Due to rapid industrialization and urbanization, marine pollution becomes more and more serious in recent decades. Excess nutrients in coastal water cause eutrophication and red tide problems;while toxic chemicals pose harmful effects to our environments and human health. Mangroves, located between land and sea, have long been used as convenient waste dumping sites and inadvertently received untreated wastewater from various sources. The special properties of mangroves, such as high primary productivity and large nutrient demand, rapid litter decomposition and nutrient cycling, active and diverse microorganisms associated with sediments and roots suggest that mangroves have self-purification ability. Many people actually claimed that mangroves could be used to purify pollutants from wastewater and remedy contaminated sediment;however, systematic and scientific research on these areas is still rare. In the past ten years, according to a "quick search" using "science Direct" , almost 1,000 sCI papers were published in "mangroves", but only 21 were on ’mangrove and sewage", and less than 10 were on "mangrove and bioremediation". It is clear that more research is needed to understand the significance of mangrove ecosystems as pollution control measures. The use of constructed wetland as wastewater treatment facility has attracted more and more attention in the past three decades, especially in North America, Europe and recently in Asia. Thousands of constructed wetland treatment systems of various sizes and capacities have been built. Plants such as common reeds, cattails, bulrush, etc. have been used. However, these plants require frequent harvesting which may make affect the consistency of the treatment efficiency. Disposal of plant materials is another operation problem. Mangroves, perennial woody plants, do not require any harvesting, their high productivity and nutrient demand, and their salinity tolerance actually make them good alternatives.

snapshotPrune: A Novel Bitcoin-Based Protocol Toward Efficient Pruning and Fast Node Bootstrapping

引用

Tsinghua science and Technology 2024年第4期29卷 1037-1052页

作者： Pengfei Huang Xiaojun Ren Teng Huang Arthur sandor Voundi Koe Duncan s wong Hai Jiang Institute of Artificial Intelligence and Blockchain Guangzhou UniversityGuangzhou 510006China Institute of Artificial Intelligence and Blockchain Guangzhou UniversityGuangzhou 510006Chinaand also with Pazhou LabGuangzhou 510330China

Node synchronization is essential for the stability of the Bitcoin network. Critics have raised doubts about the ability of a new node to quickly and efficiently.s.nchronize with the Bitcoin network and alleviate the storage pressure from existing full nodes to stockpile new data. Basic pruning and other techniques have been explored to address these concerns but have been insufficient to reduce node synchronization delay and effectively.s.ppress the growth of synchronized data. In this study, we propose snapshotPrune, a novel pruning and synchronization protocol that achieves fast node bootstrapping in the Bitcoin blockchain. Real Bitcoin historical data are leveraged to measure the synchronization time and monitor the network traffic during node bootstrapping. The protocol requires data downloads that are 99.70% less than Bitcoin Core, 81% less than CoinPrune, and 60% less than snapshotsave, thereby.s.ving 97.23% of download time. Findings show that the proposed design enhances the storage efficiency and reduces the node synchronization delay compared with existing techniques. We hypothesize that the efficiency of this protocol increases with the block height.
