BigBang Core Multi-Node Network


China, Xianggang, Guiqing – 05-03-2020 ( — 1-Blockchain Node

In blockchain networks, there are traditionally three types of nodes that provide different functions in the network. These node types are:Broadcast nodes: they only send out transactions and receive blockchain messages from third parties. They follow the most powerful mining drivers, called light wallets, and are widely used on mobile devices, or simply by people who do not want to download the entire blockchain.Complete nodes: To install the complete node software and, in addition to having the most secure wallet, it will need to download a copy of the blockchain and become a node in the bitcoin network. The transaction will therefore be issued, propagating the rest of the network and verifying that the consistency rules are met.Digging nodes: in addition to operating a favorite software digger, the digger must have a copy of the blockchain. In addition to mining bitcoin, which helps create new blocks, these nodes also publish and spread transactions.In theory, a complete blockchain could be executed on a single node, but since it would be stored on a single device, it is very vulnerable to situations such as power outages, hacks or system failures. The more complete nodes that run in the blockchain, the more resilient they will be in the face of such disasters. When blockchain data is distributed across so many devices, it is very difficult for a corrupted entity to delete all this data at once. Due to the global crisis, a large number of nodes suddenly dropped and became inaccessible, and in theory, a single node could keep the entire blockchain running. Even if all nodes are disconnected, it only takes one node with a full blockchain history to get back online and make all data accessible again, and these nodes are vulnerable to computer attacks that could change their functionality.2-Node Network Security for BigBang CoreBigBang Core nodes can be online or offline. Online nodes receive, save, and transmit all final blocks of transactions from other nodes, while unconnected nodes do not. When an offline node comes back online, it must first catch up with the rest of the blockchain by downloading all the blocks that have been added to the blockchain since that node was disconnected, a process often called blockchain synchronization.The BigBang Core network is a distributed block network of all nodes, with each node on the network having equal and peer-to-peer power. The nodes are connected peer-to-peer with the ability to independently complete block data and transaction verification. This peer-to-peer connection P2P network is the most important foundation of the blockchain data layer. It implements the underlying mechanism of nodes communicating with each other, connecting with each other, confirming the correct validity of data with each other in the network, and supporting the efficient and stable work of the BigBang Core blockchain system.3-DPOS Node Consensus MechanismConsensus refers to the process by which system nodes reach agreement, and the consistency of a distributed system is reflected in three aspects:- Terminate: all processes end in a finite number of steps and select a value, and the algorithm does not execute infinitely.- Agreement: all processes must agree on the same value.- Validity: the output is generated by the input rules according to the system rules and the output is legal.The consensus mechanism is the soul of the blockchain. BigBang Core’s DPOS consensus mechanism design determines whether it is possible to establish sound incentives to encourage more nodes to participate and to increase the decentralization of the system.The BigBang Core matrix technology is based on the DPOS consensus mechanism. This is a new approach to protecting the cryptocurrency network that attempts to address the traditional proof-of-work system for Bitcoin and the equity authentication system for peers and NXT. The DPOS consensus was originally proposed by the BitShares community. The main difference between it and POS consensus is that nodes select several agents, which are verified and billed by the agents. Compared to POS, DPOS can significantly increase election efficiency and achieve performance improvements at the expense of some decentralized functions.The mechanism consists of witnesses and trustees, who are responsible for the packaging of the block and the trustees for modifying the system parameters. The Certificate of Entitlement mitigates the potential negative effects of centralization through the use of witnesses (formally called representatives). A total of multiple witnesses signed up for these blocks and voted each time the network was used to vote.BigBang Core is more democratic than comparable systems by using a decentralized voting process. Rather than eliminating the need for all trust, DPOS takes protective measures to ensure that the person representing the network’s trust signature block performs this action correctly. DPOS eliminates the need to wait for a certain number of untrustworthy nodes to verify a transaction before confirming it.4-Distributed Node Network for BigBang CoreClusters of BigBang Core node allow multiple and efficient cross-chain transactions between node clusters without additional design. BigBang Core nodes can support countless sub-chains of parallel blocks, and blocks can be stored in a distributed manner. Nodes can expand sub-chain nodes infinitely, solving single-point performance bottlenecks to achieve unlimited TPS expansion. In a BigBang Core system with a large number of nodes distributed, any single node may become the hub of the phase, but there is no mandatory hub control. The influence of nodes to nodes passes through the network and a nonlinear causal relationship is formed.BigBang Core will build an architecture through a network of distributed nodes, allowing hardware from all corners of the world to form a parallel distributed network, confirming the authenticity and integrity of all IoT (Internet of Things) business data needs, such as commodity trade, services, sales and other business data through massive hardware nodes, and building a credit monitoring system for independent behavior and the interconnection of all things.
