1  Economy / Computer hardware / [SOLD] Two B52 and Two B29 miners on: June 03, 2018, 02:29:22 PM
Two B52 miners as is, still sealed in boxes, without PSUs, $1500USD each in BTC equivalent at time of purchase.

Two B29 miners as is, still sealed in boxes, without PSUs, $3000USD each in BTC equivalent at time of purchase.

Items are in Australia so delivery charge will need to be added to cost.

They have not been run or even opened as most people will be aware I am a bitcoin maximalist and I received these as a communication mix up during development for Halong's bitcoin miners.

3  Other / Meta / Welcome frodocooper as new moderator to mining on: December 05, 2017, 08:09:39 PM
With the rise in price of bitcoin the number of newbies coming to the forums and mining section at large has gotten out of control and the demand on me as the only active moderator was becoming excessive. Welcome aboard frodocooper by my recommendation as a new moderator to help keep the mining section under control.  Smiley

As a meta post about mining and not strictly about mining this post will be moved after a week or so.
4  Bitcoin / Mining / BITCOIN MINING INTRO & RULES OF THIS SUBFORUM - READ BEFORE POSTING on: November 17, 2017, 02:56:16 AM
1. Obey the overall rules of this forum:

2. This section is for BITCOIN MINING and related discussion ONLY. All bitcoin forks and alternate cryptocurrencies and discussion of them should be directed to a dedicated forum for those, or one of the altcoin subforums on this forum. All discussion regarding them will be moved without warning to the altcoin sections. If your topic is related to multiple currencies, then unless it is primarily about bitcoin it will be moved. Even if it is about sha256d mining but not about bitcoin it will be moved. BITCOIN mining is done today ONLY with ASICs, and any discussion of mining with CPU, GPU or FPGAs will be moved to the altcoin mining section.

3. Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs - . You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware. You will not find software in this section to help you mine bitcoin in this absurdly inefficient manner in this subforum. It would cost you thousands of dollars in electricity per year to earn only a few cents in bitcoin. Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today. Any discussion outside of ASIC related mining, except in the interests of academia, will be moved to the altcoin mining section. There isn't any point attempting to mine bitcoin with CPU or GPU even in the interests of learning as it shares almost nothing with how bitcoin is mined with ASICs and will not teach you anything.

TL/DR Summary:
 - You CANNOT meaningfully mine bitcoin with your PC or laptop no matter how powerful it is.
 - You CANNOT meaningfully mine bitcoin with your tablet or phone no matter how powerful it is.
 - Mining apps for your phone or tablet that claim to mine bitcoin are almost certainly scams.
 - You CANNOT find software here to mine bitcoin with your PC by itself.
 - You MIGHT be able to do one of the above with altcoins, but such discussion goes into the altcoin mining section.
 - You CANNOT find or post software here to mine on other peoples' PC without their permission.

4. Use the subforums as much as possible:

Mining support - This is for all questions regarding understanding the process of BITCOIN mining, and any issues with setting up hardware, configuration issues, stability issues, etc. Where hardware has a dedicated support thread by the manufacturer or maintainer of the hardware, there will be a post in the hardware subforum so please use that first. CPU, GPU and FPGA mining support will be moved to the altcoin mining section.

Pools - This is for all questions and discussion regarding BITCOIN pools, their operation, support etc. Where a pool has a dedicated thread from the owner, admin, or support staff of the pool, please use that. If the pool has a self moderated thread, then you are allowed to create your own personal thread to discuss those pools to not be prone to censorship by the pool owner/admin. Altcoin pools will be moved the altcoin pool mining section.

Mining software - This is for all posting of new BITCOIN mining and mining related software, pool software, proxies, controllers, monitors, web page design, apps etc. Discussion of software for education purposes to understand mining related functionality can go here. All altcoin mining related software will be moved to the altcoin mining section. No trojans, botnet, web page miners etc. are acceptable here - threads will be removed without warning and posters banned.

Hardware - This is for dedicated discussion regarding BITCOIN mining hardware ONLY and hardware in development. There should be only one topic per new piece of hardware, preferably started by the creator of the hardware, and they can then provide support for that hardware on that one thread. Where hardware has no manufacturer representative on this forum, the thread can be started by anyone but all discussion should remain in the one thread. If the manufacturer has stared a thread but it is self moderated, then you are free to create your own personal thread to discuss that hardware and avoid the manufacturer's censorship, but discussion of actual support should go in the Mining support subsection.

  Hardware - Group Buys- This is for coordination of BITCOIN mining hardware group buys ONLY. Threads can be created by the initiator of the group buy or expressions of interest, or discussion of existing group buys if a moderated thread exists elsewhere. It is NOT for selling hardware. All altcoin mining related group buys well be moved to the altcoin section.

 Mining speculation- This is where all BITCOIN mining related opinion discussion goes. Opinion means mining related speculating about new hardware, difficulty, economic effects, profit estimates, requesting opinions, asking for hardware recommendations etc. All altcoin mining related speculation will be moved to the altcoin mining section.

 Anything else that does not belong into one of those categories above, such as mining related offtopic discussion can go into the top mining section, but it must be BITCOIN mining related. Non mining offtopic discussion will be moved and non bitcoin mining discussion will be moved to the altcoin mining section.

5. Mining altcoins, even if you get paid in bitcoin, does NOT amount to mining bitcoin. Ethereum is NOT bitcoin. Monero is NOT bitcoin. Litecoin is NOT bitcoin. Bitcoin cash is NOT bitcoin and so on. Any discussion regarding mining anything NOT BITCOIN will be moved to the altcoin mining section.

All virtual mining - such as cloud mining, purchasing hashrate etc. is a service and NOT bitcoin mining. Discussion regarding cloud mining, contracts, hosting services, renting hashrate etc. belong in the economic services subforum and not the mining subsection.

7. Scam accusations belong in the economic scam accusation subforum, even if it is bitcoin mining related.

8. Mining hardware for sale or wanting to buy goes into the "economy - computer hardware" subforum. Mining hardware that is for mining altcoins belongs in the altcoin mining marketplace forum.

Threads that have been redirected to another subforum will be done silently if there is only an opening post. Any threads that have been redirected after some responses exist for that post will get a redirection thread message where they were originally posted to make it easier to find for followers of that thread

8  Bitcoin / Mining speculation / Japanese company GMO announcing new hardware and mining operation on: September 13, 2017, 11:53:57 AM
Some of you may have read the announcement about a Japanese company getting into mining. At this stage they're just announcing their plans and have started posting what they expect from their hardware. The details are in Japanese which fortunately I can read.

Beginning with mining hardware. The chip will be developed and manufactured domestically. Each module will be 10TH/s. 48 volts DC. Each system board has 8 modules. Each blade has 2 boards. Each rack takes 8 blades coming to 1.25PH. The Data centre will be 16x35m floor space housing 500PH/S.

Of more interest is their hardware description:

計算性能 10TH/s
消費電力 500W以下

設備   ラック、冷房、配電、消防、セキュリティ

電力   再生可能エネルギー(地熱、水力)

Estimated capability: 10TH/S
Electricity consumption: <500W

Mining chip manufacturing: Stepwise increase to 50,000 chips.

Facilities: Racks, cooling, electricity distribution, fire extinguishers, security.

Electric power: Renewable energy (geothermal, hydroelectric.)

Probably the most interesting aspect is 10TH/s for 500W which would make it class leading efficiency. The website also says they'll be using 7nm technology...

Of course we've heard of great claims of efficiency in hardware from newcomers in the past who have failed to deliver on their promises so at this stage it needs to be taken with a grain of salt.

Future plans (timeframe to be determined)

(1) クラウドマイニング事業
1. Cloud mining operation

Explains cloud mining much like any other operation that they'll be selling.

(2) 次世代マイニングボードの販売
2. Next  generation mining board sales

Public sales of their hardware!

(3) GMOコイン株式会社への仮想通貨供給
3. Provision of virtual currency to the GMO Coin public company

This appears to be them starting a cryptocurrency exchange under a daughter company to their main one.

TL;DR This established Japanese company is getting into bitcoin mining hardware and is aiming to make class beating efficiency mining hardware that it will eventually be selling to the public, timeframe unknown...

The bitcoin mining world desperately needs something to break the bitmain stranglehold on the global hashrate. Hopefully this is the beginning of something that other companies will do too. This is no new company formed just the mine bitcoin, but then bitmain has been working with mining for a long time now and understands it a lot better than the newcomers. It will be interesting to see if that existing knowhow counts for more than what established companies have to back them.
