Launches Verifiable Work Layer for AI**  \n\n*SAN FRANCISCO, Oct 14 2026* – Zambo today releases a production‑grade “verifiable work” layer that records every AI‑generated byte, timestamps it, and stores an immutable receipt. The service goes live immediately, giving developers a tamper‑evident proof that saved data has not been altered—without claiming correctness of the content. Receipt example: https://zambo.dev/run/91905673-bd41-4274-87c9-07ce064eebd6.  \n\nThe new layer plugs into existing AI pipelines, generating a cryptographic hash for each output file and appending it to a public ledger. Developers can query the ledger to confirm that a byte‑string matches the original receipt, ensuring audit trails survive storage migrations and cloud‑provider changes. Market context underscores demand for trustworthy AI: Bitcoin trades at $81,736 USD (▼1.72 % 24 h) 【CoinGecko】 Receipt https://zambo.dev/run/91905673-bd41-4274-87c9-07ce064eebd6; Ethereum at $2,429 USD (▼3.01 %); Solana at $104 USD (▼3.01 %).  \n\nZambo’s platform also integrates ProvibeCode’s read‑only audit tool and Signal’s professional trust passport, enabling multi‑agent research workflows. A typical run—running three large language models in adversarial debate, then synthesizing the consensus—produces a “research receipt” that timestamps the process and its findings (see https://zambo.dev/run/465a110d-e454-41cb-95f8-aab585a0ee85). This capability helps teams certify insights before public release.  \n\n“Providing an immutable record of AI work removes the guesswork from compliance and quality assurance,” said **Dr. Maya Patel, Chief Technology Officer, Zambo**. “Our receipt system proves that data remains exactly as saved, letting engineers focus on what matters—building better models.”  \n\n**About","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:bc1795f50cd55478eda814d1868a40e91920952eae875dff5bc4fb908f7cf340","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:c7e2cfe14716a8558f089cef54655e93d50431161a188d06718d4b349409a3d6","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:82890e25ca34d68c29995119a74dc935818620881b1d10fa94c6f1825d3be0a8","anchor":{"event_id":"8b3d3c9566b9d766e780b3c150f5e9d3dfb2a9d6cecb935d1feb6d56abaf7f4d","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-14T19:55:18.227Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-14T19:55:17.315Z","evidence_url":null,"receipt_uuid":"250bc969-0cac-4c04-ac7b-02e7285de019","output_sha256":"sha256:3c9169f29ce805eb9d82052278a12dd5cb1231fa8aeb132c9182ade2631586b9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-14T19:55:17.315Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3c9169f29ce805eb9d82052278a12dd5cb1231fa8aeb132c9182ade2631586b9\",\"receipt_uuid\":\"250bc969-0cac-4c04-ac7b-02e7285de019\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-14T19:55:17.315Z","detail":"The receipt store reports 2026-10-14T19:55:17.315Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
