New opcodes will be enabled for better multisig capabilities. Kindly refer to the whitepaper for the details.
All the old coins are valid and will always be valid.
Old wallet files are forward compatible.
Once the network adopts the fork, the old nodes:
- won't be able to mine new blocks;
- should still be able to sync, send and receive transactions for the time being, but can no longer reliably check whether they're on the proper chain.
Would you please explain the fork.
Why are you forking?
What happens to the millions of coins in the older wallets?
Reason i ask, is i still hold a lot of coin scattered over about 15-20 wallets, mainly 0.8 and 0.9.1, ( a couple might be 0.9.2)and see no reason to upgrade....
