Hi everyone,
I've got few sample chips from bitfury and made microscope photos of these.

PS. Still want to get BFL sample chip. Could anyone in direct contact with them help me with this?

Slightly damaged chip was extracted from live mining rig (thanks for the chip goes to our fellow forum member needbmw):

PS. I am open to make photos of any other custom bitcoin chips. Bitfury is next on the train. BFL, anyone?

Hello there ASIC manufacturers,

I am doing a blog with microscope photos of various microchips: http://zeptobars.ru/
I would be very interested to publish photo of you chip with active link to your website, and this might prove to someone that you actually have custom ASIC.
I can confirm whether it looks like actual bitcoin miner, and it's manufacturing technology.

All I need from you is send me 1x your custom chip (it might be preproduction/engineering batch). Please drop me a message to michail@zeptobars.ru

PS. Why writing here? Because I couldn't find Avalon email contacts, and I am pretty sure all custom ASIC manufacturers are watching this forum :-D

We'll get something like this:

As far as I see, the basic idea of mining, is that we get piece of data, where we need to try all variants of 4 specific bytes = 2^32 variants, we hash this data using SHA256 and if we get value meeting our difficulty requirements we "win"(?)

I wonder how does this work on lower level:

1) How it's made that different clients does not work on the same variants?
2) How it is prevented that client who found solution would "steal" 50BTC, instead of submitting solution to the pool server?
3) How does pool software process this solution to get 50BTC and notify whole system that everyone (including other pools & individuals) need to work on next block?
4) Is that correct that all fees associated with newly generated solution are "payed" to the owner of this solution in the nearest minutes after it's generation?

Sorry for dumb questions, and thanks :-)

Sorry for newbie questions :-)
