Description

Blockchain technology represents a new paradigm for applications in fintech and beyond, one that requires new approaches to age-old problems—how do you track criminals, derive BI insights, and fight fraud in a blockchain-powered world? While the decentralized nature of the blockchain presents challenges to easily understanding the movement of money, the immutable, shared ledger also represents a tremendous opportunity for behavioral analytics at scale. As blockchain adoption continues to accelerate, organizations big and small need to understand the systems required to efficiently and quickly analyze the wealth of complex information available.

Since 2014, BlockCypher has been on the forefront of blockchain infrastructure. BlockCypher’s Bryan Cheng and Karen Hsu describe how they built machine-learning and graph traversal systems on Apache Spark to help government organizations and private businesses stay informed in the brave new world of blockchain technology. Bryan and Karen also share lessons learned combining these two bleeding-edge technologies and explain how these techniques can be applied to private and federated chains.

Topics include:

  • The unique challenges inherent with blockchain data and identities
  • The architecture BlockCypher uses to power blockchain analytics
  • Techniques and tools used for particular types of blockchains
  • Integration of discrete machine-learning, graph traversal, and heuristic components into a coherent pipeline combining machine and human intelligence
