Q: What miners supported?
A: Any miner like Claymore Miner, zcash-miner, zogminer, nhequiminer. In order to work with stratum mining software must support official stratum spec zips/draft1.rst at 77-zip-stratum · str4d/zips · GitHub
Q: Is there unlocked version without devfee?
A: Unlocked (without devfee) version is available to big and mid-range miners for 0.75 BTC per license.
I am selling binary builds for any platform (OSX/windows/Linux) with optional source code access for trusted clients. Unlocked version also includes ZEN support.
A: Pool is available for 1.5 BTC with source code.
So if you are big miner and like to mine solo in order to receive your coins only from blockchain, not from 3rd party centralized services you definitely will be interested in it. I am available in ZCash Community Chat.
It’s easy to run, like ether-proxy. You just run it on one of workstation together with zcashd. Then configure miners to use it like a pool. The only difference that you will have reward only after block found.
Actually real possible solution/s rate for solo mining we will see after launch. Solo is possible with any rigs but bigger rigs will reduce your variance. If you can solo mine ethereum you can also solo mine ZCash.
plus my clients
There is no any accounting implemented since it’s personal solution. No way to distinguish from your rigs and clients rigs. Only if you will use separate instances of proxy with different daemons because coins rain to coinbase provided by daemon via GetBlockTemplate.
if your clients are not a bunch of miners with a single GPU/RIG, you can always deploy many proxies with many coin daemons on the same machine, we did this with Ethereum and it worked just great. For starters this is the best thing you will get on the market.
