Blockchain public chain app

❶ What are the public blockchain chains

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. The public chain is a peer-to-peer electronic cash system: Bitcoin, smart contracts and a decentralized application platform: Ethereum.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods associated with each other. The generated data blocks, each of which contains a batch of Bitcoin network transaction information, is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

(1) Extended reading of blockchain public chain app

According to the degree of centralization of the blockchain network, there are three different application scenarios of the blockchain:

1. The blockchain is open to the whole network and has no user authorization mechanism. It is called a public chain;

2. Authorized nodes are allowed to join the network, and information can be viewed according to their authority. It is often used in inter-organizational blockchains, called alliance chains or industry chains;

3. All nodes in the network are in the hands of one institution, which is called a private chain.

Consortium chains and private chains are also collectively referred to as permissioned chains, and public chains are referred to as permissionless chains.

Blockchain features

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. Except for the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and management. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition to the encrypted private information of transaction parties, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces. System information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm adopted by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

4. Security. As long as 51% of all data nodes cannot be controlled, network data cannot be manipulated and modified arbitrarily, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously.

❷ What are the three major public chains of the blockchain

Public chain, the abbreviation of public chain, means that anyone in the world can read it, anyone can send transactions, and transactions can be Obtain valid confirmation of a blockchain in which anyone can participate in the consensus process.

1. Top three public chains in the world
BTC, ETH, EOS (by market value) Three heavyweight products, representing blockchain 1.0, blockchain 2.0 and blockchain 3.0 respectively a stage.

1. Bitcoin BTC (Blockchain 1.0)
Bitcoin has emerged as a new type of digital currency and global payment network since its birth in 2009. BTC is also the most successful and mature application of blockchain , BTC’s reputation is much louder than blockchain in many scenarios.

2 . Ethereum ETH (Blockchain 2.0)
In layman’s terms, Ethereum is an open source platform digital currency and blockchain platform, providing developers with a platform to build and publish applications on the blockchain . Ethereum can program, decentralize, secure, trade anything, vote domains, financial exchanges, crowdfunding, corporate governance contracts and most agreements, intellectual property, and hardware-integrated smart assets.

3 . Yuzu EOS (Blockchain 3.0)
EOS is an enterprise-level blockchain operating system based on Bitcoin and Ethereum, which is easier to use and more powerful than the former. EOS provides all application developers with database account permission settings, execution scheduling authentication and network communication and many other functions.

2. The world’s three largest exchange public chains: Huobi Chain, Binance Chain, OKEx Chain
1 . Developed by Huobi, the world’s largest trading platform, Huobi Chain is the The independently innovative and regulated blockchain operating system for the financial field is based on the global asset digitization of blockchain and the infrastructure of the financial market. At the same time, based on the consideration of the long-term value injection of HT into a unified value carrier, HT will be the only underlying token of the Huobi public chain.
2 . Developed by Binance, the world’s second largest trading platform, Binance Chain started early in application and currently mainly circulates on DEX and asset chains. Binance Chain is a digital asset creation and exchange platform with BNB as the main chain token
3. AllDeveloped by OKEx, the third largest trading platform in the world, OKChain is a more scalable, high-capacity transaction and smart contract platform. OKChain is developed based on Cosmos-SDK and uses DPOS for consensus. OKB is the underlying token of the OKEx ecosystem.

❸ At present, what are the more reliable blockchain public chains in China

In the past, whenever we mentioned going to the blockchain, we would always think of foreign products , such as Ethereum, but when I talk about this topic again today, I will think more of China’s own blockchain technology.

At present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects are developed based on this, so I think the current global One of the general directions of the implementation of the project is the public chain project. It is still too early to talk about maturity. After all, Bitcoin and Ethereum are still very blocked. There are still many old problems that have not been solved, and many new problems will appear. The more well-known ones are Bytom, Ulord (the project is abroad, but the technical provider is provided by the domestic company Hunan Tianhe Guoyun Co., Ltd.), Quantum Chain, Xiaoyi NEO, Gongxinbao, etc.

Ulord is a peer-to-peer value transfer public chain. By building the underlying architecture of the blockchain and the digital resource distribution protocol, it supports third-party developers to build their own applications on top of its open source protocol, and cooperates with many industries. Partners work together to build a complete ecosystem of blockchain technology and applications.

Based on various rules and protocols created by Ulord, it is convenient to graft various application scenarios of digital resources including text, pictures, music, video, software, etc., providing information creators and consumers with direct docking platform. Third-party developers can build their own economic system in Ulord, or they can build various applications around Ulord, and use UlordToken in Ulord as the certificate in the system.

For example, an experience sharing platform can be built on Ulord, the experience sharer will price the published experience, the person who obtains the experience information trades on the platform, and every fee paid to the experience sharer will arrive immediately. Account; product promoters can publish advertisements on Ulord, price the advertisements, and those who are interested in the advertisements and click the advertisements can get a certain income and so on. Different from the previous mode of information transmission, which requires the help of platforms or other centralized institutions to spread and profit, the intermediate links are removed, and information providers and consumers are directly connected through Ulord, which ensures the maximization of the interests of the original creators.

❹ What are the blockchain software apps

ChainStore is a professional application store that integrates all mainstream applications in the blockchain and currency circles. It integrates exchanges, wallets, market software, tool software, blockchain information, blockchain games, industry applications, etc.

❺ What are the famous blockchain public chains in China

Little Yi Blockchain, Laikelib, etc. It seems to be very interesting.

❻ Blockchain public chain ranking (public chain speed ranking)

Before October 2018, the fastest seems to be Ripple, second only to EOS, After October, these public chains were basically silent in terms of speed, because Bitconch, based on many technical advantages, reached 120,000 TPS, which made the application possible. Therefore, the fastest public chain in the world is the fastest public chain in the world, and it can be said to be the leader.

❼ What blockchain apps are there

Blockchain apps include: NetEase Planet Base, Digital Chain App, Lianxiang Finance, Time Forest Blockchain Trading Platform, Blockchain Electronic Wallet, Ostrich Blockchain, GXS Wallet, Coin Wallet, Youling Wallet.

Each user can freely choose an application to build his own homepage, including but not limited to: Not limited to: souvenirs, live broadcast, sharing, community, service sales, commodity sales.

❽ What is the public chain in the blockchain

The public chain is also called “public chain”, which means that anyone in the world can enter the system at any time to read data, Send a blockchain that confirms transactions and competes for accounting. Public blockchains are often considered “completely decentralized” because no individual or institution can control or tamper with the reading and writing of data in them. In terms of application, the blockchain public chain mainly includes Bitcoin, Ethereum, Hyperledger, most altcoins and smart contracts. The ancestor of the blockchain public chain is the Bitcoin blockchain, which has the following characteristics :

1. Open source code

Upload the code to github, everyone can download the complete blockchain data and accept the test of the public.

2. Fully decentralized

Anyone can become a festival.� Every node is public, and everyone can participate in the calculation of the blockchain. No node is permanent, but phased, and no center is mandatory for nodes. Anyone 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, as well as the exact current state. Everyone can get economic rewards from it, proportional to the contribution made in the consensus process. These public chains are generally considered to be “completely decentralized”.

3. Develop decentralized applications

Program developers can easily develop decentralized applications through this public chain. The public chain can protect the rights and interests of users from the influence of program developers.

Extension information: Blockchain is a term in the field of information technology. It is essentially a shared database, and the data or information stored in it has the characteristics of “non-forgery”, “full traces”, “traceability”, “openness and transparency”, and “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid “trust” foundation, created a reliable “cooperation” mechanism, and has broad application prospects.
Advantages of blockchain: 1. Decentralization Blockchain uses peer-to-peer network technology to store data, uses distributed accounting and storage, and has no centralized hardware or management organization. The rights and obligations of all nodes are equal, so the downtime of any node will not affect the operation of the entire system.
2. The collective maintenance system is open, except that the private information of the transaction parties is encrypted, the system is jointly maintained by all nodes with maintenance functions, and anyone can query the blockchain data through the open interface and develop related application. Therefore, the information of the whole system is highly transparent.
3. Information cannot be tampered with. Once the information is verified and added to the blockchain, it is stored permanently. Generate an immutable, trustworthy database of chronological records to limit relevant violations. Therefore, the data stability and reliability of the blockchain are extremely high.
4. No need to trust the system Since the exchange between nodes follows a fixed algorithm, the participants do not need to trust anyone. As the number of participating nodes increases, the security of the system also increases. Therefore, the counterparty does not need to carry out their own trust through public identity, which is very helpful for the accumulation of credit.
Disadvantages of blockchain: 1. No privacy In the blockchain public chain, each participant can obtain a complete backup of the data, and all transaction data are open and transparent. If you want to know the account and transaction information of some commercial institutions, you can know all his wealth, as well as important assets and business secrets, there is no privacy at all.
2. Security Issues A major feature of blockchain technology is irreversibility and unforgeability, but only if the private key is secure. The private key is generated and saved by the user without the involvement of a third party. Once the private key is lost, nothing can be done with the account’s assets. With the development of new computing technologies such as quantum computers, asymmetric encryption algorithms may be cracked in the future, which is also a potential security threat to blockchain technology.
