How to check how much has been mined, and how to prompt when a block has been mined
The OP initially provided the explorer address https://aiascan.com/. It is no different from others similar. I guess at one point it will north of 100 GB of RAM?
55 gb ram used for 5950x 
At this rate there will soon be nothing to launch on )
As the OP states, there will later be a GPU miner, therefore the requirement for large amounts of RAM will become irrelevant. In this part, AIA follows the path of similar projects: initially mining only on CPUs and later moving to GPU/FPGA/ASIC. The only mystery is the mining algorithm. At this rate there will soon be nothing to launch on )
