比特幣 - An Overview



我們會在這裡解釋比特幤挖礦如何運作、探討要有多少算力才能維持其區塊鏈運作,也會看看一些能夠善用挖礦硬體的工作量證明系統。

挖礦會消耗大量計算資源,能夠得到區塊驗證權的幸運兒,必須比網路上的其他人先解出一個數學難題。(這就是整個工作量證明的概念,利用大量的算力來避免遭到分散式服務阻斷攻擊)。

個人認為一套完整併且符合科學依據的交易系統主要包含以下三個核心方面:

The overwhelming majority of mining electricity is grouped together in mining pools to lower variance in miner cash flow. Unbiased miners could have to operate for a number of yrs to mine just one block of transactions and get payment.
