3) extremely difficult to tamper
Technical Features
1) to the center
Data verification block chain, accounting, storage, maintenance and transmission processes are based on a distributed system architecture, using pure mathematical algorithm rather than the central institutions to establish a trust relationship between the mass distributed nodes without trust, to achieve based center point to point of trust transactions, coordination and collaboration, providing innovative solutions to solve the centralized system prevailing high cost, efficiency and data storage end insecurity and other issues.
To the center can be understood from the network control functions and three perspectives:
(1) Network Perspective: refers to the center of a communication network system does not exist in the central affect other nodes connected to each other;
(2) Angle Control: control from the perspective of view, to the center system refers to a system having a super authority does not exist, the control can be "central node" other nodes;
(3) Angle function: the function point of view, the system refers to the center node function is to bear and the like, there is no special function indispensable "central node."
2) disintermediation
It features to the center of the block chain technology to some extent led to disintermediation form block chain ecosystems exhibited.
3) extremely difficult to tamper
Block chain technology is a universal participation accounting, participatory way to record and store transaction information, and jointly safeguard the transaction database, which has extremely difficult to tamper with, undeniable and can not be forged and so on.
4) Traceability
Block chain using chain block structure for storing data with a time stamp, thereby increasing the time dimension of the data, with strong verifiable and traceability.
5) programmability
Block chain technology provides a flexible script code system, allows users to create advanced smart contract or other decentralized applications.
6) safe and reliable
Block chain technology using asymmetric cryptography parties to the transaction of sensitive information is encrypted, only the nodes permission to access or use; at the same time, with zero-knowledge proof, consensus homomorphic encryption and other cryptographic tools, as well as distributed nodes powerful algorithms calculate force formed to defend against external attacks, which can ensure the block chain data with high security and effective protection of user privacy.
