Thank you for your continued support of the NetFlowCoin Project. NetFlowCoin has reached 845599 blocks and cumulative traffic of 30 petabytes.
The goal of NetFlowCoin is to build a brand new global network communication service and application service platform jointly built and shared by producers/consumers by integrating SDN/SDVN and blockchain technology. It provides direct, simple, low cost, high performance basic communication services and various value-added service markets for service providers and consumers, such as enterprises and individuals.
By mapping DAPP/APP service flow to effective network flow, NetFlowCoin connects up the chain and down the chain, so as to realize the digitalization of real world assets and the digitalization of virtual world assets, thus forming the “blockchain ←→ network” value ecological closed loop and creating value for each role in the ecosystem. Let the vision of the “meta-universe” really fall to the ground.
SDN (software defined network) originated from Stanford University’s “Clean State Program.” This research project began in 2006, and it was there that the concept of SDN was formally proposed. The innovative software defined networking architecture defines and controls the network through a form of software programming. SDN is considered revolutionary in the network field and is widely used today.
SDVN (software defined virtual network) is derived from the re-innovation of SDN technology. It adopts Multicode packet encryption technology, Multilayered technology, Network Slicing technology, DLT technology, Next-Hops technology and other technologies to quickly realize network-to-network, point-to-network, and point-to-point secure private networks. Through SDVN, NetFlowCoin establishes a secure private virtual network for the Internet.
SDVN technology is a reliable and tested network architecture that has been used by millions of users and large-scale enterprises for over a decade. NetFlowCoin builds a cryptoeconomic system based on SDN/SDVN technology, and creates a distributed flow market for mapping the actual value of application services.
NetFlowCoin uses a dual consensus mechanism of Proof of Stake (PoS) and Proof of Flow (PoF). NetFlowCoin’s unique consensus mechanism and economic model aims to achieve three goals:
The majority of blockchains award tokens to block producers to encourage block mining. This ensures the fidelity of the distributed ledger and protects the network. The singular driver behind these consensus mechanisms is block generation. The consequences of networks like Bitcoin and Ethereum are massive energy wastes, barriers to entry, and centralization of resources.
In a public decentralized blockchain like NetFlowCoin, the long-term success of the network depends on the people. Each node is responsible for maintaining the operation of the entire system. To earn rewards, NetFlowCoin nodes contribute their time and resources to ensure the veracity of ledger data on the blockchain.
As with most blockchains, the consensus mechanism is designed to reward nodes who enrich the network and punish bad actors.
Proof of Stake
NetFlowCoin’s unique PoS mechanism functions by selecting witness nodes according to an equity algorithm set across four different candidate pools. The PoS reaches consensus by validating on-chain transactions, bookkeeping, and block generation.
Proof of Flow
Under NetFlowCoin’s PoF, users are incentivized and accurately rewarded for their off-chain contributions to the infrastructure, performance, and stability of the SDN/SDVN network. The PoF consensus algorithm measures and converts a node’s flow into on-chain value in the form of NetFlowCoin tokens. PoF covers two aspects of consensus, including static resource capabilities (bandwidth support) and dynamic service work (application data flow service).
Flow is a value conversion medium, whose characteristic is non-attribute, the full participation of flow and high adaptability in the traditional “customer-network-service” model.
NetFlowCoin’s unique Proof of Stake departs from the traditional PoS. The mechanism preselects four candidate node pools with different winning ratios (aka, a “multi-house system”). In each round of witness node elections, 21 nodes are selected from the four pools according to NFC’s equity algorithm. Block rights (i.e. witness nodes) are held in check with a debating algorithm to ensure that the block rights will not be dominated by certain fixed nodes.
Witness nodes are required to complete their work within the next 7 days, and they will take turns rotating according to a random block generation cycle. Each witness node can only complete block packaging in their specified block generation slot in order to receive the corresponding block’s generation rewards.
NetFlowCoin’s Proof of Flow consensus algorithm is based on combining static bandwidth support and dynamic flow work.
In the PoF design, the purely computational PoW algorithm is abandoned, and the proof of work that matches the actual market and real service is adopted, that is, the service workload provided by the service provider is measured by SDN/SDVN traffic, and the network security and robustness are taken into consideration. For static bandwidth resource nodes that have not generated traffic but have contributed to the scale of the network, we will also regularly reward them to incentivize the entire network nodes.
Traffic work rewards are based on the mining reward mechanism based on the valuable upstream traffic actually generated by each node in the system. Traffic is used as dynamic data. After the corresponding service is completed, the traffic generated is rewarded to the service provider in NFC mode.
The bandwidth support reward is a mining reward mechanism based on the high-quality bandwidth support provided by the traffic node for the network. At each reward window, the blockchain system will issue rewards to all high-quality static bandwidth providers in the entire network to incentivize their major contributions to the diversity and high quality of the network.
As the incentive layer of the SDN/SDVN network, NetFlowCoin is the first project to achieve blockchain-network integration. It works at the IP network communication layer, which is lower than the application layer-based blockchain implementation method, and provides security and universality for DAPP/APP A solid foundation for flexibility and scalability. The PoS consensus algorithm can eliminate the energy requirement of proof-of-work. The innovative PoF consensus that uses traffic as a proof of work benefits from the hierarchical nature of IP networks and application systems, allowing any application to smoothly connect to NetFlowCoin’s SDN/SDVN network, thereby quickly opening up the chain on-chain and off-chain bridges. The most important thing is that any application system needs to communicate on the network. Without a network, there is nothing, and NetFlowCoin itself is a true distributed network.
NetFlowCoin uses a dual token model: FUL and NFC
What is FUL?
FUL is a convertible settlement token anchored to the price of the U.S. dollar. The FUL token covers the basic communication fees of the SDN/SDVN. FUL cannot be used to transact between wallet addresses. FUL binds to a user’s address. It can only be converted into NFC tokens, or vice versa. If a user wants to withdraw unused FUL and cash out to another wallet address, they must convert the FUL into NFC tokens.
The FUL token can be viewed as the bridge between the real and virtual world. NetFlowCoin users can use FUL to pay for the resources of the SDN/SDVN network. Alternatively, users can contribute their idle bandwidth to the network in return for NFC tokens based on the bandwidth reward algorithm.
The FUL token facilitates the movement of value between the on-chain and off-chain worlds, and the conversion between FUL and NFC tokens are according to market prices.
What is NFC?
NFC (also “NetFlowCoin”) is the native token and the only medium of exchange in NetFlowCoin. The NFC token is issued through the local blockchain via the PoS and PoF consensus mechanisms. The NFC token has a fixed supply, and will never surpass 2.1 billion coins.
NFC is the base currency of the NetFlowCoin project, and the lifeblood of the NetFlowCoin economy and ecosystem. NFC holders have the ability to participate in the PoS consensus and effect governance by voting for witness nodes or forging new blocks as a witness node.
Traditional proof of work mining requires a lot of electricity and expensive mining hardware. While the vast majority of blockchain mining exists for the sake of mining, this has no practical application value. NetFlowCoin provides users with block mining, flow mining and bandwidth mining via our unique consensus. Miners can choose different mining methods according to actual needs, and mining does not cost exorbitant energy or computing power. NetFlowCoin is green and energy-efficient. NetFlowCoin values real applications (hence our tagline, “service is mining”). Users get rewards when they provide real and valuable services to the NetFlowCoin network. The combination of natural and real application is what we believe to be the future of the blockchain.
