Abstract: Disclosed herein is a method for selecting a consensus node in an apparatus for generating a blockchain. The method may include reading a nonce from the nonce chain of a node, performing an operation on the read nonce and previous height information, and comparing the result of the operation with a reference value in order to select the node as a consensus node.

Abstract: Disclosed herein is a method for generating a blockchain, which includes selecting, by a first master node that generated a first block, second candidate nodes from a node pool according to a consensus node selection scheme using a nonce, and selecting, by the first master node, a second master node using the result of a vote taken by first candidate nodes. Here, among candidate blocks generated by the second candidate nodes, the candidate block generated by the second master node is locked as a second block.

Abstract: Disclosed herein are an apparatus and method for providing long-term function execution in a serverless environment. The method for providing long-term function execution in a serverless environment is performed by an apparatus for providing long-term function execution in a serverless environment, and includes registering a long-term function execution proxy when a long-term execution request is received from a client, allocating a long-term function executor corresponding to the long-term execution request, executing, by the long-term function execution proxy, a long-term function using the allocated long-term function executor, and storing execution results of the long-term function.
