 ==Specification==
 
+Each soft fork deployment is specified by the following parameters (further elaborated below):
+
+# The '''bit''' determines which bit in the nVersion field of the block is to be used to signal the soft fork lock-in and activation.
+# The '''threshold''' specifies how many blocks within a single retarget period (2016 blocks) must have the bit set before we lock in the deployment.
+# The '''deploytime''' specifies a time at which the bit starts counting towards lock-in.
+# The '''timeout''' specifies a time at which the deployment is considered failed. If the median time of a block >= timeout and the soft fork has not yet locked in (including this block's bit state), the deployment is considered failed on all descendants of the block.
