{% autocrossref %}
Quorum Commitment
*Added in protocol version 70212 of Dash Core as described by DIP6*
{% endautocrossref %}
The Quorum Commitment special transaction adds the best final commitment from a
Long-Living Masternode Quorum (LLMQ) Distributed Key Generation (DKG) session to
the chain. This special transaction has no inputs and no outputs and thus also
pays no fee.
#### SubTxRegister
{% include helpers/subhead-links.md %}
Since this special transaction pays no fees, it is mandatory by consensus rules
to ensure that miners include it. Exactly one quorum commitment transaction MUST
be included in every block while in the mining phase of the LLMQ process until a
valid commitment is present in a block.
{% autocrossref %}
If a DKG failed or a miner did not receive a final commitment in-time, a null
commitment has to be included in the special transaction payload. A null
commitment must have the `signers` and `validMembers` bitsets set to the
`quorumSize` and all bits set to zero. All other fields must be set to the null
representation of the field’s types.
