  • 挖矿行业的概况

    截止 2019 年 7 月，比特币矿工年均创造了超过六十亿美金的收益（包括挖矿奖励和交易手续费）。

    在密码学货币领域，确保比特币及其它密码学货币网络安全的基础硬件和挖矿活动是一个经常被人忽视的市场。然而，挖矿与交易结合起来，是创造可观利润的核心市场之一。

    在这篇文章中，我将分享比特币及其它密码学货币挖矿领域的概况、支撑挖矿的基础硬件、行业的生态，并深入探究这个领域的收益和市场规模。

    As of July 2019, Bitcoin miners generate $6B+ in revenues (mining rewards + transaction fees) on an annualized basis.

    Mining and the underlying hardware that secures Bitcoin and other cryptocurrency projects is an often overlooked market within the cryptocurrency sector. However in conjunction with the exchange landscape, mining is one of the core markets which generates significant revenues.

    In this post I will share an overview of the Bitcoin & crypto mining space, the underlying hardware which powers mining, an ecosystem landscape, and dive into the revenue & market size of the space.

  • 闪电网络的动态调解费用

    在闪电网络中，一位用户可以从相互连接的支付通道中找到一条路径来向另一位用户付款。在这条选定的付款路径上，付款方和收款方之间的节点就是调解节点，可以赚取调解费。

    这类调解费的收费模式可以设计得五花八门，通常会受少许几个参数的影响。良好的调解费模式设计可以激励通道平衡（译者注：即保证各节点都有一定的可用余额，以提高路由成功的概率），从而促进代币网络的健康发展。因此，要想支付通道网络能够良好运行，定义一个恰当的调解费框架很重要。

    Raiden lets users pay anyone in the network by using a path of connected payment channels to mediate the payment. Mediating nodes, which are the nodes between the sender and the receiver on the selected payment path, can earn mediation fees.

    The fee model for these kind of mediation fees can be designed in various ways and is usually influenced by a few parameters. Good mediation fee design can incentivize channel balancing and therefore may contribute to the health of a token network. Hence, defining the right mediation fee framework is an important aspect of a well functioning payment channel network.
