我特别喜欢在技术文章中画图，有两个原因：对作者而言，如果能用图表达思路，侧面说明是真的掌握了；对读者而言，图形也比一维的文字更容易理解、信息量更大，图形中可以增加联系、颜色、形状等多维度信息。
所以一方面要让自己真的掌握一个知识点，另一方面要锻炼自己的画图表达的能力，以画图来反向验证自己对知识的掌握。画图的一些心得，参考我以前写的文章：《技术配图的一些心得》。
至于我用的画图工具，现在如果是随手画的图，就用excalidraw；一些更为正式的图，就用Mac上的OmniGraffle，可以很方便得对齐、调整颜色、字号大小等等，大几百买断的单机单平台软件，但是超值。

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
