[Extended information]
Blockchains are divided into three categories. Hybrid blockchains and private blockchains can be considered as broad private chains. Public blockchains refer to any individual or group in the world. Send a transaction, and the transaction can obtain valid confirmation from the blockchain, and anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major Bitcoin series are based on the public blockchain. There is only one block corresponding to this currency in the world. chain.
Industry Blockchain: Multiple pre-selected nodes are designated within a certain group as bookkeepers. The generation of each block is jointly decided by all pre-selected nodes (the pre-selected nodes participate in the consensus process), and other access nodes can participate. transactions, but does not involve the accounting process (it is essentially still managed accounting, but becomes distributed accounting. How many pre-selected nodes and how to decide the accountant of each block becomes the main risk point of the blockchain), others Anyone can conduct limited queries through the blockchain’s open API. Private blockchain: only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, with exclusive write permission to the blockchain. This chain is not much different from other distributed storage solutions. the difference.

3. StarBit’s ipfs Hummingbird H1 mining machine has its own unique advantages
Most of the mining machines currently on the market have limited storage and do not support expanded storage, which is fatal for a good mining machine. Yes, without large storage space, there is no way to ensure the income of miners. Interstellar Bit's Hummingbird H1 can expand the storage to 20TB, which greatly increases the storage space of the mining machine, and the income is naturally much higher than other mining machines. Regarding the life of the mining machine: in terms of the operating system, the Interstellar Bit ipfs mining machine Hummingbird H1 can be said to be far behind other mining machines of the same type. Currently, most mining machines use pirated windows systems, but pirated windows There is a very high risk for the initial investment of pledged coins, and 24-hour startup will cause great damage to the hardware, which is tantamount to slowly damaging your income. Hummingbird H1 is equipped with the IPFS OS operating system (based on Linux), which has monitoring and analysis functions. It can check the status of the mining machine 24 hours a day, which is a function that no similar mining machine has.
3. Interstellar Bit is one of them
To put it bluntly, it uses idle home broadband for blockchain technology to help with calculations and provide edge traffic for various video, live broadcast, games and other businesses. I used DIY Synology to install Starbit a long time ago, because the performance is too much, and running a virtual machine is more than enough. Now I use QNAP TS-451D, which is a J4025 CPU. Although it only has dual cores, the main frequency is still Yes, the performance is usually not satisfactory. If you want to install a virtual machine, it should be no problem, and there is no QNAP installation guide online.

㈨ What are the relatively mature companies that develop blockchain technology?

Shandong Bianke Information Technology Co., Ltd. is a software development company with excellent technology.
[Blockchain Exchange]
Blockchain technology application research and development, exchange wallet system app development Blockchain technology is actually a new type of Internet. Why is it said to be a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of pricePassed by value. Source Zhongrui Blockchain System Development Blockchain has many value transfers, such as distributed ledgers, decentralized trust, smart contracts, etc. So what kind of society will it build in the future?
The answer is: a distributed business and self-disciplined society. The first characteristic of blockchain is decentralization; no third-party intervention is required to realize person-to-person, point-to-point transactions and interactions.
Second, the information cannot be tampered with; once the data information is written into the block, it cannot be changed or revoked.
Third, openness and transparency; within a very short period of time, the block information will be copied to all blocks in the network to achieve data synchronization across the entire network, and each node can trace back all past transaction information of both parties.
Fourth, collective maintenance; in the entire blockchain network, all roles jointly maintain the reliability and security of the entire blockchain information.
Fifth, reliable database; only by mastering 51% of the nodes in the entire system can the blockchain information be tampered with. This is obviously impossible because there are many participants in the entire system and it is extremely costly to master so many nodes. It can't be achieved either.
The characteristics of blockchain bring great opportunities to the financial industry. Using it to transform internal application scenarios in the industry can bring three main benefits:
1) Reduce costs: communication Cost: Centralized trading markets generally require the participation and coordination of multiple parties such as central settlement systems, securities companies, exchanges, and banks. The coordination cost is very high. Through blockchain signature encryption and other technologies, information can be shared and coordination costs can be reduced; Operating costs: Reducing manual labor and paper vouchers, increasing automation through smart contracts, and centralized coordination also bring very high operating costs.
2) Improve efficiency: The settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, it is actually a settlement process that combines clearing, settlement and auditing. The openness, transparency and non-tamperability of the blockchain can save traces of operations, allow supervision records and audit traces to be retained, and facilitate supervision and auditing.
3) Risk reduction: Transaction confirmation on the chain completes clearing and calculation, greatly reducing transaction risks Blockchain technology application research and development, exchange wallet system app development
