# Beacon(eth2) based blockchain development
Utils for the managements of local and distributed beacon clusters.
Assume your project id(name) is `$PROJECT`,
the `dev` meta path will be:
- `/__chain_dev__/beacon_based/${PROJECT}/${HOST}/${USER}/__dev__`
the `ddev` meta path will be:
- `/__chain_dev__/beacon_based/${PROJECT}/${HOST}/${USER}/__d_dev__`
If the `$PROJECT` is not set(empty value),
the `dev` meta path will be:
- `/__chain_dev__/beacon_based/${HOST}/${USER}/__dev__`
the `ddev` meta path will be:
- `/__chain_dev__/beacon_based/${HOST}/${USER}/__d_dev__`
