Well known foreign blockchain websites
In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about 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 need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc
ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners 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 digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system
for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>
Blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
