在公园陪我儿子玩的时候翻完了结城浩的这本《图解密码学技术》，很通俗易读的实用手册，虽然都很浅显，但是对基本概念有比较全面的介绍。每一个程序员都应该读一读，至少要对密码学有基础的了解，不要等犯下不可挽回的错误后才后悔。 #book
和分布式算法一样，对密码学要时刻保持敬畏，要小心翼翼地遵守最佳实践，采用成熟的 SDK，绝对不要自己造轮子。

You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy.
