# 7. External resources: search, storage, and the chain
|
||
|
||
| Resource | Where | How a Zap reaches it |
|
||
|----------|--------|----------------------|
|
||
| **Central chain** (itemized SHA-256 + time + certificate) | `api.veraetime.net` or MOCK | HTTPS via middleware: create / wait / `GET /hashes/{sha256}` |
|
||
| **Bulk Merkle root** | Same chain, one seal | `POST /timestamp/batch` |
|
||
| **Leaf proofs** (hash only in a bulk summary) | Tree-node WORM on NATS | `GET /hashes/{sha}?includeTree=true` → `verae.archive.query` kinds=`tree` |
|
||
| **Public / private metadata, files** | WORM archives | `includeAttached`; never on chain |
|
||
| **Search (central)** | Chain lookup | Zapier search **Find Timestamp by SHA256** |
|
||
| **Search (external tree / extra stores)** | NATS query to every node that might hold the key | Zapier search **Find Hash (tree nodes + central)** |
|
||
| **Future search / store** | New `verae.search.*` or `verae.store.*` process | Copy `verae-nats-process`; optional middleware GET |
|
||
|
||
Storage that is **not** the blockchain stays on WORM/tree nodes (and later any process that answers `verae.archive.query` or a new store address). The chain stores hash + time + certificate (+ Merkle root for batches).
|
||
|
||
External “unplanned” storage or search is the same pattern: new address, bloom or index on that node, silence on miss, aggregator or the template’s reply subject.
