在這個數位化的時代，大量數位資訊被放到網路上，這之中不乏存在為了謀取自身利益進而惡意修改有價資訊之人，因此驗證資訊正確性的必要性日漸高漲。然而傳統的存證主要由可信第三方進行存證，存證者在驗證資料正確性時僅將資訊交付給可信第三方後便等待可信第三方之結果，這樣不透明化的驗證方式在現今這個時代並無法完全取信於人。此外，若可信第三方內部出現資料管理員與他人勾串或是存證資料庫遭駭等情形，驗證結果將無法再被信任。
此時，人們紛紛想將資訊存證於擁有不可竄改性且透明性高的區塊鏈中，然而受限於高額的手續費與區塊鏈每秒交易筆數過低等限制，大量數位資訊並無法被妥善存證於區塊鏈中，因此本篇論文將探討結合batch compression所產生密碼學證據存證於區塊鏈中與驗證資訊存在與不存在之效能分析。
