episode 359: The Layer-1 Data Availability and Consensus Solution
NB: Since the recording of this podcast LazyLedger changed their name to Celestia.
Celestia is a scalable general-purpose data availability layer for decentralized apps and trust-minimized sidechains. It is a minimal, viable blockchain which does time stamping and block ordering.
Think back to Bitcoin in the early days, before Ethereum. Layer-2 systems were being built on top of Bitcoin and were leveraging Bitcoin’s consensus layer. This is what Celestia is doing, although it is purpose built and scalable for the exact use case. The implementation details are a lot more complex, and the vision is to create a modular pluggable Layer-1 that does nothing but consensus and data availability. It is designed for people who want to create their blockchain without consensus.
The project is yet to be launched, however we had Ismail Khoffi, Co-Founder and CTO, and Mustafa Al-Bassam, Co-Founder and CEO on the show to give us a deep technical overview and vision of Celestia.
Topics covered in this episode:
- Ismail and Mustafa's backgrounds, and how they got into the crypto space
- How Ismail and Mustafa met and created Celestia
