Episode notes
MCP Reduces Leader Monopoly But BAM Still Matters
- Multiple Concurrent Proposers (MCP) stitches simultaneous blocks from many producers and orders by priority fee to reduce proposer monopoly.
- MCP changes builder dynamics but BAM still offers privacy, verifiability, and ways to influence ordering.
Bootstrap BAM By Hitting A Practical Stake Threshold
- Focus on reaching a practical stake threshold to prove value before expecting universal adoption.
- Lucas views ~25% stake as the bootstrap floor and 50–90% as a solid adoption range for app confidence.
Open Verifiability Beats Fragmented Black Boxes
- Jito prioritizes privacy, verifiability, and consistency to avoid fragmented black-box builders.
- They plan to open source BAM so others can experiment while keeping the system auditable.
