openblockchaininfo/spark repository overview

⁠openblockchain: Spark

Spark is one of the microservices which comprise the openblockchain application.

⁠Architecture

The project is managed through the openblockchain⁠

The project is split into several services:

• Cassandra persists the data: blocks, transactions, and visualisations (analysed data).
• Bitcoin is used to connect to the Bitcoin blockchain. It's a simple Bitcoin Core node whose role is to index all the blocks and transactions and make them consumable through a HTTP JSON RPC interface.
• Scanner⁠ connects to the bitcoin service through its APIs and stores all the blocks and transactions in the Cassandra database.
• Spark⁠ analyses the Bitcoin blockchain data stored in Cassandra.
• API⁠ is a REST interface that allows clients to consume the data stored in Cassandra.
• Frontend⁠ is the web app used to explore the blockchain and visualise analysed data.

Each service contains 1 or more containers and can be scaled independently from each other.
