Figure 1: The NCCD Data Science Platform includes several core components from Hadoop for data storage, ingestion, and analysis. Other core infrastructure components, such as Apache Zookeeper and Ambari, are also used to support the platform. A high-performance cluster and GPU-enabled nodes for data analysis were integrated into the platform through installation of the Hadoop client applications.

Figure 2: TrialChain workflow and integration with the public Ethereum network. A) A master node is initially deployed to create the blockchain and assign initial permissions. Subsequently, additional client nodes can be added to the network either locally or, with proper permissions and network access, at remote locations. TrialChain services are deployed within individual Docker containers along with MutliChain client nodes to provide local access and data replication. B) The TrialChain administrative portal periodically synchronizes the most recent blockhash, which represents the current chain state, with the public Ethereum network.

Figure 4: TrialChain architecture and workflow. After acquiring data assets, the file hashes are submitted to the TrialChain platform and files are stored within the NDSP. Assets are created within the local blockchain and periodically synchronized to the public Ethereum network. Users can verify the status of the network and file authenticity through the administrative portal and remote clients can be configured to allow for further data distribution.
