Technical Specifications

The preliminary configuration prior to EOS.IO launch is hosted on the Google Cloud Platform ​. Google Cloud provides high availability, geographic distribution, and almost immediate on-demand scaling. EOSrock has launched primary and backup BP nodes on EOS testnet, with the following server configuration:

CPU: 64-core
RAM: 256 GB
Storage: 1 TB
Network: 2x 1Gbps
Operating System: Ubuntu 16.10
Geographical region servers: Germany [2]

Scaling Plan

EOSrock BP Node
Deployment Timeline

With team members in Serbia ​, Slovenia ​ and US, EOSrock plans to deploy stackable infrastructure in Tier 3 data center environments with highest levels of redundancy and security. The selected hardware surpasses requirements by designing a base configuration and scaling it up and out to match the anticipated number of users and transaction levels. [2]

High availability distributed build-outs insure that in case of a primary BP failure, a failover process to the backup BP node will be initiated with no service impact and downtime.

With one of the team members from the original Google Cloud Platform ​ architecture team, and SW engineer in Lisk ​ producer node role, EOSrock is capable of scaling the largest blockchain networks efficiently and fast. EOSrock will continue to improve performance and redundancy of its infrastructure based on constant benchmarking. [2]

EOSrock will be closely monitoring the processes and hardware across the distributed environments, by using in house built automation tools. [2]
