What are the differences?
Security, privacy, 5% interest, atomic swaps.
dPoW security layer to leverage BTC hashrate to secure KMD (and its assetchains)
Hybrid mining of notary nodes and miners to make 51% attacks more difficult to conduct, due to the partitioning of mining power and the effective increase of notary mining power as overall hashrate increases. Basically an attacker's hashrate is used against them, the more hashrate they use to attack with, the more the effective notary mining hashrate becomes. If you cant achieve 51% hashrate, it is not possible to conduct a 51% attack.
zero footprint 5% APR, where all addresses are accruing interest at the same time and thousands can claim it at any given block (limited by block capacity) all without taking any extra space in the blockchain. No staking is required to collect interest and no other privacy coin is also having 5% interest.
JUMBLR that tumbles the zcash meta data layer making what little privacy leakage zcash has eliminated
runtime creation of forks via -ac_name=ASSETCHAIN parameter
dozens of active assetchains secured by dPoW using on-demand blocks. Since the blockchain security is provided by dPoW, it is not needed to accumulate difficulty with new blocks to secure the chain. this eliminates blocks without any transaction other than the mining and the blocks are created only with actual usage.
above is what has been working for many months. The various features combine to create an efficient ecosystem. Currently in final testing is:
barterDEX reference currency for atomic swaps with almost 100 other coins, for coins with electrum servers, SPV mode can be used for atomic swaps without running the coin daemon locally
dICO platform that combines the above features into a decentralized ICO process
In development for the KMD platform are:
smart contracts, interfacing to Lightning Network, decentralized betting and shuffling and the ability for realtime for money games to be supported.
Also a few other things I am not allowed to talk about publicly yet. Probably some things I forgot to list.
