Fullnode Deployment

System requirements​

This article lists the minimum and recommended system requirements for running Fullnode nodes, which must be run on different machines for Sentinel and Verifier nodes.

Minimum system requirements：

  • RAM: 32 GB
  • CPU: 8-core
  • Storage: 1 TB SSD

For Amazon Web Services (AWS), the equivalent of the minimum requirements instances are m5d.2xlarge or t3.2xlarge with unlimited credits selected.

Recommended system requirements:

  • RAM：64GB
  • CPU: 16-core
  • Storage: 1TB SSD
  • Bandwidth: 1 Gbit/s

For Amazon Web Services (AWS), the recommended example is m5d.4xlarge, for OVH, the recommended example is infra-3, for the network, expect 3-5TB of data transfer per month.

During the process of following the instructions in this section, you will need to wait for the Delivery service and BTTC service to fully synchronise, a process that will take a few hours. Alternatively, you can use an officially maintained snapshot, which will reduce the synchronisation time to a few minutes.

Prerequisites​

One machine.

  • build-essential installed on fullnode machine(optional). To install(only required in ubuntu):
    sudo apt-get install build-essential
  • Go 1.17 installed on fullnode machine. To install:
    wget https://gist.githubusercontent.com/ssandeep/a6c7197811c83c71e5fead841bab396c/raw/go-install.sh
    bash go-install.sh
    sudo ln -nfs ~/.go/bin/go /usr/bin/go

Overview​

To get to running a full node, do the following:

1. Have the one machine prepared.
2. Install the Delivery and Bttc binaries on the fullnode machine.
3. Set up the Delivery and Bttc service files on the fullnode machine.
4. Set up the Delivery and Bttc services on the fullnode machine.
5. Configure the full node.
6. Start the full node.
7. Check node health with the community.

Note: You must follow the exact outlined sequence of actions, otherwise you will run into issues.

Install Binaries​

Install Delivery​

Clone the Delivery repository:

git clone https://github.com/bttcprotocol/delivery

Check out the correct release version:

git checkout RELEASE_TAG

where

  • RELEASE_TAG — the tag of the release version that you install.

Example:

git checkout v1.0.0

Install Delivery:

make install

Check the installation:

deliveryd version --long

Install Bttc​

Clone the Bttc repository:

git clone https://github.com/bttcprotocol/bttc

Check out the correct release version:

git checkout RELEASE_TAG

where

  • RELEASE_TAG — the tag of the release version that you install.

Example:

git checkout v1.0.1

Install BTTC:

make bttc-all

Create symlinks:

sudo ln -nfs ~/bttc/build/bin/bttc /usr/bin/bttc
sudo ln -nfs ~/bttc/build/bin/bootnode /usr/bin/bootnode

Check the installation:

bttc version

Set up fullnode files​

Fetch the launch repository​

Clone the launch repository:

git clone https://github.com/bttcprotocol/launch

Note： Choose the correct folder,if you want to join the mainnet,choose mainnet-v1.otherwise,if you want to join the testnet,choose testnet-1029.make sure don't misuse.

Set up the launch directory​

Create a node directory:

mkdir -p node

Copy the files and scripts from the launch directory to the node directory:

cp -rf launch/mainnet-v1/sentry/sentry/* ~/node

Set up the network directories​

Set up Delivery​

Change to the node directory:

cd ~/node/delivery

Run the setup script:

bash setup.sh
Set up Bttc​

Change to the node directory:

cd ~/node/bttc

Run the setup script:

bash setup.sh

Configure the full node​

Login to the remote fullnode machine.

Configure the Delivery services​

Open for editing vim ~/.deliveryd/config/config.toml.

In config.toml, change the following:

  • moniker — any name. Example: moniker = "my-fullnode".
  • seeds — the seed node addresses consisting of a node ID, an IP address, and a port. Use the following values from ~/node/delivery/delivery-seeds.txt: Example(mainnet):
    seeds="161c2cbe07fccc8c8a3b10ccdea608569a202c06@54.157.35.210:26656,f3f21c82c04003e3c6ee14eb4d11d5dd0b1f201e@107.20.250.182:26656,ed080edbac1a1a285d265e3e87269aea9f6693b7@54.219.27.155:26656,3114d9ebc7254a27de7092b071bd698d250748aa@54.241.235.101:26656"
    Example(testnet-1029):
    seeds="3f562eed0fcfabc848db5ebed81633e340352c0c@52.53.72.234:26656,65f774fece098327b595c971b507db24356000fd@54.176.105.93:26656,8a8944fcaddb46ff18ec59a3197af1c5763eb824@50.18.50.100:26656,7ece43f437d4dc419bdf9c09604ebed084699779@54.215.2.221:26656"
  • pex — set the value to true to enable the peer exchange. Example: pex = true.
  • prometheus — set the value to true to enable the Prometheus metrics. Example: prometheus = true.
  • max_open_connections — set the value to 100. Example: max_open_connections = 100.

Save the changes in config.toml.

Open for editing vim ~/.deliveryd/config/delivery-config.toml.

In delivery-config.toml, change the following:

  • eth_rpc_url: Ethereum network rpc address. You need to generate INFURA_KEY yourself in order to communicate with Ethereum. API_KEY Application Tutorial
  • tron_rpc_url: RPC address of TRON network node. choose from official-public-node
  • tron_grid_url: TRON Network event service query url.
  • bsc_rpc_url: RPC address of BSC network node.official-rpc-node
  • checkpoint_poll_interval: checkpoint poll interval.please set this param to 30m0s.

Example(mainnet):

vim ~/.deliveryd/config/delivery-config.toml
  
eth_rpc_url = "https://mainnet.infura.io/v3/<YOUR_INFURA_KEY>" 
bsc_rpc_url = "https://bsc-dataseed.binance.org/" 
tron_rpc_url = "grpc.trongrid.io:50051" 
tron_grid_url = "https://tronevent.bt.io/"

Example(testnet-1029):

vim ~/.deliveryd/config/delivery-config.toml
  
eth_rpc_url = "https://goerli.infura.io/v3/<YOUR_INFURA_KEY>" 
bsc_rpc_url = "https://data-seed-prebsc-1-s1.binance.org:8545/"
tron_rpc_url = "47.252.19.181:50051" 
tron_grid_url = "https://test-tronevent.bt.io"

Configure the Bttc Service​

Open for editing vi ~/node/bttc/start.sh.

In start.sh, add the boot node addresses consisting of a node ID, an IP address, and a port by adding the following line at the end:

mainnet Configure:

--bootnodes 
"enode://8ef920be1d44ad7c41a517a6420e43511f2e30d1c35a4bb05954c9f413b1712dae6e9e05f56595966470506891ff05d203e233c2e8f6df8c72621537a3d783e9@54.157.35.210:30303,enode://f3a2534ac30db7387f84c1262bce9a0737c46a8b5627f8193d412a4bde415c191191bbf984f51e04e5d974e62b70fab148f38522c5e2917ca1f1860361f14cc9@107.20.250.182:30303,enode://268cc5c4062b4c30f7ae972322ec119465655d9b3f7220df4614f2890b5cef6ac350d65890f8ecebfe6c5ce0af635f7ae420db84de7677c54b35ed1ce6bb4fbd@54.219.27.155:30303,enode://a9aa7a7ec5b34485c73436d311d86c55f900db4008058231a2fd2fb8ee7ad1b68d7d5a64acbf1f62b8d5f25388b492d16befb686d6146b374a85a6ea7d5a95c9@54.241.235.101:30303"

Testnet-1029 Configure:

--bootnodes "enode://2e6a732ba9d0fcf102a4f4bda7d76f28095c9f03ee56bc89dc5c2235cd527c914b6063b0c76598cc37287f0594ae4022df550c592b3ba2a56a9f02810edbeee1@52.53.72.234:30303,enode://3d7da6d583072fbbe733135047010698e8b6a24c9315ce953b09dddbfabb2476c8b720b2ff2beb2ec73ef111b691c7dcd87f5e42bcba4a7bc385b7f728b2ab44@54.176.105.93:30303"

Save the changes in start.sh.

Configure firewall​

The full machine must have the following ports open to the world 0.0.0.0/0:

  • 26656- Your Delivery service will connect your node to other nodes Delivery service.
  • 30303- Your Bttc service will connect your node to other nodes Bttc service.
  • 22- For the fullnode to be able to ssh from wherever he/she is.

Start the full node​

You will first start the Delivery service. Once the Delivery service syncs, you will start the Bttc service.

Note：The Delivery service takes several hours to fully sync from scratch.

Start the Delivery service​

Change to the ~/node/delivery directory:

cd ~/node/delivery

Start the Delivery service:

bash delivery-start.sh

Start the Delivery rest-server:

bash delivery-server-start.sh

Note：

In the logs, you may see the following errors:

  • Stopping peer for error
  • MConnection flush failed
  • use of closed network connection

These mean that one of the nodes on the network refused a connection to your node. You do not need to do anything with these errors. Wait for your node to crawl more nodes on the network.

Check the sync status of Delivery:

curl localhost:26657/status

In the output, the catching_up value is:

  • true — the Delivery service is syncing.
  • false — the Delivery service is fully synced.

Wait for the Delivery service to fully sync.

Start the Bttc service​

Once the Delivery service is fully synced, start the Bttc service.

Change to the ~/node/bttc directory:

cd ~/node/bttc

Start the Bttc service:

bash start.sh
