Decred (DCR)

Two consensus methods are joined in one network: miners produce blocks, but ticket-holders who have locked coins confirm them. A ticket is bought with DCR and returns to its owner after the vote along with a reward. The hybrid was meant as protection against what happened to Bitcoin in its governance disputes — changes are decided by on-chain voting, and part of the issuance goes to a treasury that funds development. Decred is known for mature governance and a small, long-standing community.
