如何透過區塊鏈解決因資訊不對稱所帶來的成本，以確保資訊的品質？在內容生產的過程中，版權保護以及紀錄是一個很大的成本來源，成本來自於我們必須去判斷版權資訊的真實性與遭有心人士侵犯版權所付出的代價，因而導致必須付出額外的處理成本。因此需要一個有效的版權管理機制來解決問題。區塊鏈(Blockchain)技術透過去中心化的模式，而不用藉由中介機構，並且將相關交易資訊紀錄於區塊鏈上，並由於其不可竄改性，將可以有效處理版權追蹤與保護問題。本研究之雛型架構將建立於區塊鏈上，以解決因版權保護和追蹤所帶來的問題。 本研究於以太坊上實作區塊鏈雛型架構，透過智能合約將交易及版權之雜湊值及記錄保存於區塊鏈上，基於區塊鏈之可追蹤性，可確保交易及版權來源之真實性，並透過雜湊值及時間戳記確保其完整性。 本研究發覺在此數位版權區塊鏈的架構底下，擁有從根本改變傳統制度的可能性，不再局限於傳統紀錄的限制，並能進一步節省交易成本。;Trust has been a major portion of the cost in copyright management. The high cost we pay for trust comes from the need of information validity. How to solve the cost of information asymmetry through blockchain to ensure the quality of information? The process of content production, copyright protection and record processing are great sources of cost. Such a cost issue can be oriented from judging copyright authenticity and being intruded by malicious person. Therefore, we need an effective copyright management mechanism to solve the problem. Blockchain technology can support copyright tracking and protection through a decentralized model and encryption algorithm. Moreover, through Blockchain’s Incorruptible feature, we can effectively deal with copyright tracking and protection issues. This study’s prototype will be established on Blockchain to solve the problem of copyright protection and tracking. This study implements the blockchain prototype structure in Ethereum and saves the transaction and copyright hash values and records on blockchain through smart contracts. Based on the trace ability of the blockchain, it ensures the transaction and copyright sources’ authenticity and ensure their integrity through hash values and time stamps. Under the framework of this digital copyright blockchain in this study, we found possible way to change the traditional system. Finally, traditional record processing cost and transaction cost can be reduced dramatically.
