moth: independent verification

1. read the root

fetch the root through an archival solana mainnet rpc with maxSupportedTransactionVersion set to 1. check finalization, transaction success, publisher and the spl noop program. the root records the source revision, package length, sha-256 hash and index references.

2. reconstruct the package

follow the two index levels in order. read every data transaction, reject duplicate signatures or inconsistent chunk numbers, and concatenate its payload. the verifier checks the signer, record type, package identifier, expected size and successful execution.

3. check every file

compare the compressed package sha-256 with the root, decompress it and parse the embedded manifest. verify file sizes and hashes; reject unsafe paths, overlapping offsets, missing data and trailing bytes.

these are the 18 effective recovered files, including the root-pinned player correction. checking downloads about 148 MB and hashes each file on your device.

check served file hashes

not checked in this browser session.

this compares our served files with our published report. it is not a fresh blockchain verification. use the independent verifier below to reconstruct from your own archival rpc.

4. verify independently

download verifier source

extract the kit in a fresh directory. use node.js 22.13 or later, run npm install, then copy .moth-private/config.example.json to .moth-private/config.json and set your own archival mainnet rpc. no wallet or private key is needed. the kit includes the source and full instructions.

the root also references a corrected player page. the verifier checks that transaction and its hash separately, preserves the original bundled page, and installs the verified correction as index.html.

player correction transaction · original archived player

browser compatibility note: the archived player can automatically select an absent asyncify runtime on webgpu devices. our site launcher explicitly selects the included jsep wasm pair and cpu inference. it is a site-only adapter, not an onchain correction. all 18 recovered files remain byte-for-byte unchanged.

5. what this proves

matching hashes establish that the recovered files match the selected root. they do not prove model accuracy, original training, or inference performed by solana validators. the model is stored in transaction history; inference happens on the device running it.

an archival provider or a verified mirror is needed if a node no longer retains this history. the browser player opens our recovered local copy; it does not itself download and verify every transaction. the downloadable verifier and report are site-provided tools and evidence, not additional onchain records.
