Long-Range Attack Protection is a security measure designed to safeguard blockchain networks against potential threats when a significant amount of time has passed since the last consensus checkpoint.In a long-range attack, a malicious actor creates a new blockchain starting from a point far back in the chain’s history. They attempt to outpace the legitimate blockchain, allowing them to control or manipulate the network. This can potentially invalidate transactions and undermine the integrity of the system.To counter this threat, various techniques are implemented. One common approach is through the use of checkpoints or periodically created stable states of the blockchain. These checkpoints help ensure that nodes recognize and adhere to the officially accepted version of the blockchain, thereby making it difficult for attackers to create an alternate version without being detected.Overall, Long-Range Attack Protection enhances the security and resilience of blockchain networks, ensuring that they remain trustworthy and reliable for users and stakeholders.
