# G6 Chains Public
# Gen6 Public Blockchain
Public repository of G6 Chains: docs and brand kit.
A customized blockchain built using Substrate, designed to operate independently without relying on a relay chain, but keeping interoperability features.
## Technical Info
**Name:** Gen6 Public Chain
**Internal ID:** g6-solo-chain/107
**G6 SS58 Prefix:** 355
**SS58 Converter to G6 addresses:** [ss58.org](https://ss58.org/)
**Gen6 WSS API:** wss://gen6.app:443/node
**Default CHAIN_PORT:** 9944
**Default RPC_PORT:** 30301
**Explorer:** [PJS Link](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fgen6.app%3A443%2Fnode#/explorer)
**Wallets supported:** SubWallet, PolkadotJS
**Whitepaper:** [Gitbook](https://g6-networks.gitbook.io/g6-networks/)
## Getting Started with Building
Ensure all necessary dependencies are installed according to your platform’s [Substrate installation guide.](https://docs.substrate.io/install/)
### Build
Use the following command to build the node without launching it:
```sh
cargo build --release
```
### Single-Node Development Chain
The following command starts a single-node development chain that doesn't
persist state:
```sh
./target/release/g6-solo-node --dev
```
To purge the development chain's state, run the following command:
```sh
./target/release/g6-solo-node purge-chain --dev
```
To start the development chain with detailed logging, run the following command:
```sh
RUST_BACKTRACE=1 ./target/release/g6-solo-node -ldebug --dev
```
### Run with docker
You need to have docker installed on your system
#### Build
```sh
docker compose -f ./docker_g6/compose_files/solo_chain/builder/docker-compose.yml up
```
#### Run
```sh
docker compose -f ./docker_g6/compose_files/solo_chain/runner/docker-compose.yml up
```
#### Run the live chain
- build the chain
- create and insert keys with the generate_validator_keys.sh from the Scripts project
You will have your secrets in a data folder. There are secrets inside which you should NOT share with anybody.
```shell

```
Run the blockchain
```shell
$SOLO_CHAIN_NODE_EXECUTABLE \
--base-path "$BASE_PATH" \
--chain "$RAW_CHAINSPEC_FILENAME" \
--port "$CHAIN_PORT" \
--rpc-port "$RPC_PORT" \
--validator \
--name "$NODE_NAME"
```
BASE_PATH = the path to the data folder we created with the generate script.
SOLO_CHAIN_NODE_EXECUTABLE = the path to the node executable E.g. <solo_chain_project>/target/release/g6-solo-node
RAW_CHAINSPEC_FILENAME = the raw chainspec. The live raw chainspec is stored in this project
CHAIN_PORT=9944
RPC_PORT=30301
NODE_NAME= any unique name
### Key generation
```sh
./target/release/g6-solo-node key generate --output-type json
```
Example output
```txt
{
"accountId": "0x9e6a8d5406599378f39784cb2f31f8a848d4605177da43d9e1227026a970e51c",

"ss58PublicKey": "5FeR5LJ8jR6SRXeKXFEn61H2ztWxTw4Vvpz9vRrVdhcpuvKk"
}
```
Substrate supports different key types (e.g., sr25519, ed25519, or ecdsa). You can specify the key type using the --scheme flag
```sh
./target/release/g6-solo-node key generate --scheme sr25519 --output-type json
```
Generate Keys for a Specific Network
```sh
./target/release/g6-solo-node key generate --network polkadot
```
Help Command for Details: To explore all available options, use the --help flag:
```sh
./target/release/g6-solo-node key --help

# A guide how to add validators to the network
## Key generation
The validator should generate and insert aura, grandpa and node keys with the [generate_validator_keys.sh script](https://g.g6.network/g6-chain/Scripts/-/tree/main/keys)
Keep all the private keys safe. They should remain secret and only the owner should have access to them.
You should see a generated folder and file structure similar to this:
```shell
data % tree
.
├── aura-sr25519.json
├── chains
│   └── gen6
│   ├── keystore
│   │   ├── 6175726108fd5c07440953c6b8d920e196d4a02fbbfdd2fa2668b6c16aabb8a2280b7f24

│   └── network
│   └── secret_ed25519
├── grandpa-ed25519.json
├── node-key-ed25519.json
└── peer-id.txt
5 directories, 7 files
```
## Extrinsic calls
### Sudo calls
This step could only be done by the owner of the sud keys of the blockchain.
Sudo should add the aura ss58Address to the validator set through the extrinsic
`sudo.sudo( substrateValidatorSet.addValidator( <new_validator_aura_ss58Address> ) )`
### Validator key Calls
This step is done by the owner of the validator keys.
The owner of tha validator keys should add his aura keys to a wallet extension of his choice in order to sign the message later.
The owner of tha validator keys should call the extrinsic substrateValidatorSet.start.
Aura "publicKey" and grandpa "publicKey" should be submitted as parameters to the extrinsic and the transaction should be signed the previously added **aura** keys
Validator aura key calls `substrateValidatorSet.start(auraPublicKey, grandpaPublicKey)`

# A guide how to chill and restore a validator
In order to stop the validator you need to submit and sign the transaction of the chillMe extrinsic.
The validator cant stop itself immediately and needs to wait a specified amount of time before going down.
The "ChillTerm" period is specified in the runtime configuration. [View runtime lib.rs](../runtime/src/lib.rs)
![validator.substrateValidatorSet.chillMe.png](pictures/validator.substrateValidatorSet.chillMe.png)
For going back online there is the restore() extrinsic

# How to do a runtime upgrade
- You need to poses the sudo keys for the chain
- Make sure the runtime spec_version is incremented
- You need to compile the newest chain. A `cargo clean` before that would be advisable.
```shell
cargo clean
```
```shell
cargo build --release
```
- You need to call the sudo.sudo(call) on system.setCode(code) extrinsic with the sudo keys
`sudo.sudo(system.setCode(your_chain.compact.compressed.wasm)) `
- As the "code" argument you need to upload the `g6_solo_runtime.compact.compressed.wasm` from the target folder `target/release/wbuild/g6-solo-runtime/`
![sudo.sudo.system.setCode.png](pictures/sudo.sudo.system.setCode.png)
- To confirm the upgrade was successful you should see the new spec_version in the PJS UI top left
Eg. before: `g6-solo-chain/102`. After `g6-solo-chain/103`

# Installation
This guide is for reference only, please check the latest information on getting started with Substrate [here](https://docs.substrate.io/main-docs/install/).
This page will guide you through the **2 steps** needed to prepare a computer for **Substrate** development. Since
Substrate is built with [the Rust programming language](https://www.rust-lang.org/), the first thing you will need to do
is prepare the computer for Rust development - these steps will vary based on the computer's operating system. Once Rust
is configured, you will use its toolchains to interact with Rust projects; the commands for Rust's toolchains will be
the same for all supported, Unix-based operating systems.
## Build dependencies
Substrate development is easiest on Unix-based operating systems like macOS or Linux. The examples in the [Substrate
Docs](https://docs.substrate.io) use Unix-style terminals to demonstrate how to interact with Substrate from the command
line.
### Ubuntu/Debian
Use a terminal shell to execute the following commands:
```bash
sudo apt update
# May prompt for location information
sudo apt install -y git clang curl libssl-dev llvm libudev-dev
```
### Arch Linux
Run these commands from a terminal:
```bash
pacman -Syu --needed --noconfirm curl git clang
```
### Fedora
Run these commands from a terminal:
```bash
sudo dnf update
sudo dnf install clang curl git openssl-devel
```
### OpenSUSE
Run these commands from a terminal:
```bash
sudo zypper install clang curl git openssl-devel llvm-devel libudev-devel
```
### macOS
> **Apple M1 ARM** If you have an Apple M1 ARM system on a chip, make sure that you have Apple Rosetta 2 installed
> through `softwareupdate --install-rosetta`. This is only needed to run the `protoc` tool during the build. The build
> itself and the target binaries would remain native.
Open the Terminal application and execute the following commands:
```bash
# Install Homebrew if necessary https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
# Make sure Homebrew is up-to-date, install openssl
brew update
brew install openssl
```
### Windows
**_PLEASE NOTE:_** Native Windows development of Substrate is _not_ very well supported! It is _highly_
recommended to use [Windows Subsystem Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10)
(WSL) and follow the instructions for [Ubuntu/Debian](#ubuntudebian).
Please refer to the separate
[guide for native Windows development](https://docs.substrate.io/main-docs/install/windows/).
## Rust developer environment
This guide uses <https://rustup.rs> installer and the `rustup` tool to manage the Rust toolchain. First install and
configure `rustup`:
```bash
# Install
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Configure
source ~/.cargo/env
```
Configure the Rust toolchain to default to the latest stable version, add nightly and the nightly wasm target:
```bash
rustup default stable
rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
```
## Test your set-up
Now the best way to ensure that you have successfully prepared a computer for Substrate development is to follow the
steps in [our first Substrate tutorial](https://docs.substrate.io/tutorials/v3/create-your-first-substrate-chain/).
## Troubleshooting Substrate builds
Sometimes you can't get the Substrate node template to compile out of the box. Here are some tips to help you work
through that.
### Rust configuration check
To see what Rust toolchain you are presently using, run:
```bash
rustup show
```
This will show something like this (Ubuntu example) output:
```text
Default host: x86_64-unknown-linux-gnu
rustup home: /home/user/.rustup
installed toolchains
--------------------
stable-x86_64-unknown-linux-gnu (default)
nightly-2020-10-06-x86_64-unknown-linux-gnu
nightly-x86_64-unknown-linux-gnu
installed targets for active toolchain
--------------------------------------
wasm32-unknown-unknown
x86_64-unknown-linux-gnu
active toolchain
----------------
stable-x86_64-unknown-linux-gnu (default)
rustc 1.50.0 (cb75ad5db 2021-02-10)
```
As you can see above, the default toolchain is stable, and the `nightly-x86_64-unknown-linux-gnu` toolchain as well as
its `wasm32-unknown-unknown` target is installed. You also see that `nightly-2020-10-06-x86_64-unknown-linux-gnu` is
installed, but is not used unless explicitly defined as illustrated in the [specify your nightly
version](#specifying-nightly-version) section.
### WebAssembly compilation
Substrate uses [WebAssembly](https://webassembly.org) (Wasm) to produce portable blockchain runtimes. You will need to
configure your Rust compiler to use [`nightly` builds](https://doc.rust-lang.org/book/appendix-07-nightly-rust.html) to
allow you to compile Substrate runtime code to the Wasm target.
> There are upstream issues in Rust that need to be resolved before all of Substrate can use the stable Rust toolchain.
> [This is our tracking issue](https://github.com/paritytech/substrate/issues/1252) if you're curious as to why and how
> this will be resolved.
#### Latest nightly for Substrate `master`
Developers who are building Substrate _itself_ should always use the latest bug-free versions of Rust stable and
nightly. This is because the Substrate codebase follows the tip of Rust nightly, which means that changes in Substrate
often depend on upstream changes in the Rust nightly compiler. To ensure your Rust compiler is always up to date, you
should run:
```bash
rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
```
> NOTE: It may be necessary to occasionally rerun `rustup update` if a change in the upstream Substrate codebase depends
> on a new feature of the Rust compiler. When you do this, both your nightly and stable toolchains will be pulled to the
> most recent release, and for nightly, it is generally _not_ expected to compile WASM without error (although it very
> often does). Be sure to [specify your nightly version](#specifying-nightly-version) if you get WASM build errors from
> `rustup` and [downgrade nightly as needed](#downgrading-rust-nightly).
#### Rust nightly toolchain
If you want to guarantee that your build works on your computer as you update Rust and other dependencies, you should
use a specific Rust nightly version that is known to be compatible with the version of Substrate they are using; this
version will vary from project to project and different projects may use different mechanisms to communicate this
version to developers. For instance, the Polkadot client specifies this information in its [release
notes](https://github.com/paritytech/polkadot-sdk/releases).
```bash
# Specify the specific nightly toolchain in the date below:
rustup install nightly-<yyyy-MM-dd>
```
#### Wasm toolchain
Now, configure the nightly version to work with the Wasm compilation target:
```bash
rustup target add wasm32-unknown-unknown --toolchain nightly-<yyyy-MM-dd>
```
### Specifying nightly version
Use the `WASM_BUILD_TOOLCHAIN` environment variable to specify the Rust nightly version a Substrate project should use
for Wasm compilation:
```bash
WASM_BUILD_TOOLCHAIN=nightly-<yyyy-MM-dd> cargo build --release
```
> Note that this only builds _the runtime_ with the specified nightly. The rest of project will be compiled with **your
> default toolchain**, i.e. the latest installed stable toolchain.
### Downgrading Rust nightly
If your computer is configured to use the latest Rust nightly and you would like to downgrade to a specific nightly
version, follow these steps:
```bash
rustup uninstall nightly
rustup install nightly-<yyyy-MM-dd>
rustup target add wasm32-unknown-unknown --toolchain nightly-<yyyy-MM-dd>
```

# Aura Module
- [`aura::Config`](https://docs.rs/pallet-aura/latest/pallet_aura/pallet/trait.Config.html)
- [`Pallet`](https://docs.rs/pallet-aura/latest/pallet_aura/pallet/struct.Pallet.html)
## Overview
The Aura module extends Aura consensus by managing offline reporting.
## Interface
### Public Functions
- `slot_duration` - Determine the Aura slot-duration based on the Timestamp module configuration.
## Related Modules
- [Timestamp](https://docs.rs/pallet-timestamp/latest/pallet_timestamp/): The Timestamp module is used in Aura to track
consensus rounds (via `slots`).
## References
If you're interested in hacking on this module, it is useful to understand the interaction with
`substrate/primitives/inherents/src/lib.rs` and, specifically, the required implementation of
[`ProvideInherent`](https://docs.rs/sp-inherents/latest/sp_inherents/trait.ProvideInherent.html) and
[`ProvideInherentData`](https://docs.rs/sp-inherents/latest/sp_inherents/trait.ProvideInherentData.html) to create and
check inherents.

# Identity Module
- [`identity::Config`](https://docs.rs/pallet-identity/latest/pallet_identity/trait.Config.html)
- [`Call`](https://docs.rs/pallet-identity/latest/pallet_identity/enum.Call.html)
## Overview
A federated naming system, allowing for multiple registrars to be added from a specified origin.
Registrars can set a fee to provide identity-verification service. Anyone can put forth a
proposed identity for a fixed deposit and ask for review by any number of registrars (paying
each of their fees). Registrar judgements are given as an `enum`, allowing for sophisticated,
multi-tier opinions.
Some judgements are identified as *sticky*, which means they cannot be removed except by
complete removal of the identity, or by the registrar. Judgements are allowed to represent a
portion of funds that have been reserved for the registrar.
A super-user can remove accounts and in doing so, slash the deposit.
All accounts may also have a limited number of sub-accounts which may be specified by the owner;
by definition, these have equivalent ownership and each has an individual name.
The number of registrars should be limited, and the deposit made sufficiently large, to ensure
no state-bloat attack is viable.
## Interface
### Dispatchable Functions
#### For general users
- `set_identity` - Set the associated identity of an account; a small deposit is reserved if not
already taken.
- `clear_identity` - Remove an account's associated identity; the deposit is returned.
- `request_judgement` - Request a judgement from a registrar, paying a fee.
- `cancel_request` - Cancel the previous request for a judgement.
#### For general users with sub-identities
- `set_subs` - Set the sub-accounts of an identity.
- `add_sub` - Add a sub-identity to an identity.
- `remove_sub` - Remove a sub-identity of an identity.
- `rename_sub` - Rename a sub-identity of an identity.
- `quit_sub` - Remove a sub-identity of an identity (called by the sub-identity).
#### For registrars
- `set_fee` - Set the fee required to be paid for a judgement to be given by the registrar.
- `set_fields` - Set the fields that a registrar cares about in their judgements.
- `provide_judgement` - Provide a judgement to an identity.
#### For super-users
- `add_registrar` - Add a new registrar to the system.
- `kill_identity` - Forcibly remove the associated identity; the deposit is lost.

# Pallet Parking
This is a pallet to icentivize network users to hold their tokens on-chain. The mechanism for this is named "Parking".
## Parking metaphor
Account holders can "park" their tokens in a single parking lot. Tokens take some time to get their parking slot. Then, for each week when tokens are parked, their amount grows according to total amount of parked tokens. Users can request unparking anytime, but they will only receive their tokens next Wednesday, when they are successfully unparked.
## Parking mechanics
### Parking
To park tokens, account should call "park" call and indicate amount to be parked. It is possible to reap account by doing so, but not recommended in general (there is small potential for replay attack if immortal transactions were used). These tokens go into parking lot pool and stay there, while parked amount is stored in separate parking ledger. There is minimal parked amount, it is highly recommended that it is set above ED.
### Rewards computation
On first block after Wednesday midnight, following procedure happens:
1. Total parked amount (and thus all individual parking amount) is increased with accordance to following annual Parking Reward Percentage (PRP) assuming 365.25 days in a year:
in case of 1 - 50k tokens in the parking pool 15% is the PRP
in case of 50k - 100k tokens in the parking pool 14.5% is the PRP
in case of 100k -150k tokens in the parking pool 14% is the PRP
in case of 150k - 200k tokens in the parking pool 13.5% is the PRP
in case of 200k - 250k tokens in the parking pool 13% is the PRP
in case of 250k - 300k tokens in the parking pool 12.5% is the PRP
in case of 300k - 400 tokens in the parking pool 12% is the PRP
in case of 400k - 500 tokens in the parking pool 11% is the PRP
in case of 500k - 600 tokens in the parking pool 10% is the PRP
in case of 600k - 700 tokens in the parking pool 9% is the PRP
in case of 700k - 800 tokens in the parking pool 8% is the PRP
in case of 800k - 900 tokens in the parking pool 7% is the PRP
in case of 900k - 1M tokens in the parking pool 6% is the PRP

There is no mechanics defined outside of these ranges.
2. All newly parked tokens are added to pool and from this moment are considered as parked.
3. Reward coefficient is stored for lazy reward computation.
### Lazy rewards computation
To avoid getting extremely large Wednesday block with many parked accounts, rewards are computed on demand. Using associativity of multiplication (`a(b+c) = a*b + a*c`), we can calculate only total pool size on reward event, but spread individual accounts computation in time (and even get the logic for that off-chain). Now rewards are computed in either of the following:
1. Parking events
2. Unparking events
3. 'apply_rewards' calls
Upon recalculation, updated balance of account is recorded. This could be used to estimate accumulated rewards on demand. This call could be sent from any account for any other account, is harmless and benefitial for the network.
Downside of this approach is that full log of past reward coefficients is stored. Although not particularly large, it is limited from above to keep things clean. Fortunately, automatic trimming is implemented for coefficients that are not needed anymore (no accounts with not calculated rewards remain before the unnecessary coefficient). Thus, occasionally some check should be performed to prevent the list of stored coefficients overgrowing.
These are possible solutions for this:
- Incentivize users to recalculate rewards when those are sufficiently old (silly solution but increases involvement) or make an off-chain robots do it on community funding;
- Implement automated "on idle" recalculation (requires some extra caching logic and thus should be implemented carefully);
- Keep growing cache size with upgrades, as needed
### Unparking
Account can request unparking (possibly partial) anytime by calling `unfreeze`. After this request, rewards are calculated and unparked tokens are delivered to user in frozen form if they were properly parked in the pool or unfrozen if they were not (unfrozen unparking taking precedence). Funds can be unfrozen after the Wednesday or are automatically unfrozed on next parking or unparking by the same account.
### Source of funds and management
Funds are coming from "benefactor" account that should be set by parking manager account (or Root) before the pallet could be used. Funds would be drawn from this account on every Wednesday to grow parking pool. There is no plan on what should happen if this account does not have enough free balance. Maximum amount that could be withdrawn in a week is approximately 1000 tokens. Please make sure benefitiary does not get drained.
Benefitiary account could be changed anytime, but could not be un-set.
## Usage
1. Parking manager or root sets benefitiary account by calling `set benefactor` at least once.
2. Users park, unpark, collect rewards, enjoy.
3. Remember to trim old coefficients when needed (or patch this pallet to do it automatically).
