- Few more ideas implemented and will be tested for review in upcoming technology preview.
-
###3.4
- DAG/MINIDAG with blocks flowing every second
- Mining Decentralization.No more mining pools, daily 100000 reward blocks, no need for pools and thus no attacks
- Erasure coded blocks, lower bandwidth requirements, very low propagation time. Tested with upto 20 MB blocks.
- DERO Simulator for faster Development cycle
- Gas Support implemented ( both storage gas/compute gas)
- Implemented gas estimation
- DVM simulator to test all edge cases for SC dev, see dvm/simulator_test.go to see it in action for lotter SC.
###3.3
