The current block is still at 838 534 although I've certainly found 20 blocks.
The block 838 534 WAS (!) a deadlock block.Look at this log. It is my former attempt to mining AGRI :
CheckWork() : new proof-of-work block found

And the same with any other freshly mined block. Any new mined 838 535 block was rejected by network because it has "nBits below minimum work" and blockchain grow was impossible. Really it is because the mandatory target of this block has to be nBits=1c8659e4 (you can see it in log above) which mantissa 8659e4 is negative. It is because the retargeting algorithm of AGRI coin calculates negative target of the next block in some rare conditions. If this happens the last block became really LAST and the next block will newer accepted by network. Blockchain appears in deadlock.
But it is easy to cure blockchain and I did it few days ago. I sent two new blocks - the alternative 838 534 block and the next 838 535 block. After that the old deadlock 838 534 block became orphan. You can see now in blockexplorer https://prohashing.com/explorer/Agrinovuscoin/ that block 838 533 has date
Sunday, March 10, 2019 5:19:52 AM
and the next 838 534 block has date two months later
Wednesday, May 15, 2019 9:26:21 PM
And it is the day of becoming sick and the day of curation of AGRI coin network.
For the history now orphaned deadlock block has this attributes :
Block 838,534

Conclusion: AGRI blockchain was cured and now works.
P.S. I am not a dev of AGRI
Keep Calm and
