"If the green lines had engaged in intelligent conversation with FG over the past 6 or 7 years and knew his academic background, then they may have realised that there is an alternative to brute force and it will blow your mind."
From what I've read QBT's algorithms aren't an alternative to brute force, the algorithm's are advertised as narrowing the nonce range to increase the probability of finding a target hash. Personally I have doubts QBT will be able to do what they're saying, especially using SaaS. Because of the network hash rate even millisecond latencies will make a difference, basically because of the number of nonces crunched in that time. The current network hash rate is over 500 Exahash per second, or more than 0.5 Exahash per millisecond; So in the case of SaaS, for every ms delay between a miner talking to a QBT server and receiving a response the BTC network will process over 500,000,000,000,000,000 nonces. The QBT server will therefore have to be very close to the miner and have the processing power to make superfast calculations in short order.
I have no idea how QBT's software works, in respect of the transaction data within individual blocks, and whether QBT's software produces its nonce range based solely on the header portion of the block, or processes the range against the entire block including the transaction portion of the block. If QBT's software just processes the header, and produces its target range from that alone, it would suggest that QBT will send out the same range of nonces to every miner subscribing to the service, irrespective of the transaction data inserted into each individual miners block.
Just because I'm sceptical doesn't mean QBT haven't found something special, It's just that I haven't seen any evidence to suggest they've achieved their 2.6 times improvement at the current network hash rates and difficulty levels. Until I've seen real world independent reviews with results backing up the improvement claims, I'll remain sceptical.
