Larry Liu, founder of Genaro Network, has a master's degree in artificial intelligence in computer science from Northwestern University, and was a security engineer at Hewlett-Packard in Silicon Valley, responsible for compiler development. Later, he continued to start businesses and explorations in the field of Internet and blockchain, and was good at the research and development of blockchain applications in cross-border payment, precision marketing, and data storage.
Larry introduced that Genaro Network is the first highly efficient programmable public chain that combines peer-to-peer storage networks. He believes that in the era of big data, data storage and reading and writing are very important, but at present, blockchains can only transfer transactions and cannot store them. Data, "We are providing a one-stop solution platform, so that developers can develop blockchain applications just like developing Internet applications."

Ear Finance: Please briefly describe your experience?
Larry: Previously, I worked in Silicon Valley as a security engineer and was responsible for compiler development. This experience is very helpful for what I do now, because the virtual machine compiles some instructions. These instructions can be understood as the language of the programmer. Generally, system operation requires three levels, from bottom to top, the execution level is machine-assembly-high-level language. When programmers do development, they convert the requirements into languages that machines can understand.
Now we can use the blockchain as a programming system. Ethereum has no reference at all. What the Genaro public chain has to do is something that no one has done before, and it will require a lot of new development and exploration. However, the difficulty of development does not mean that it is difficult for users to get started. Whether the developer API (Application Programming Interface) and the protocol are good or not is the effort that the development team needs to make. But no matter how complex the technology is, it can be used by users in a simpler form.
Ear Finance: Please briefly describe what you are doing?
Larry: What we are doing is the first efficient and programmable public chain that combines a peer-to-peer storage network.
In the era of big data, applications will have a lot of data to store, and applications will also need to read and write databases to find content. But at present, this cannot be done in the blockchain world, only transfer transactions. We provide a one-stop solution platform, so that developers can develop blockchain applications just like developing Internet applications.
Ear Finance: The reason for doing this project?
Larry: At present, the programmable public chain (such as Ethereum) and storage space (such as IPFS) on the market are two separate parts. If Ethereum is likened to CPU, IPFS is likened to hard disk, the two are used separately and in parallel, and they cannot give full play to their value. Only when the two are assembled into a whole computer can they be of greater value. What we have to do is such a thing.
Ear Finance: Brief introduction to the development process of the project?
Larry: In 2015, we made some applications based on Bitcoin. After Ethereum came out, our team also made a lot of explorations on it, such as digital marketing. During this process, we found some problems with Ethereum, such as insufficient performance, lack of storage, etc., which made some DAPPs unable to land, so we continued to summarize and reflect.
At the beginning of 2016, we felt that it was unrealistic to implement the application we wanted based on Ethereum or other public chains, so we decided to start the development of the underlying technology. Based on the fact that the public chain cannot be combined with storage at present, we decided to build a brand-new system ourselves, and intend to use this to solve the problems of blockchain throughput and security.
At the end of 2016, we completed the technical framework and started the research and development of the project. In October 2017, we launched the closed beta version of Genaro Eden, and in December we launched the public beta version of Genaro Eden. At the end of March this year, we launched the commercial version again. The Genaro Network public chain is also planned to be launched by the end of this year.

Ear Finance: The reason for adopting the SPoR+PoS consensus?
Larry: The energy consumption of the PoW mechanism is too high, and all unnecessary calculations are performed, so there is a trend in the industry that the PoS mechanism is excessive. But PoS is fragile and vulnerable to attacks, two of the most famous attacks are: Nothing-at-Stake and Long-Range Attack.
We were thinking about how to introduce storage and how to enhance the security of the public chain, so we introduced the SPoR consensus mechanism in our storage. Because we have already carried out the SPoR step in the storage network, based on the block-producing nodes produced by the storage nodes, the security of PoS is ensured.
To elaborate, the SPoR mechanism is a type of PoR mechanism. The PoR mechanism is the proof of data retrievability, that is, when a user retrieves his own data with his private key, the node needs to prove that the data belongs to him. This proof is efficient computation, which is needed even in Internet computing, and has been widely used.
Ear Finance: Can you understand that SPoR is used to increase security and reduce power consumption for PoS?
Larry: Understandable.
Ear Finance: Why did you choose to be a Turing-complete public chain?
Larry: A Turing-complete public chain can support the development of more Dapps.
What we need to do is to set up a computer with a public chain and storage to provide developers with a one-stop solution.

Ear Finance: What is the progress of public chain development?
Larry: At present, the architecture of the public chain has been designed, and the development of consensus algorithms and virtual machines is in progress.
At present, our smart contracts are still based on Ethereum, whoever shares will get the Token, and whoever buys will pay the Token.
The mapping will be done after the Genaro Network main chain goes online. Refer to EOS for this.
Ear Finance: Will the project involve cross-chain?
Larry: Cross-chain is something worth studying. We are also developing it and have cooperated with some public chain projects.

Ear Finance: If the policy requires the storage of content to be filed, what will be done?
Larry: The characteristic of blockchain is an autonomous system, and no one can take away the private key, but in order to obtain services, there is a price to be paid, which is a compromise that must be made.
To promote our products in any country, we will make different changes according to different countries' policies. There is a constant running-in process between products and policies, not only for us, but for all products.
Ear Finance: Will there be a phenomenon that files uploaded in China cannot be accessed abroad?
Larry: It is possible, although our product is still in the early stage, it is very likely that different versions cannot communicate with each other.
Ear Finance: Is it the user's storage content or storage behavior that cannot be changed?
Larry：用户可以删除自己上传的信息，不可更改是用户的交易记录，即上传下载等产生的交易记录。存储是用户的个人行为，数据所有权是用户的。但记录是区块链的。
耳朵财经：如何确保内容存储于用户的空闲空间上不会丢失？
Larry：去中心化存储是一件比区块链还要困难的技术，各个用户在使用存储空间的同时也会成为分享的节点。
目前大家普遍采取的是“冗余存储”，即将一个数据分拆成若干部分并且做若干份备份。但是随着规模的扩大，节点可能会跟不上。
我们暂时也采取这个技术，保持至少三次存储的架构，并为对安全性要求很高的用户或企业提供自定义设置。

耳朵财经：运行过程中有遇到什么困难？
Larry：Genaro Eden目前在区块链行业里好评如潮，但是在圈外推广确实遇到了一定的的阻力。和互联网产品相比，有私钥的区别，需要让用户明白私钥丢了就没有任何可以找回的办法了，这和银行卡忘了密码去银行更改不一样，你丢了就是丢了。
我们需要教育市场，让普罗大众认识到，自己需要对自己的行为负责。这个市场教育的过程需要一定的时间。
耳朵财经：用户规模以及市场规模，竞品。
Larry：Genaro Eden 17年12月公测版到商业版上线的3个月时间，前后共有几十个大矿场与众多用户参与，形成了几十个PB的级别。初期区块链项目不会一下子有大量用户，这些空间已经足够了。
至于市场规模，我们是基于共享经济的模型下，所有人都可以加入，这也就约等于有着无限的存储空间。
Genaro Network作为结合存储网络的公链目前没有竞品，Sia，IPFS等是Genaro Eden的竞品，此外，目前我们与Storj是合作关系，他们从2014年就开始做了，17年开始与我们战略合作，一直进行联合开发，也在研究共享节点的方案。
耳朵财经：项目的经济模型？
Larry：我们是一个开源的项目，基于基金会，不谈盈利。我们想为世界提供没有中间商赚差价的开源方式和社区，比如你购买多少存储空间的使用权，就会给分享者支持相应的Token。

耳朵财经：公链落地后的打算？
Larry：公链落地前后我们还会推出企业版，一个能存储数据库的版本，提供给企业用户使用。这也可以成为赢利点之一。
此外，我们还会请一些优质团队进行公链应用孵化，但是应用开发是无止境的事情，目前我们团队会将精力更多的放在开发基础设施上，应用由社区开发者完成。
耳朵财经：公链落地后的处理速度？
Larry：安全性是项目基础，我们会在不破坏安全的情况下提升效率。我们的目标TPS是千级别的公链。我们认为虽然可扩展性是支持应用落地的方式，但是提升到万级别而牺牲去中心化和安全性，是不必要的，千级别TPS是足够市场使用的。
耳朵财经：上线的的应用能否发币？
Larry：以太坊的ICO作为成功应用场景，也带来了大家可以轻易发币的隐患，就很容易产生泡沫。在我们的主链设计上，目标是既能稳定基础，项目也可以自己发Token，这会涉及到应用和公链的规则，我们会继续研究怎么进行引导。
耳朵财经：会做成交易所吗？
Larry：短时间不做考虑。两个原因，一是近两三年要专注于主业，二是其他技术可以进行置换，不需要交易所。
耳朵财经：最近EOS很热，公链会采取类似的超级节点吗？
Larry：我们和EOS相似也是部分节点共识。我们是首先所有节点都是存储节点，再选出委员会，再选成出块节点。
不过，我们的节点不是竞选出来的，而是依据客观事实的表现，在线时长、存储容量等，来判断是否可信任。
节点不能过少，数量在100-200个节点之间。选出的节点也不是长期的事情，会进行高频次的选举。
