try to build something on it.However，the technology was still in its early phase，and discussion about practical applications was rare; many startups would literally include as part of their pitch deck to venture capital firms an assumption that the bitcoin price would increase byafactor of four every year，and in some cases that was the closest thing toabusiness model that these companies had to speak of.In 2014，that model suddenly，but inevitably，began to falter，as the price went in the exact opposite direction to the three years before，and so entrepreneurs looking to change the world with blockchain technology began to look toaradical new strategy to earn their revenue:finding actual use cases，and working with actual customers and traditional enterprise to try to bring those applications fromaconcept in their heads，to a proof-of-concept written in code，and finally toaproduct that would be used by millions of people.And it is not just startups that are getting involved;despite the anti-bank sentiment of many of the technology's earliest advocates，today it is the banks that are among the most prominent developers of blockchain applications.Blockchain technology is growing up，and is finally coming of age.

（于我而言，最让我印象深刻的是过去这五年来这项技术的发展速度，以及这个行业进化的速度。从2010年到2013年，关于区块链技术有许多令人激动和充满潜力的进步，许多初创公司正在逐渐形成并且尝试着在此技术之上建立一些新的东西。然而，这项技术仍然停留在它的早期阶段，关于实践应用的讨论仍然比较稀少。许多初创公司仅仅将“区块链”放入他们对风投公司的融资演讲稿中，并且假设比特币的币价每年都会上涨4倍，而在某些情况下币价与这些公司的商业模式密切相关。2014年，这些模式突然间（也不可避免）开始走得颤颤巍巍，因为比特币的价格完全向三年前相反的方向发展。于是那些致力于使用区块链技术改变世界的企业家们，开始寻找一种激进的新策略来赚取他们的收益：寻找真实的应用场景，并且与真实的客户以及传统企业合作，从而将他们的应用从脑袋里的概念转化为证明概念的代码，最终成为能够被成千上万人使用的产品。事实上，参与其中的也并不仅仅是初创公司，连最初区块链技术倡导者们认为反对该技术的银行，今天反而成了区块链应用开发的中坚力量。区块链技术正在成长，也终于成长到了一个新的时代。）

Personally，at my age of 22，I do not have decades of experience in any industry，except perhaps the twelve years whichIhave spent writing code，the first six of which largely consisted of writing computer games thatIwould later spend thousands of hours playing myself; hence，I am not the person who will b
