Set Sapling mainnet activation height
In mainnet, block #419200 is expected to appear on October 28, 2018, Zcash's birthday.
In testnet, block #280000 is expected about a week from now. (Current height is ~275249, plus 4032 blocks for a week, plus a little more just to make the number nice.)
These are the activation heights for Sapling in mainnet and testnet, respectively. Protocol version is also changed.
Assets:
change tokeninfo to return "supply" in satoshis
Max description length to 4096
Rewards:
Fix rewardsunlock without giving it a locked txid always gives error
Fix (nonconsensus) allow anybody to unlock only AFTER maxtime
Fix rewards unlock to use mempool
fix could you add a locked_funds value to rewardsinfo?
Fix i deposited 100000 at 20% apr for one day i only got back
100000.01140669 seems like too little for 20% APR
Faucet:
Fix txid with 0x00 at beginning and end required for faucetget txid
(65536 average iterations needed)
Change reduce faucet get to 0.1 coins
Can’t reproduce: it seems that if you re-run faucetget twice in the
same block is when it pegs the cpu to max
Dice:
fix Dice status always returning loss
Wont fix Profit margin for dice plan sounds good. -> use -ac_commission
Always write the empty root down as the best root, since we may roll back
In [`3577de83`](3577de83aa) we started not writing the Sapling empty root down as the "best" anchor because we had changed the encodings and didn't want users who compiled from master to have inconsistent coindb's in the future if the encoding changed again for some reason.
However, if we don't write the empty root down then during rollbacks to Sapling activation we leave the best anchor on disk different from what's in the cache, which will trigger an assertion.
This reverts the change from `3577de83` since we've settled on the encodings.
