The Ethereum co-founder Vitalik Buterin has recently made two proposals during a developer video conference to reduce transaction costs when using ZK-Rollups technology.
The solutions involve the use of files with a large amount of binary data, as explained by lead developer Tim Beiko. It’s “a bit like a mini chunk of shard data,” he added.
According to him, the first option requires minimal changes to support “execution layer” Ethereum clients. The second approach involves more “plumbing” but brings the network closer to “something compatible with full sharding,” Beiko said.
“Some proposals to add ‘blob-carrying transactions’ in a near-future hard fork, bringing higher scalability to rollups before full sharding is complete,” Buterin has on the developer’s tweet about the first proposal.
In the description of the solutions, he has confirmed that in the short to medium term, ZK-Rollups looks like the only trustless solution for scaling Ethereum.
