LargeCoin
On March 6th, 2012, LargeCoin announced their intent to develop a Bitcoin mining ASIC, using a structured ASIC approach.[1]
Delivery was projected to be in July of 2012[2].
Although no formal cancellation was announced, no significant new information on this project has been made available after March 12th, 2012[3]. On July 25th, 2012, LargeCoin posted in a thread titled "LargeCoin is scared of BFL" noting "Yes, we certainly are [...] our assertion is that [BFL] have discovered new manufacturing processes that are vastly more efficient than anything the semiconductor industry has seen before".[4]
