Now BGX is a sidechain Ethereum, but a consensus like Stellar. In order to become a node in the sidechain, you will need to have DEC (BGX) tokens on the Ethereum network. They will be frozen while you support the node, but will return to you if you decide to stop.
The node will earn a certain commission on each sidechain transaction. How can he sell the received tokens?
