Peter Todd Joins MARA to Lead Private queue of pending transactions Slipstream

What happened

Peter Todd has joined the MARA Foundation as lead maintainer of Slipstream, the miner’s private Bitcoin mempool service. Announced by the foundation on Thursday, the new role will see Todd responsible for developing and running the service.

It was useful after hackers exploited Coldcard hardware wallets in July, stealing over $115 million in user funds. Because transactions sent through Slipstream stay private until they’re confirmed in a block, the service helps to keep key information hidden before confirmation — protecting exposure of their public keys.

Slipstream lets users send bitcoin transactions straight to MARA Pool, the company’s mining pool, without going through Bitcoin’s public peer-to-peer (machines connecting directly to each other, with no server in between) network. MARA’s Slipstream first drew attention in 2024 for publishing large Ordinals inscriptions.
