Greetings,
What do you think about implementing Confidential Transactions in extension=
blocks? CT transactions go from extension block to extension block passing=
through normal blocks. It looks the perfect solution:
- Soft fork: old nodes see CT transactions as "sendtoany" transactions
- Safe: if there is a software bug in CT it's impossible to create new coin=
s because the coins move from normal block to normal block as public transa=
ctions
- Legal: Exchanges can use public transactions so regulators can monitor th=
eir activity
- Capacity increase: the CT signature is stored in the extension block, so =
CT transactions increase the maximum number of transactions per block
Regards
