Bitcoin’s lack of native programmability, coupled with advancements in zero knowledge cryptography, has led to rollups being explored as a substitute for an execution layer. Citrea’s approach involves using Bitcoin as a data availability & settlement layer for their zero knowledge rollup. These rollups not only lower transaction costs, but they also enable smart contracts to use Bitcoin’s L1 security and further incentivise miners to secure the chain despite halving rewards. In order to inherit Bitcoin’s security, zk proofs are inscribed in Bitcoin blocks.

Topics discussed in this episode:
- Orkun’s background
- Inscriptions, BitVM and zk rollups on Bitcoin
- Optimistic bridging
- Sequencer
- Programmability solutions on Bitcoin
- BitVM development
- Citrea ecosystem development
- cBTC vs. custodial wrapped BTC
- There is no second best!
- PoW, halving block rewards and how rollups incentivise miners
- Citrea’s efficiency & fee reduction
- Bitcoin as an inflation hedge
