InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I also found this great simple library: https://github.com/nayuki/Bitcoin-Cryptography-Library I put a lot of hope in it, due to how small and straightforward it is. But I found it missing a couple of crucial primitives (I don't remember immediately which) to make the verification work.
