    GPU Mining
    • Solo mining appears to have the best efficiency at the moment. If you have a large enough hash rate, solo mine.
    • Use one cgminer process per GPU to ensure you're doing unique work.

    I have a 2-core GPU. What would be the process for opening a single miner instance for each core? I recall getting rejected blocks on the second core, so likely that it was doing redundant work.

    Getting found share for pool 0! message with no accept or reject message after it all the time. I get nothing as immature category in my transactions like happened on testnet. Is there a problem?

    Same here. No its not normal compared to testnet. Nothing is being accepted as valid mined blocks.

    Stupid question: If we close cgminer before confirmation/accept message we will lost them?

    Yeah that's why I am worried in testnet there was an accept message or reject message right after found share message.

    And nobody can tell us for sure if there is a problem.

    Hi,

    Is the following statement correct and if not a short explanation would be appreciated?

    Successfully sent ticket in PoS mining costs the miner the transaction fee and it doesn't matter if the ticket is ever included in a block and thus eligible for reward.

    Thx

    Btw, on https://wiki.decred.org/Decred_Constitution it is stated that block can have up to 5 tickets with 6% of block reward per ticket. But in the OP you talk about max 20 tickets per block which makes 1.5% of block reward per ticket if the "30% PoS-reward-barrier" is still there. I'm a bit confused here. :)

    @davecgh were we can find a command list for POS? :)

    "Manually purchase your tickets according to the current stake difficulty."

    Like this two command! I cant remember how to check the stake and also how to manual purchase!

    From everything I can see, mining is working correctly. People are finding blocks (currently up to block 382) and cgminer is properly tracking the difficulty changes and new blocks.

    Keep in mind that the current mainnet difficulty is:

    $ dcrctl getnetworkhashps
    2672009949334

    That is ~2.5TH/s whereas testnet only had 21GH/s around the peak. That is like ~119x more hash power out there that you're competing with.

    You can list all commands with dcrctl -l.

    $ dcrctl -l | grep ticket
    ...
    purchaseticket "fromaccount" spendlimit (minconf=1 "ticketaddress" "comment")
    ...

    So, as I left shown there, puchaseticket can be used to purchase tickets. However, remember that if you purchase tickets your wallet has to be online 24/7 for months in order to be available to vote when called.

    I can see the command description plain and well. Deciphering it is another story. How about some real world examples for us?
    Something like
    purchaseticket "Dsaslkdfjxx..." 100(purchase 50 stakes @ 2ea currently. fees makes less? Howso?)(minconf=1(ok what is this?) "ticket address"(I already gave you my account! I want a stake ticket dammit! Why are you asking for a ticket #?) "comment"(no comment wtf?!?))

    Then how do I adjust my fee preference to get higher in the stake order? On the flip side how do I prefer higher fee PoS mining?

    I would say unequivocally yes. This is not testnet anymore. Difficulty is MUCH HIGHER(think 25x harder) and much more hash power is being put to use.
    Code:
    testnet hash rate = 27,572,924,358 or 27Gh/s (highest I saw it get)
    mainnet hash rate = 3,185,783,508,687 or 3,185Gh/s currently

    Why do you suggest to buy tickets manually? So far I have ~ 130 tickets which were purchased automatically during the night for the price 2 +0,05 fee.

    All these tickets are still immature, it seems there is a problem now :(

    I tried to buy them manually, but did not succeed, because wallet don't see my balance and asks for spendable coins. I tried to remove wallet and create back from seed, but it doesn't help.

    Meanwhile wallet continue purchase tickets and add 2 coins to my locked balance. So I have ~ 260 all / locked, and 0 spendable (but wallet can spend them)
