A multi-phased fork, colloquially known as a “spork”, is a mechanism unique to Dash used to safely deploy new features to the network through network-level variables to avoid the risk of unintended network forking during upgrades. It can also be used to disable certain features if a security vulnerability is discovered - see here for a brief introduction to sporks. This documentation describes the meaning of each spork currently existing on the network, and how to check their respective statuses.
Sporks are set using integer values. Many sporks may be set to a particular epoch datetime (number of seconds that have elapsed since January 1, 1970) to specify the time at which they will active. Enabled sporks are set to 0 (seconds until activation). This function is often used to set a spork enable date so far in the future that it is effectively disabled until changed. The following sporks currently exist on the network and serve functions as described below:
Governs the ability of Dash clients to use InstantSend functionality. InstantSend is described in DIP0010 LLMQ-based InstantSend.
If enabled, masternodes will reject blocks containing transactions in conflict with locked but unconfirmed InstantSend transactions.
If enabled, superblocks are verified and issued to pay proposal winners.
Enables the DKG process to create LLMQ quorums. This spork will be turned on once 80% masternodes are upgraded to v0.14, which will enable DKG and DKG-based PoSe.
Enables ChainLocks, a mechanism of preventing the risk to payments introduced by blockchain reorganization events. ChainLocks are described in DIP0008 ChainLocks.
Enables connections between all masternodes in a quorum to optimize the signature recovery process.
Enforces Proof of Service requirements for masternodes to support a minimum protocol version and maintain open ports.
Viewing spork status#
spork show and
spork active commands issued in the debug
window (or from
dash-cli on a masternode) allow you to interact with
sporks. You can open the debug window by selecting Window > Console.
