I remember there being a product a few months ago that had some extraordinary cliams - I will try to find it.

The machine had to be pointed to their pool, and you accessed the miner status page via their website. The miner looked like a couple s5's taped together IIRC. In the end it was assumed this was a long CON, You would essentially be cloud mining. The machines you ran may not do anything more than turn on and connect to the pool.

So I really won't trust any gear that forces you to mine to their pool; or only provides access to the miner via their website.

ASICMINER did the same thing. Water-cooled and claimed ridiculous stats, which it delivered for one random tester on youtube, but it soon "broke." You managed everything through their website, there was no local management.

Appreciate the info.
Whats the best way to read all the outgoing packets to ensure it's only sent to the selected pool?

Just use Wireshark and watch all of the traffic coming out of the machine

To be 100% sure,

1) Have device in hand

2) Mine to your own address (the manufacturer does not know) at a your choice of pool

3) Read all outgoing packets and ensure it's only sent to the selected pool. If there are packets sent to unknown places, the manufacturer could be receiving info on your pool/address and send some of their own hash to the same pool/address..

4) If hash rate at pool is up to spec, it can be considered verified.

Sorry still lacking a lot of knowledge - What do you mean by this?? Where can this be found generally?

There is a new and efficient SHA-256 ASIC launching soon and the Octominer team will go to verify the existence and performance of said ASIC to see if it performs as promised.

Is there any way to fake an ASICs hashrate? For example if they run it on their own pool where they have modified some settings to spoof the hashrate or something similar.

How to make 100% sure that the miner is actually hashing at the shown hashrate?
