Decred

Decred (DCR) is a cryptocurrency secured by both miners and stakeholders, who also vote on its rules and treasury.

Decred launched on 8 February 2016. Like Bitcoin it has a supply limit of about 21 million coins, and about 17.63 million DCR existed on 1 October 2026. Blocks come roughly every five minutes.

Security is shared. Miners produce blocks with proof of work, and holders who lock DCR in 'tickets' vote to approve each block. Since August 2023 the block reward goes 1% to miners, 89% to ticket voters and 10% to the project treasury. A ticket is picked at random to vote, usually within about 142 days; if it misses or expires, the locked DCR is returned without a reward.

Ticket holders also decide how Decred changes. They vote on consensus rule changes, such as the 2023 switch to the BLAKE3 hashing algorithm, and on proposals funded from the treasury, which held about 881,000 DCR on 1 October 2026.

At launch 8% of the supply was premined: 4% went to the founding company and developers to cover start-up costs, and 4% was given away in an airdrop to 2,972 participants. The software is open source.
