1、中国有哪些区块链技术开发公司？

区块链的特点是去中心化、去信任、集体维护、数据库可靠。这些特性足以让区块链成为新的技术发展点。很多企业已经开始研发区块链，其中很多是一些大型企业，主要表现在不同的企业对区块链的应用开发不同，主要是与企业有关。在提供交易系统和软件开发的同时，主要是盈堂中创，体现在很多开发方案上。

Block chains are characterized by decentralisation, detrust, collective maintenance, and reliable databases. These features are sufficient to make the block chain a new technology development point. Many enterprises have started to develop block chains, many of which are large enterprises, mainly in terms of their different applications of block chains, mainly business-related.

一是Bubbi Blockchain Company，该公司提供区块链底层技术服务和行业解决方案。即构建底层区块链，并在其上构建适配层，使企业能够快速构建商业应用。底层区块链自行开发。共识机制是pbft，tps是每秒交易量，银联的每秒交易量是1、比特币的每秒交易量是7、当然，底层架构的性能是不同的。不同，因为 Bubi 做的商业区块链更注重性能。目前，Bubi主要应用于数字资产、供应链金融、供应链溯源、公证等领域。

One is Bubbi Blockchain Company, which provides bottom-of-block technical services and industry solutions. That is, to build the bottom block chain and build the right fit layer on it so that businesses can quickly build commercial applications. The bottom block chain develops itself. The consensus mechanism is pbft, tps is a transaction volume per second, the silver union is 7 per second, of course, and the bottom structure has different performances. Unlike Bubi, the commercial block chain is more performance-oriented. Bubi is currently used mainly in the areas of digital assets, supply chain finance, supply chain traceability, and notarization.

第二、不萌区块链。理论上，布盟应该说是布比的产品线，但布比主要是私有链，布盟是联盟链，所以分开来看，布盟是布比在数字资产上的布局。底层技术是Bubbi区块链，但是根据场景对区块链进行一些封装，为企业提供API接口，企业可以在上面发行自己的资产，根据特性进行资产的自由流通的区块链。保险、千向金融、中拓邦、好货等公司接手，里面的资产包括保单、积分、理财产品等。最后，估计这个平台会突破资产之间的壁垒，最终用户可以自由使用和转移这些资产。这是区块链行业的一种有趣的玩法，因为它既有公链的开放性，也有私链的安全性。

The bottom technology is the Bubbi block chain, but some wrapping of the block chain, based on the scene, provides an API interface in which businesses can issue their own assets and freely circulate them according to their characteristics. Insurance, thousands of financial, middle-tone, good goods, etc. companies take over the assets, including insurance policies, points, property items, etc. Finally, it is expected that the platform will break through the barriers between assets, allowing end-users to freely use and transfer these assets. This is an interesting game for the sector chain industry, since it is open to public chains and secure to private chains.

第三、唯链，唯链是基于区块链技术的商品ID管理云平台，以BaaS的形式为企业级用户提供商品资产管理、溯源、防伪验证、新型供应链管理。简单的理解就是唯链做了Bubbie区块链的“供应链溯源”的内容。

Third, the chain-only commodity ID management cloud platform, based on block-chain technology, provides business-level users with commodity asset management, traceability, forgery-proofing, and new supply chain management. The simple understanding is that the chain is the “supply chain trace” of the Bubbie block chain.

第四、同心互助，同心互助是一个互助保障平台，将一些互保相关信息放入区块链，用户可以申请成为节点，参与记账，维护自己的数据。

Fourth, solidarity, which is a mutually supportive platform, places information on mutual security in the block chain and allows users to apply to become nodes, participate in bookkeeping and maintain their own data.

5、小易，小易是一种基于区块链技术的去中心化网络协议，将现实世界的资产和权利数字化，通过点对点网络进行注册、发行、转账交易、清算和交付。

A simple, easy-to-be, decentralized network agreement based on block chain technology, digitizes the assets and rights of the real world, registering, issuing, transferring transactions, liquidating and delivering through a point-to-point network.

这五家区块链公司在国内比较有名气，我个人推荐不萌。

These five block chains are more well known in the country, and I personally recommend them.

首先，布盟采用布比区块链底层技术，业内相对看好，在国内落地应用最多。企业可以访问，不仅可以低成本使用（只要调用接口，好像是免费的）。有了区块链技术，你仍然可以使用里面的资源。考虑与许多公司处于同一链条上。未来，资源的连接不容易让用户转化。

First, the Union uses the techniques of the bottom of the Bubi block chain, which are relatively good in the industry and most applied in the country. Enterprises can access them, not only at low cost (as long as they call the interface, as if they were free). With block chain technology, you can still use the resources in it. Consider being in the same chain with many companies. In the future, the connection of resources will not be easy for users to convert.

第二、唯链和同心互助专注于某个领域，不提供底层技术和行业解决方案。也就是说，如果你属于这个行业，或者你可以上下游使用，你就不能用在其他领域。现在，以互助和安全领域为例，中拓帮和斑马俱乐部都选择了布盟。当然，如果是投资，可以考虑。

Second, chain-only and peer-to-peer focus on one area, without providing bottom-up technology and industry solutions. That is, if you belong to this industry, or you can go up and down, you can't use it in other areas. Now, for example, in the area of mutual assistance and security, both the Midto Gang and the zebra Club have opted for the Alliance. Of course, if it is an investment, it can be considered.

第三、小易，为什么不推荐小易呢，因为小易是开源项目，国内的商业环境大家都懂，尤其是行业刚刚起步的时候，国内市场和国外市场是不一样的国家，而且小易已经经历了两轮ICO，以后的运营会是一个很大的后顾之忧，而且目前小易还没有投入实际应用，暂时没有被公司使用做了一个发大的平台（估计跟开源的因素有关，谁敢在企业里用？我自己的数据是完全开放的），当然小易的开放态度还是值得鼓励的，虽然我猜代码的优缺点，同行都很好理解，但也不是比较清楚。

Third, it is small, why it is not small, because it is open-source projects, and the business environment in the country is well understood, especially when the industry started, the domestic and foreign markets are different countries, and the small has already gone through two rounds of ICO, and the future operation will be a great concern, and it is not yet operational and has not been used by the company for the time being to make a big platform (estimates are related to open-source factors, who dares to use it in the enterprise? My own data are completely open), and certainly the easy openness is encouraging, although I guess the code's strengths and weaknesses are well understood by my peers, but it is not quite clear.

第四、为什么不推荐布比？布比前段时间投资了1万元，因为布盟更开放，资源也更多。当然，如果业务对隐私性要求高，也可以选择 Bubi 区块链。

Fourthly, why not recommend Bubi? Bubi invested $10,000 in the previous period, because the Alliance is more open and has more resources. Of course, if the business demands more privacy, it can choose the Bubi block chain.

最后，为了我的努力和这么多的答案，选择我！

Finally, for my efforts and so many answers, choose me!
