Adding a new producer to the blockchain network

The currently deployed network (165.22.134.182) includes 2 producers running on same server. The network producer status can be viewed here:

https://feesimpletracker.io/producers

The following instructions describe the steps for adding a new producer to the network. For this example, the new producer named prodwallet11 is located on the feesimplewallet server.

Need a staked account

Create a new account named prodwallet11 with https://fsmanager.io Can also request faucet with https://feesimplewallet.io/

Remember to store the private key :)

Deploy a producer on new server

A running producer normally occupies between 1.5GB RAM and 2GB RAM. However, your server should have min 4GB RAM.

Access to the server.

Download and install the EOSIO software (including nodeos, cleos and keosd) version 1.6 https://github.com/EOSIO/eos/releases/tag/v1.6.0

Git clone the following:

git clone https://github.com/FeeSimple/add-block-producer.git

cd in the sub-folder start-new-producer

To start the producer:

• Set the params producerKeyPair and producerName in the script script_start_producer.sh

• To start the producer, run this cmd ./script_start_producer.sh

• To see log output, run this cmd tail -f stderr

• To restart the producer with preserved blockchain data, run this cmd ./script_restart_producer.sh.

Register the producer

This can be done on your localhost or any other server that has the cleos and keosd installed.

Execute the following commands:

1. Start wallet manager keosd

keosd --http-server-address=127.0.0.1:6666 --http-validate-host=false &

2. Create wallet (if not yet)

cleos wallet create --to-console

or unlock the existing wallet

cleos --wallet-url http://localhost:6666 wallet unlock

3. Check the list of current producers

cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 system listproducers

4. Import priv key of the producer account to be registered (e.g. prodwallet11)

cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 wallet import --private-key 5JhV5JtjxfKH8rYmoq75fSa8kJMKexLnB74cC48C1uCvgCwZBzR

5. Register the producer with its pub key

cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 system regproducer prodwallet11 EOS7d4fQXjJnvsverft9ooGd2YnkzSd1xRLgFAUA6BrwDctUavxtt https://prodwallet11.com/EOS7d4fQXjJnvsverft9ooGd2YnkzSd1xRLgFAUA6BrwDctUavxtt

6. Approve the producer from any other user account (e.g. usertrung123)

cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 system voteproducer approve usertrung123 prodwallet11

Notice

Private key of the voting user account (e.g. usertrung123) must be imported before being able to use it

7. Check if the new producer is incorporated into the network by viewing this:

https://feesimpletracker.io/producers

Notice

The producer name is identical to the account name used in the command system regproducer

Unregister the producer from the network

This is done by executing the following commands:

// Unapprove producer
cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 system voteproducer unapprove usertrung123 prodwallet11

// Unregister as producer
cleos --wallet-url http://localhost:6666 --url http://165.22.134.182:8877 system unregprod prodwallet11

Notice

After unregistered, the producer is still producing blocks and is not removed from the active producer list. An explanation can be found here:

EOSIO/eos#5531

Stop the producer

To turn off the producer so that it stops producing blocks, simply terminate the producer process.

// Find the producer proc ID
ps aux | grep nodeos

// Kill it
kill -9 {PID}

If this does not work, perform the following steps:

cd to folder of bios-boot-tutorial

cd ~/eos-release1.1/tutorials/bios-boot-tutorial

Cleanup

pm2 delete all
./cleanup.sh`

Run the bios-boot-tutorial script for deploying the network

pm2 start script_bios_boot.sh

cd to folder bios_boot_script

cd ~/bios_boot_script

kill MongoDB server

killall mongod

Start MongoDB server

./script_mongo_start.sh

Observe MongoDB server log with ./script_mongo_view_log.sh

cd to the client node folder

cd ~/eos-tracker/nodeos/client_node_connect_to_network_mongo

Start the client nodeos

rm -rf blocks
rm -rf state
pm2 start script_client_nodeos.sh
