24 alternatives to Password-less authentication via Ramanujan's 1/π series and Nvidia-B200

This preprint introduces a groundbreaking, zero-latency bank interaction framework that solves the Memory Wall problem in cybersecurity. By replacing memorized secrets with Silicon DNA (S-DNA) and securing the transaction layer with Ramanujan's transcendental 1/pi series, we establish a hardware-nat

A hash array-mapped trie implementation in C▲171
Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

Open-source code for a private, infinitely scalable, PQ-secure L1 layer▲7
For the past few months, I’ve been working on a new Layer 1 blockchain designed to solve what I see as the fundamental trilemma in the space: achieving strong privacy, infinite scalability, and post-quantum security simultaneously. The result is NERV: a private-by-default, horizontally scalable blockchain that replaces Merkle trees with 512-byte neural state embeddings, proven inside Halo2 circuits and attested in hardware enclaves. Key technical innovations: Neural State Embeddings Instead of Merkle trees, the entire state of a shard is compressed into a 512-byte vector using a transformer…

AES-256 brute force using structured logic (UUIDs and xy = x/y rule)▲11
I’ve been experimenting with structured logic as a way to frame search spaces — not in an academic way, just as a personal project. I wanted to know: what happens if you initialize a brute-force run with a simple equality like xy = x / y? Not as a filter, just as a logical ignition point. I used AES-256-CBC encrypted files with UUID passwords and tested against a 1 million UUID space. It cracked it in under 40 seconds. Then I scaled it to a 1 billion UUID range, and it still found the key without issue. This isn’t a crypto tool, and I’m not trying to solve any cryptographic problems.…

I Built a Groth16 ZK-Proof Verifier from Scratch Using Rust▲6
I've always been fascinated by cryptographic principles, so I decided to dive deep into zero-knowledge proofs and implement a Groth16 proof verifier entirely in Rust. This project validates cryptographic proofs and demonstrates how succinct, verifiable computations can be achieved. Using Rust's powerful libraries like arkworks, I implemented pairing checks, public input commitments, and proof validation logic while ensuring the code remains modular and efficient. I handled the complexities of affine group operations, scalar multiplications, and optimized public input verification to make…
