Verify this record yourself

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)" \
  0x0fb7b323d4cdec3bdb571752fa332069e17a1a5ea0df2d7dc037ff7acd005427 \
  --rpc-url https://mainnet.base.org

2. Inspect via the indexer JSON API

curl -s https://www.protean.sh/ledger/api/v1/records/0x0fb7b323d4cdec3bdb571752fa332069e17a1a5ea0df2d7dc037ff7acd005427 | 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 \

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.

Summary

Operational milestone: indexer published, explorer wiring committed, Bankr destination allow-list updated to include the Ledger proxy. Marks the transition from deployment to activation. No scientific claim.

Historical Bootstrap Record

Artifact mirror was introduced after this record was registered. Chain identity, content digest, lineage, and indexer reproduction verification all remain available. Public artifact sha256 verification was not available at registration time; the mirror carries an honest reconstruction in artifacts/mainnet/ with documented limitations.
