Today, we’re excited to announce that ETHGas has raised a $12M seed round, led by @Polychain, to build Ethereum’s blockspace futures market.
We’ve also received $800M in commitments from leading Ethereum builders to support ETHGas’ marketplace and product development.
Over the past decade, Ethereum has become the most decentralized and economically meaningful settlement layer in crypto.
Its blockspace is scarce and has become the single most high-grade and valuable asset anywhere - more valuable than the market cap of Ether and all the assets on the network.
The next step in its evolution will reimagine how blockspace is allocated on the network.
We’ve split the atom(!) and enter a new era breaking Ethereum blocks down into synthetic 100ms sub-blocks on mainnet. These ‘Realtime Blocks’ were the result of many teams working tirelessly, and independently, to make Ethereum better. This new era, the realtime era, is a significant milestone for Ethereum and the ecosystem at large - let’s break this down 👇👇
Context: ETHGas enables people to buy blockspace in advance, trade it, strip it apart, and generally sequence blocks as they like. Typically, these players (traders/block builders) maximize MEV in the block as that’s well — that’s just what people have done. Not in this case, however.
