Why Adversarial Coordination Is Inevitable in Open Systems

An examination of the fundamental economic and game-theoretic forces that make adversarial coordination a guaranteed outcome in permissionless networks, with a focus on public goods funding mechanisms like quadratic voting and retroactive grants.

introduction
THE COORDINATION PROBLEM

The Inevitable Adversary

Open, permissionless blockchains structurally incentivize adversarial coordination, making it a feature, not a bug.

Adversarial coordination is inevitable because blockchains are open, global state machines. Any actor can observe pending transactions and assemble a competing bundle for profit, a dynamic formalized in Maximal Extractable Value (MEV) research.

This coordination is economically rational, not malicious. Entities like Flashbots and Jito Labs exist to optimize this process, creating private orderflow channels and efficient block building that centralizes around profit.

The counter-intuitive insight is that suppressing this force creates worse outcomes. Attempts to hide transaction intent, as with Taichi Network or encrypted mempools, simply shift coordination to more opaque, less accountable venues.

Evidence: Over 90% of Ethereum and Solana blocks are built by professional searcher-builder networks. This proves coordination is the equilibrium state in systems where value is transparent and execution is competitive.

THE GAME THEORY

First Principles: Why Coordination Is Guaranteed

Open financial systems create predictable profit opportunities that rational actors will inevitably exploit.

Profit-seeking is rational. In a permissionless system, any actor with capital will execute strategies that guarantee positive returns. This is not malfeasance; it is the Nash equilibrium of an open, transparent ledger.

Coordination is a force multiplier. Individual arbitrage is limited. Adversarial coordination between searchers, builders, and validators (e.g., via MEV-Boost or private mempools) captures exponentially more value, as seen in Ethereum block construction.

Infrastructure enables cartels. Tools like Flashbots' SUAVE or shared orderflow auctions don't just facilitate coordination; they institutionalize it, creating persistent, optimized networks that outcompete isolated actors.

Evidence: Over 90% of Ethereum blocks are built by a coordinated cartel of builders and relays, proving that adversarial coordination is the system's dominant, stable state.

Coordination Inevitability Thesis

Collusion is structurally simple for a small, known set.

Staking yields and MEV profits create natural pressure towards centralization in pools/relays.

Profit maximization inevitably pools hashpower; seen with Foundry, Antpool >55% combined.

Real-World Manifestation

Consortium deadlock or fork.

Proposer-Builder-Separation (PBS) creating builder cartels.

Mining pool consolidation leading to repeated >51% thresholds.

System's Response

Off-chain legal arbitration.

In-protocol slashing & social consensus (fork choice).

Neutral protocol rules; defense is miner exit to other pools.

THE INEVITABILITY THESIS

The Futility of Naive Defense

Adversarial coordination is a thermodynamic law for open systems, not a bug to be patched.

Adversarial coordination is inevitable. Permissionless systems like Ethereum or Solana create a public state machine. Any actor can read the state, compute a profitable strategy, and execute it. This creates a permanent, automated incentive for attackers to form coalitions, as seen in MEV extraction via Flashbots.

Static defense is a losing game. Hard-coded rules in protocols like Uniswap V2 are predictable. Attackers optimize around fixed parameters, leading to exploits like sandwich attacks. This creates a reactive cycle where protocols like Aave must constantly patch after losses.

The attacker's advantage is structural. Defenders must secure all vectors; an attacker needs one. This asymmetry makes total security impossible. Projects like OlympusDAO learned this when their treasury bonding mechanics were gamed for predictable profits.

Evidence: Over $3 billion was extracted via MEV in 2023 (Flashbots data), proving adversarial coordination is the dominant economic force, not an edge case.

FREQUENTLY ASKED QUESTIONS

Frequently Contested Questions

Common questions about the inevitability of adversarial coordination in open blockchain systems.

Adversarial coordination is when independent actors collude to exploit a system's rules for profit, a fundamental feature of permissionless blockchains. Unlike a single hacker, it involves groups like MEV searchers forming cartels to front-run trades or validators in a Proof-of-Stake network like Ethereum colluding to censor transactions. This behavior is not a bug but an emergent property of open, incentive-driven systems.

takeaways
WHY ADVERSARIAL COORDINATION IS INEVITABLE

Architectural Imperatives

Open, permissionless systems cannot rely on trusted third parties, forcing them to architect for adversarial participation from first principles.

01

The Byzantine Generals Problem Is Your Foundation

Distributed consensus is the core challenge of open systems, where participants may be faulty or malicious. Protocols like Bitcoin's Nakamoto Consensus and Ethereum's LMD-GHOST are solutions that make coordination under adversarial conditions possible.\n- Key Benefit: Achieves state agreement without a central authority.\n- Key Benefit: Tolerates up to 1/3 to 1/2 of participants acting maliciously, depending on the model.

MEV: The Market for Block Space Is Adversarial

Maximal Extractable Value is not a bug; it's an emergent property of transparent mempools and decentralized block production. It creates a coordination game between searchers, builders, and validators, formalized by systems like Flashbots' SUAVE.\n- Key Benefit: Transforms chaotic front-running into a credibly neutral auction.\n- Key Benefit: Protocols like CowSwap and UniswapX use intents to shield users from this adversarial landscape.

Bridges Must Assume All Chains Are Hostile

Cross-chain communication layers like LayerZero, Axelar, and Wormhole operate in a zero-trust environment. They cannot rely on the security of any single chain and must architect for the failure or censorship of connected domains.\n- Key Benefit: Economic security via bonded relayers or optimistic verification.\n- Key Benefit: Liveness guarantees through decentralized oracle networks and fallback mechanisms.

Decentralized Sequencers Are a Coordination Game

Rollups initially centralize sequencing for efficiency, but decentralization reintroduces the adversarial coordination problem. Solutions like shared sequencer networks (e.g., Espresso, Astria) and based sequencing compete to order transactions without trust.\n- Key Benefit: Censorship resistance via permissionless block building.\n- Key Benefit: Interoperability through atomic cross-rollup composability.

DA Layers: Data Availability Is a Consensus Problem

Scaling requires separating execution from data availability, creating a new adversarial frontier. Celestia, EigenDA, and Avail provide secure DA by ensuring data is published and available for fraud proofs, a problem reducible to sampling and erasure coding.\n- Key Benefit: Scalability via ~MB/s data throughput.\n- Key Benefit: Cost reduction by ~100x versus calldata on L1.

The Oracle Problem: Trusting the Outside World

Smart contracts are blind. Bringing in external data (price feeds, randomness) via Chainlink, Pyth, or API3 requires creating a decentralized system that is resilient to data manipulation and provider downtime.\n- Key Benefit: High-frequency updates with ~400ms latency.\n- Key Benefit: Cryptographic proofs (e.g., zk-proofs from RedStone) for verifiable data.
