ZK Rollup

ZKsync Era still matters in 2026, but not for exactly the same reason it did during its earlier growth phase. At launch and during its first major adoption wave, the case for ZKsync Era was simple enough: it was one of the most ambitious attempts to bring zero-knowledge rollup technology into a general-purpose Ethereum environment. That basic story is still true, but by 2026 it is no longer enough on its own. The rollup market is more crowded, user expectations…

Starknet still deserves attention in 2026, but the reason is more nuanced than it used to be. For a long time, Starknet was mainly discussed as the ambitious Cairo-based zk-rollup that felt more experimental than mainstream. That framing is no longer enough. The network now has enough real activity, enough ecosystem weight, and a clearer rollup maturity profile that it has to be judged as a production Ethereum layer 2 rather than as a promising technical side project. At the…

Mantle says it is transitioning to use Ethereum blobs as its primary data availability layer, framing the move as a milestone toward a full Ethereum ZK rollup architecture. What “Using Ethereum Blobs for DA” Actually Changes Data availability is the guarantee that the raw transaction data needed to reconstruct the chain is publicly accessible. When DA is on Ethereum blobs, the chain’s transaction data is posted to Ethereum’s blob space rather than relying on an external DA layer for primary…
