BigBang Core is a block system built on a P2P network. Similar to the current popular P2P digital currency system, it maintains transparent ledgers in a decentralized manner, and realizes independent security management and efficient flow of users' digital assets. The BigBang Core system is designed for IoT (Internet of Things, Internet of Things) data business requirements, using block technology to provide a decentralized security management platform for IoT data services, and to achieve high concurrency and low latency performance requirements required by IoT systems. BigBang Core organizes user transactions through security consensus and forms data blocks in chronological order. Unlike single-chain systems such as Bitcoin, BigBang Core uses a tree structure to store and arrange blocks, and can be forked to form multiple branches according to business types and data loads. The blocks between branches are independent of each other, and the new blocks are only related to their own branch data.
In the case of multiple branches, according to the business data flow, it can be distributed to multiple branch blocks. The resulting scalability and high concurrency are the basic performance required by IoT systems. The multi-branch structure of BigBang Core consists of a unique security main chain and many application fork chains. The security main chain is used to support the consensus mechanism of the whole network, and the application fork chain is used for actual business. The application branch chain can provide a minimum of 2 seconds of low-latency transaction confirmation. Users can specify the urgency of the transaction and pay the corresponding transaction fee to achieve low-latency business.

Project System Features

Tree structure
Unlike traditional single-chain systems such as Bitcoin, BigBang Core uses a tree structure to organize and store block data.
High Expansion
In the face of the massive data transactions of the Internet of Things, the horizontal expansion of the entire system is realized by relying on the infinitely expandable tree structure.
High concurrency
The number of transactions per second (TPS, Transaction Per Second) of the application branch chain can reach 5200, and a transaction can be confirmed on the chain within 2 seconds at the fastest. It can meet the scene characteristics of frequent data transactions and low latency under the Internet of Things.
Quick data access
Through good system design, stable interfaces and back-end services are provided for both streaming data and persistent data, so that data can be quickly uploaded to the chain.
Data notarization
BigBang Core stores data identification and circulation records on the chain. Once the data identification is on the chain, it cannot be changed. It can provide data consistency certification and notarization for demanders and providers information.
Internet of Things Value Transfer Platform
As the underlying infrastructure of the Internet of Things technology, it provides a stable and reliable technical platform for data transmission and value transfer on the Internet of Things.

Project network description

The BigBang Core network consists of nodes running BigBang Core software to form a P2P network. The overall network architecture of BigBang Core can be divided into three layers: node network layer, terminal service layer, and IoT terminal layer.
The node network layer is composed of nodes running the BigBang Core core node program. The nodes synchronize and verify blocks and transaction data, and organize block data by consensus. The terminal service network forms a distributed terminal background to provide access services for IoT (Internet of Things) terminals.
In order to support the huge IoT (Internet of Things) business, the node network and the terminal service network together form the BigBang Core service platform. The IoT terminal layer includes smart sensors, controllers, and mobile terminals, embedded with light client programs, and locally saving private keys to complete transaction construction and verification.
