The concept and characteristics of blockchain

1.
According to reports, blockchain has the advantages of decentralization, distrust and tamper proof
compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

2. The biggest feature of blockchain is "decentralization"
3. These characteristics make the blockchain technology can be applied to many instries. The SMIC blockchain service platform launched by Changsha high tech Zone also solicits enterprises to go on the chain, which is a blockchain + public service mode.
4. Blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid. When the concept of blockchain was hot, many related top domain names were registered and used as blockchain platforms.

5. Blockchain has the characteristics of decentralization, non tampering, irreversibility and anonymity
Decentralization: because there is no central ruler in the whole network. The system relies on the fair constraints of multiple participants on the network, so the rights and obligations of every node are equal, and every node will store all the data on the blockchain. Even if the node is damaged or attacked, it will not pose any threat to the account book
tamper proof: ensure that information or contracts cannot be forged. If the account book is in someone's hands, the possibility of fraud is very high, but everyone has an account book. Unless more than 51% of the people in the whole game change an account, any tampering will be invalid, which is also the advantage of collective maintenance and supervision
irreversible: the information on the blockchain must be irreversible and cannot be destroyed at will. The system is open source, and the whole system must be open and transparent. Therefore, after a transaction is broadcasted across the network, it will be successfully recorded with more than six confirmations, and it is irreversible and irreversible. Note: imtoken is the confirmation of 12 blocks
anonymity: the identity information of each block node does not need to be announced or verified, and the information can be transferred anonymously. For a simple example, you initiate a transaction to a wallet address on the blockchain, but you can't know the exact person behind the address, or your private key has been stolen by a hacker, and you can't know who the hacker is from a wallet address.
