"Onchain privacy is like nuclear physics. There is no doubt that--only with privacy--blockchains can only reach their full potential of onboarding people and businesses globally to permissionless finance. At the same time there is a catastrophic risk if onchain privacy is not done responsibly. The onchain privacy trilemma captures the core contention which I will be discussing at the DC Privacy Summit tomorrow. Tune into the live stream"

"On the recent attacks on TEEs: X. Facts on the attacks named WireTap and Battering RAM for those outside of the security industry: - The attacks target Intel SGX and AMD SEV-SNP but do not directly apply to Intel TDX. - The attacks require physical access to the machine requiring installation of a memory interposer. - Both Intel and AMD stated that the attacks were outside of the designed threat model for the targeted processor i.e. this won't be fixed. Should you be concerned about services that still utilize Intel SGX or AMD SEV-SNP If the physical host of the machine cannot be trusted"

"To build performant decentralized chains we need to ditch gossip protocols. 150ms vs. 1s latency improvement for Ethereum is just a start. mumP2P will be plug-and-play for all chains. Take a look at mumP2P if you are building a decentralized chain"

"Onchain privacy = Nuclear physics Onchain privacy will influence how the world evolves for the next century just like nuclear physics did for the last century. Onchain privacy can empower individuals and be positive sum like nuclear energy or it can empower nation states like nuclear weapons. One major difference is that those building onchain privacy today has a significant sway in the eventual outcome which is something that the nuclear physicists didn't really have. Onchain privacy can make crypto better for human coordination"
