The lucky chain node queue qpos algorithm is a brand new blockchain equity proof consensus agreement. It is a new node queuing mining consensus algorithm developed by the Lucky Chain team based on the Microcoin pos 3.0 protocol. This protocol has passed preliminary tests. We are applying for a patent for this original agreement. The qpos protocol changes the blockchain consensus algorithm from the past equity competition to the node ring queue.

The registered online nodes generate new blocks in turn according to the registration order, which fundamentally solves the pos protocol. Blockchain systems are prone to problems such as block reorganization and forking and 51% attacks. In the qpos protocol, we use the algorithm of register entry and queue sorting. In the software, the user can apply to join the node queue, and then determine the order of the nodes in the queue according to the registration order and the time of the latest block.

Each node has the opportunity to participate in mining. When a node discovers a new block, it will automatically be queued to the end of the queue, and then the next node will continue to sort for mining. When the player registers the node, it is necessary to set the term of the coin lock. The consensus algorithm generates different block rewards according to the length of the coin lock period. In order to prevent the malicious application of the node and improve the efficiency of the network consensus, the algorithm is limited to hold more than 1 million coins to be eligible to join the node queue.
