Veteran Bitcoin developer Peter Todd has joined the MARA Foundation as the lead maintainer of Slipstream, a system that allows users to submit Bitcoin transactions privately, without immediately broadcasting them to the public network. This helps keep transactions confidential until they are confirmed in a block.

Why does this matter? Private transaction submission can be useful for:
• Transactions rejected by standard relay policies
• Security-sensitive transactions
• Specialized Bitcoin research
• Reducing information leaks before confirmation

Slipstream has been used for many non-standard and unusual Bitcoin transactions. Peter Todd has extensive experience in this field, having contributed to Bitcoin Core, developed Replace-by-Fee and OpenTimestamps, and researched transaction relay and the mempool.

It is important to note that Slipstream does not create a second Bitcoin network or change Bitcoin’s consensus rules. It only changes how transactions reach miners before confirmation, which could bring significant changes to Bitcoin infrastructure.
