序

lutely every industry will become more decentralized，or even that those industries that will become more decentralized will do so through blockchain technology specifically.Every industry is its own special case，and it is，for example，hard to see how the construction ofabillion-dollar rocket going to Mars could be economically managed byadecentralized automaton or smart contract running on Ethereum.However，the possibilities are many，and 2016 is the year where the initial proof of concepts for real-world use cases are starting to be developed and tested.2017 will be the year where，just as is the case in any industry，over two thirds of them will inevitably fail，but the remaining third will be expanded further into real-world applications reaching millions of users-and that is when the next phase will begin.

（诚然，不是所有行业都会变得更为去中心化，而那些会变得更为去中心化的行业也需要通过更为个性化的区块链结构来实现去中心化。因为每一个行业都是自身的一个特例，也因此，举例来说，就是很难去预测如何通过在以太坊上运行的去中心自动化或者智能合约，来使得建造一个几十亿美元的火箭并把它发射到火星这件事变得经济实惠。然而可能性依旧很多，2016年，正是现实世界应用场景的概念性证明开发和测试开始的一年；2017年，在某些行业，将会有2/3的应用场景不可避免地失败，但剩下的1/3将会进一步扩张成为现实世界的实用性应用，并达到几百万的用户数量，而那也会是下一阶段的开始。）

I hope that you enjoy reading about the past，present and future of what blockchain technology has to offer，and that this book will inspire you to become part of that future yourself.

（我希望你会享受阅读这本关于区块链的过去、现在和未来的书，并且我相信这本书将会启发你，使你成为未来的一部分。）
