Greedy-Mine: A Profitable Mining Attack Strategy in Bitcoin-NG

Algorithm 3

Greedy-Mine strategy when the greedy pool finds a keyblock.

(1)	On Greedy pool finds a keyblock
(2)
(3)	if then
(4)
(5)
(6)	else if then
(7)	if  and then
(8)
(9)	else if  or then
(10)	Competition ends
(11)	Mine at the head of the greedy branch.
