=== Soft Fork Signaling with Block Version
((("mining and consensus", "changing consensus rules", "signaling and activation")))((("forks", "changing consensus rules", "soft fork activation")))((("soft forks", "activation")))Since soft forks allow unmodified clients to continue to operate within consensus, the mechanism for "activating" a soft fork is through miners signaling readiness: A majority of miners must agree that they are ready and willing to enforce the new consensus rules. To coordinate their actions, there is a signaling mechanism that allows them to show their support for a consensus rule change. This mechanism was introduced with the activation of BIP-34 in March 2013 and replaced by the activation of BIP-9 in July 2016.
