Blockchain Infrastructure
I build the software blockchains run on.
I work on validator clients, gossip networks, and shielded payments. Mostly Solana and PIVX, plus a long tail of chains most people have forgotten.
Solana
Validator clients · gossip · network telemetry
Most of what I do now. I run and patch the Rust validator clients, reimplemented the gossip protocol from the spec, and built a set of tools that measure the network: latency, vote credits, block production, leader timing, skip rates.
PIVX
Core full node · shielded payments · wallets
I've contributed to the PIVX C++ full node and the tools around it for years. Sapling SHIELD privacy, cold-staking, masternode governance, and the wallets, explorers, and payment rails on top.
Blockchains
Bitcoin-family · Substrate · Ethereum · wallets · pools
Ten years of chains, plenty of them dead now. Bitcoin tooling and explorers, multi-currency wallets, Substrate nodes and relayers, an Ethereum light client, mining pools, Nostr clients, and a pile of altcoin forks.
The Registry
Everything I've worked on, not just what's on GitHub
An index of the projects on my machine. Forks, experiments, one-off tools, dashboards, half-finished ideas. Filter by ecosystem.
I work close to
the protocol.
Consensus, gossip, mempools, shielded notes, masternode quorums, vote credits, skip rates. That's where I spend my time. Usually with a validator under load and a profiler open, because the spec and the running code disagree.
Most of it never ships to a landing page. It's the monitoring, exporters, and node patches that run in the background and flag when something breaks.
