I thought perhaps the reward estimate might have been off at the time, but I've been following the recent estimates posted on the stats page and the subsequent generation rewards in the block chain and they indeed do track properly. I then considered the possibility that we very quickly found the next block after the one deemed to be profitable -- before being able to switch to another coin, but there was a 66 second gap between the two blocks being found, so why didn't we switch to another coin? What happened? At 193,881 doge reward, the profitability for that block would have fallen below even that of litecoin, which always has sufficient exchange volume, so how is it that we were still allocating our resources to doge under those circumstances?
These small doge blocks are just issues that need tweaking (slightly faster response time). The only times I've seen this happen are in special circumstances (where we didn't intend to mine this block, it just happened). When I've seen it, we start mining a high value block (say 700k or so), and between the time we start mining, and the time we check profitability again (can take 10+ seconds due to exchange pricing delays, block processing cpu spikes, etc), someone already mined the high-value block, and we mined a small block immediately after it. I've also seen it happen (not on doge, but on luckycoin), where we will notice the block value change, tell miners to switch, and have some miners (especially on very high intensity) still submit shares 2-3 seconds after being requested to switch. When these shares come in, we still process them for a bit (until that coin's block changes), and if someone submits a valid block for a coin we just stopped mining, we'll still submit it to the network (why the hell not!), and can get smaller block rewards.
In the first of the cases, we can fix it by watching closer (which just needs some tweaks), the second case is just a matter of a few seconds of jump time between coins, which gets solved (slightly) with more endpoints (lower latency).
1. The reward of each block is known as it is mined, therefore it is not rando reward and we are ideally only mining the high reward blocks.
2. What I suspect happened is that a high reward block was solved just before Wafflepool did, and I believe that currently Wafflepool has their minimum shift time for one coin to 9 minutes - Unfortunately in some cases that means that a dogecoin 800k reward block is found within 30seconds leaving us with 8 mins 30 seconds mining say a 200k reward block, which is obviously not as good.
1) Correct.
2) Close, but on a much smaller timescale (check above), we switch as fast as possible, but that is sometimes upwards of 20-30 seconds.
Is it eu.wafflepool.com ? I could already take it into my pool list, then it would switch as soon as it is online.
Not up yet, and haven't 100% decided on endpoint. I'll make some posts when they're up (and some notifications on the site). I _think_ that will be the correct endpoint, but I don't want your miner switching over as I'm testing it
Tagcoin should be re-enable, looks like their blockchain problems are fixed and they are profitable right now
Checking on it now, if everything looks good, I'll re-enable.
