Decentralized Non-custodial
Bitcoin block — live

Play for sats. Nobody holds them.

Decentralized games and prediction markets that settle in Bitcoin. No one ever takes custody of your sats: no company, no server, no operator. A federation of independent nodes decides every result. Build your own games or markets, or join as a node and earn a share of the fees.

The mempool building and the war front

Haul the mempool through a war

Real transactions, a live BTC chart turned into a battlefield, one block per round.

A bomber over the front

Bears vs bulls

The price moves the front. You drive between the armies.

The mempool building

The live chain, right now

Every fee, block and transaction on the map is Bitcoin's.

1 · Stake

100, 500 or 1,000 sats, with other players.

2 · Cross the front

The closer you drive to the price war, the more points.

3 · Deliver

Bring the mempool to the miners' drop-off. The nodes replay every run.

4 · Win sats

From the players who didn't make it, back to your wallet over Lightning.

Prediction markets

Up or down. Every 15 minutes.

The same engine runs markets: pick an outcome, stake sats, and the result, reported by the sources the market names, settles it. Winners are paid from the other side's stakes.
