Sedna: Sharding transactions in multiple concurrent proposer blockchains
Alejandro Ranchal-Pedrosa, Benjamin Marsh, Lefteris Kokoris-Kogias +1
Modern blockchains increasingly adopt multi-proposer (MCP) consensus to remove single-leader bottlenecks and improve censorship resistance. However, MCP alone does not resolve how…
MEV in Multiple Concurrent Proposer Blockchains
Steven Landers, Benjamin Marsh
We analyze maximal extractable value in multiple concurrent proposer blockchains, where multiple blocks become data available before their final execution order is determined. This…
A Time-Bound Signature Scheme for Blockchains
Benjamin Marsh, Paolo Serafino
We introduce a modified Schnorr signature scheme to allow for time-bound signatures for transaction fee auction bidding and smart contract purposes in a blockchain context, ensurin…
The Algorithmic Geometry of Decompression Schedules
Benjamin Marsh
We cast decompression planning as hybrid optimal control with ppO and narcotic depth feasibility, affine tissue ceilings, and convex oversaturation penalties. A rearrangement t…
