Metering Chain Phase 3: Capability-Driven Delegation
In DePIN, owners can't sign every event, and letting operators submit usage without proof opens a trust hole. Phase 3 adds delegation: the owner issues a sig...
Metering Chain Phase 2: Deterministic Authorization for Multi-Operator DePIN
In the first post, Metering Chain showed that usage can be replayed into deterministic balances: same history, same bill. That part worked. What kept nagging...
Ethereum Account State: A Minimal Token with Reconstructible State
I built this project to answer a simple question: can you reconstruct a token's entire state just from events, without ever reading storage?
Metering Chain: Deterministic Billing
I started working on Metering Chain after yet another “we have the logs, but the bill still feels wrong” incident in a usage-based system. On paper, everyone...
Learning Consensus Algorithms: A Hands-On Comparison with Rust
I conceptually implemented five consensus algorithms in Rust to compare PBFT, Gossip, Eventual Consistency, Quorum-less, and Flexible Paxos. The project is r...
