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…
Pulsar Consensus
Samer Afach, Benjamin Marsh, Enrico Rubboli
In this paper, we informally introduce the Pulsar proof of stake consensus paper and discuss the relevant design decisions and considerations. The Pulsar protocol we propose is des…
