The article focuses on advancements in the blockchain space, particularly around appchains and rollups. It highlights the issue of underutilized blobs being submitted to data availability (DA) layers, which not only wastes space but also increases costs. As appchains expand, they often face limitations on Layer 1 (L1) block sizes, leading to inefficiencies. The proposed solution is Shared Blob Compression, which enables these appchains to combine their data into a single "super blob." This method promises to increase transaction frequency to DA layers, make better use of available blob space, and reduce the risk of exhausting L1 blob slots. The piece also explains the role of Gateways in processing user transactions. Users interact with a remote procedure call (RPC) without realizing they are using a rollup. The RPC sends the transaction to a Gateway, which can provide preconfirmations, ensuring quick feedback on transaction acceptance. This process enhances the user experience by making transactions feel almost instantaneous. Additionally, the article touches on the evolution of based rollups, emphasizing their decentralized nature. Unlike traditional Ethereum rollups with centralized sequencers, based rollups allow anyone to build blocks. This shift in control could change how transactions are ordered, impacting the potential for making money through miner extractable value (MEV). Spire Labs is spearheading this innovation, having raised $7 million to develop the Based Stack, a new generation of rollups, with backing from several notable investors and venture capital firms.
