區塊鏈概念是來自2008年中本聰發表的論文，全新的去中心化區塊鏈就此誕生，底層區塊鏈技術瞬間成為學術界與商業界熱門的開發主題。區塊鏈的核心技術包含密碼學、共識機制、分散式系統、點對點網路通訊和其他知名技術，並提供一個安全可信的分散式架構以及分散式帳本，隨著區塊鏈的出現引起不少學者的關注，區塊鏈具有去中心化、永久性、匿名性以及可驗證性的特性，已應用於眾多產業上，區塊鏈運作的機制中作為主要的核心技術——共識機制，其能有效的維護分散式系統，不僅能提高區塊鏈的一致性，也能有效防止區塊資料被竄改，提高區塊的真實性與可靠性；然而，區塊鏈中採用的工作量證明共識機制需要耗費大量能源來維護分散式系統，平均每秒驗證交易量只有5-7筆交易。因此，為了提升驗證效率以及能源消耗問題，本研究提出一個結合多層感知器與投票制度的共識機制，將採用機器學習中的多層感知器選擇超級節點，透過超級節點之間的投票來達成一致性的共識。最終實驗結果證明，本研究中提出的共識機制平均每秒驗證交易量14-15筆交易、平均共識時間落在40.127秒遠高於工作量證明每秒驗證7筆交易以及10分鐘的達成共識時間，不僅如此也採用DPOS選舉機制取代工作量證明雜湊競賽減少能源消耗的問題。

The concept of blockchain is derived from a paper published by Satoshi Nakamoto in 2008. A new decentralized blockchain was born. The underlayer technology of blockchain became a popular development theme in academic and business fields. The kernel technology of blockchain includes cryptography, consensus mechanism, decentralized system, peer-to-peer network and other well-known technologies. And blockchain provides a secure and reliable decentralized architecture and decentralized ledger. Blockchain has the characteristics of decentralization, permanence, anonymity and verifiability, and has been applied to many industries. The consensus mechanism is the core of blockchain technology. It can effectively maintain the decentralized system. It can not only improve the consistency of the blockchain, the authenticity and reliability of the block, but also effectively prevent the block data from being tampered.
However, the proof of work consensus mechanism used in blockchain technology required a lot of electric energy to maintain the decentralized system. The average verification transaction volume of proof of work was only 5-7 transactions per second. Therefore, in order to enhance verification efficiency and solve energy consumption issues, this study proposes a consensus mechanism that combines multilayer perceptrons and voting systems. Multilayer perceptrons will be used to select super nodes, and the consistency consensus will be achieved through voting between super nodes. The final experimental results prove that the consensus mechanism proposed in this study verifies 14-15 transactions per second on average, and the average of block verification time falls at 40.127 seconds. Compare to the proof of work system, which can verify only 7 transactions per second and spend 10 minutes for block verification, the consensus mechanism proposed in this study is quicker and more efficient. Besides, the adoption of DPOS election mechanism replacing the proof of work competition can help reduce energy consumption.
