Constellation

Constellation is a protocol that employs a directed acyclic graph (DAG) architecture to achieve consensus theoretically capable of infinite scalability. Launched in 2017, Constellation's goal is to enable secure big data processing and allow connection to external datasets through APIs. Its approach involves a serverless architecture to address common blockchain problems such as scalability and centralization. The DAG protocol, complemented by custom state channels, is designed to evolve smart contracts by integrating data sources into distributed ledger technology (DLT)​​.

Constellation's unique mission is to process big data with high scalability, easy integration, low transaction fees, and robust security. It aims to efficiently handle large datasets in a secure and cost-effective manner. The network's scalability is directly proportional to its user base, increasing bandwidth as users join. Constellation's consensus model, proof-of-meme (PoM), rewards and selects nodes based on reputation. Its smart contracts run on a Java Virtual Machine (JVM), offering functionalities akin to Ethereum's smart contracts but with more complex logic​​.
