Basic-Node Requirements
Basic node operators stake BFC to verify and create blocks. Validators should expect staking rewards if they stake in the network for at least three months. The longer the staking period, the higher the rewards. The rewards consist of:
Self-staking rewards which accrue in proportion to the number of staked tokens
Transaction fees
A portion of nominators' staking rewards (optional)
Technical Requirements
| Hardware | Minimum requirement |
|---|---|
CPU | - x86-64 compatible - Intel Ice Lake, or newer (Xeon or Core series); AMD Zen3, or newer (EPYC) - Simultaneous multithreading disabled (Hyper-Threading on Intel, SMT on AMD) - Prefer single-threaded performance over a higher cores count |
Storage | An NVMe SSD of 1 TB (As it should be reasonably sized to deal with blockchain growth) |
RAM | 16GB DDR4 |
Operating system requirements (Ubuntu 18.04 ~ 22.04 Recommended)
Linux Kernel 5.16 or later
Amazon Linux 2: 5.10.130-118.517.amzn2.x86_64 or later
Bonding Requirements
| Requirements | Amount |
|---|---|
Minimum self-bond | 50,000 BFC |
Minimum voting power (self-bond + total nominated BFC) | 50,000 BFC |
Operating Requirements
Account Management
Validators should securely manage two accounts, Stash and Controller accounts, for self-bonding deposit and consensus participation, respectively.
Stash account: An EVM account for the self-bonding deposit.
Controller account: An EVM account for consensus participation. It should have enough balance for transaction fees used in certain operations.
Required Credentials
Validators require three types of keys as follows:
AURA key for block production
GRANDPA key for block finalization
“Imonline” key to check the node availability
