Content Identifiers (CIDs) are cryptographic hashes that uniquely identify content in IPFS.

## CID Resolution
|
|
|
|
|
|
|
|
|
|
### Resolution Process
|
|
|
|
|
1. Query local IPFS node cache
|
|
|
|
|
2. Search connected peers
|
|
|
|
|
3. Fetch from distributed network
|
|
|
|
|
4. Return raw content data
|
|
|
|
|
|
|
|
|
|
### CID Formats
|
|
|
|
|
- **CIDv0**: Legacy format (starts with 'Qm')
|
|
|
|
|
- **CIDv1**: Modern format (starts with 'bafy')
|
|
|
|
|
|
|
|
|
|
Example CIDs:
|
|
|
|
|
```
|
|
|
|
|
CIDv0: QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG
|
|
|
|
|
CIDv1: bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi
|
|
|
|
|
```
|

Pin frequently accessed content to your local IPFS node for faster retrieval.

### Caching Strategy
|
|
|
|
|
- Hot data: Keep pinned locally
|
|
|
|
|
- Warm data: Cache with TTL
|
|
|
|
|
- Cold data: Fetch on demand

:::warning
|
|
|
|
|
Large files may take time to retrieve if not cached locally or on nearby peers.

## Error Handling
|
|
|
|
|
|
|
|
|
|
Common errors:
|
|
|
|
|
- **404**: CID not found in network
|
|
|
|
|
- **408**: Timeout fetching content
|
|
|
|
|
- **507**: Local storage full
|
