etc. With notary service, it takes up to seven times fewer transactions
to do these operations. Notary service calculates the exact amount of GAS
to execute transaction, therefore operations are cheaper (withdraw fee **with**
notary is less than 0.5 GAS; withdraw fee **without** notary is up to 7.0 GAS).
notary is less than 0.5 GAS; withdraw fee **without** notary is up to 7.0 GAS).
By default, main chain service is running without notary service, and side chain
running with notary service. However, you can change that in configuration.
Currently, frostfs-dev-env contains single chain (see morph service) and it
enables notary service from the genesis block.
# Disable notary service in side chain
To disable notary service in side chain do these steps.
1. Update `.env` and choose notary disabled chain dump for side chain.
```
MORPH_CHAIN_URL="https://github.com/nspcc-dev/neofs-contract/releases/download/v0.9.0/devenv_sidechain_notary_disabled.gz"
```
Make sure to update chain dump files with `make get` target.
2. Update `service/morph_chain/protocol.privnet.yml` and disable notary settings
and state root in header.
```yaml
ProtocolConfiguration:
StateRootInHeader: false
P2PSigExtensions: false
ApplicationConfiguration:
P2PNotary:
Enabled: false
```
Chain dump without notary service does not have predefined network map.
Therefore, you need to wait about 5 minutes until new epoch tick with updated
network map.
3. Enable helper commands
To enable helper commands such as `make tick.epoch` or `make update.epoch_duration`
make sure to export non-empty `FROSTFS_NOTARY_DISABLED` environment variable.
```
$ export FROSTFS_NOTARY_DISABLED=1
```
Use `unset` command to return it back.
```
$ unset FROSTFS_NOTARY_DISABLED
```
# Enable notary service in main chain
To enable notary service in main chain do these steps.
1. Update `.env` and choose notary enabled chain dump for main chain.
```
CHAIN_URL="https://github.com/nspcc-dev/neofs-contract/releases/download/v0.9.0/devenv_mainchain.gz"
```
Make sure to update chain dump files with `make get` target.
2. Update `service/chain/protocol.privnet.yml` and enable notary settings.
To enable notary service, use neo-go configuration below.
```yaml

Main chain generates a block once per 15 seconds, so Inner Ring takes about
15-30 seconds to make a notary deposit in main chain after startup. Then
frostfs-dev-env is ready to work.
