BOOLNetwork Guidance

Instructions

Before starting, please cofirm on Intel© Ark whether your processor is compatible with Intel© SGX.

Start by cloning the repository.

git clone https://github.com/boolnetwork/mining-scripts.git

SGX

Inspect your system's SGX support with:

./sgx-detect

Install sgx driver:

apt update
apt install  build-essential  automake autoconf libtool wget python libssl-dev dkms
wget https://download.01.org/intel-sgx/latest/linux-latest/distro/ubuntu18.04-server/sgx_linux_x64_driver_1.41.bin
bash sgx_linux_x64_driver_1.41.bin

Sample Output:

If it displays as ✘ SGX kernel device (/dev/sgx_enclave), We should install SGX Environment and restart with:

sudo chmod +x sgx_enable
sudo ./sgx_enable
sudo reboot

Running the Service

After confirming that your machine supports SGX2, you can proceed to launch the keyring service. The keyring service relies on obtaining events and state from a node service. In the configuration file, it is advisable to use an official node as the data source. Alternatively, you can initiate a local full node and utilize it as a data source once data synchronization is finished.

Preparing an Account

Before initiating the process, you must create an account to serve as the owner responsible for holding and managing the current keyring service.

Option 1

Generate an account using the command docker run -it --rm boolnetwork/bnk-node:release identity generate.

You will receive an output like this:

Secret seed:      0x71235e1458ce9d140c8b8ded28ccc1e32e62c340aef51a65e1350a387dbe08a6
Public key (hex): 0x0248e7f02dcc9f7061a090b67dede93d7381847e94955aee7996603d2225e9f77e
Account ID:       0x34a5572cb21d34354e3091564d5edc7b791e9d5f

Secret seed signifies the account's private key, which can be directly imported into wallets such as MetaMask. Account ID represents the account's address.

Option 2

An alternative approach is to create an account using MetaMask since BoolNetwork's account system is Ethereum-compatible.

We recommend using MetaMask here because subsequent operations will require interaction with the boolscan dashboard, which currently exclusively supports MetaMask.

Preparing Coin

Prepare some tBOL with your address to make sure for the deployment.

Configuration Modification

For the majority of users, just substitute the device_owner in the default configuration file with the Account ID created in the previous step. There is no need to modify other parameters.

For example： Open the keyring.toml file under the configs directory and replace 0x00000000000000000000000000000000000000with your <Account ID>。

The default configuration file, encompassing identity information, service ports, P2P network, service launch types, etc., is as follows：

node_ws_url = "ws://127.0.0.1:9944"
# local node_call server port.
node_call_port = 8720
# the owner address of device （ETH type format）
device_owner = "0x00000000000000000000000000000000000000"
# database path
db_path = "/host/data"
# tokio console port
console_port = 5555

# database start option
[db_option]
create_if_missing = true
atomic_flush = true

[network_config]
protocol_id = "betatestnet"
port = 38700
boot_nodes =["/ip4/172.210.130.200/tcp/38701/p2p/12D3KooWQBrkBWb3tLoUpxqXebxg1Eab24LfcFP3hv37ZF2c6qgz","/ip4/20.81.161.179/tcp/38701/p2p/12D3KooWMDqap7HMjA6nos1HpHpWt8JBcPepnZgYSd5PPmovAqD7"]
share_peer_interval = 30
is_mdns = true
is_autonat = true
only_global_ips = true
#max_peers_connected = 50
#peer_key = "0x0000000000000000000000000000000000000000000000000000000000011111"
#external_multiaddrs = ["/ip4/127.0.0.1/tcp/38700"]

[key_server_config]
attestation_style = 2 #This corresponds to using an image, epid=1, dcap=2
seal_policy = "MRENCLAVE"
exe_policy = { Multiply = { executors = 8 } }
round_time_limit = 180
clear_msg_interval = 360

Parameter Descriptions:

• node_ws_url: The accessible endpoint of the node service. If using a local port, it might be ws://127.0.0.1:9944.

• node_call_port: The port number through which the keyring service is exposed to the outside world.

• identity: The owner of the keyring service, a crucial factor affecting income and penalties for providing services.

• db_path: The storage path for the keyring service to persist data. It is not recommended to modify this. If you need to change it, please refer to the occlum file system.

• db_option.create_if_missing: Runtime parameters for the RocksDB database exposed by the keyring service.

• db_option.atomic_flush: Runtime parameters for the RocksDB database exposed by the keyring service.

• network_config.protocol_id: The division of P2P network protocols is particularly important. Different networks have different protocol_id. Please follow the official configuration, otherwise the link will be invalid.

• network_config.port: The local port number for the keyring service's P2P.

• network_config.is_mdns: MDNS discovery enabled.

• network_config.is_autonat: Autonat discovery enabled.

• network_config.max_peers_connected: Maximum number of nodes allowed to be connected.

• network_config.boot_nodes: Information for the keyring service's P2P module to connect to other services. If configured incorrectly, it will become an isolated node and cannot participate in the service.

• network_config.share_peer_interval: The interval at which the keyring service's P2P module outputs the number of node connections.

• network_config.only_global_ips: Whether the keyring service's P2P module only manages public IP addresses.

• network_config.peer_key: Specifies the keyring service's P2P identity information. If not filled, it will be generated randomly.

• key_server_config.attestation_style: The mode of SGX remote attestation for the keyring service, where 1 represents EPID and 2 represents DCAP.

• key_server_config.seal_policy: The data encryption method for the keyring service, supporting MRSIGNER and MRENCLAVE. It has the same meaning as Intel SGX sealing. MRSIGNER trusts the software publisher, and the advantage is that it is compatible with historical data after software upgrades. MRENCLAVE only trusts the code, and the disadvantage is that it cannot read historical data after software upgrades.

• key_server_config.exe_policy: Optional execution engine that affects software execution efficiency. Generally, it does not need to be changed.

• key_server_config.round_time_limit: The waiting time in seconds for data interaction between keyring services. The session ends if it exceeds the waiting time.

• key_server_config.clear_msg_interval: The interval in seconds for the keyring service to clear abnormal data.

We employ Docker Compose for service management. If you need to specify a storage directory, you can modify the disk mapping in the docker-compose.yaml file to ./data. By default, the data for the keyring service is stored in the same directory as the docker-compose.yaml file.

volumes:
    - ./configs:/configs
    - ./data:/root/occlum_instance/data

Note: /root/occlum_instance/data is an internal directory within Occlum and does not require modification.

Startup and Maintenance

Before starting, we should check if docker compose is installed on the system. You can check this by running docker compose --version or docker-compose --version. If it's not installed, you'll need to install it.

# install docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version

To start and view logs, use the following commands:

docker-compose up -d
docker-compose logs -f 

Wait for the software to run. In case of any errors, consult the FAQ.

If the software is running correctly, you will observe logs similar to the following in the terminal:

register sgx: "0x13bec2ac21b038d885d49d8100d307ce7761cf890bbdf25962a0eb2f2ac18101"

Login your device_owner account to Boolscan's DHC device, unlisted devices will initially appear in the device list:

All subsequent actions will require Metamask signature. Please verify that the connected account in Metamask matches the device_owner account in your keyring.toml file to ensure consistency.

Update Device

Go to the Boolscan's DHC device to activate the device. You need to vote tokens for the first time.

For quick start, we need to stake 20000tBol at a time, and then click the Submit button.

Wait for a epoch, and after the total stake amount reaches the condition (20000tBol), participate in the service through the 'Join Service'.

When you see the device status change to Service, congratulations - the process is complete.

Check if the software is running correctly, indicated by the following logs: HeartBeat session: 40167, challenge: [124, 148, 169, 145, 235, 214, 178, 134, 90, 10, 228, 25, 131, 65, 254, 0, 98, 93, 83, 204, 48, 182, 48, 209, 19, 158, 45, 233, 49, 254, 25, 129], hash: "0xa746ff7daae0952967cc9eadb38e6627052cd073cf0a319cb8fcb65e0abdabef"

Exiting the Service (if required)

Note: The system penalizes malicious nodes by deducting their staked tokens. To avoid financial losses due to irregular exits, please follow the process below to exit.

Exit the service by executing Exit Service:

After executing Exit Service, you need to wait for a epoch before you can execute Remove Device. You can't perform any operations during this period.

Finally, stop your keyring service.

docker compose down

FAQ

If there is no device registration information on Boolscan or you receive the error message： register failed for "Rpc error: RPC error: RPC call failed: ErrorObject { code: ServerError(1010), message: \"Invalid Transaction\", data: Some(RawValue(\"Custom error: 28\")) }

It indicates that keyring version number does not match.

If you encounter an error during startup with the message: [get_platform_quote_cert_data ../qe_logic.cpp:388] Error returned from the p_sgx_get_quote_config API. 0xe011. Or [get_platform_quote_cert_data ../qe_logic.cpp:378] Error returned from the p_sgx_get_quote_config API. 0xe019

0xe011 means "The platform library doesn't have any platfrom cert data". If you set up the PCCS service by yourself, please follow intel guide strictly. If you run in cloud, Use the pccs service provided by the cloud service provider.
