0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364Stored on Base mainnet · chainId 8453
This record lives on the ProteanLedger UUPS proxy at 0x2a6f84fA…a4a364. The chain is the source of truth — the explorer is a read-only lens.
Four commands. Two terminals. No login. No wallet. No trust in Protean Labs required.
1. Read the record from chain
cast call 0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364 \ "getRecord(bytes32)" \ 0xa7858230ccb9556d7dbd472044bbb0f2a73ecd632a342cb3e9fc824b6a20c564 \ --rpc-url https://mainnet.base.org
2. Inspect via the indexer JSON API
curl -s https://www.protean.sh/ledger/api/v1/records/0xa7858230ccb9556d7dbd472044bbb0f2a73ecd632a342cb3e9fc824b6a20c564 | jq
3. Reproduce the canonical state digest from genesis
curl -sL https://raw.githubusercontent.com/proteanlabs1/ledger-mirror/main/scripts/index_ledger_from_genesis.py -o index.py python3 index.py --rpc https://mainnet.base.org \ --proxy 0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364 \ --db /tmp/protean.db --from-block 46612390 --once python3 index.py --digest-only --db /tmp/protean.db # Compare against https://www.protean.sh/ledger/api/v1/indexer/digest
4. Confirm published indexer digest
curl -s https://www.protean.sh/ledger/api/v1/indexer/digest | jq '.digest, .record_count, .last_block'
Verification
What we can attest to from indexer state. Replay-artifact + content-digest verification you run yourself — see the verify page for copy-pasteable shell snippets and the public mirror for the canonical reproducibility script.
Top-ranked peptide candidate from runtime cycle cognition-45-1780070966. Generation method: deterministic_constraint_recombination. Confidence: medium. Sequence and salted commitment withheld; recovering the sequence from the on-chain content digest is unfeasible. Wet-lab assay validation is the authoritative downstream layer.
First-class on-chain edges. Every relation has a typed RelationType and a corresponding event log entry. Click any neighbor to navigate.
Descendants (0)
No on-chain descendants yet. This record is the most recent in its lineage.
This record uses a legacy placeholder replay pointer from before mirror artifact hashing was fully wired into the approved Ledger write path. The artifact at the cited mirror path is real and reachable, but its sha256 was authored after the Ledger write (the chain pointer carries a 'pending' placeholder rather than the artifact's actual sha256). Chain identity, content digest, lineage, and indexer digest reproduction all still verify; the artifact-sha256-equality check that 'mirror_real' records support is not available for this class. Fetch the artifact from the mirror to confirm the file exists and matches the on-chain record content fields.
