S15 E19: Alexei Zamyatin on Build on Bitcoin and Layer 2s
Alexei Zamyatin is an academic cryptographer who works on the Build on Bitcoin projects. His approach to scaling Bitcoin with second layers involves some unconventional methods, which he describes in this interview.
Zero Knowledge Proofs and Rollups (00:01:21) Discussion of the development of layer two solutions, including zero knowledge proofs and rollups.
Defining BitVM Rollups (00:01:58) Explanation of the debate surrounding the definition of zk rollups and the introduction of the new category of BitVM rollups.
Citrea's Approach (00:04:41) Analysis of Citrea's zk optimized BitVM rollup and its approach to sidechains and rollups.
Zero Knowledge Proofs and Rollups Explained (00:05:26) Explanation of the concepts of zero knowledge proofs and rollups in the context of layer two solutions.
Comparison of Rollups and Sidechains (00:12:41) Comparison of sidechains and zk rollups, discussing their differences and promises.
The Vision of Build on Bitcoin (00:18:48) Discussion of the problems to be solved in the development of layer two solutions and the vision of the Build on Bitcoin project.
EVM: The easiest way to build decentralized applications (00:22:54) Alexei Zamyatin advocates for the ease of building decentralized applications using EVM, while pointing out to the challenges of building infrastructure from scratch.
Liquidity and Stablecoins on Rollups (00:23:53) The challenges of bringing stablecoins onto rollups and the dependency on centralized parties for stablecoin provision.
Bootstrapping BOB as an ETH Rollup (00:25:47) Alexei xplains the decision to bootstrap BOB as an ETH rollup, inheriting Ethereum security and bridging assets.
