Bitcoin's Hidden Path: A Faster Way for Transactions to Reach Their Destination

The Bitcoin protocol has a hidden path that allows transactions to reach their destination faster.

According to Peter Todd, a Canadian Bitcoin developer and applied cryptographer, there is a difference between transaction validity, propagation, and confirmation.

A transaction can be valid according to the Bitcoin protocol rules, but still not be propagated by most nodes due to local policy settings.

Todd explained that nodes use two-layered validation: consensus rules determine transaction validity, while policy rules (also known as mempool or relay rules) are node-specific filters that decide whether a transaction is accepted and relayed.

Policy rules can be stricter than consensus rules, setting minimum fees, limiting transaction sizes, or filtering out small change transactions.

Todd noted that even if a transaction is valid according to the protocol rules, it can still be rejected by most nodes due to policy settings.

The Slipstream service, developed by the MARA Foundation, provides a direct path for large or non-standard transactions to reach the MARA Pool without going through the public peer-to-peer network.

The service allows users to send transactions directly to the MARA Pool, bypassing the normal relay process and mempool filtering.
