Charlie LeeEarlier this year, I switched my cellphone provider to Google Fi. Never looked back. It's great but you need an Android phone. ($20 referral credit if anyone wants to check it out: g.co/fi/r/2027KT)
And with Google's Advanced Protection Program, I'm almost unhackable. 😀
Charlie Lee@VitalikButerin@bobbyclee There are indeed some concerns with this attack vector of LN, but there are also a lot of potential solutions like timestops, pre-allocating block spaces, etc. See this message from @roasbeef
Charlie LeeUpdate on Confidential Transactions (CT) by Greg Maxwell: lists.linuxfoundation.org/pipermail/bitc…
Previously CT txns are ~16x size of normal txns. New breakthroughs by Benedikt Bünz and Jonathan Bootle results in only a ~3x size increase. CoinJoin can combine txns to make this negligible!
