Fuse Network is operated by validator nodes hosted by participants around the world. Validators run the software that holds a copy of the blockchain, groups and validates transactions every 5 seconds, and signs new blocks. In return, they earn newly minted FUSE tokens and transaction fees. Anyone who meets the stake requirement and technical prerequisites can become a validator — the process is entirely permissionless.Documentation Index

Who should become a validator?
Companies building on Fuse can own a piece of the network, earn rewards as it grows, and participate in governance decisions that affect the infrastructure they depend on. Third-party service providers — such as KYC providers, exchanges, or lenders operating across chains — can become network stakeholders and gain reliable, first-class access to Fuse infrastructure. Community operators on Fuse who already run communities and payments products can upgrade to validator status to provide better service to their users and earn rewards.Running a validator node requires a technical background in blockchain infrastructure and web hosting. If you prefer to participate without operating infrastructure, you can delegate your FUSE tokens to an existing validator instead.
Stake and validator set selection
The stake counted for a validator is the sum of its own staked FUSE and all tokens delegated to it by other holders. At the end of each cycle (~2 days, 34,560 blocks), the Consensus contract selects a new validator set from a random snapshot of all pending validators whose total stake meets the 100,000 FUSE minimum. The 100-validator cap and minimum stake requirement together guard against Sybil attacks: creating multiple validators is costly enough to deter cheap identity duplication.Block rewards and fee distribution
The validator who publishes a block earns:- Newly minted FUSE tokens — the protocol distributes 5% yearly inflation as block rewards, updated each block by the BlockReward contract.
- Transaction fees — fees paid by users for transactions included in the block.
Jailing
Validators are expected to remain online and follow consensus rules. Violating those rules — such as producing invalid blocks or missing block slots — results in jailing:How to become a validator
Acquire at least 100,000 FUSE
Obtain the minimum required stake of 100,000 FUSE tokens. You can use your own stake, or a combination of your own stake and delegated tokens from other holders, as long as the total meets the minimum.
Set up a full node
Run the Fuse full node software. Your node must maintain a complete copy of the blockchain and be reachable by the network at all times. Refer to the node setup documentation for configuration details and hardware recommendations.
Stake your FUSE
Lock your FUSE tokens in the Consensus contract to register as a pending validator. You have two options:
- Send FUSE directly to the Consensus contract address
0x3014ca10b91cb3D0AD85fEf7A3Cb95BCAc9c0f79on Fuse Network. - Call the
stakefunction on the Consensus contract.
Wait for the next cycle snapshot
Once staked, your address becomes a pending validator. The Consensus contract takes snapshots of pending validators throughout each cycle (~2 days). At cycle end, a random snapshot is chosen and that set becomes the next active validator set.
