Or say for any coin. Do you have to run the block count through the coin's algorithm to find the block reward? How come the block rewards is not listed in the daemon

It would be really great if I could download the blockchain.

How long does it take to approve someone?  I signed up earlier today and no email confirmation.



Alpha starting tomorrow night hopefully.
891  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN][Pool] HashBros Private Alpha [Multi][Profit Switch][Transparent] on: January 03, 2014, 06:21:32 AM
You should go ahead and approve mine Smiley

I would but there are some final things that need to be worked out. Tomorrow doe.

You're going to want to create some system of hysteresis for profit switching that takes a number of factors into account. For instance, HashCows offen jumps to coins which are *slightly* more profitable than the current coin, only to jump back a minute later with no gains to show for the switch, when it would be more profitable to simply stay on the current coin. Properly filtering this will need to bias the coin choices based on past history. Some other things to consider include:

- Price at multiple exchanges
- Time of exchange confirms (cryptsy can take hours, and end up trading the coins at a much lower rate)
- Average reject rate for users (for instance, FastCoin = high reject rate on my rig)
- Average profitability of the coin over time
- Coin parameters (finishing blocks vs switching now, etc)

Likely scenario would be to score all of these factors as a low-pass filtered average over several time windows, then assign weights to them for each time window and finally weight them against each other. Rather than determining the weight manually, you should consider a system that evaluates different weightings and finds the ideal one.

For instance, imagine we construct min/average/max profitability for each coin for various time windows (say, 20 minutes, hourly, 6 hour, days, etc, based purely on exchange value). Assuming we're using cryptsy, we can look at the average time between transfer and trade to determine a possible variance on price over that time (based on our min value during a time period matching the average trade time for cryptsy). This gives us a reasonable projection of price and variance by the time we get to the exchange. Factor in the historical reject rate for the coin (averaged by users), and perhaps the slope of the coin over a long time window (for instance, doge has been going down for days), and you get a pretty decent score for your coin. More importantly, it's unlikely that a small spike in the data (single bogus trade, etc) is going to cause the system to thrash over to the wrong coin.

Anyway, you get the idea..


brb talking to my finance buddy. but seriously very insightful. I imagined developing some sort of algorithm thats better than the most profitable at the moment but this is something else.

Great discussion going on reddit : http://www.reddit.com/r/litecoinmining/comments/1ua4d6/hashbros_multicoin_pool_with_profit_switch_alpha/

Signed up

How do you handle the work that's already been spent in a round and you jump to the next coin?  Will you finish that block out before jumping?

I haven't given this thought but this is actually a fantastic idea.

I think what we can do when making such a decision is look at the average time it took find a block and see if its worth staying to finish till the next block.

Signed up!  Smiley

Thanks. Also if anyone has any feature requests that may be a bit of a reach we'd love to hear them. Something that you've never seen other pools do.
896  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN][Pool] HashBros Private Alpha [Multi][Profit Switch][Transparent] on: January 03, 2014, 12:06:08 AM
Interesting, subscribed!

Thanks for registering up guys. We've already got 20 sign ups. Let's keep it coming.
897  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN][Pool] HashBros Private Alpha [Multi][Profit Switch][Transparent] on: January 02, 2014, 03:39:45 PM
Site is down?

I'm deploying code regularly which makes the site unresponsive at times. It should be up.

Are you going to be transparent about your switching algorithm?

Right now we are using coinchoose to determine what coin to mine. For the most part its reliable but I have been thinking about developing my own version of coinchoose because it lacks coins. For profit switching its pretty basic to calculate whats profitable to mine. As long as you have an exchange like cryptsy to bounce prices off of. What's hard for most to do is to adapt for new coins. Thankfully we can support new coins in under 15 mins.

If you simply mean the coin that is being mine, it will be displayed 24/7

Hi all. About three weeks ago we announced our private alpha which went very well. We were able to stabilize our platform enough to a point where we are confident in going beta. We are eternally grateful for our early users. With 1200 users registered we're really excited to open up access and registration to blow the hash rate through the roof.

Pool features

Optional Profit Switching - Don't want your coins traded to BTC? Thats fine. We only charge 1% fees for profit switched mining.
Direct Deposit - In the event that you aren't auto trading your coins they will be dispatched to your wallet immediately after a round. Hackers can't steal what doesn't exist.
Not MPOS based - We've written our entire stack from scratch. We don't depend on anyone but ourselves and have much greater feature velocity.
Distributed Pools - Each pool runs on it's own server. This makes scaling effortless and eliminates a single point of failure.
DDOS Protection - Our services are protected by a CDN, making it very difficult to DDOS.
Beautiful UI - Seriously, take a look for yourself. We have also optimized the UI for mobile.
2 Factor Authentication - We support 2 factor auth via Google authenticator. This is used on sign in and for redeeming payouts.
Automated Payouts - You can set your own thresholds, when they're hit you'll be receiving automated payouts.
Incredible Transparency - Every round displays in depth information about each block mined, each user's shares and percentage of work, each deposit post-round, and the sell orders/trades made on cryptsy. It's pretty ridiculous.
Email Security Alerts - Password changed? Payout addresses changed? We'll let you know.
Geographically dispersed web servers - We have web servers in the USA and Europe
Historical coin data - You can check out the historical profitability, network hash rate, exchange rate, and difficulty for all our coins.
FREE API - Right now we offer a free profitability API
Intelligent Profit Switching - We don't just profit switch to the most profitable coin, we take into account market depth and liquidity. We will never profit switch to a coin that we can't sell nearly immediately. This means you will never be waiting for your payouts for days on end.
Rapid coin deployment - It takes us about ~ 10 mins to get a new coin node up. Then we just have to sync the blockchain.
SECURE - Our SQL queries are sanitized (no SQL injection), we use public key authentication on all our servers, and implement 2FA where applicable. SSL is coming once more users start hashing.
Active Developers - Our development repository is nearing 1500 commits.
Open to suggestions - We're already implemented a number of features that you've suggested at www.hashbros.uservoice.com

Upcoming Features
LTC auto trading
Worker notifications
and more I can't recall.

Vision
Our vision is to provide an incredibly transparent, secure, and reliable crypto coin mining service. We want to bring an unprecedented level of professionalism to alt coin mining and thus to crypto.

What are the fees?
1% for using our pools and an additional .5% for auto trading to BTC. Minimum BTC payout is .0005 per BTC fees.

Why beta release
We still have a TON of awesome features to bring and development to do. Parts of the site may not be optimal/missing as they could be under development.
