Long-Living Masternode QuorumLong-Living Masternode Quorum - Long-Living Masternode Quorums (LLMQs) are a Dash innovation that enable masternodes to perform threshold signing of consensus-related messages (e.g. InstantSend transactions). LLMQs provide a more scalable, general use quorum system than the ephemeral ones used prior to Dash Core version 0.14.
ChainLocksChainLocks - ChainLocks are a feature enabling near instant consensus on the valid chain. ChainLocks use Long-Living Masternode Quroums to mitigate 51 percent attacks and reduce uncertainty when receiving funds.
