One-round confirmation (speculative finality) in MonadBFT is only honest if equivocation is economically self-defeating. If a client can act after a single QC (Quorum Certificate), then any attempt to sign two conflicting histories must be so expensive that no rational validator tries. That’s a mechanism-design statement, not just a protocol cla...

Overview Consensus protocols live inside economies. Validators carry stake, pay operating costs, chase or defend against MEV, and sometimes collude. If we describe MonadBFT as only a message-passing algorithm, we miss the forces that drive real outcomes. In this series we treat MonadBFT as a mechanism: a rule system played by strategic agents. O...

Overview This is a short presentation that explains the journey of a message using LayerZero’s cross-chain messaging protocol. It’s structured like a presentation with accompanying notes. Learning Intentions & Success Criteria Learning Intentions Understand how LayerZero V2 moves a message across chains—securely and reliably Trace th...

The CORE Pipeline In Part 1 we showed why a forged cross-chain message is unprofitable when the cost of corruption (stake at risk, reputation at risk, and chance of being caught) dominates the value at risk. Part 2 turns that idea into a working system that a protocol can run on a schedule: it sets stakes, fees, and watcher bounties; it proves ...

A practical deep dive into game theory, correlation, and mechanism design for LayerZero (split), CCIP (quorums), and Across (optimistic) Most bridges don’t fail because the cryptography breaks—they fail because the economics make cheating profitable for a small, correlated group at the same time. If we want to reason clearly about LayerZero’s s...

Introduction In my previous article on game-theoretic vulnerabilities in shMONAD bandwidth allocation, I showed how bandwidth staking can create a high-stakes, non-cooperative congestion game where strategic timing (e.g., flash-commit bursts) distorts access to RPC throughput. This follow-up blog on Monad looks at a different chokepoint—price d...

Overview Maximal Extractable Value (MEV) isn’t inherently bad; the way it’s competed for is. When extractors rush, spam, and reorder to capture value, they impose costs on everyone else, worse prices for takers, adverse selection for LPs, congestion and failed transactions for bystanders, and a latency arms race that wastes real resources. A Pi...

Abstract Blockchain transaction fee markets have long been plagued by volatile fees, rampant overpayment, and under-utilized block capacity. Legacy first-price auctions force users into a painful guessing game, while EIP-1559’s base-fee mechanism, though an improvement, introduces algorithmic oscillations and is vulnerable to miner exploits.
