siv2r/README.md

Hello there, I am Sivaram - aka siv2r

I'm a cryptography engineer currently working on libsecp256k1, the library powering Bitcoin's digital signatures. Most days, you'll find me implementing or reviewing cryptographic protocols like FROST Signing, ChillDKG, Schnorr adaptor signatures, and Batch verification. In short, I spend my time making math do some pretty cool things. My work is supported through open-source developer grants, and right now, I'm grateful to be a Spiral grantee.

I'm particularly fascinated by provable security in cryptography and am steadily developing my expertise in this area. Publishing a research paper is one of my big aspirations. Additionally, I run a Substack newsletter called Nonce Sense, where I simplify cryptographic concepts and share updates on my work.

I graduated in 2023 with an Integrated Masters (BS + MS) in Mathematics and Computing from IIT Kharagpur. Outside of work, you’ll likely find me lifting weights, binge-reading a novel, or daydreaming about playing basketball more often.
