# NeoFS smart-contract
This smart-contract controls list of NeoFS Inner Ring nodes and provides
methods to deposit and withdraw assets. These assets are used as a payment and
a reward for data storage.
This smart-contract controls list of NeoFS Inner Ring nodes, user assets in
NeoFS balance contract and stores NeoFS runtime configuration.
## Getting Started
This repository contains:
- NeoFS smart-contract written in Go
- Unit tests for the smart-contract
- NeoFS smart-contract in Go
### Prerequisites
To compile smart-contract you need:
- [neo-go](https://github.com/nspcc-dev/neo-go) >= 0.74.0
To run tests you need:
- [go](https://golang.org/dl/) >= 1.12
- [neo-go](https://github.com/nspcc-dev/neo-go) >= 0.90.0
## Compiling
To compile smart contract run `make build` command. Compiled contract
`neofs_contract.avm` will be placed in the same directory.
`neofs_contract.nef` and manifest `config.json` will be placed in the same
directory.
```
$ make build
neo-go contract compile -i neofs_contract.go

## Running the tests
`neofs_contract_test.go` file contains tests for most of the provided methods.
It compiles smart-contract and uses instance of the NeoVM to run
code.
To test smart contract run `make tests` command.
```
$ make tests
go mod vendor

### Skipped tests
Some tests might be skipped for now. These tests used `neofs-node`
structures, that are not publicly available yet, e.g. cheque for
`InnerRingUpdate` call.

/*
NeoFS Smart Contract for NEO3.0.
Utility operations, executed once in deploy stage:
- Init(pubKey, ... ) - setup initial inner ring nodes
- InitConfig(key, value, key, value...) - setup initial NeoFS configuration
User operations:
- Deposit(script-hash, amount, script-hash(?)) - deposit gas assets to this script-hash address to NeoFS balance
- Withdraw(script-hash, amount) - initialize gas asset withdraw from NeoFS balance
- Bind(script-hash, pubKeys...) - bind public key with user's account to use it in NeoFS requests
- Unbind(script-hash, pubKeys...) - unbind public key from user's account
Inner ring list operations:
- InnerRingList() - returns array of inner ring node keys
- InnerRingCandidates() - returns array of inner ring candidate node keys
- IsInnerRing(pubKey) - returns 'true' if key is inside of inner ring list
- InnerRingCandidateAdd(pubKey) - adds key to the list of inner ring candidates
- InnerRingCandidateRemove(pubKey) - removes key from the list of inner ring candidates
- InnerRingUpdate(id, pubKeys...) - updates list of inner ring nodes with provided list of public keys
Config operations:
- Config(key) - returns value of NeoFS configuration with key 'key'
- ListConfig() - returns array of all key-value pairs of NeoFS configuration
- SetConfig(id, key, value) - set key-value pair as a NeoFS runtime configuration value
Other utility operations:
- Version - returns contract version
- Cheque(id, script- hash, amount, script-hash) - sends gas assets back to the user if they were successfully
locked in NeoFS balance contract
Parameters:
- (?) - parameter can be omitted
- pubKey - 33 bytes of public key
- id - unique byte sequence

Utility operations - they will be changed in production:
- Deploy(params: address, pubKey, ... ) - setup initial inner ring state
User operations:
- InnerRingList() - get list of inner ring nodes addresses and public keys
- InnerRingAddress(params: address, pubKey) - update address of the inner ring node with given public key
- InnerRingCandidateRemove(params: pubKey) - remove node with given public key from the inner ring candidate queue
- InnerRingCandidateAdd(params: address, pubKey) - add node to the inner ring candidate queue
- Deposit(params: pubKey, amount) - deposit GAS to the NeoFS account
- Withdraw(params: withdrawCheque) - withdraw GAS from the NeoFS account
- InnerRingUpdate(params: irCheque) - change list of inner ring nodes
- Version() - get version of the NeoFS smart-contract
Params:
- address - string of the valid multiaddress (github.com/multiformats/multiaddr)
- pubKey - 33 byte public key
- withdrawCheque - serialized structure, that confirms GAS transfer;
contains inner ring signatures
- irCheque - serialized structure, that confirms new inner ring node list;
contains inner ring signatures
