Introduction

In VEE blockchain system, only supernodes have the right to minting blocks and getting VVV rewards. In this wiki we will give you details on deploying a supernode. Additionally, a few recommendations are provided to increase security of the blockchain and the safety of your coins. We assume you have read How to install VEE testnet Node and VEE Testnet Node Configuration File. You are recommended to deploy a supernode on testnet first.

Prerequisites

• A VEE wallet (wallet.dat file： wallet generator)
• 50k VVV + 1 million effective balance (regular balance + leased in - leased out)

Contend a minting slot

Once you meet the prerequisites, you are able to contend for a minting slot. Check the slot information from our public API or your local node at /consensus/allSlotInfo. Choose a minting slot that you want to contend. Then you could contend the minting slot you chosen through /spos/contend or /spos/broadcast/contend. The contended slot can be empty or occupied. When you contend, the system will charge you 50k VVV as contending fee and check your remaining effective balance which should no less than 1 million for a successful contention. If the contended slot was empty, your account would occupy that slot successfully. If the contended slot was originally occupied by another account, the system would compare the minting average balance (MAB) of your account with that account, and your contention would be successful only when your MAB is higher. If you failed due to insufficient MAB, your contending fee would NOT be returned.

• Note: Now we have opened 15 slots in mainnet, only those slots with the ID numbers that can exactly divided by 4 are available.

Wallet and reward settings

To make your VVV secure, we recommend you set your account to be a cold minting status.

• Store your huge amount of VVV in your cold wallet and lease money to the account that you are going to contend a minting slot
• Set the reward address to be your cold wallet address (refer to Minter settings at VEE Testnet Node Configuration File, VEE Mainnet Node Configuration File)

API settings

We strongly recommend you setup a standby node and disable API of your minter (refer to REST API settings at VEE Testnet Node Configuration File, VEE Mainnet Node Configuration File)
