TechFlow news, October 10 — According to the Unichain whitepaper, node operators must stake UNI tokens on the Ethereum mainnet to become validators of the Unichain Virtual Machine (UVN). Unichain tracks staking status via a smart contract that receives notifications of staking and withdrawal operations through a native bridge. Unichain blocks are divided into fixed-length epochs; at the beginning of each epoch, a snapshot of current staking balances is taken, and rewards for each staked token are calculated.
The whitepaper also states that participants can increase a validator's staking weight by staking and voting for that validator. A fixed number of validators with the highest staking weights will constitute the active set, qualifying them to publish attestations and earn designated rewards for the corresponding epoch.
