Function IsReplayProtectionEnabled

src/validation.cpp:224–234

Command-line argument "-replayprotectionactivationtime= " will cause the node to switch to replay protected SigHash ForkID value when the median timestamp of the previous 11 blocks is greater than or equal to . Defaults to the pre-defined timestamp when not set.

// median timestamp of the previous 11 blocks is greater than or equal to
// <timestamp>. Defaults to the pre-defined timestamp when not set.
