文/Colin2019 年区块链技术引发金融行业巨变的一年，是主流社会开始全面重视数字货币及虚拟资产的元年。须知，区块链无疑是互联网后时代最具颠覆性的技术之一，导致区块链颠覆性的根本原因在于技术本身，尽管目前人们对于区块链的认识尚且停留在非常表面和浅显的阶段。
很多人提到区块链，只会联想到数字货币和交易，认为区块链就是数字货币，区块链就是比特币就是中本聪…
其实数字货币只是区块链中技术的一种，举例：就像邮箱只是互联网的工具之一；QQ 只是互联网社交的软件之一…
曾经，比特币的”点对点电子现金系统”是货币自由的一个分水岭。有史以来第一次，人们可以安全地交换价值，而不需要第三方或信任的中间人。比特币通过使用分布式记录实现了这一历史壮举。
随着比特币价值的持续增长，大批公司开始筹建矿场。这些公司开发了专门的芯片(“ASIC”)，并利用这些 ASIC 芯片构建了巨大的服务器群来开采比特币。这些庞大的矿业公司的出现，推动了比特币淘金热，使得普通人很难为网络做出贡献并获得回报。他们的努力也开始消耗越来越大量的计算能源，导致全球环境问题日益严重。
这就是十年前的比特币只是区块链应用技术的最为初级、最为原始的样本导致，目前很多数字货币都是盲目的将数字货币甚至区块链技术局限在中本聪的世界里。而大部分人却知道互联网是日新月异的，不知数字货币的算力、传输技术、加密方式技术也在发生颠覆性的改变。
十年后的 Pi 却能够支持让普通人挖掘(或者通过验证分布式交易记录的交易获得加密货币奖励)。Pi 使用其他类型的一致性算法，并基于 StellarConsensusProtocol(SCP)和一个名为 FederatedByzantineAgreement(FBA)的算法。这种算法没有能源浪费，但是它们需要交换许多网络消息，以便节点对下一个块应该是什么达成”共识”。每个节点可以独立地确定一个事务是否有效，例如根据加密签名和事务历史确定进行转换和重复开销的权限。
早期我们只能通过笨重的纯屏台式电脑 ADSL 拨号上网，而现在可以可以通过光纤、4G、5G 等手段让笔记本、手机上网一样，不断技术革新，对比之下，区块链应用技术的优劣高下可见。
实际上，真正明白区块链的精髓和本质的人并不会把比特币或者 Pi 币的价格当成是发展的重点，他们会从技术入手来看待和发展区块链。在当前这样的一种市场状态下，这些人其实依然是有的，只是这些人的数量并不多而已，但是，正是这些为数不多的人可能真正掌握着区块链的未来。
相信未来基于区块链技术会出现更多的应用技术生态圈，可以实现技术上的自由流动、可以互补、可以自我更新。就像PI 币一样，未来一定会衍生很多的落地应用，我认为的 Pi 币未来应该就像加入美团等应用的线上线下实体商户一样，每一个实体和虚拟体都是支持PI 币的。
Pi 的出现，是我们面临整个金融体系革命的早期，诸位 Pi 友挖矿就像每天要吃饭一样，只是基础任务，还有很多有意义的事情要去做，去实现，历史的车轮滚滚向前,时代潮流浩浩荡荡…

In 2019, blockchain technology triggered a great change in the financial industry, which is the first year that the mainstream society began to pay full attention to digital currency and virtual assets. It should be noted that blockchain is undoubtedly one of the most subversive technologies in the Post Internet era. The fundamental reason for the subversion of blockchain lies in the technology itself, although people's understanding of blockchain is still at a very superficial and superficial stage.
Many people refer to blockchain, only think of digital currency and transaction, think blockchain is digital currency, blockchain is bitcoin is Nakamoto
In fact, digital currency is just one of the technologies in blockchain, for example: like email is only one of the Internet tools; QQ is only one of the Internet Social Software
Once upon a time, bitcoin's "point-to-point e-cash system" was a watershed of currency freedom. For the first time in history, people can safely exchange value without a third party or trusted intermediary. Bitcoin has achieved this feat by using distributed records.
As the value of bitcoin continues to grow, a large number of companies are preparing to build mines. These companies have developed specialized chips ("ASICs") and built huge server clusters to exploit bitcoin. The emergence of these huge mining companies has promoted the bitcoin gold rush, making it difficult for ordinary people to contribute to the network and obtain returns. Their efforts are also beginning to consume more and more computing energy, leading to increasingly serious global environmental problems.
This is because bitcoin ten years ago was just the most elementary and original sample of blockchain application technology. At present, many digital currencies blindly limit digital currency and even blockchain technology to Nakamoto's world. But most people know that the Internet is changing with each passing day. They don't know that the computing power, transmission technology and encryption technology of digital currency are all changing dramatically.
Ten years later, PI is able to allow ordinary people to mine (or obtain cryptocurrency rewards by verifying transactions of distributed transactions). PI uses other types of consistency algorithms and is based on stellarconsonsonsusprotocol (SCP) and an algorithm called federatedbyzantineagreement (FBA). This algorithm does not waste energy, but they need to exchange many network messages so that nodes can reach a consensus on what the next block should be. Each node can independently determine whether a transaction is valid, for example, according to the encryption signature and transaction history to determine the permissions for transformation and repeat costs.
In the early days, we could only dial up the Internet through the bulky pure screen desktop computer ADSL, but now we can use optical fiber, 4G, 5g and other means to let the notebook and mobile phone surf the Internet, and keep on technological innovation. By contrast, the advantages and disadvantages of blockchain application technology are obvious.
In fact, people who really understand the essence and essence of blockchain will not regard the price of bitcoin or PI as the key point of development, they will start from technology to view and develop blockchain. In the current market state, these people are still there, but the number of these people is not large. However, it is these few people who may really grasp the future of blockchain.
It is believed that there will be more application technology ecosphere based on blockchain technology in the future, which can realize free flow of technology, complement each other and self renew. Just like pi coin, there will be many landing applications in the future. In my opinion, PI coin should be like the online and offline entity merchants who join the application such as meituan. Every entity and virtual entity supports PI coin.
The emergence of PI is that we are faced with the early stage of the revolution of the whole financial system. Mining by PI friends is just like eating every day. It's just a basic task. There are many meaningful things to do and realize. The wheels of history roll forward, and the trend of the times is vast
