Just over two weeks after Ethereum’s successful Dencun upgrade introduced EIP-4844 or “proto-dunk sharding” to reduce Layer 2 gas fees, co-founder Vitalik Buterin announced the next important step, i.e. validating a conservative version of the Blob data. Data Availability Sampling (DAS) called PeerDAS.
Buterin said that with the activation of BLOB completed, “scaling Ethereum is no longer a ‘zero-to-one’ problem, but a ‘one-to-N’ problem.” Validating his blobs using PeerDAS paves the way for introducing additional scaling solutions into the protocol.
The ultimate goal is to enable full data availability sampling, with up to 16 MB of data available per slot. However, this is a gradual process and the capacity of his blobs increases step by step behind the scenes without any interruption to users or applications.
In the meantime, the Dencun team will work on optimizing the Layer 2 platform to maximize usage of the newly available BLOB data space. Since integrating EIP-4844, several Ethereum L2s have already seen significant reductions in gas fees.
With BLOB validation next on the roadmap, Ethereum is taking another important step towards sustainable scaling and widespread adoption through lower transaction costs.
