SFARDS Technology has successfully developed and produced the first FD-SOI 28nm SHA-256 (Bitcoin) and Scrypt (Litecoin) dual-mode mining chip SF3301, as we have previously reported. After more than one month evaluating, prototyping, and extreme-condition pressure testing, the first 28nm dual-mode miner, SFARDS SF100 is about to start mass production.

SF100 dual-mode miner has 24 SF3301 chips that support the following modes:
1. Dual mining mode, Bitcoin hashing power 1700 GHS + Litecoin hashing power 47 MHS, the power consumption at wall of whole miner is 960W.
2. Bitcoin single mining mode: Hashing power 1700 GHS, power consumption 770W.
3. Litecoin single mining mode: Hashing power 47 MHS, power consumption 180W.

With 0.45W/GHS + 3.8W/MHS, the power efficiency of SF100 is showing really good potential. It is also possible to overclock to certain extent (Sha-256: 2 THS, Scrypt: 55 MHS). Based on recent Bitcoin and Litecoin price, a dual-mode SF100’s revenue is similat to that of a to a 2.8-3.2 THS pure Bitcoin miner, which makes it equivalent to 0.3-0.34W/GHS power efficiency when it is dual mining. Taking June 19th price for instance, one SF100 generates 4.2 USD from Bitcoin and 3.8 USD from Litecoin, or a total 8 USD per day (without the costs for electricity deducted).

SFARDS Technology will start selling the SF100 dual-miner to public in July, though there is still no official end-user price announced and the first batch quantity is limited. The SF3301 dual-miner ASIC chips will be available for sale on August to people interested in using them in their own miner designs, again no pricing has been announced yet.

Is Somebody Stress Testing the Bitcoin Network

At the moment it seems as if somebody is deliberately stress testing the Bitoin network by sending more and more transactions, so the queue of unconfirmed transactions is currently at over 6000 and continue to increase. With so many unconfirmed transactions waiting to be included in a block this brings the debate around the current limit of 1 MB block size and if this limit should be increased. It could be like somebody is intentionally testing how will the network handle the extra load in its current state causing the presence of so many unconfirmed transactions waiting in the queue. Or maybe, though not very likely, the Bitcoin network is currently overwhelmed with too many real users moving Bitcoins around causing a big queue and having people wait more for their transactions to be confirmed.

– To check the number of currently waiting unconfirmed transactions on the BlockChain…

In a recent tweet about a high possibility of Greece’s bankruptcy leading to a market crash Kim Dotcom advices people to invest in Gold and Bitcoin in order to stay safe. It is up to you to listen or not to that advice, but we think that it may not be wise to ignore it completely. Kim Dotcom has been promoting the use of crypto currencies such as Bitcoin for some time now and it is highly possible that he also has plans for integrating crypto currency support in high projects such as the MEGA file upload service and. With that said he is also a controversial figure, but the situation in Greece is not looking good and they may as well be headed for bankruptcy and if it happens it will influence not only the European markets. With such an advice you might want to check out the service BitGold where you can not only buy Gold with fiat or Bitcoin, but also use it as a means for digital payments or redeem it as physical Gold if you wish to.
