TFTC: A Bitcoin Podcast
Tales from the Crypt #64: Carl Dong
- Carl's path into Bitcoin through high school teacher recommendation, dogecoin mining, work at 21 and Blockstream, and current role at Chaincode Labs on reproducible builds.
- Reproducible builds and Guix containers as a solution to reduce trusted binaries in the Bitcoin build chain and prevent supply-chain attacks via compromised compilers.
- Modularity of Bitcoin Core through Russell Yanofsky's work to separate wallet, GUI, and node into distinct processes, enabling better governance and parallel innovation.
- Responsible disclosure practices for Bitcoin vulnerabilities differ from centralized systems; anonymity and careful coordination protect both researchers and users given the monetary value at stake.
- Security vulnerabilities in hardware (Intel Management Engine, UEFI firmware) operate below kernel level, creating risks that open-source hardware like Raptor Engineering aims to address.
- Rust Bitcoin as a memory-safe alternative implementation enabling future modularity; multisig solutions like Casa and Blockstream Green as more practical security models than single-key custody.
