YES, you can use wallet_id+workername at this pool. Use walletID+workerID.
Yes and no! The Hashrate in your miner is the actual hashrate. The dashboard shows effective hashrate. If you solve a 10000 share after 5000 you get higher effective hashrate. If you solve it at 13000 its lower than what your miner shows.
Server is in France, but you can mine here from all over the world.
NO! You can not mine directly to exchange wallet, your coins will be lost!
Detached or Orphaned blocks are valid blocks which are not part of the main chain. They can occur naturally when two miners produce blocks at similar times. Read more here: StackExchange.
Difficulty is a measure of how difficult it is to find a hash below a given target.
Mining is probabilistic in nature: if you find a block earlier than you statistically should on average you are lucky if it takes longer, you are unlucky. In a perfect World pool would find a block on 100% luck value. Less then 100% means the pool was lucky. More then 100% means the pool was unlucky.
Share is a possible valid hash for the block. Shares are beings sent by your rigs to the pool to prove their work.
Transaction data is recorded in blocks. New transactions are being processes by miners into new blocks which are added to the end of the blockchain.
It depends on amount of active miners. The more miners work on pool → the more hashrate pool has → the more blocks are found by the pool. However the more miners are active → the less reward you get from each block found.
Proportional (Share-based): Every time a block is found, its reward is split between miners according to the number of shares they submitted.
The estimated payout is a calculated using your percentage of valid shares on the total for current round. This percentage is then applied to the reward of the last block found by the network.
As soon as the block is found, it takes 20 blocks to confirm it, then you will get your reward. This takes about 2 hours (20 blocks of 4 minutes). Please wait a little bit more time. To make it easier to understand block on the "Pool blocks" page need to become green. After that pool is automatically calculating shares and increasing pending balance of all miners taking part in mining.
Since you start to mine your hashrate grows gradually. Please wait. The pool determines your hashrate based on the amount of shares sent by your mining rigs (workers). This value could be a little bit different from reported hasrate (in your mining software).
If you submit lots of invalid shares, your IP will be banned by the pool for a fixed period. Possible reasons for invalid shares can be your hardware getting overworked, you haven't configure properly the variant on your miners, or your difficulty being set too low.
