D) Technical Specifications

Before 3rd of June, in order to maintain the robustness and reliability of testnet server, we will use two cloud based servers in block producing.

  • Main Server
    Intel Xeon E5-2696 v4 @ 2.20GHz
    CPU:22 vCPU core
    32GB RAM
    SSD:LOCAL PCIe 3.0
    NETWORK:1000 Mbps

  • Backup Server
    Intel Xeon Platinum 8173M @ 2.00GHz
    CPU:28 vCPU core
    64GB RAM
    SSD:LOCAL PCIe 3.0
    NETWORK:1000 Mbps

Those two servers will be based on AWS servers in the US.

Scaling plan after June 3, 2018:
After the 3rd of June, we will keep up with the rising demand of EOS, and cooperate with well-known blockchain solution providers to build bare metal server that is robust and highly scalable. The provisional hardware Specs:

  • Intel Xeon E7-8880 v4 @ 2.20GHz
    CPU:22 vCPU core
    32GB RAM
    SSD:LOCAL PCIe 3.0
    NETWORK:1000 Mbps

In circumstances when error occurs at nodes, the process will be switched to redundant nodes in order to maintain uninterrupted block production and to never miss a block.

Live Upgrade of Cluster
Upgrade to servers can be performed while the cluster is running live without affecting block producing process, as a result of multiple points redundancy used in our system. Machines that are upgraded will be thoroughly tested before being reconnected.

Elastic Load Management
The system supports high elasticity, as upgrades to the system that is used to deal with any potential demand surge, will not affect the operation of block producing.

Load Balacing
Load will be processed by the cluster load balancer before it is sent to processing nodes, which are dynamically assigned with weights, to maximize overall performance of the system.

D) Community Benefit Plan

We define ourselves as candidate from the community, by the community, for the community. EOS WTZ believes that, as a block producer, contributing to community benefit is a responsibility of same importance as block producing. Both WTZ Blockchain Academy and EOS WTZ are self-funded, which allow us to make decision only for community benefits.
EOS WTZ is Operated by WTZ Blockchain Academy, one of the top blockchain content producers in China. EOS WTZ has a strong community supporting team, with first hand information about concerns and demand of our community members. This is the very foundation of EOS WTZ, a block producer that comes from the community, and the reason why EOS WTZ will be successful with its community benefit projects, as listed below:
