms, the CE-PBFT algorithm has better performance in throughput, delay, and communication overhead, with a 22% higher average throughput and 15% lower average delay than the IMPBFT algorithm and a 118% higher average throughput and 87% lower average delay than the PBFT algorithm.
