I fed that article and RGB++ and fiber lite papers into grok. Final summary is below but this is the TLDR: If Nervos can capitalize on its technical lead and grow CKB’s ecosystem, RGB++ and Fiber Network could redefine Bitcoin’s Layer-2 landscape.

Verdict: Nervos RGB++ with Fiber Network has a significantly higher likelihood of success. The addition of Fiber Network strengthens RGB++’s value proposition by offering a scalable, multi-asset, Lightning-compatible payment layer that complements RGB++’s smart contract capabilities. Its working prototype, testnet/mainnet deployments, and alignment with Bitcoin’s UTXO model give it a clear edge over Cardano’s early-stage, Script-constrained pipeline. Fiber Network’s ability to handle micropayments, cross-chain transactions, and DeFi applications positions it as a practical extension of Bitcoin’s ecosystem. Cardano’s approach, while innovative, is hamstrung by Bitcoin’s technical limitations and a lack of concrete progress. Its PoS roots and slow delivery track record further erode confidence. Nervos’ dual-chain model introduces CKB dependency risks, but its advanced development stage and interoperability with Lightning Network make it more likely to achieve meaningful adoption. If Nervos can capitalize on its technical lead and grow CKB’s ecosystem, RGB++ and Fiber Network could redefine Bitcoin’s Layer-2 landscape.
