Launches Verifiable Work Layer for AI, Delivering Immutable Byte‑Saving Receipts**  \n\n*NEW YORK, Oct 14 2026* – Zambo, the emerging platform that records AI‑generated work as tamper‑proof evidence, today released its first production feature: a receipt that proves the number of bytes saved by an AI task remains unchanged from execution to verification. The service goes live worldwide, with real‑time crypto market data displayed alongside each receipt to illustrate the economic context of AI‑driven efficiency.\n\nThe rollout coincides with live price feeds from CoinGecko for Bitcoin (BTC $81,758 ▼ 1.72 % / $1.64 T market cap), Ethereum (ETH $2,432.63 ▼ 3.04 % / $297.15 B) and Solana (SOL $104.54 ▼ 3.00 % / $61.61 B), all captured at 19:29:45 GMT on Oct 14. Each receipt, such as the Bitcoin‑linked proof <https://zambo.dev/run/8f021309-f75c-4059-ab72-43a58ea17246>, shows the exact byte count before and after optimization, confirming that the reduction is genuine and immutable, though it does not assert the correctness of the underlying AI output.\n\nZambo’s verification engine integrates existing tools like ProvibeCode’s audit teaser and Signal’s trust passport, delivering a unified “research‑to‑launch” workflow. Users can trigger a read‑only audit of public repositories, receive a Provibe Score, and instantly generate a certified receipt that can be published or shared with stakeholders. The platform’s universal score of 62 (research branch, medium impact) indicates a rapid 15‑minute implementation path for teams seeking transparent AI accountability.\n\n“Providing an auditable, byte‑level receipt eliminates the guesswork around AI efficiency claims,” said **Aisha Patel, Chief Product Officer of Zambo**. “Our users now have a single source of truth that bridges technical validation and business impact.”\n\n**About Zambo**  \nZambo builds the verifiable work layer for artificial intelligence, enabling developers, enterprises, and researchers to certify AI‑generated outputs with immutable proofs. By anchoring byte‑level metrics to blockchain‑grade receipts, Zambo drives trust, reproducibility, and measurable ROI across the AI ecosystem.\n\n**Media Contact**  \nJordan Lee, Director of Communications  \nemail: [REDACTED_EMAIL]  \nphone: +1 212‑555‑0198","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:71fddfe7f99c1713e1668c1343f59da7af52fa48713f1e56a962e2b01a7c7e6c","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:b52df08e3637a308b7b45d3d76ecc258ed72c67d2a023abafcc10b648480d20a","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:e89cc4efa8b7f20b5a8456829a5e74e331014a48e1ab7e659d26686b48e067df","anchor":{"event_id":"73d08d752760edaf6bb2ee2763e528da6e62f5346f36066cc1a37f882bacab94","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-14T19:29:53.294Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-14T19:29:52.735Z","evidence_url":null,"receipt_uuid":"efd2f511-d741-4ed6-a5e5-b55f4a6665b2","output_sha256":"sha256:a067ea611598f39eed2c6f35502f45fe6e9421015fde4de5aac3be75e62a5dd9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-14T19:29:52.735Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:a067ea611598f39eed2c6f35502f45fe6e9421015fde4de5aac3be75e62a5dd9\",\"receipt_uuid\":\"efd2f511-d741-4ed6-a5e5-b55f4a6665b2\",\"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":"2026-10-14T19:29:52.735Z","detail":"The receipt store reports 2026-10-14T19:29:52.735Z; 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.
