Part III Technical Preparations of Block Producing Candidates

1. Hardware Configuration and Structure

1) Summary

As the project plan and framework diagram, this article aims at analyzing all available knowledge and conducting the project plan in a steady and orderly way to ensure that the project can be later implemented according to the project plan and framework diagram.

2) Project Background

Starting from scratch, the project requires a comparatively minimal system. Considering the fact that once the project goes online (the block reward starts), the service will face huge amount of input and output data, we should leave room for the scale-up (upgrade configuration) and scale-out (add more equipment) of the server.

For any type of blockchain product, the protocol layer must include various sections such as P2P network, encrypted signature, data storage and distributed algorithm. The application layer of any type of blockchain product should also provide basic applications, such as digital wallets and client explorer.

The minimal system can easily be equipped with a large memory space after compression. A master server with better input/output can easily support the system. Considering security and stability issues, every minimal system should be equipped with a backup system as well. The configuration of the backup system could be slightly lower (a.k.a. a slave server). Regarding system security issue, it is recommended to install a WAF before connecting the system, and then connect a cloud load balancer with the system. Regarding the hardware equipment of the cloud load balancer, we can choose equipment like F5 or any other equipment with same functions, but the disadvantage here is that the hardware equipment mentioned above can be very expensive. Another alternative solution is that we can use WAF to undertake the function of cloud load balancing, but it only provide very weak cloud load balancing capability). Regarding the software equipment of the cloud load balancer, we can adopt LVS open source solution (the solution requires a server to provide load balancer service). After all above procedures, the system that provides service is finally connected for operation (1 Master + 1 Slave equipment). The entire system is thus basically completed.

In any case of single point failure, the minimal system is considered as a single point. With sufficient budget, we may consider establishing a system with the same configuration in another location. With insufficient budget, we may adopt an alternative solution, which is implementing our complete plan on a cloud host. The disadvantage of the alternative solution is that the alternative solution is beyond our control and that its functions may be hindered by the upgrade of cloud host platform and the change of other relevant policies.

In the minimal system mentioned above, any single Master and Slave server plays the role as a full node. With sufficient budget, we may consider to add an extra server that plays the role as storage node in every minimal system for the independent storage of data, which in turn ensures the security of data redundancy.

3) Diagram

NOTE: The WAF and the load balancer in the above framework diagram can be integrated, as WAF provides weak function of cloud balancing. Every framework is going to be in a different jurisdiction.

4) Network Plan

As is shown in the framework diagram above, every minimal system requires an access layer switch. It is recommended to adopt type H3C S5130 switch with 48 ports and two of these switches are required (one for spare or the setting of Intranet. After connecting to access layer switch, we then connect the system to WAF, and then connect WAF with load balancer, and finally we connect load balancer with Master server and slave server. (Actually, the data flow is exchanged through the same switch. We may adjust the setting of Intranet for Intranet data flow exchange and thus distinguish between Internet data flow and the exchanged data flow of the switch).

Switch and VLAN Division:

The switch manages VLAN (Switch manages IP Network)

The server connects to VLAN (Internet and Intranet)

IDRAC manages VLAN (Dell IDRAC manages the network)

5) Server Configuration List

Master Server:

PowerEdge R730xd

4 CPUs Intel® Xeon®

128G * 2 (2400 MHz)

300G*2(System Disk) 7.2k rpm

512G*1(data disk)SSD

512G * 1(Data Disk) SSD

Dual Power

Switch: H3C S5130 48 Ports * 2

WAF: WebRAY Ray-WAF-1006P(The purchase of license is required)

6) The implementation of System Initialization

All servers in the system adopt CentOS system, it is recommended to implement version 6 or version 7 of CentOS system based on actual requirements.

Configure different system kernel optimization parameter based on the role of server

Strictly control the permission of server account.

Launch IPTABLES service and add IP whitelist and server ports. Add SSH and allow restriction to enhance the configuration of security settings.

The remote login activity conducted by the server can be reached through the following procedures: First, apply for vpn dial-up by configuring the openvpn account of the servers that require vpn login. After finishing the dial-up process, the login request is transmitted to the access gateway through Intranet IP, then through to the proxy server, and finally reaches the target master server (through Intranet IP).





All above operation procedures can be realized through Teambition. The operation procedures are thus to be conducted through work sheet system.

7) Monitoring Service and Daily Inspections

We can provide servers, network switches, asset system, monitoring service and alarming system for abnormal events. We can develop asset system and monitoring service, or we can also use the open source service configurations that are currently available.

The granularity of the monitoring system and the master monitor server is divided into two categories, which are system granularity and service granularity.

The monitor server monitors following system services: CPU, Memory, Hard Drive, Network, Cloud Load, System Log.

The monitoring service monitors service ports

Daily Inspections and Maintenance: Daily inspections and maintenance are the supplement and double confirmation of the monitoring service. The daily inspections and maintenance enhance the security and stability of the platform’s operation and help us to detect any problems at the very beginning, solve the problems immediately and adopt preventive measures regarding such problems. The contents of daily inspection mainly include:

The inspections on servers and hardware equipment. By reading the data provided by the thermometers and hygrometers located in all measuring points of the server room, the service engineers in the server room check the temperature and moisture of the server cabinets on a regular basis and control the operation environment of the server room. By checking the colors of the indicator light on the control panel of the server, our engineers can check the operation status of the server and hardware immediately. The inspection on access gateway: Through the system log inspection function of the control panel of the access gateway, we can obtain various types of information, including the IP source of the users, login time, the history records of the operations that login users have conducted and login duration etc. Server system inspection: We can conduct server system inspection by logging in our server and checking abnormal error information, the usage status and tendency of CPU, memory and disks on a regular basis for the double confirmation of monitoring service. Security inspection: Security inspection aims at checking relevant information such as the operation status of the firewall and user login status on a regular basis. Security inspection is the double confirmation of monitoring service.

2. Future Upgrades and Scale-ups
