Why can my wallet not verify whether the RPC node it trusted told the truth?
機会
Almost every dApp and wallet routes its blockchain queries through Infura, Alchemy, or a comparable centralized provider. Those providers can return manipulated state, censor transactions, or go offline with no cryptographic consequence for the user. Light clients can check Merkle proofs for specific values but must bootstrap from a trusted header and rely on peers for data availability. A paper accepted at IEEE ICDCS 2025 identifies the core impasse: permissionless public RPC endpoints have no accountability, while registered providers have accountability but require permissioned access, and no financial incentive exists for altruistic full non-validating nodes to serve read traffic at scale. No production system combines cryptographic verifiability, open participation, and sustainable incentives in a single protocol.
重要な理由
If the RPC layer can lie without consequence, a user has no guarantee that the chain state they read is real or that their signed transaction was broadcast honestly.

Opportunity Scoreは測定値ではなく、私自身の見解です。どれほど痛みを伴うか、どれほど頻繁に影響を与えるか、そして今日時点で解決策がいかに少ないか。スコアが高いほど、構築する価値が高いと私は考えています。
それが現れたときにどれほどの痛みをもたらすか。
実際にどれほど頻繁に人々がそれに直面するか。
今日時点で、それに対する優れたツールがいかに少ないか。
