Bell Curve
Multiple Concurrent Proposers on Solana and Ethereum | Anatoly & Max
Oct 29, 2024
Anatoly Yakovenko, co-founder of Solana, and Max Resnick, an Ethereum researcher, dive into the intriguing concept of Multiple Concurrent Proposers (MCP) in blockchain. They discuss how MCP can challenge the proposer monopoly in proof-of-stake systems, potentially enhancing efficiency and decentralization. The conversation also touches on the geographic distribution of proposers and trade-offs in blockchain design, ultimately posing the question: is Ethereum's biggest threat Solana or its own Layer 2 solutions?

- Positioning block producers near key information sources reduces transaction latency, enabling decentralized systems to compete speed-wise with centralized exchanges.
Deep dives
Breaking Up the Proposer Monopoly
The concept of a proposer monopoly arises in many blockchains, particularly proof-of-stake systems, where only one party enumerates and organizes transactions, which can result in censorship and higher fees. To counteract this, introducing multiple concurrent proposers allows for diverse transaction inclusion and distribution, enhancing both censorship resistance and competition. This model ensures that transactions are not monopolized by a single proposer, mitigating the risks of extractive behavior, which can harm the overall network and its users. With this change, users can potentially achieve lower fees and faster transaction times, leading to a more equitable and efficient blockchain environment.
