-# N3 NeoFS side chain privnet service
-A single-node N3 privnet deployment, running on
-[neo-go](https://github.com/nspcc-dev/neo-go). Represents N3 NeoFS SideChain.
-
-Contracts deployed:
-- Alphabet (AZ) [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/alphabet)
-- Audit [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/audit)
-- Balance [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/balance)
-- Container [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/container)
-- Netmap [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/netmap)
-- NeoFSID [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/neofsid)
-- Proxy [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/proxy)
-- Reputation [contract](https://github.com/nspcc-dev/neofs-contract/tree/master/reputation)
- 
-RPC available at `http://morph-chain.neofs.devenv:30333`.
-
-## .env settings
-
-### NEOGO_VERSION
-
-Version of neo-go docker container for side chain deployment.
-
-## Side chain wallets
-
-There is a wallet with GAS that used for contract deployment:
-`wallets/wallet.json`. This wallet has one account with **empty password**.
-
-```
-$ neo-go wallet nep17 balance \
-    -w wallets/wallet.json \
-    -r http://morph-chain.neofs.devenv:30333
-
-Account NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM
-GAS: GasToken (d2a4cff31913016155e38e474a2c06d08be276cf)
-        Amount : 189826.0515316
-        Updated: 3909
-NEOFS: NeoFS Balance (69550190e740b93f92dbd5dea52246f550391057)
-        Amount : 50
-        Updated: 3909
-```
-
-This way you can also monitor NeoFS internal balance of your account.
-
-## NeoFS global config
-
-NeoFS uses global configuration to store epoch duration, maximum object size, 
-container fee and other network parameters. Global configuration is stored in
-netmap contract and managed by Inner Ring (Alphabet) nodes.
-
-To change these parameters use `make update.*` commands. Command down below
-changes epoch duration from 300 blocks (about 300 seconds with 1bps) to 30.
-Script enters passwords automatically with `expect` utility.
-
-```
-$ make update.epoch_duration val=30
-Changing EpochDuration configration value to 30
-Enter account NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP password > 
-Sent invocation transaction bdc0fa88cd6719ef6df2b9c82de423ddec6141ca24255c2d0072688083b1de9d
-Updating NeoFS epoch to 20
-Enter account NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP password > 
-Sent invocation transaction 12296e1ce24dd6c04edb9c56d0a1d0e26d3226adefb0333c74a28788f44a8d0f
-```
-
-Read more about available configuration in Makefile help.

-```
