As of June 7, 2021, the block height has reached 674,000, which means that when querying historical data, hundreds of thousands of blocks may be traversed. Such a query method cannot meet the current query requirements. Level-DB is the mainstream database in the blockchain system, which ...
In this paper, we propose a novel blockchain architecture, which simplifies the verification in blockchain and is compatible with most consensus mechanism. We append backlinks in some blocks, such that blocks not only look like a chain but also like a binary tree. We also introduce a ...
The "summer shoulder" of the Kinergy 4S has been given a larger block structure and stepped tie bars between the blocks to meet the stringent requirements that apply when driving in dry, hot conditions. Ready, steady, Hankook; Get ready for winter now with the right tyres - or you could ...

RQ3: What are the main conceptual building blocks for the literature on humanitarian operations? To answer RQ1, the bibliometric co-citation analysis technique was selected, as it allows identification of the most influential works in the research field, resulting in a map of the main works of...
In [8], a P2P market that enables peers to trade locally with their neighborhoods has been developed based on Benders decomposition (BD). However, the VPPs were not taken into account. There are also practical examples of adopting P2P markets in local systems such as the blockchain-based ...
