Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

got 4 samples today.... show some pics or it didn't happen spiccioli samples have full of small design bugs, already make a TODO list. unfortunately, the firmware side is a bit delayed. i could only do the test by previous icarus bitsteam. hours for no error now. i hope they can make a breakthrough in the near future. this afternoon, i tested the on-board power module at school's lab . it can provide a 16A continues current for each FPGA core, 25A peak. form 7~14A is a wide high-efficiency Zone (>85%). looks like Lancelot can become a very good development platform for various of third party bitsteams. tomorrow i will take some photos. it's black night now:D |

My bitcoins can't wait to go to your wallet |
Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

Wow that is awesome. Is it just for your testing purposes, or will they be for sale?

do you want one? Not me personally, but I imagine that some of the guys with large clusters might make use of them. What's the maximum power draw for each port, and the total maximum? |
