Grey Mirror #1—Tadge Dryja, Digital Currency Initiative: uTreeXO and Bootstrapping Bitcoin Upgrades
MIT Media Lab’s Digital Currency Initiative is starting a new podcast on technology, society, and ethics called Grey Mirror (Soundcloud, Youtube, iTunes). Unlike Black Mirror, which only explores technology’s negative impacts on society, Grey Mirror explores technology’s negative and positive impacts on society.
In today’s 1st episode, Rhys Lindmark interviews Tadge Dryja, a research scientist at DCI who co-invented the Lightning Network. We chat about his current research (uTreeXO, a dynamic accumulator for Bitcoin state) and discuss non-fork ways to bootstrap upgrades to a network (a bridge node for uTreeXO). For more on accumulators, see:
- Bitcoin Core Dev discussion on accumulators
- Pieter Wuille’s accumulator overview for Cryptocurrency Research Review #1
- Benedikt Bunz, Dan Boneh, and Benjamin Fisch’s recent research on RSA accumulators.
