a.k.a. “Private Chain 0” → parameters-carthage-pc0.json
It's compatible with the tutobox, and can use the
--override-protocol-parameters options:
docker run --rm --name my-sandbox --detach -p 20000:20000 \
-v $PWD:/pwd/ \
registry.gitlab.com/tezos/flextesa:image-tutobox-run carthagebox start \
--override-protocol-parameters /pwd/parameters-carthage-pc0.json
Verify it worked:
$ tezos-client rpc get /chains/main/blocks/head/context/constants

Tweaked constants:
- Time between blocks: 10s.
- Double both gas limits.
- Double storage limit per operation.
- 10 000 ꜩ / roll.
- For counting with round numbers, “10 grand = 1 roll” ☺.
- Smaller rolls Vs initial balances make protocol activation a bit more CPU/disk intensive (roll distribution).
- michelson maximum type size × 5
- Tiny security deposits 1 ꜩ/block, 0.1 ꜩ/endorsement
- Staking; preserved-cycles + blocks-per-cycle are tiny (sandbox levels), so a new registered baker gets baking rights within minutes (about 7 in my one experiment).
