Hello,
So if I stake GNO on my Node and will receive xDAI as staking reward?
Validators stake GNO to secure the network and earn GNO as consensus rewards. In addition, they can receive xDAI as execution rewards when proposing blocks. More details about rewards can be found in the Gnosis Chain docs.
GNO stays the fixed supply token of 3M
Yes, following GIP-35, the total GNO supply was reduced to 3 million, initially, the tokens were soft-burned and a few months ago, GIP-116 completed the process with an actual on-chain burn.
How is the transaction fee burn implemented on GnosisChain? No burn?
With EIP-1559, a base fee is burned for each transaction. In practice, due to the bridge configuration, these burned fees are redirected to a treasury controlled by kpk (formerly karpatkey), who are managing the GnosisDAO treasury.
When staking GNO on my Node, I cannot simultaneously use it for voting?
Yes, your staked GNO can still be used for governance. Voting power is attributed to the withdrawal address associated with your validator(s).
