Exciting news coming soon. Devs need a few more weeks to iron out the details. We could expect major changes on the backend to solve all concerns from the community. Total supply, mining reward, etc... So, keep watching
b2n-project devs are currently working on v2.2 upgrade. The release of upgrade is set for Jan 18, 2019. This upgrade will address all of the lingering issues- be it wallet sync or daemon crashing or transactions stuck in mempool.
regards; I downloaded the 2.1 wallet and the blockchain, but if it does not synchronize, it remains in block 183953 (1 month and 5 days ago, any solution?
Probably, you have issues with the connection. Try to ask in the official Discord. I'm sure someone will help you. Also, you always can use remote node to work with the wallet. Please refer to instruction https://youtu.be/sMAzTJMIgJ4
Also, developers now test B2N Web Wallet. So, we can expect the Web Wallet should go live ahead of schedule. There are some previews available at Discord.
is there any spreadsheet with the GPU Card templates and their return values? thank you
No at the moment. Actually, the hashrates are very close to the CryptoNight Light algo, but settings can differ. The SRBMiner's automatic settings are pretty good.
are you using b2n-stak (modified xmr-stak), or another miner like xmrig?
I use SRB Miner. It works perfect - very stable with less setup compared to others. It has an automatic mode which is quite precise and provides the best performance.
