01

Blockchain & confidential computing

Production trusted-execution and multi-chain systems — the through-line of most of my engineering.

TEE enclave server (Intel SGX + Gramine) for Ternoa's Secret-NFT protocol — remote attestation, P2P real-time key sync, and secure key management bound to the chain.

Rust · SGX · Gramine

diewan / csv-adapter

A multi-chain client-side validation adapter — anchoring state transitions across blockchain layers so state can travel with its own proof. Archived reference.

Rust

bitcoin-analytics

Exploration, analytics, and visualization over the Bitcoin ledger.

Jupyter

02

Cryptography & hardware security

Secrets that can be shared without being surrendered; circuits that leak more than they mean to.

vsss-wasm

Verifiable secret sharing — split a secret so any threshold of holders can prove a share is valid without revealing it.

Rust · WebAssembly

side-channel-attack

Tooling for smart-card side-channel analysis — reading the whispers a chip makes while it computes.

MATLAB

03

Topology & tools for thought

Reading structure — and shape — out of data and one's own notes.

simplicial-complex

Knowledge discovery for Obsidian vaults via topological analysis — building a simplicial complex over notes to surface higher-order structure and hidden connections.

TypeScript

N-Queens

A genetic-programming approach to the N-Queens problem. Where the notebook began, in 2015.

Clojure

04

Coordination for collective life

Systems that help small groups form, remember, and hold together — through perception, not prediction.

Zwischen

A coordination system for small groups: forming events, tracking participation, surfacing state, and carrying memory forward — without modelling users or steering outcomes.

More lives at github.com/zorvan and github.com/diewan. The 2015 origin — an N-Queens solver in Clojure — is kept in the archive.
