Episode notes
Finding Satoshi Could Be Two People
- The Finding Satoshi documentary argues Satoshi may have been a duo: Hal Finney (engineering) and Len Sassaman (white paper/academic work).
- Matt Walsh and Nic Carter highlight PGP workplace ties, a rare cited Belgian conference paper, and moving interviews with both men's widows that strengthen the duo theory.
Stylometry Might Mislead Satoshi Investigations
- Stylometry may be unreliable for de-anonymizing Satoshi because contemporaries knew the technique and could deliberately obfuscate writing styles.
- Nic Carter notes Len and Hal were aware of stylometry and could have intentionally altered writing to avoid later attribution.
KelpDAO Bridge Exploit Cascaded Into Aave Bad Debt
- KelpDAO was exploited via LayerZero bridging, allowing attackers to mint tokens, deposit them on Aave and withdraw real assets, creating bad debt for Aave.
- Arbitrum froze ~$70M of ETH to recover funds, sparking debate about decentralization versus emergency freezes.
