As layer-2 chains continue to proliferate, some Ethereum developers are pushing rollup tech that takes a new approach to interoperability: “based rollups.”

Sustained demand for Layer 2s could quickly deplete the available blob capacity. The impending Pectra upgrade only kicks the can down the road, Polynomial’s co-founder said.

One of the biggest trends of 2023 among the leading layer-2 projects on Ethereum was the emergence of “blockchain in a box,” where teams encouraged developers to clone their code to spin up new layer 2s. Now, one project in particular, Optimism, appears to be pulling away as the clear leader.

BOB’s aim is to create bridges between itself and layer-1 blockchains like Ethereum, with the ultimate goal of making Bitcoin the center of DeFi.
