Long Range Attack in Proof of Stake (PoS) Blockchains

Definition: A long range attack is an attack on the consensus model of a proof of stake blockchain. A block producer (or validator) tries to create an alternative chain starting from a long ago created common block. The long range into the past is necessary to circumvent possible penalties for forking. Long range attacks are explained mostly in conjunction with proof of stake, since this problem is prevalent here and closely related to the nothing at stake problem.
