The ZK rollup debate: Why Bitcoin isn’t there yet

The ZK rollup debate: Why Bitcoin isn’t there yet
The article explains the differences between Ethereum's zk rollups and Bitcoin's limitations in implementing true zk rollups. It states that Bitcoin's architectural constraints make it difficult to accommodate computationally intensive verifiers like Ethereum's zk rollups. Instead, Bitcoin projects like BitVM use SNARK-based compression and optimistic verification to split programs into smaller verifiable chunks. The article also discusses the broader discussion around Bitcoin Layer-2 solutions and the need to focus on trust assumptions rather than just labeling projects as L2. The author emphasizes the importance of education, transparency, and clear definitions to better understand Bitcoin's scalability within its constraints. Achieving true zk rollups in Bitcoin would require a soft fork and the consideration of new opcodes. An open Wiki-style forum is being used to gather preferences and justify views on Bitcoin's future roadmap.
