1.2.1 Permissioned Services

BSN is continually adapting most of the mainstream permissioned blockchain frameworks. On the BSN portal users can deploy DApps on any public city nodes based on the type of selected framework and the number of peer nodes. The number of peer nodes per application can be up to 60 and can be distributed among public city nodes based on different cloud services. Users can easily complete the DApp deployment process by uploading smart contracts and configuring the corresponding parameters. This service mode allows developers to focus on business innovation, smart contract programming. All work related to environment construction, system maintenance, application deployment, node transmission, and network configuration is done by BSN.

The pricing strategy for the Permissioned service is based on three resource elements of each peer node of the published application. The three elements are TPS, storage, and data traffic. Among them, TPS and storage in the BSN portal are pre-paid, while data traffic will be charged based on actual usage. This pricing strategy is designed to minimize resource costs and provide users with the best services. Based on the data provided by the BSN portal, if a user deploys a three-peer Fabric DApp, and each peer node supports 10TPS and 10GB storage capacity, the monthly fee is only 20 USD.

The pricing strategy of BSN dedicated node services is based on the host configuration, hard disk, and data usage of the cloud platform selected for the service, where the host configuration and hard disk are prepaid, and the data usage fee is postpaid according to the actual amount incurred; the pricing strategy of interchain services is postpaid according to the actual number of cross-chain calls occurred; the permissioned services, oracle services and interchain services provided by the BSN Testnet services are all free of charge.
