In-Memory C++ Leap in Blockchain Analysis
By
caudena
Hey HN
We’re the core engineering team at Caudena (which is used globally by investigative and intelligence agencies, including: Europol, Interpol, BKA, DHS, IRS-CI, FBI, NPA and others), and we just released the technical details behind Prism - our real-time, in-memory C++ database for blockchain analysis.
To tackle the massive scale and complexity of blockchain data, we had to get creative with low-level engineering:
- We utilize barebone servers with 2TB RAM and 48 Cores.
- Implemented lock-free concurrent data structures
- Developed a custom memory management system
- Leveraging CPU-level vectorization
- Built a custom in-memory columnar/graph database from scratch
We’d love to AMA about:
- the engineering choices we made
- crazy optimizations that paid off
- pitfalls we hit
Ask us anything about scaling, memory trade-offs, building real-time analytics on immutable data, or the crypto-forensics space.
Looking forward to a great convo!
