Post trigger, account levels will map correctly to share bins, subtracting 1 to account for the 0th element of the shareBinsByLevel array.
Pre-trigger, the legacy mapping will remain in effect.
Post trigger, this change will use all 128 bytes of previous block's signature when
calculating/validating next block's "minter" signature (itself the first 64 bytes of a block signature).
Prior to trigger, current behaviour is to only use first 64 bytes of previous block's
signature, which doesn't encompass transactions signature.
New block sig code should help reduce forking and help improve transactional
security.
Added "newBlockSigHeight" to blockchain.json but initially set to block 999999
pending decision on when to merge, auto-update, go-live, etc.
Any reward leftover from ditributing to legacy QORA holders is reallocated to either:
founders if any online
or
account-level-based reward candidates, if no founders online
We should get pretty close to 100% block reward distribution, barring rounding artifacts.
More documentation and tests.
Removed BlockChain's founderShare as it is calculated in Block on a per-block basis instead.
