Mobile Internet blockchain Wallet

1. There are many kinds of wallets in the market, which can be divided into desktop wallets, mobile wallets, online wallets, hardware wallets and paper wallets according to the platform; According to whether it is connected to the network, it can be divided into cold wallet and hot wallet; According to the degree of autonomy and the way of interaction with the network, it can be divided into full node wallet, SPV light wallet and third-party wallet
for blockchain wallets, you can see the evaluation of wallets in password finance if you go to the tutorial.

If bitcoin represents blockchain version 1.0, it proves to the world that digital currency can be realized. Then Ethereum represents blockchain version 2.0, which lets you know more about the play of blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the stage of 3.0, application and scenario landing will be the core of blockchain, and blockchain based applications in various instries will spring up, which will be the early dividend period of the last stage of blockchain development. The demand for talents driven by the application of blockchain technology has become increasingly large. Blockchain technical talents have become the new professional talents, which are highly competitive, and also have enviable high salaries

whether to form a meaningful large-scale consensus: one of the outstanding advantages of blockchain is that it can effectively form a large-scale consensus by opening account books and notifying the whole network. At present, there is no need to form a network wide consensus for many projects. Some projects are just for crowdfunding and token issuance. The blockchain consensus of projects is meaningless. Does this model have network effect: network effect means that a project will become more and more valuable with more and more users of the project, because the value of the project is not in the users themselves, but in the connection network between users. Bitcoin is a typical example. The more user nodes there are, the more links between nodes will grow exponentially, and the whole ecosystem of bitcoin will be more valuable

of course, in addition to these points, there are many basic principles to judge the project, such as effective incentive mechanism, strong team, project solving pain points, and so on

3. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.

4. Blockchain wallet is a tool to save the private key of blockchain digital currency. Every digital currency has a wallet. The types of blockchain wallet are as follows:
1. General wallet
can support different blockchain tokens. For example, anmao wallet supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series
2. Main Chain Wallet
in order to achieve their own goals, each coin must establish its own main chain, so that it can carry out business. After the main chain goes online, it needs to use the project's own wallet. Just like the green apple wallet of GAC coin, it is a wallet dedicated to GAC trading and transaction clearing
3. Exchange wallet
there are also wallets in the exchange. If the player's currency is recharged into the exchange, the corresponding currency will enter the exchange wallet. The exchange wallet is almost the same as the ordinary wallet. You can fill in the corresponding wallet address when transferring and withdrawing cash, and the corresponding wallet address will be generated for different currencies of each exchange
4. Hardware wallet
generally speaking, the wallet is software wallet, which is a PC program or app. As the name suggests, a hardware controlled wallet can be connected to the network when it is used, and can be stored off the network at other times, so as to avoid exposing the wallet to the network space.

5. In order to understand the blockchain wallet, we must first understand several core concepts
1. Wallet address: similar to the bank card number, a person can have multiple bank cards. Similarly, he can also have multiple wallet addresses. A wallet address can only correspond to one private key
2. Wallet ID: customer ID (name) similar to bank card
3. Public key and private key: the holder of the private key is the holder of the currency in the bank card. The private key can calculate the public key, the public key can generate the wallet address through a series of digital signatures, and the data encrypted by the private key can be decrypted by the public key, or vice versa
I know this area quite well, and I have some ideas to develop a blockchain wallet. After all, it is a high-tech wallet. Before I learned about a development company called Xuanling technology on the Internet, and also consulted the people over there. I felt that it was quite professional. I hope I can help you~

6. The difference of wallets on the market is not obvious, mainly e to the classification:
centralized wallets: suitable for novices, easy to manage
decentralized
cold wallets (offline wallets)

7. I have been using tokenpocket for a long time. It has good security. It supports 11 kinds of bottom layers, such as bitcoin, Ethereum, EOS, Iost and coin security. Moreover, DAPP should be the most abundant in the wallet. I can solve many problems with this wallet
