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!","time":1750279245,"title":"In-Memory C++ Leap in Blockchain Analysis","type":"story","url":"https://caudena.com/the-in-memory-c-leap-in-blockchain-analysis/"}]]
