I see your block explorer but I don't see POS blocks...
https://chainz.cryptoid.info/arg/No proof-of-stake here, only pow??
Do you planning to using POS with new update of wallet, like TAJCoin - pow/pos.
https://chainz.cryptoid.info/taj/It can open the way to do master nodes, like DASH,
without need to invest hash rate and computing power,
electrucal and hardware supply and energy
for maintain the liquidity of this coin.
Also you can do regular optimization of blockchain through hard fork to
do optimization of blockchain height for fast syncronization for each user.
Just parsing blockchain, and generating all coins for each unique address,
according the summary unspent outputs,
to save holders coins and pack only 1 transaction for each user (many transactions for all) in 1 block.
No need transactions history and long blockchain in this case. Fast synchronize.
Mining POW/POS can be continued from last block of the hard fork.
(to do optimization you can set high difficulty for mining last block of the old blockchain).
Optimization and check the blockchains can be realized on each node
to be constanly after this (have constant hash for all blocks).
Best regards.
