# IPFS as a remote log

Checking basic feasability and flow.

```
# Remote log over IPFS and IPNS
# Basic feasibility check

# 0. Run `ipfs daemon` in background

# 1. Upload first message to CAS
> cat foo
1 hello
> cat foo | ipfs add

## Notes

- Pin locally
- Pinning services for altruistic mode?
- Diff interface from Swarm Feeds with topic subspace vs new key for each
- Perf of name updated?
- Check resolution from other host
