The Future of Censorship Resistance Lies in P2P Protocols

Federated bridges rely on a small set of oracles for state verification, creating a single point of failure and censorship. A 51% attack on the signer set can steal funds or freeze assets.\n- Attack Surface: ~$2B+ lost to bridge hacks, primarily via oracle compromise.\n- Censorship Vector: Relayers can be forced to blacklist addresses, breaking neutrality.

Capital is concentrated in a handful of centralized bridge contracts, making them fat targets. Withdrawal limits and liquidity fragmentation create poor user experience and systemic risk.\n- Capital Inefficiency: Locked TVL earns no yield and is idle between transfers.\n- Fragmented UX: Users must hunt for liquidity across Wormhole, LayerZero, Axelar, etc.

Incorporated relayers and foundation-run multisigs are subject to jurisdictional pressure. OFAC sanctions compliance is trivial to enforce, turning infrastructure into a regulatory weapon.\n- Protocol Neutrality Lost: Services like Tornado Cash sanctions demonstrated this risk.\n- Single Jurisdiction: A court order can freeze assets across the entire network.

Protocols like Electron and Succinct enable trust-minimized bridging by verifying chain headers directly. No intermediary signs or holds funds.\n- Trust Assumption: Security reduces to the underlying L1 (e.g., Ethereum).\n- Censorship Resistance: Validation is permissionless; no entity to pressure.

Users submit a desired outcome (intent), and a decentralized network of solvers competes to fulfill it atomically across chains. Removes the need for centralized liquidity pools.\n- Capital Efficiency: Solvers tap into existing DEX liquidity (Uniswap, Curve).\n- Best Execution: Competition among solvers minimizes cost and maximizes output.

A fully connected graph of P2P validation nodes, inspired by Bitcoin's and Nakamoto consensus. Each node acts as its own light client verifier, creating a resilient, leaderless network.\n- No Single Points: Failure or censorship of any node does not affect the network.\n- Incentive Alignment: Nodes earn fees for proof relay, not for custody.

A malicious node isolates a target by monopolizing all its peer connections, creating a false view of the network. This enables double-spends and censorship.

• Vulnerability: Requires controlling a victim's ~8-10 peer slots.
• Real-World Risk: High for lightweight clients and nodes with poor bootstrapping.

Adversaries create many fake identities (Sybils) to gain disproportionate influence, then combine it with network-layer attacks like BGP hijacking or DDoS.

• Amplifies Censorship: Can partition the network or target specific validators.
• Historical Precedent: Ethereum's 2020 Geth bug led to accidental chain splits, showcasing network fragility.

P2P layers for block propagation are mature, but guaranteeing data availability for rollups is a separate, harder problem. Light nodes cannot independently verify if all transaction data is published.

• Current Reliance: Most L2s trust a centralized sequencer or a small DA committee.
• Emerging Solution: Projects like Celestia and EigenDA are building P2P DA networks, but adoption is early.

Running a full P2P node is a public good with high cost and no direct reward. This leads to centralization around subsidized infrastructure providers like Infura and Alchemy.

• Centralization Pressure: >60% of Ethereum traffic routes through a few centralized RPCs.
• Solution Path: Protocols like Ethereum's PBS and peer-to-peer MEV networks attempt to realign incentives.

As P2P networks grow, upgrading core protocols (e.g., Ethereum's Devp2p) becomes politically and technically fraught. Hard forks are risky, creating stagnation.

• Consequence: Innovation shifts to application layer, leaving base layer vulnerable to newer, more efficient attacks.
• Example: Bitcoin's slow adoption of P2P encryption (Dandelion++) illustrates the challenge.

All decentralized logic runs on centralized hardware (AWS, Google Cloud) and physical internet infrastructure. A state-level actor can always disrupt the network at this layer.

• Unavoidable Risk: BGP hijacks and undersea cable cuts are existential threats.
• Mitigation: True resilience requires mesh networks and satellite-based block propagation, which are nascent.

95%+ of dApp traffic flows through a handful of centralized RPC providers like Infura and Alchemy. This creates a single point of failure for censorship and MEV extraction.\n- Vulnerability: A state-level actor can blacklist addresses at the RPC layer.\n- MEV Leakage: Your users' transaction intents are visible before hitting the public mempool.

Shift validation to the client side using light client protocols (e.g., Helios, Succinct) and peer-to-peer networking stacks like libp2p. This removes trusted intermediaries for data retrieval.\n- Direct Access: Clients sync chain headers and fetch proofs directly from full nodes.\n- Network Resilience: A global mesh of peers is orders of magnitude harder to censor than a few API endpoints.

Rollups have re-centralized transaction ordering. Dominant sequencers (e.g., Arbitrum, Optimism) can front-run, censor, and extract MEV. Their centralized hardware is a liveness risk.\n- Economic Risk: A single sequencer failure halts the chain.\n- Trust Assumption: Users must trust the sequencer's output is correct.

Decentralize the sequencer role via permissionless networks like Espresso, Astria, or shared sequencer layers. This uses Tendermint-like consensus for ordering.\n- Censorship Resistance: No single entity controls the inbox.\n- Interoperability: Enforces atomic cross-rollup composability, a killer app for the modular stack.

Celestia and EigenDA are becoming new centralization points. While decentralized in theory, early staking and hardware requirements lead to validator concentration. The data layer must be maximally credibly neutral.\n- Cost Leverage: A dominant DA layer can price-gouge rollups.\n- Cartel Risk: Large stakers can collude to withhold data.

Incentivize a global peer-to-peer network for data storage and retrieval, moving beyond a small set of bonded validators. Think BitTorrent with crypto-economic guarantees.\n- Radical Redundancy: Data is replicated across thousands of untrusted nodes.\n- Client-Enforced Security: Light clients use data availability sampling to probabilistically verify data is published.
