An agreement method of a block in a blockchain network by a chair node includes: receiving, from a plurality of congress nodes in a congress, information on an exceptional situation which occurred during agreement processes of a block; transmitting an empty block agreement start message including information on the exceptional situation and verification data for the exceptional situation to the plurality of congress nodes; generating a candidate empty block which does not include a transaction when receiving a delegate request message from at least two congress nodes among the plurality of congress nodes and transmitting the candidate empty block to committee nodes; and generating a final empty block when the candidate empty block is verified by the committee nodes and transmitting the final empty block to all nodes in the blockchain network is provided.

Method and apparatus for agreement of block in blockchain network

This disclosure relates to a method of preparing a lithium compound that includes preparing a lithium phosphate, mixing the lithium phosphate with sulfuric acid to obtain a mixture, converting the lithium phosphate into lithium sulfate through a reaction in the mixture, and separating the lithium sulfate in a solid phase, wherein in the step of converting the lithium phosphate into lithium sulfate through the reaction in the mixture, a sum concentration ([P+S] mol/L) of phosphorus (P) and sulfur (S) in a liquid phase of the mixture is greater than or equal to 5 mol/L.

Method of preparing lithium compound

A block consensus method of a computing device is provided. The computing device receives a delegate request message including transaction hashes from each of a plurality of nodes, generates a prepared block including transaction hashes based on the delegate request message, and transmits a prepare message including the prepared block to the nodes. The computing device receives a commit message including a proof of consensus on a validity of the prepared block from the nodes, and transmits a reply message including a final block decided based on the commit message.

Method for block consensus and method for managing transaction state

It is introduced that a device of manufacturing lithium sulfate comprising: a reaction body in which a reaction of lithium phosphate and sulfuric acid is performed, the reaction body being divided into an upper space and a lower space; a pressurizer for applying pressure to the inside of the reaction body; a stirrer disposed in the upper space for stirring the lithium phosphate and sulfuric acid to produce a mixture containing lithium sulfate and phosphoric acid; and a filter disposed inside the reaction body and separating the filtrate containing the phosphoric acid into the lower space by filtering the mixture.

Manufacturing apparatus for lithium sulfate and manufacturing method therefor

The present invention relates to a novel isoquinoline derivative, a preparing method thereof, and a pharmaceutical composition for preventing or treating autophagy related diseases containing the same as an active ingredient. The novel isoquinoline furanone derivative according to the present invention is capable of regulating autophagy activity, and thus, by using this derivative as an active ingredient, there is a useful effect that can be used as a pharmaceutical composition for preventing or treating autophagy-related diseases such as neurodegenerative diseases, cancer, metabolic diseases, inflammatory diseases or melanogenesis-related diseases, a health functional food composition for ameliorating thereof, or a cosmetic composition with a whitening function.
