Manta's Layer-2 Blockchain Already Plans to Ditch OP Stack for Polygon

The network, which just went live a couple weeks ago as a so-called optimistic rollup – the core underpinning of OP Stack – will now become a “ZK-rollup,” which is what Polygon’s software kit provides.

Coinbase’s Chosen Blockchain Brand Sees Zero Threat from Zero Knowledge

Many Ethereum aficionados have predicted that the most promising layer-2 blockchains would be built not using the OP Stack’s “optimistic rollup” technology – favored by the U.S. crypto exchange Coinbase – but with a different setup known as “ZK rollups,” reliant on "zero-knowledge" cryptography.

What Is Ethereum’s ‘Data Availability' Problem, and Why Does It Matter?

Separate “data availability” layers could reduce congestion on the Ethereum network by making it easier for ancillary “rollup” networks to verify that transactional details exist and are available to download if needed — without actually downloading them. The concept might offer an alternative to Ethereum’s own proposed solution, seen as years away.
