Alliance chain doesn't care about computing power

1.
blockchain is strictly divided into three types: public chain, private chain and alliance chain. The core difference between these three types of blockchains is the degree of openness or decentralization of access rights. Generally speaking, the higher the degree of decentralization, trust and security, the lower the transaction efficiency
generally speaking, each type of blockchain has its own specific mode and value, which is better than others. As long as the demand is solved, the blockchain is valuable
2. The degree of decentralization of public chain. This kind of public blockchain, represented by bitcoin and Ethereum, is not controlled by a third party. All people in the world can read the data records on the chain, participate in transactions and compete for the bookkeeping rights of new blocks
program developers have no right to interfere with users, and each participant (i.e. node) can freely join and exit the network, and carry out relevant operations according to their wishes
private blockchain is on the contrary. The write permission of the network is fully controlled by an organization or institution, and the data read permission is regulated by the organization, either open to the outside world or with a certain degree of access restrictions
in short, it can be understood as a weakly centralized or multi centralized system. Because the participating nodes are strictly limited and few; Compared with public chain, private chain has shorter time to reach consensus, faster transaction speed, higher efficiency and lower cost
the alliance chain is a blockchain between the public chain and the private chain, which can realize "partial decentralization"
each node in the chain usually has its corresponding entity or organization; Participants join the network through authorization and form a stakeholder alliance to jointly maintain the operation of the blockchain.

4. 1. Alliance chain
the openness and decentralization of alliance chain are limited. Its participants are screened out in advance or specified directly. The read permission of the database may be public, or it may be limited to the participants of the system just like the write permission. Currency exchange of digital currency
2. Public chain
public chain is that every node in the blockchain is open, everyone can participate in the calculation of blockchain, and everyone can download complete blockchain data, also known as blockchain ledger
public chain refers to the process that anyone in the world can read and send transactions, and transactions can be effectively confirmed on the blockchain, and anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state
3. Private chain
202. What is private chain
private chain refers to the blockchain whose write permission is only in the hands of one organization. Read access is either open to the public or restricted to any extent. Related applications include database management, auditing, and even a company. Although in some cases, we hope it can have public auditability, in many cases, public readability is not necessary. It can be said that each of the three chains has its own advantages.

5. To put it bluntly, open source is sharing. In communities like Baptist publication, you can publish your research results on blockchain. Because a person's development and Research on technology is limited, after sharing, you can let everyone continue to research on your achievements or bottlenecks.
6. Alliance chain is a kind of blockchain. In a narrow sense, blockchain is a kind of distributed database. DBI alliance chain means that companies form an alliance to store their business card data (i.e. employee identity) in the form of blockchain. After checking, it is designed and initiated by micro technology, In theory, companies willing to join can become a node in the alliance chain
then why? Every company needs to use business cards to manage the identity of employees (some use the personnel management system). Once data is involved, enterprises have to worry about security issues (just as indivials can use pirated software, companies generally don't)
the advantage of forming an alliance chain is that it can ensure data security. If you use wild e-business card tools throughout the company, then all employees' identities are on other people's servers, and the probability of hacker attacks or data resale cannot be completely avoided
blockchain is decentralized, which is much better than the traditional server mode in terms of security and privacy. This is at the cost of sacrificing efficiency (low concurrency per second). However, according to micro technology, the research and development company of this chain, TPS can reach 20K, which is also very strong.

7. Public chain refers to the blockchain that anyone in the world can read and send transactions, and transactions can be effectively confirmed, and can also participate in the consensus process
alliance chain is only for members of a specific group and a limited third party, in which multiple preselected nodes are designated as bookkeepers, and the generation of each block is jointly determined by all preselected nodes
private chain refers to open to indivial indivials or entities
I hope it will help you and I hope it will be adopted.

there are basically so many, and the other mining probability is not big, because of performance problems, the efficiency of low-end graphics card is too low.

9. DERO has changed the original shortcomings of blockchain technology and reced the operational risk of participants e to too open data, which is really very important to our investors. At present, it has been in the coin dragon online line, and can pass the heavy screening of coin dragon. This shows that DERO is still of high quality.
10. DERO is a relatively new currency. It was issued in April this year and is now on the coin dragon website. On the basis of the original blockchain, DERO optimizes the intelligent contract, improves the privacy and security, and Deloitte will certainly release a very large value-added space.
