Celo, which is ditching its standalone blockchain in favor of a new "layer-2" network atop Ethereum, had originally signaled plans to rely on Optimism's OP Stack, a similar customizable kit to Polygon's but using Optimism’s “optimistic” technology.
Leading rollup operators are criticized for using "centralized sequencers" to package transactions and pass them down to Ethereum, but the real risks may lie elsewhere.
The U.S. crypto exchange’s ‘Base Neutrality Principles’ are a series of guidelines aimed at maintaining a decentralized and neutral blockchain, according to a blog post.
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.
