“应用”在 Arc 上意味着什么
属于应用而非交易基础设施。ERC-8004 代理注册表被放在这里而不是预言机之下：它们高频的 NewFeedback 事件承载的是关于软件代理的声誉分数而不是价格，解码后的载荷可以证明这一点。每一行都带有识别它所依据的测量。

| 0x8004A818...9A494BD9e | ERC-8004：身份注册表 | — | Its EIP-1967 implementation 0x7274e874...9c02 carries the literal `ERC8004IdentityRegistry` in deployed bytecode, read at block 54,290,008 — the standard names itself. Corroborated by the event stream: emitted 566 Registered(uint256,string,address) and 568 MetadataSet(uint256,string,string,bytes) events in 53,963,591-54,259,161; both signatures were recovered by matching keccak preimages against the observed topic0s (0xca52e62c...bc4a and 0x2c149ed5...468b) and match exactly. Also mints an ERC-721 per registration and emits EIP-4906 MetadataUpdate. On every one of the 568 MetadataSet events the indexed topic equals keccak of the readable key carried in the payload, so the key is verified rather than assumed. 505 of its registrations publish a base64 data-URI agent card, and those cards embed the literal URL https://eips.ethereum.org/EIPS/eip-8004#registration-v1. 0x8004-prefixed vanity address, alongside the reputation registry 0x8004b663...8713 and the validation registry 0x8004cb1b...4272.字节码字符串 · 测量于区块 54,290,008 | 54,290,008 | — |

| 0x8004B663...3B7388713 | ERC-8004：声誉注册表（代理） | — | Busiest of the two emitters of the chain's THIRD-busiest event, 278,675 of 476,450 logs on topic0 0x6a4a6174... in blocks > 54,080,000. An EIP-1967 minimal proxy (storage slot 0x360894a1... holds 0x16e0fa7f...da34). NOT a price oracle: the implementation's bytecode carries `Self-feedback not allowed`, `bad identity`, `clientAddresses required`, and the event's own data payload decodes to the ASCII string `successful_execution` plus three empty strings — an attestation record, not a price. The standard is named from cryptographic proof rather than resemblance: keccak of `NewFeedback(uint256,address,uint64,int128,uint8,string,string,string,string,string,bytes32)` is exactly the observed topic0 0x6a4a6174...febc, recovered by brute-forcing preimages. It sits at a 0x8004-prefixed vanity address alongside the identity registry 0x8004a818...bd9e and the validation registry 0x8004cb1b...4272, and the agent cards published through that identity registry embed the literal URL https://eips.ethereum.org/EIPS/eip-8004#registration-v1. It indexes agentId, clientAddress and tag1, so its third topic is keccak(tag1) rather than the feedback counter — verified on 464,153 of 464,153 events.字节码字符串 · 测量于区块 54,281,486 | 54,281,486 | — |
| 0x4C80b778...e49AE9FFE | ERC-8004：声誉注册表（第二次部署） | — | Second emitter of the same feedback event, 197,775 logs in blocks > 54,080,000. A standalone 13,188-byte deployment (no proxy) whose bytecode carries `Feedback not found`, `Already revoked`, `IdentityRegistry not set`. Emits nothing else. This emitter carries the decisive evidence against reading the event as a price feed: its 736-byte payload is a percent-encoded data URI that decodes to `{"d":"trading/futures Score:88","s":88,"e":"cex:bybit","ts":"2026-07-29T16:28:05.861Z"}` — a subject, an integer score, an issuing entity and a timestamp. Sampled payloads score `trading/spot` from `cex:binance` and `risk/simulation` from `security:tenderly`. There is no price, no pair and no decimals anywhere in it — the score's scale is a uint8 in the event itself, and score/10**decimals equals the number stated in that JSON on 781,125 of 781,125 events carrying one. The standard is named from cryptographic proof rather than resemblance: keccak of `NewFeedback(uint256,address,uint64,int128,uint8,string,string,string,string,string,bytes32)` is exactly the observed topic0 0x6a4a6174...febc, recovered by brute-forcing preimages. This deployment indexes the uint64 feedback counter where the other indexes tag1, so the same topic0 carries two incompatible payload layouts.字节码字符串 · 测量于区块 54,281,486 | 54,281,486 | — |
| 0x8004Cb1B...7acEB4272 | ERC-8004：验证注册表 | — | Sole emitter of ValidationRequest(address,uint256,string,bytes32) (42 events) and ValidationResponse(address,uint256,bytes32,uint8,string,bytes32,string) (18 events) in 53,962,678-54,278,830. Both signatures were recovered by keccak preimage search against the observed topic0s 0x530436c3...5059 and 0xafddf629...49ae and match exactly. Request and response share a bytes32 request hash in their third topic, and the agent ids they name are the same ids the reputation registry at 0x8004b663...8713 scores. Rare by design rather than by disuse: 60 events against that registry's 464,155. Its EIP-1967 implementation 0xdb31f5d9...7f99 carries no naming string — only the revert `bad identity`, which the reputation registry's implementation also carries — so this row rests on the two signatures, the shared 0x8004 vanity prefix and the shared agent ids, not on a name the contract gives itself. It is the weakest of the ERC-8004 rows and is marked as such.事件签名 · 测量于区块 54,290,008 | 54,290,008 | — |

Sole emitter of 7,383 logs on each of two topics in blocks > 54,080,000, in a chain whose event registry already carries NameRegistered and PrimaryNameSet — consistent with a naming service, but only its own metadata names it.合约自述 · 测量于区块 54,281,486 | 54,281,486 | — |
