臺灣博碩士論文加值系統

隨著網際網路的快速發展和普及，線上運彩已成為博弈市場中快速成長的部分。然而，傳統的線上運彩投注平台有一些缺點且無法忽視。其中一個主要問題是公平性，因為博彩公司所設定賭局的賠率會略傾向於對他們有利。此外，博彩公司比玩家具有資料分析與賠率計算優勢，同時博彩公司往往比玩家擁有更多的（內部）信息，更不用說，很多時候博彩公司會限制甚至禁止勝率高的玩家下注。因此，缺乏安全性，透明度和隱私，高額的抽傭和低投資報酬率等種種原因，都促使我們嘗試替代方案甚至探索更好的線上運彩平台。
自比特幣誕生以來，區塊鏈技術在過去幾年中備受關注。它為各種行業帶來願景，包括醫療保健，電子投票，供應鏈管理，金融服務，在線學習等。區塊鏈技術可以解決網際網路中數據處理的安全性，隱私性，透明性和可靠性等不同類型的問題。在本篇論文中，我們設計並實現了基於區塊鏈技術的點對點分散式在線體育/電子競技投注平台，為玩家提供自設賠率相互對賭的機制，中間沒有博彩公司或莊家介入，並使用符合ERC20標準的以太坊代幣與智能合約執行交易。已完成的賭局將寫入區塊鏈，為該交易提供透明度和可追溯性。所使用的智能合約成為可驗證的信任系統，只有當雙方線上撮合完成且確認可用籌碼額度時，交易會自動執行且儲存於區塊鏈中。因此，玩家可確認在獲勝後將獲得報酬。
我們實踐了運用區塊鏈技術與智能合約於點對點分散式在線體育/電子競技投注博弈平台，此研究結果有助於線上投注平台營運模式的革新。將來，此平台亦可應用於任何需第三方資金託管的相關賽局與博奕。

With the rapid development and popularization of Internet, online sports betting has become a fast growing segment within online gambling market. However, some drawbacks of legacy online sports betting platforms are considerable and should not be ignored. One of the main issues is fairness since odds are massively in favor of the bookmaker, as they usually skew the odds slightly in their favor. In addition, the bookmakers have a mathematical advantage over the players and the bookmakers tend to have more (inside) information than the players, not to mention that, in most cases, bookmakers usually restrict or band regularly winning players. Hence, the lack of security, transparency, and privacy, extortionate fees and low returns, all of which are factors for us to explore alternatives and look for better online sports betting platforms.
Since from the birth of Bitcoin, blockchain technology has catch massive attention in the past few years. It holds immense promise for a variety of industries, including health care, e-voting, supply chain management, financial services, on-line learning and more. Blockchain technology can solve different kind of problems, such as security, privacy, transparency and reliability of data processing on the Internet. In this dissertation we design and implement a peer-to-peer decentralized online sports/esports betting platform based on blockchain technology, providing the mechanisms for two players to bet with each other, without bookmakers or business entity in the middle, using ERC20 compliant coins and secure smart contracts. Completed trades will be published on the blockchain which provides transparency and traceable. The smart contracts act as a verifiable trust engine. Only when a deal is done and founds are confirmed available on both sides, would the transaction be stored on the blockchain. Hence, the players will know they will be paid when they win.
We have explored how the blockchain technology integrating smart contract functionality can be used to realize a truly peer-to-peer decentralized online sports/esports betting platform and so will contribute to the paradigm shift of online gambling. In the future, this platform can be used for any activity where tokens/funds are escrowed prior to a result and then settled to the winner.
