2 Download Software

Download the bvcadt.tar.gz file. After decompression, the following files are included:

bvcadtd
bvcadt-core.cfg
validators.txt 
start.sh
libprotobuf.so.8 
libstdc++.so.6

3 Installation Deployment

3.1 Deploy the executable directory

mkdir /usr/local/bvcadt
mv test/bvcadtd /usr/local/bvcadt/
mv test/start.sh /usr/local/bvcadt/

3.2 Deployment configuration file directory

mv test/bvcadt-core.cfg /usr/local/bvcadt
mv test/validators.txt /usr/local/bvcadt

3.3 Deploy dependent library file directory

mv test/libprotobuf.so.8 /usr/lib/x86_64-linux-gnu/libprotobuf.so.8 
mv test/libstdc++.so.6 /usr/lib/x86_64-linux-gnu/libstdc++.so.6

3.4 Inform the node IP

Contact the BVC-Chain service provider (service@bvcadt.com) and provide the node IP to apply to join the BVC-Chain test chain.

4 Script Starts Running

4.1 Start(Test network)

./start.sh

Execute the startup script, your node will synchronize the historical ledger information from other nodes of the BVC-Chain network.

4.2 Verify if the startup is successful

Execute the following command:

./bvcadtd peers

Return the following response message:

{
   "id" : 1,
   "result" : {
      "cluster" : {},
      "peers" : [
         {
            "address" : "10.0.11.34:41718",
            "complete_ledgers" : "1 - 1393550",
            "inbound" : true,
            "latency" : 0,
            "load" : 27,
            "public_key" : "n9L4wHDc7RLjNaPZgzMvNFrGbFYQWo9SEtULer5RVatDTXReAJxe",
            "uptime" : 14000900,
            "version" : "bvcadtd-0.0.3"
         }
}

Return data has information on other BVC-Chain Core node servers, indicating that the blockchain public service network has been successfully connected.

5 Test network transferred to official network

Step 1: Stop the service

./bvcadtd stop

Step 2: If the test network node is upgraded directly to a official network node, the database synchronized from local network needs to be deleted first.

rm –rf /usr/local/bvcadt/db

Step 3: Contact BVC-Chain Service Provider (service@bvcadt.com) to obtain and update the official network configuration file.

mv official/bvcadt-core.cfg /usr/local/bvcadt/
mv official/validators.txt /usr/local/bvcadt/

Step 4: Inform the BVC-Chain service provider of the official network node IP and apply to join the BVC-Chain official website.

Step 5: Execute the startup script follow the "4 Script Starts Running" section.

6 Interface instruction

Refer to the JSON-RPC API section.
