A new study led by MIT researcher Muriel Médard has revealed that decentralisation is not just a philosophical choice but an inherently efficient design principle, especially in large-scale systems.
Médard, who co-founded the decentralized memory infrastructure firm Optimum, explained that centralized control becomes ineffective as systems grow in complexity, while distributed structures naturally scale better. Her latest tests show this principle in action, with Ethereum networks transmitting data more than six times faster under a decentralized framework.
Speaking at TOKEN2049 in Singapore, Médard stated that “control doesn’t scale,” emphasizing that true observability—and therefore control—diminishes as systems expand. She noted that decentralization’s value lies in efficiency rather than ideology, asserting that central systems fail to function optimally beyond a certain size. Her earlier work at MIT on wireless transmitters demonstrated that distributing functions rather than centralizing them made communication systems significantly more energy-efficient.
Building on that insight, Optimum has now applied the same logic to blockchain infrastructure. In recent tests on Ethereum’s Hoodi testnet, the company’s new communication layer—named mumP2P—spread blocks across the network in roughly 150 milliseconds, around 6.5 times faster than Ethereum’s current Gossipsub protocol. The system, grounded in mathematical models Médard first developed over two decades ago through U.S. military–funded research, focuses on optimizing data transfer, often referred to as the “memory layer” of blockchains.
Médard explained that this memory layer functions similarly to a computer’s operating system by facilitating smoother and more efficient data flow. Inefficiencies in data transfer are among the biggest bottlenecks in blockchain performance today, leading to higher transaction costs and slower confirmations. Optimum’s results suggest that decentralising data-sharing mechanisms could help Ethereum and other blockchains like Solana achieve faster transactions and lower network fees.
Industry figures say the findings represent a significant step forward but caution against overestimating immediate impacts. Kanny Lee, CEO of decentralized exchange protocol SecondSwap, noted that even with a sixfold speed improvement, blockchain still trails traditional financial systems in execution speed. However, he believes the advances signal a shift toward “a more efficient on-chain environment” where market reactions become faster and arbitrage opportunities narrower.
As blockchain infrastructure evolves, the focus may increasingly shift from speed to accessibility. Lee suggested that in future markets, factors like token vesting and access windows will define competitive advantage more than raw latency. Médard’s research underscores a deeper insight: as digital networks grow, decentralization isn’t just sustainable—it’s the only model that truly scales.
