# About CUN
# Intro of CUN Blockchain Network
Blockchain is a decentralized ledger technology. It is another revolutionary innovation of Internet technologies after artificial intelligence, big data, cloud computing and Internet of things. Blockchain technology promotes the transformation of production relations in the development of digital economy. With the consecutive waves of digitization in recent years, network applications such as Ethereum and Bitcoin have sprung up in the global digital economy system, promoting the rapid development of blockchain technology. In the continuous innovation and evolution, after iterations during more than a decade, blockchain technology has gradually become pivotal in digital economy globally after COVID-19. The Internet enters a new era. Coopunion Network, abbreviated as CUN, is a distributed network infrastructure that evolves from Ethereum. It aims to build a blockchain network and ecosystem with high-performance, high stability and low cost, to improve users’ experience, to reduce use cost, and to protect users' assets in digital world. Ultimately CUN will be a DAO-governed network.
Innovate from the underlying technology, CUN has made technical improvements in consensus mechanism, incentive mechanism, privacy protection, identity verification and multichain cross-chain respectively, which characterize CUN with high performance, high flexibility, high decentralization and incentive balance. Join and maintain CUN, users will receive Coopunion Network Point（abbreviated as CUNP, which can be used to pay Gas on CUN, and is also the perpetual certificate that quantifies users’ contributions , as well as the tool for community governance) . Compared with other main blockchain projects, its incentive rules and election mechanism imply higher efficiency and equity.
Cooperation creates value.

# CUN Network Performance
- Block time：3s
# CUN Technical Characteristics
CUN adopts a progressive evolution route for decentralization. The network begins with PoA consensus before evolving to PoA + PoS consensus, and improves to PoS consensus eventually so as to ensure the decentralization and security of the network.
CUN applies hierarchical PBFT algorithms in the mainnet to improve PoS consensus mechanism. In the meantime the mainnet and applications focus on protection of privacy and personal data entitlements.
# CUN Economic Model
The value of CUNP comes from the CUN network effect. By bringing together all the institutions and individuals around the world who wish to do business on blockchain via CUN, they voluntarily provide services and access services based on CUN, and form a global on-chain market matched by CUN.
# Evolution of CUN Network
At the launch, CUN “Origin” network is a Layer1 network with mainnet Coin, with PoA consensus as access mechanism to directly elect multiple trusted nodes to participate in the launch and maintenance of the network, forming a collection of nodes. These nodes need to stake a part of CUNPs, and block collection, packaging, consensus and verification are all performed by nodes in the set. In the first stage, CUN is of great network stability，high consensus performance is also a pivotal feature of this stage.
When the network node scale and the CUNPs held by the community are accumulated to be eligible for stake voting, CUN will enter Cape of Good Hope Network from Origin Network. The Cape of Good Hope Network is a transitional network to Next Generation Network, with PoA+PoS as the access mechanism. By combining the PoA+PoS consensus, while expanding decentralization, the stability and high performance of the network are guaranteed.
When the network scale and CUNP distribution gradually stabilize, and the node scale and community scale further expand, CUN will enter the third stage New Generation Network. In this stage, PoS is used as the access consensus, and a random algorithm with equity as the weight is used to determine the block producer.
The most significant feature of the network is the high degree of decentralization, and is planned to be DAO-governed at this stage.
