What is the meaning of blockchain protocol online
blockchain is a shared database. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on
main 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
2. Openness. The foundation of blockchain technology is open source. In addition to the private information of all parties to 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
3. Independence. Based on consensus specifications and protocols, 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
extended data
application direction:
1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance can achieve remittance in seconds e to decentralization. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance
2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning

generally, protocol level assets can also be used as local procts of the protocol (no platform required!) bitcoin is a good example. Bitcoin (capital B) refers to the agreement. The agreement depends on the local asset: bitcoin (small b). This local asset is also used as the end proct: it's the user's means of payment, the store of value, and (to be honest) a degree of hype. Please note that bitcoin does not really provide a platform. It's not very friendly for developers trying to build new procts on it< On the other hand, Ethereum has three levels. It's an agreement that provides the basic rules. This is a platform that enables developers to build new procts on the system. Moreover, because its agreement contains a local asset, it also gets a built-in proct (in the form of ether)
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
Anyone can own bitshares by investing in bitshares PTS and bitshares AGS. AGS (angel shares) is a share of angel investment fund, which is used to support the research, development and creation of technologies related to bitstocks. A total of 10000 AGS will be given to those who donate Angel funds on the same day according to the proportion of donation to the donation on the same day. Bitshares PTS is a clone of bitcoin that allows you to mine and trade your support for the bitshares ecosystem. Bitshares AGS and bitshares PTS both contain a social consensus, that is, in the future, all bitshares blockchains should allocate at least 10% of each to AGS and PTS shareholders in Genesis block to give back their support to the ecosystem of bitshares

analysis
the essence of blockchain
technology is as follows:
blockchain is essentially a value based on P2P
transmission protocol
, we can not only see P2P, but not value transmission
similarly, we can not only see the value transmission, but also the underlying technology of blockchain.
