TFTC: A Bitcoin Podcast
Tales from the Crypt #98: Carla Kirk-Cohen
- Carla's journey to Bitcoin through studying computer science and economics in South Africa, leading to her role at exchange Luno and subsequent work on Lightning Network integration.
- Luno's production Lightning implementation as the first custodial exchange to integrate LN for sends, receives, merchant solutions, and wallet functionality.
- Channel management challenges in Lightning routing nodes, including liquidity balancing, automated rebalancing ("looping"), and the need for better tooling to make node operation economically viable.
- Privacy gains from Lightning Network transactions through onion routing and settlement opacity, contrasting with the public ledger trade-off.
- Emerging use cases enabled by Lightning: micropayments, streaming content delivery, refund mechanisms via "hodl invoices," and payment flows impossible on-chain.
- Developer onboarding into Bitcoin and Lightning through Chaincode Labs' 12-week residency, GitHub contributions, and open-source educational resources now available to the broader community.
