An improved blockchain is described herein in which a user burn transaction can be used to increase the probability that another node is selected as a leader. For example, a node can submit a user burn transaction that references a block commit submitted by another node, and may indicate an amount of cryptocurrency being burned in the user burn transaction. The amount of cryptocurrency being burned in the user burn transaction can be summed with the amount of cryptocurrency burned in the block commit referenced by the user burn transaction to determine the probability that the node that submitted the block commit is selected as a leader. While the node that submitted the user burn transaction cannot be selected as a leader, the node that submitted the user burn transaction can share in a portion of the block reward awarded to the node selected as the leader.
