Summary:To enable rewriting of data on a block chain.SOLUTION: A data managing device 1 includes a writing process unit 112, and a rewriting process unit 113. The writing process unit 112 writes first data in a first block chain. The rewriting process unit 113 points, in the first block chain, a position where the first data is located, and writes data that is the updated first data in a second block chain.SELECTED DRAWING: Figure 4 【課題】ブロックチェーンのデータを書き換え可能にする。【解決手段】データ管理装置１は、書き込み処理部１１２と書き換え処理部１１３とを備える。書き込み処理部１１２は、第１のデータを第１のブロックチェーンに書き込む。書き換え処理部１１３は、第１のブロックチェーンにおける第１のデータの存在位置をポイントして、第１のデータの更新後のデータを、第２のブロックチェーンに書き込む。【選択図】図４
