Install Update and Dependencies

1. Download Binary​

If you do not want to compile the source code for installation, please proceed directly to package installation.

Getting source code

cd $HOME
mkdir tfsc
cd tfsc
wget https://fastcdn.tfsc.io/formal/tfs_v1.0.2_524b745_primarynet.zip
unzip tfs_v1.0.2_524b745_primarynet.zip
rm -rf tfs_v1.0.2_524b745_primarynet.zip

Create Config FIle

./tfs_v1.0.2_524b745_primarynet -c
edit config file

Ensure that the time of each node is the same and that the transaction is reliable when it is linked

nano config.json
{
    "http_callback": {
        "ip": "",
        "path": "",
        "port": 0
        },
    "http_port": 20620,
    "info": {
        "logo": "",
        "name": ""
        },
    "ip": "192.168.1.1",
    "log": {
        "console": false,
        "level": "OFF",
        "path": "./logs"
        },
    "rpc": false,
    "server": [
        "13.52.162.66",
        "52.52.118.136"
        ],
    "server_port": 20619,
    "version": "1.0"
}

Modify config.json file​

"server" field: This field fills in any ip node in the Transformers network,Obtain IP information of other nodes through the http://yournode:http_port/pub interface.

"server_port" field: This field is the network connection port number (it does not need to be changed by default)

"Log" field: "Console" indicates whether the log is output on the screen;"Level" indicates the level of output log;"Path" indicates the path of the default log generation.

"Ip": the system will detect the local ip and automatically fill in this field when starting.

"Http_port": the port of the http service.

"Rpc": the switch of the access interface, the interface can be accessed when it is turned on, and it is turned off by default.Introduction of specific application scenarios in Developers

"Info": the logo and name of the node set by the user.

"Http_callback": http callback interface,Introduction to specific application scenarios in Callback interfaces.

"Version": the version of the config file.

To view the automatically generated directories and files under the current directory.

cd  tfs_v1.0.x_xxxx_testnet
Files or directories Type Description
cert folder Store the generated private key with the suffix ".private" as a private key file
data.db folder Store database file
logs folder Store log file
config.json json file configuration file
tips:

Protect your private key

  1. The private key in the cert must not be lost.

Open corresponding port shall be port 20619、port 20620.

Start The Node​

Directly start the program

./tfs_v1.0.x_xxxx_testnet

Add parameter[ -m ] to start the program to display menu

./tfs_v1.0.x_xxxx_testnet -m

Time display box​

UTC time and server time display:

UTC Time: 2024/01/19 02:00:24
Ntp Time: 2024/01/19 02:00:24
ThreadNumber:265
caution

The validator server must be consistent with UTC time, and not synchronizing will result in the inability to verify transactions

Account display box​

Account information display:

Order Menu Items Function
1 Transaction Validator provides command line transfer function, and can complete TTOS transfer according to prompts
2 Stake Becoming a validator node requires staking a certain amount of TTOS
3 Unstake Revoke your stake operation. Please understand the stake rules before revoking
4 Delegate Delegate TTOS to validators to obtain revenue,is equivalent to investing
5 Withdraw Revoke your investment in validators
6 Get Bonus The validator needs to claim its own rewards every day in order for delegators to receive their investment dividends
7 PrintAccountInfo Print account information,View your own balance changes and block heights
8 Deploy contract deployment smart contract
9 Call contract Execute smart contract
10 Account Manager 0. Exit
1. Set Default Account
2. Add Account
3. Remove
4. Import PrivateKey
5. Export PrivateKey
0 Exit Exit the program

As an RPC node​

If you want your validator to act as an RPC node, it only takes a few simple steps to complete.

  • Modify the config.json file and set rpc to true
 "rpc": true,
  • Configure the value of http_port as the HTTP access port.
 "http_port": 20620,

Complete configuration example:
Enable RPC node service and set callback interface

{
    "http_callback": {
        "ip": "192.168.1.123",
        "path": "/path/rollback_block",
        "port": 6071
    },
    "http_port": 20620,
    "info": {
        "logo": "",
        "name": ""
    },
    "ip": "192.168.1.119",
    "log": {
        "console": false,
        "level": "debug",
        "path": "./logs"
    },
    "rpc": true,
    "server": [
        "192.168.1.217",
        "192.168.1.126"
    ],
    "server_port": 20619,
    "sync_data": {
        "count": 50,
        "interval": 50
    },
    "version": "0.39"
}
  • Restart the tfs program after the settings are complete

To test whether the RPC node is enabled, you can query the node information for detection.
