海外TECH	DEV Community	How does the Blockchain work?	https://dev.to/sarojvrc/how-does-the-blockchain-work-1mla	How does the Blockchain work Any idea about Blockchain Well Let s see first what Blockchain is and then we will discuss how it works Blockchain is a chain of data blocks stored in hundred or thousands or even millions of computers servers distributed over a wide geographical area It is a complete ledger that maintains a copy of all the credit debit transactions of digital assets It is based on decentralized technologies Eg Bitcoin is a great example of a blockchain application or we can say it works on decentralized principle That means when a new Node server is added to the bitcoin network it is impossible to modify or delete that node It works on a Peer to Peer PP network where each Peer acts as a server This diagram describes how a PP network is established in a blockchain network I m pretty sure now you have got an idea about blockchain and PP networks Great Now let s see how blockchain works Excited Me too We can define the blockchain as a system that allows the group of connected computers to maintain a single updated and secured ledger As we know blockchain is consists of a chain of blocks for every new transaction a new block needs to create So how a block node is created inside the blockchain network The very first step of creating a block is a user must request for a transaction to be added to the blockchain network also that transaction must include some required information like transaction id hash id timestamp etc After the transaction is verified the second step is a new block is created into the blockchain network but not added Once a block is created then it will broadcast to a PP Peer to Peer network PP networks also consist of blocks nodes Then the one PP node verifies the transaction After successfully verifying the transaction again moves to the next stage that is other nodes in that network also need to verify since all nodes are interlinked with each other and here comes to the last stage that isOnce the transaction is validated by other nodes in the network then the block is ready to go And now the block transaction is added to the existing blockchain network That is how the blockchain works I know it is kind of a bit confusing if you are new to blockchain But trust me once you understand it it will be fun for you Like me hahaCool Thanks for reading my article See you soon with a new topic Till then drink coffee and write code	2022-03-19 05:20:33
海外TECH	DEV Community	HasAllChildren	https://dev.to/lizardkinglk/hasallchildren-55lh	HasAllChildrenThe below is a function to check if an sub array consist of all the elements of a given array const hasChild array child gt const ruleA array undefined const ruleB child undefined const ruleC array find c gt c child child return ruleA amp amp ruleB amp amp ruleC const hasAllChildren array subArray gt const ruleA array undefined const ruleB subArray undefined const ruleC subArray filter c gt hasChild array c length array length return ruleA amp amp ruleB amp amp ruleC Now What this function hasAllChildren array subArray does when called is checking if all items match to be available in the array Notice This method does not check if these passed arrays are equal It simply checks if the elements are available First it checks all the arguments passed to our method are defined array original array subArray comparing array For each element we need to check if element is available in the array We need hasChild array child to do this It finds the element in the array and returns true if found For all subArray elements it needs to return true The reason to check if undefined is that if not it returns true If all elements contains we can say that count of all checked available items is equal to the original array s size Finally we return if all rules and checks passed by returning ruleA ruleB ruleC Thank for reading	2022-03-19 05:16:44
