1. A management apparatus comprising:
processing circuitry configured to
in response to receiving a first request from a first node, provide the first node with first information corresponding to the first request, the first request being a request to control quality of communication within a group constituted by the first node and a plurality of second nodes, the first node and each of the plurality of second nodes each having a blockchain, the communication being communication for appending additional data to the blockchain, and the first node and the plurality of second nodes being configured to execute the communication;
wherein a receiving node among the plurality of second nodes receives the first information during forwarding of the first information within the group, and the processing circuitry is configured to set quality of communication related to a control target node to quality better than or equal to a first quality in response to receiving the first information in addition to a second request from the receiving node, the second request being a request to control the quality of the communication related to the control target node, and the control target node being one of the plurality of second nodes,
wherein:
the processing circuitry is configured to, in response to the first request being accompanied by both a third request and a fourth request, set both quality of communication related to the first node and quality of communication related to a connection node connected to the first node to quality better than or equal to the first quality, the third request being a request to control the quality of the communication related to the first node, and the fourth request being a request to control the quality of the communication related to the connection node; and
the connection node is a node among the plurality of second nodes, the connection node being connected to the first node not via any of the plurality of second nodes.
