I'm curious if you are on the right fork??? The main Block Explorer "
http://explore.thespt.com" is showing 23 connected peers and new blocks coming in approximately every 70 seconds, as designed. There should be no significant delays in confirming blocks.
Again, the coin is not dead, it's just got low interest / transaction volume right now. The core infrastructure is solid, and working great.
Hmmm... Maybe, it's a solo miners generate these blocks. I've checked now again, and still no alive pool for mining spots. Wallet is synced, there are 6 connections to the SPT network, but 5+ SPT still unconfirmed (almost 3 weeks has passed). Wallet ver v2.0.0.2-unk-beta (EXE size is 22120960 bytes). Deleted the database, and will wait it to be downloaded from scratch - maybe this will change something...
Anyway, the coin is now not attractive for mining. The scrypt algo is much more temp and power unefficient, than groestl or lyra2re. Bad decision.
