A certificate that rides the gossip — and why I moved it

“The tidy, clever mechanism — trust that rides the gossip and survives a relay — lost to the boring one that checks the credential where it gets spent.”

Keeping a node's name across a restart

“The data dir isn't where the node keeps its identity. The data dir IS the identity — which is why the scariest bug was a five-second timer.”

The relay is a postbox, not a peer

“The relay is an untrusted postbox: you trust it to forward, not to read or vouch. The keys do the vouching, point to point, direct or relayed alike.”

Hunting a connection leak the soak test wouldn't explain

“When a leak resists reasoning, stop reasoning and instrument it. A spawned-vs-finished counter found in minutes what hours of reading the reap path missed.”

Open-sourcing the Rust Distributed Mesh

“Not a library to take and use. A kit to read while you're paying the same costs I just paid.”

Flamegraphing your way out of "this can't possibly be right"

“Comments lie. Flamegraphs don't.”

When 18 nodes pegged my 80-core box at 100%

“Three obvious wins got the host from 100% to 35%. Still wrong, just less wrong.”

Why I'm building a distributed mesh substrate in Rust

“I want to feel where the iroh-as-substrate story breaks at small scale before betting a real product on it.”
