What i mean, that sometimes i get fast first confirmation, but there can be several minutes (like 15 minutes) to get first confirmation.
Just trying to figure out whats behind slow confirmations, and can they be someshow make quicker?
On average a block is found every minute and a half.
But sometimes several blocks are found in a row and sometimes it takes more time, like 15 minutes.
Its the same with bitcoin, on average it is 10 minutes. But sometimes the network is unlucky and it does not find a block for an hour...
You can not control that in any way, it is normal behavior of all decentralized crypto currencyes.
The parameters would be when does the next miner or staker solve a valid block and your transaction is included. The parameter is the block time target, which is set to 91 seconds, but in real life its around 100 seconds.
