1. In 2017, he began to work in the blockchain instry for three years, which witnessed the instry from obscurity to sudden outbreak and then to calm. Let's make a conclusion first. If you are willing to spend money, I suggest you go to professional IT consulting and delivery companies like ThoughtWorks / starwalker. In my understanding, the market is roughly divided into
1. The underlying chain platform providers, such as ant / network, usually only provide chain and development tools, but the specific instry / scenario solutions and development delivery capabilities are limited, which is not their focus. They want to use blockchain to package and sell more cloud services
2. Blockchain solution companies usually provide blockchain solutions in their own familiar fields, but most of them are small and medium-sized teams or start-up teams. Most of them have little difference in blockchain technology capabilities and have a deep understanding of their respective fields
however, the biggest problem for such companies is that because the blockchain instry is still in its early stage and there is no mature business model or profit model, most of them need external investment to continue their life, which leads to the difficulty in guaranteeing their service ability or continuous performance ability, and frankly speaking, their business is unstable
on the other hand, because it is not a professional end-to-end delivery or professional outsourcing, it has no mature methods, team and project management to ensure the efficient and complete delivery of a blockchain solution. So for buyers, it is easy to get out of control in the process of project development, or it is difficult to get satisfactory delivery results in the end
another common problem is that most customers do not know what to do with blockchain and how to combine their business to do a valuable and meaningful blockchain project. Under this kind of cognition, I blindly find a company to directly develop on the scheme, and it's easy to regret or even give up halfway after doing it. I see too many such projects, I can't figure out the situation, and I don't know what I want to do. It's easy to set up a blockchain. This kind of company usually does not have the ability of pre-sale business consulting, business analysis and planning, in other words, the ability to help you understand the situation. In a word, if you know what you want, it may be OK to find them. If you don't know, it's better to find a professional consulting company honestly
3. IT consulting and delivery companies, which are usually specialized in serving large customers in various instries, have a set of consulting and end-to-end delivery methods and team support. Well, there are not many blockchain businesses in these companies, because they are not limited to the narrow business of blockchain, such as Accenture or some domestic companies. However, ThoughtWorks is slightly different. It has a blockchain division, pre-sales consulting / business analysis services, and delivery services. Then it has blockchain projects in its own major customers in various instries. Automobile, finance, retail, energy, agriculture and so on

2.
There is a SIA blockchain network disk, which has been distributed all over the world
the storage capacity is 2.9pb, but the storage provider has 312 nodes less
in addition, BIFI Pro is also building such a blockchain network disk
3. In one sentence, it is decentralization
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
the so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data< Advantages:
1) the algorithm is simple and easy to implement
2) there is no need to exchange additional information between nodes to reach a consensus
3) it takes a lot of cost to destroy the system< Disadvantages:
1) waste of energy
2) it is difficult to shorten the block confirmation time
3) the new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack
4) it is easy to generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it.

4. In fact, the network has made some layout in the aspect of blockchain technology. The network totem blockchain does the right of pictures, the super chain does the application development platform of the underlying technology, the network intelligent cloud does the baas solution of blockchain, and the Xiaoman financial blockchain solution. Generally speaking, all those involved are involved, only in depth, Maybe Rongze blockchain will go deeper. Rongze blockchain team is a blockchain enterprise supported by the government in Nanjing. It has done a long time of research and development on the underlying technology of blockchain in government affairs, precision finance, medical treatment and new retail, and won various national blockchain awards. The patent strength of blockchain is no less than that of Huawei blockchain and ant blockchain, At the business development level, there are also strategic cooperation between global enterprises such as Starbucks and KFC, as well as some business cooperation at the government level. In the field of blockchain, Rongze blockchain has been doing well, which is no worse than network blockchain.
5. Bitcoin was developed with blockchain technology, which is a technology.
