First ever RIC transaction with MultiSig address
(with "T" prefix (equivalent to "3" Bitcoin addresses), it seems that clo1 agreed to use my suggested prefixes) mined in
966545 
! 20 RIC were sent to TWaXpZTMJoFAGMzFj5r4uwq7S7kWirtZkp, and another "T" address was used as change. Riecoin is becoming ready for the next decade!
This is so new that Cryptoid is not even showing the addresses correctly, with a "3" as prefix instead of "T".
This also means that rieMiner would already be 0.16.3 ready. Next step will be to test if I can send
from such addresses.
News about transactions not broadcasting using 0.16.3 can be found in
this topic (also read the end of previous page).
For now, if you want to create transactions with 0.16.3 and get them confirmed, add the IGJ's 78.83.27.28 node, and wait that I find a block (will take about 1/2 day on average currently)... Or maybe other miners can start mining using a 0.16.3 wallet, I am the only one for now!
After fixing this (if possible), we should start to distribute some Deb64 and Win64 binaries to start the transition.
Edit: hmmm, weird... It seems that it is impossible to spend the coins from "T" addresses... The Debug.log says "CommitTransaction(): Transaction cannot be broadcast immediately, no-witness-yet", so it is not willing to broadcast...
