❶ 为什么比特币在中国命运多舛

自中国大陆宣布将于10月底关闭比特币交易以来，比特币的价格经历了一轮“过山车”行情。9月一度跌至25000元左右，10月又冲高至接近40000元，似乎显示出了顽强的生命力?
不过，这种高价却是很脆弱的。
中国大陆关闭场内交易之后，大陆比特币玩家大量转移至香港，由于部分交易所可以做期货，大约有10-20倍的杠杆。再结合场外交易即使在“爆发”之后，交易额也仅有前期场内交易量的1/100，可以看出，参与比特币交易的玩家数量已经大大减少，而少数炒家在借助杠杆的放大作用，勉强维持住了比特币的价格。
不过很难想象这些炒家完全是用自由资金在支撑的。考虑到资金的借用成本，和全球已经进入货币紧缩周期的事实，再加上越来越多国家对炒作数字资产风险重视度的上升，监管政策也会越来越密集，这种缺乏基础的高价恐怕难以持续太长时间。难道是少数早期囤币者为了寻找接盘侠而故意作的局?不是没有可能。
另一方面，官方发行的数字货币也在紧锣密鼓地筹备当中。实际上，从2016年下半年起，中国对官方法定数字货币的讨论就越来越多。2017年9月中国印钞造币总公司还设立区块链研究院，跟踪研究数字货币技术，这被外界普遍视为中国政府正加速研究推出数字货币的前兆。中国有可能成为首个发行官方法定数字货币的国家。
当然，这个过程不会是一蹴而就的，而且最终成品也会和比特币之类的数字资产有较大差异，更像是一种基于密码学的数字法币。现在的悬念是这种新的法定数字货币，其结算方式是类似于现在的网上银行模式的实时集中清算，还是可以离线的点对点结算。如果是后者的话，应用前景还会更广阔一些，使用可能也会更方面。
货币归根结底是交易的媒介和储藏财富的手段，本质是信用的体现。所以要在一个长时段里发挥货币的作用，这种媒介必须具备相当的信用。而现阶段和可预见的未来，最强的信用仍然来自政府的强力手段。假如现在有人拿出民国时期的金圆券，那只能叫古董。
所以从长期来看，我个人并不看好私人发行的货币。尤其是比特币在底层设计中就存在难以持久的逻辑缺陷，所以现在我们才看到不断有“扩容”现象的出现，而每一次这种“修正”，都是对其信用的伤害。
不过，即使比特币等私人数字货币成不了主流，但区块链技术却大有可为。比如数字产权认证。我们可以想象一下，在租房市场，如果法律强制房东或中介，在出租房屋前必须出示房屋的拥有官方或第三方认证的、基于区块链技术的所有权证明，那么假房源的问题想必会少很多。
在此基础之上，还能使远程在线抵押、交易成为可能。资产的数字化将使交易更便捷，可以进行更深多领域的应用探索，甚至能进行国际间的直接交易，如大宗商品、期货，贵重品(房产、珠宝、古玩、艺术平等)的远距离抵押、交易等等。
当然，这一切也需要配套的法律。只有出现了明确的判例，才能对未来建立在区块链基础上的产权保护起作用，才能树立公众对此的信心。“从零到一”会很慢，但一旦突破了临界值，有了第一个吃螃蟹的人，之后的“从一到一万”会飞快完成。
此外，国家之间的合作对应用范围的拓展也不可或缺。数字技术先天具有易于跨地域、跨国际传播的特点。当新的技术积累拼凑齐了所需的拼图之时，实现从量到质的突破就只差最后一层窗户纸了。突破是必然的，偶然性只是在于由谁来完成，大家都在拼命狂奔，但历史只会记住第一个冲过终点线的。
区块链作为新生事物，其应用范围和深度还有待探索，就像电力在诞生之初，人们也不知道它有什么用处。不过，随着人类行为与互联网及数字技术的融合越来越深入，类似区块链的密码学技术的前景一定是不可限量的。

❷ 区块链交易所全球排名里有ourbit交易平台吗

是有的，在非小号上查排名在37位

❸ 比特币十日大跌多少

据悉，自比特币2021年4月14日涨至64354美元大关刷新历史新高后，很快价格便出现逐步回调。第一次大跌出现在4月18日，一度跌至54009美元；第二次大跌则在4月23日，比特币价格再次从55000美元跳水至47600美元。十日内，比特币价格已大跌26%，市值蒸发数千亿美元。

其他主流虚拟货币也出现下跌，截至4月25日18时，以太坊、瑞波币、莱特币等币种，价格均较前段时间的高位下跌逾10%-20%不等。

比特币近期大跌的原因

从暴跌原因来看，零壹智库区块链研究总监、数字资产研究院研究员蒋照生告诉北京商报记者，比特币近期大跌主要是受外部因素影响，首先，以美中韩为代表的主权国家正加强对加密货币产业的税收和监管力度，一定程度上引起投资者情绪恐慌。

其次，全球经济正在逐步回暖，传统资本市场的避险资金量减少，比特币市场的增量资金减少，且早前由机构投资者带动的上涨行情正在消退。

❹ 比特币价格暴涨将加剧芯片短缺，比特币目前价格多少

继2月底之后，3月11日比特币再次登上5.7万美元高点。据加密数字币行情网站CoinMarketCap，3月11日凌晨3时许，比特币价格冲至5.7万美元以上，最高至57200美元，创下近两周来的新高。

不过，随后比特币价格持续下滑。截至发稿时，最新价格在55296美元，24小时涨幅为3.13%，市场价值达1万亿美元。

此前，今年2月底比特币价格冲破5.7万美元，一度创下历史新高，甚至在个别交易平台的价格已跃至5.8万美元以上。不过，随后数日价格遭遇大跳水，价格一度跌至4.3万美元。

(4)比特币合约研究院扩展阅读

比特币近期上涨的原因：

“本轮比特币牛市是高通胀预期下的产物。前段时间10年期美国国债收益率快速上涨时，市场认为美联储货币政策会比预期更快的发生转变，预测美联储会提前减少购买债券，甚至加息的时间也可能提前。在此背景下，比特币发生了暴跌。”欧易OKEx研究院首席研究员对《证券日报》记者分析称。

“比特币近期的上涨，是因为市场走出了前段时间的阴霾，对中长期通胀预期上升。”上述研究员认为，主要基于以下因素：

一方面，美联储有关10年期美国国债收益率的表态，打消了市场对货币政策转变的顾虑，市场通胀预期得到修正；

另一方面，美国通过1.9万亿美元的经济救助计划，此经济刺激方案将拉动社会需求的增长、推高商品价格，在一段时间内会抬升全球通货膨胀预期。

❺ 年薪百万的区块链职位薪酬存在泡沫吗

这天中午，31岁的郭杨 (化名)刚开完上午的技术会议，接下来还有七八个小时的技术讨论等着他，难得有时间从工作中抽离出来和朋友吃个饭，一听对方说了句“区块链技术总监年薪150万”，手一抖，碗差点翻了。

张作义现在的目标，就是以相同的方法完成区块链技术在其他场景的改造，他称，随着团队做的越来越多，大家看到有三百多上线的品牌商，已经有将近八千多个商品，就像搭积木一样，正在一些品牌商合作的基础上再建立起他合作关系。

郭杨此刻也踌躇满志。晚间9点，他加完班和朋友在公司食堂一边用餐，一边讲述区块链项目的最新进展，经历了区块链行业的起伏，也听了一些或悲或喜的消息，反倒觉得区块链这项技术更有生命力，更值得去探索。想到此，觉得当下工作让自己的野心得到了释放，并期待着建立一份真正属于区块链技术的事业。

❼ 比特币再现“杀猪盘”，是什么原因导致的

币圈的世界，总充满着“刺激”和不确定。就在前几日，所有币圈人士还在为比特币新高欢呼雀跃，但不到两天比特币又遭遇闪崩。11月29日，北京商报记者注意到，近7日以来，比特币价格从11月22日的17815美元一路上涨，在11月25日冲至19500美元，创近三年新高。但好景不长，11月26日比特币再现雪崩式下跌，日内一度跌超14%。

❽ 高耗能的比特币挖矿正在退出内蒙古，区块链和比特币到底有什么联系

要聊聊这两者之间的联系我们就需要先了解一些这两者各自的概念。

说到这里，其实可以发现，比特币是区块链技术运用最好的产品。而本中聪创造比特币的原因也是因为美国货币的超发和货币政策干预。比特币就不用担心这些东西。这也是为什么说比特币是去中心的货币。

❾ 一直关注比特币，从事区块链行业创业，哪有对初创者帮服力度大的区块链产业园或者孵化器谢谢大神帮助！

感谢邀请，我正从事区块链行业，对你的问题应该是可以解答的。

现在我国已经成立或即将成立的区块链产业园区已达10多家，比较有名的有杭州区块链产业园，重庆渝中区块链创业产业园，山东青岛“链湾”，长沙“麓谷”区块链产业园，武汉“凯利链谷”,其他还有上海、雄安、成都、广州、贵阳等地都有区块链配套基础设施。

杭州区块链产业园

先说最有名的——中国杭州区块链产业园，还记得当时在启动仪式时，币圈大佬李笑来不但为区块链产业园站台，还宣布成立100亿的全球区块链创新基金——雄岸基金。杭州政府层面甚至提出了“打造区块链之城”的愿景。

当时多家媒体报道杭州区块链产业园启动仪式时称“10个区块链未来科技项目现场签约，入驻中国杭州区块链产业园的项目”。结果后来有相当长一段时间也没有企业真正入驻，有圈地套取政策补贴的嫌疑。

青岛链湾

再就是青岛链湾，这家产业园其实还是不错的，首先有政府的大力支持，2017年7月，青岛市北区区块链产业发展意见发布会上提出力争到2020年，要建立立足青岛、面向全国的区块链产业高地，链湾于2017年9月13日正式落户青岛北区，面积为4万余平方米

其次链湾还有国内顶尖高校的支持，2018年5月，青岛·链湾和清华大学互联网产业研究院等联合主办的2018年青岛链湾双清区块链应用论坛召开，有近20家“清华系“的区块链企业入驻链湾。所以链湾我觉得比起杭州区块链产业园那种声势大雨点小要好的多，美中不足的是，青岛这地方竞争力确实弱了一些。

长沙“麓谷”区块链产业园

这个产业园其实有一些尴尬，尴尬在哪呢？因为它正式公布的时间实在太晚了，2018年11月23日，长沙区块链产业园揭牌仪式暨长沙区块链孵化器启动仪式活动在长沙高新区举行。看到了吗，去年11月，那时候正是数字货币行情进入冰点之际。不管从事区块链行业的从业者愿不愿意承认，行情确实会造成很大的影响。所以长沙区块链产业园的发展只能说是生不逢时。

我为什么还把长沙的区块链产业园拿出来介绍呢？因为长沙政府对于区块链的支持是最大的。可以看到各地政府都有出台相关配套政策，但大多是一揽子经济和科技计划中的一环，而且大多数只提了目标，没有具体措施。长沙政府出台了一系列针对区块链的配套政策，并且具体到补贴金额，因此长沙的产业园还是可以期待一下未来发展空间的。

武汉“凯利链谷”区块链孵化器

这个位于武汉的区块链孵化器是我最看好的。首先从区位优势来看，武汉是八省通衢的中心地带，交通网络覆盖周边各省；另外湖北是科教大省，武汉市的教育资源仅次于北京上海等城市，人才和科技资源丰富，区块链的发展前景巨大。

其次凯利链谷自身的实力就很雄厚，到2020年底，将建成12万平米优质办公场地，基本覆盖1.5线城市，预计投入创投基金超过2个亿。依靠区块链技术，将建立区块链节点，为入驻企业提供区块链企业注册和股权登记、转让服务等，打造国内领先的基于区块链技术的联合办公和企业资源共享的众创新模式。

入驻凯利链谷的区块链企业将在孵化器中获取管理咨询服务，其中包括一般性商务代理服务和制定战略、管理制度、人力资源管理制度、市场分析和专业知识培训等。通过联合中国电子商会区块链专委会、亚洲SPT研究会、等区块链业内高端资源，孵化器内还建立了“区块链大学”人员培训机制，除了每两周举办一次的区块链讲座，还将举办各类公益性质的研讨、培训活动，汇聚区块链专家、创业极客和区块链爱好者，打造中国区块链产业发展的人才高地，弥补国内区块链人才匮乏的短板。

另外据我了解，凯利链谷已经有几个落地的区块链应用了，像比较有名的TD公链就是凯利链谷孵化，最近还在做全球超级节点竞选。

以上就是我认为国内的几个比较好的区块链产业园和孵化器，希望能对你有所帮助。

❿ 比特币中国是什么

9月14日消息，今日晚间，比特币中国在官方微信公众号发布公告，称比特币中国数字资产交易平台今日起停止新用户注册；2017年9月30日数字资产交易平台将停止所有交易业务。

❶ Why Bitcoin is ill-fated in China

Since mainland China announced that it would close Bitcoin trading at the end of October, the price of Bitcoin has experienced a "roller coaster" market. It fell to about 25,000 yuan in September, and then shot up to nearly 40,000 yuan in October. It seemed to show its tenacious vitality?
However, this high price is very fragile.
After mainland China closed down exchange trading, a large number of mainland Bitcoin players moved to Hong Kong. Since some exchanges can do futures, the leverage is about 10-20 times. Combined with the fact that even after the "outbreak", the transaction volume of OTC transactions was only 1/100 of the previous on-site transaction volume, it can be seen that the number of players participating in Bitcoin transactions has been greatly reduced, and a small number of speculators are using leverage to amplify effect, barely maintaining the price of Bitcoin.
However, it is difficult to imagine that these speculators are entirely supported by free funds. Considering the cost of borrowing funds, the fact that the world has entered a monetary tightening cycle, and more and more countries paying more attention to the risks of speculating on digital assets, regulatory policies will become more and more intensive. I am afraid that this kind of high price without a basis It's hard to last too long. Could it be that a few early coin hoarders deliberately set up a trap to find a successor? It’s not impossible.
On the other hand, preparations for the officially issued digital currency are also in full swing. In fact, since the second half of 2016, China has increasingly discussed its official legal digital currency. In September 2017, China Banknote Printing and Minting Corporation also established a blockchain research institute to track and study digital currency technology. This is widely regarded as a precursor to the Chinese government's accelerated research and launch of digital currency. China may become the first country to issue an official legal digital currency.
Of course, this process will not be accomplished overnight, and the final product will be quite different from digital assets such as Bitcoin, and will be more like a digital legal currency based on cryptography. The current suspense is whether the settlement method of this new legal digital currency is real-time centralized clearing similar to the current online banking model, or whether it can be offline point-to-point settlement. If it is the latter, the application prospects will be broader, and the use may be more comprehensive.
In the final analysis, currency is a medium of transaction and a means of storing wealth. Its essence is the embodiment of credit. Therefore, to play the role of currency over a long period of time, this medium must have considerable credibility. At this stage and in the foreseeable future, the strongest credit still comes from the government’s strong measures. If someone takes out a gold yuan coupon from the Republic of China now, it can only be called an antique.
So in the long run, I personally am not optimistic about privately issued currencies. In particular, Bitcoin has logical flaws in its underlying design that are difficult to sustain, so now we are seeing the phenomenon of “expansion” occurring, and every such “correction” damages its credibility.
However, even if private digital currencies such as Bitcoin cannot become mainstream, blockchain technology has great potential. For example, digital property rights certification. usYou can imagine that in the rental market, if the law forces landlords or intermediaries to produce official or third-party certified ownership certificates based on blockchain technology before renting out a house, then the problem of fake listings will be much less. .
On this basis, remote online mortgage and transactions can also be made possible. The digitization of assets will make transactions more convenient, enable deeper application exploration in multiple fields, and even enable direct international transactions, such as long-distance mortgages of commodities, futures, valuables (real estate, jewelry, antiques, art, etc.), Transactions and more.
Of course, all of this also requires supporting laws. Only with the emergence of clear precedents can future property rights protection based on blockchain be effective and public confidence in this be established. "From zero to one" will be very slow, but once the critical value is exceeded and there is the first person to eat crabs, the subsequent "from one to ten thousand" will be completed quickly.
In addition, cooperation between countries is also indispensable for expanding the scope of applications. Digital technology is inherently easy to spread across regions and countries. When the accumulation of new technologies has put together the required puzzle pieces, the only thing left to achieve a breakthrough from quantity to quality is the last layer of window paper. Breakthroughs are inevitable, the contingency just depends on who completes it. Everyone is running like crazy, but history will only remember the first one to cross the finish line.
As a new thing, blockchain’s application scope and depth have yet to be explored. Just like electricity at its birth, people didn’t know what its uses were. However, as human behavior becomes increasingly integrated with the Internet and digital technology, the prospects for cryptographic technologies like blockchain must be limitless.

❷ Is there ourbit trading platform in the global ranking of blockchain exchanges?

Yes, it is ranked 37th on Feixiao.

❸ How Much Did Bitcoin Fall in the Tenth Day

It is reported that since Bitcoin rose to a record high of $64,354 on April 14, 2021, the price soon began to gradually correct. The first big drop occurred on April 18, once falling to $54,009; the second big drop occurred on April 23, when the price of Bitcoin once again plunged from $55,000 to $47,600. Within ten days, the price of Bitcoin has plummeted 26%, and hundreds of billions of dollars have been wiped out of its market value.

Other mainstream virtual currencies have also fallen. As of 18:00 on April 25, the prices of Ethereum, Ripple, Litecoin and other currencies have fallen by more than 10%-20% from their previous highs. wait.

The reasons for Bitcoin’s recent plunge

Judging from the reasons for the plunge, Jiang Zhaosheng, director of blockchain research at Lingyi Think Tank and researcher at the Digital Asset Research Institute, told Beijing Business Daily reporter, Bitcoin's recent sharp decline is mainly affected by external factors. First of all, sovereign countries represented by the United States, China and South Korea are strengthening taxation and supervision of the cryptocurrency industry, which to a certain extent has caused investor panic.

Secondly, the global economy is gradually recovering, and traditionalThe amount of safe-haven funds in the capital market has decreased, incremental funds in the Bitcoin market have decreased, and the earlier rally led by institutional investors is fading.

❹ The skyrocketing price of Bitcoin will intensify the chip shortage. What is the current price of Bitcoin?

Following the end of February, Bitcoin once again reached a high of $57,000 on March 11. According to the encrypted digital currency market website CoinMarketCap, at about 3 a.m. on March 11, the price of Bitcoin rushed to more than 57,000 US dollars, reaching a maximum of 57,200 US dollars, setting a new high in the past two weeks.

However, the price of Bitcoin continued to decline subsequently. As of press time, the latest price was US$55,296, with a 24-hour increase of 3.13%, and a market value of US$1 trillion.

Previously, the price of Bitcoin exceeded US$57,000 at the end of February this year, once hitting a record high, and even jumped to over US$58,000 on individual trading platforms. However, the price plummeted in the following days, with the price once falling to $43,000.

(4) Extended reading by Bitcoin Contract Research Institute

Reasons for Bitcoin’s recent rise:

“This round of Bitcoin The bull market is the product of high inflation expectations. When the 10-year U.S. Treasury bond yield rose rapidly some time ago, the market believed that the Federal Reserve's monetary policy would change faster than expected, predicting that the Federal Reserve would reduce bond purchases in advance and even raise interest rates later. It may be ahead of schedule. Against this background, Bitcoin has plummeted." The chief researcher of OKEx Research Institute told a reporter from Securities Daily.

“Bitcoin’s recent rise is because the market has emerged from the haze some time ago and expectations for medium- and long-term inflation have increased.” The above-mentioned researcher believes that this is mainly based on the following factors:

On the one hand , the Federal Reserve's statement on the yield on the 10-year U.S. Treasury bond dispelled the market's concerns about changes in monetary policy, and market inflation expectations were revised;

On the other hand, the United States passed a $1.9 trillion economic rescue plan , this economic stimulus package will drive the growth of social demand, push up commodity prices, and will raise global inflation expectations for a period of time.

❺Is there a salary bubble for blockchain jobs with an annual salary of one million?

At noon that day, 31-year-old Guo Yang (pseudonym) had just finished the morning technical meeting. There were seven or eight hours of technical discussions waiting for him. It was rare for him to take time off from work to have a meal with his friends. When he heard the other person say, "The annual salary of a blockchain technical director is 1.5 million," his hand shook and his bowl almost stopped. flipped.

Zhang Zuoyi’s current goal is to use the same method to complete the transformation of blockchain technology in other scenarios. He said that as the team does more and more, everyone will see There are more than 300 online brands and nearly 8,000 products. Just like building blocks, cooperative relationships are being established based on cooperation with some brands.

Guo Yang is also very ambitious at the moment. At 9 p.m., he finished addingBan and his friends were dining in the company cafeteria while talking about the latest progress of the blockchain project. After experiencing the ups and downs of the blockchain industry and hearing some sad or happy news, they felt that the blockchain technology has more vitality. , more worth exploring. Thinking of this, I feel that my current job has released my ambition, and I look forward to building a career that truly belongs to blockchain technology.

❼ Bitcoin reappears as a "pig-killing plate", what causes it?

The world of the currency circle is always full of "excitement" and uncertainty . Just a few days ago, everyone in the currency circle was cheering for Bitcoin's new high, but within two days, Bitcoin suffered another flash crash. On November 29, a Beijing Business Daily reporter noticed that in the past seven days, the price of Bitcoin has risen from $17,815 on November 22 to $19,500 on November 25, a new high in the past three years. But the good times did not last long. On November 26, Bitcoin fell again like an avalanche, falling by more than 14% during the day.

❽ Energy-intensive Bitcoin mining is withdrawing from Inner Mongolia. What is the connection between blockchain and Bitcoin?

Let’s talk about the two To connect them, we need to first understand some of their respective concepts.

Speaking of this, we can actually find that Bitcoin is the best product using blockchain technology. The reason Satoshi created Bitcoin was also because of the over-issuance of U.S. currency and monetary policy intervention. You don’t have to worry about these things with Bitcoin. This is why Bitcoin is said to be a decentralized currency.

❾ I have been paying attention to Bitcoin and engaged in entrepreneurship in the blockchain industry. Is there any blockchain industrial park or incubator that provides great support to startups? Thank you for your help!

Thanks for the invitation. I am working in the blockchain industry and I should be able to answer your questions.

There are now more than 10 blockchain industrial parks that have been established or are about to be established in our country. The more famous ones include Hangzhou Blockchain Industrial Park, Chongqing Yuzhong Blockchain Entrepreneurship Industrial Park, and Shandong Qingdao “Chain Industrial Park”. Bay", Changsha "Lugu" Blockchain Industrial Park, Wuhan "Kelly Chain Valley", and other places such as Shanghai, Xiongan, Chengdu, Guangzhou, Guiyang and other places have blockchain supporting infrastructurefacility.

Hangzhou Blockchain Industrial Park

Let’s talk about the most famous one first - Hangzhou Blockchain Industrial Park in China. I still remember that at the launch ceremony, Li Xiaolai, the currency circle tycoon, not only The Blockchain Industrial Park platform also announced the establishment of a 10 billion global blockchain innovation fund - Xiong'an Fund. The Hangzhou government has even proposed the vision of “building a blockchain city”.

At that time, many media reported on the launch ceremony of the Hangzhou Blockchain Industrial Park that "10 blockchain future technology projects were signed on site and settled in the Hangzhou Blockchain Industrial Park in China." As a result, no companies actually settled in for a long time, and there was suspicion of encircling the land to obtain policy subsidies.

Qingdao Lianwan

Then there is Qingdao Lianwan. This industrial park is actually quite good. First of all, it has strong support from the government. In July 2017, Qingdao Shibei District Blockchain At the industrial development opinion conference, it was proposed to strive to establish a blockchain industry highland based in Qingdao and facing the whole country by 2020. Lianwan officially settled in Qingdao North District on September 13, 2017, covering an area of more than 40,000 square meters

Secondly, Lianwan also has the support of top domestic universities. In May 2018, the 2018 Qingdao Lianwan Shuangqing Blockchain Application Forum jointly sponsored by Qingdao Lianwan and Tsinghua University Internet Industry Research Institute was held. Nearly 20 "Tsinghua-based" blockchain companies have settled in Lianwan. Therefore, I think Lianwan is much better than the Hangzhou Blockchain Industrial Park, which has a lot of fanfare and a small amount of rain. The only drawback is that the competitiveness of Qingdao is indeed weaker.

Changsha "Lugu" Blockchain Industrial Park

This industrial park is actually a bit embarrassing. Where is the embarrassment? Because it was officially announced too late, on November 23, 2018, the unveiling ceremony of Changsha Blockchain Industrial Park and the launching ceremony of Changsha Blockchain Incubator were held in Changsha High-tech Zone. Did you see that in November last year, it was when the digital currency market entered a freezing point? Regardless of whether practitioners in the blockchain industry are willing to admit it, the market situation will indeed have a great impact. Therefore, the development of Changsha Blockchain Industrial Park can only be said to be untimely.

Why do I introduce Changsha’s Blockchain Industrial Park? Because the Changsha government has the greatest support for blockchain. It can be seen that local governments have introduced relevant supporting policies, but most of them are part of a package of economic and technological plans, and most of them only mention goals without specific measures. The Changsha government has introduced a series of supporting policies for blockchain, and the amount of subsidies is specific. Therefore, Changsha's industrial park can still look forward to future development space.

Wuhan “Kelly Chain Valley” Blockchain Incubator

This blockchain incubator in Wuhan is my favorite. First of all, from the perspective of location advantages, Wuhan is the center of the thoroughfares of eight provinces, and the transportation network covers the surrounding provinces; in addition, Hubei is a major province of science and education, and Wuhan’s educational resources are second only to cities such as Beijing and Shanghai. It is rich in talent and scientific and technological resources. The development prospects of the chain are huge.

Secondly, Kelly Chain Valley itself is very strong. By the end of 2020, 120,000 square meters of high-quality office space will be built, basically covering 1.5-tier cities, and it is expected to invest more than 200 million in venture capital funds. Relying on blockchain technology, blockchain nodes will be established to provide blockchain enterprise registration, equity registration, transfer services, etc. to the settled enterprises, creating a leading domestic innovation model of joint office and enterprise resource sharing based on blockchain technology. .

Blockchain companies settling in Kelly Chain Valley will receive management consulting services in the incubator, including general business agency services and formulation of strategies, management systems, human resources management systems, market analysis and professional knowledge training wait. By uniting with high-end resources in the blockchain industry such as the China Electronics Chamber of Commerce Blockchain Committee, Asia SPT Research Association, and other high-end resources in the blockchain industry, the incubator has also established a "Blockchain University" personnel training mechanism. In addition to the blockchain held every two weeks Lectures, various public welfare seminars and training activities will also be held to bring together blockchain experts, entrepreneurial geeks and blockchain enthusiasts to create a talent highland for the development of China's blockchain industry and make up for the lack of domestic blockchain talents. Short board.

As far as I know, Kelly Chain Valley already has several implemented blockchain applications. For example, the more famous TD public chain is incubated by Kelly Chain Valley, and it is currently running for global super node election.

The above are what I think are some of the better blockchain industrial parks and incubators in China. I hope they can be helpful to you.
