Celestia, a layer-1 data availability network, has announced a technical roadmap aimed at significantly scaling its block size to 1 gigabyte, as detailed in a September 5 blog post. This strategic move is designed to enhance data throughput for Celestia’s rollup ecosystem, which involves bundling transaction data into blocks for more efficient processing.
The roadmap's central objective is to achieve this substantial increase in block size, thereby boosting the network’s transaction processing capabilities. By achieving 1-gigabyte blocks, {Celestia} (CELT) plans to surpass Visa’s transaction processing capacity, which handles approximately 24,000 transactions per second (TPS). This scaling effort aligns with a broader industry trend towards improving blockchain scalability, reducing transaction costs, and optimizing data storage and retrieval.
Celestia’s expansion into larger block sizes places it in direct competition with other data availability protocols, such as EigenDA and Avail, as well as Ethereum’s mainnet. EigenDA recently collaborated with cloud platform Conduit to temporarily boost its block size from 2 megabytes to 16 megabytes. This initiative aims to reduce operational costs for layer-2 scaling solutions by a factor of eight.
Ethereum's recent Dencun upgrade introduced “blobs,” which are off-chain data storage solutions intended to lower costs for layer-2 networks like Arbitrum and Base by minimizing on-chain data requirements.
