El Salvador plans to attract miners using geothermal energy El Salvador's president Nayib Bukele has instructed the state-owned geothermal energy company LaGeo to draw up a plan offering bitcoin mining facilities with very cheap, 100% clean, zero-emission renewable energy from our volcanoes. https://twitter.com/nayibbukele/status/1402680890057166858



build up power plant needs much time and investment. it's not useful. just for PR.
the attached pic is very limited watt: around 3-5MW.

All these carbon emissions in relation to bitcoin mining have nothing to do with reality and can only be applied to countries where there is a shortage of electricity, otherwise just speculation, because according to research, the annual electricity costs of bitcoin miners are 113.89 TWh, while in the production of gold, the figure reaches 240.61 TWh, and in the banking sector-about 263.72 TWh https://www.scribd.com/document/508170253/Galaxy-Digital-Mining-On-Bitcoin-Energy-Consumption#from_embed


all these chart has no sense.
the fact is bitcoin mining used a lot energy. and in winter, use a lot coal-burn energy.

A couple good links regarding power usage:
Mining power usage
Power usage comparisons
On that comparisons page they looks at the power used in the US alone to power always-on but idle devices: result is that power used for idle devices would power the entire BTC network for 1.9 years.

Regarding China also taking several large aluminum refining plants offline, that is a double 'win' if their goal is to reduce carbon emissions. The reason is because not only does it require vast amounts of energy but also because the process of reducing Al2O3 into Al combines the liberated O2 with carbon from the electrodes used and that produces CO2. How much? 11.5 tons of CO2 per ton of Aluminum. That number is including the CO2 from using coal to produce power. When Hydro is used that same article states that emission drops to two to four tons of CO2 per-ton of Aluminum.
got the point.

try to build up local mining farm, most miner will be moved out of china.
let's help to decentralize the hashrate.

Sorry, since they still support anti-consensus things, I don't trust them for being fair also in their news. Do you have other source for this "information"?
I mean that 50% drop sounds catastrophic, but on the other hand the number seems to be plainly out of the belly. So without better proof, it can go straight into the FUD bin.
take a look the reply of next post.

This probably belongs more in mining speculation but we saw a 20%+ difficulty jump on the 13th, but that came after the 12% drop on the 1st, now if everything stays stable we are looking at about an 8% drop in a couple of days.
That looks more to me like the difficulty is moving with the price (with the 2 week delay of difficulty adjustment)

AT $60k+ BTC I was thinking about putting some S9 units back online.
At $40K- BTC I am thinking about pulling the S19 offline and selling it here.

How many other people wind up in the same loop?

Saying China is shutting down farms for carbon emissions is FUD at best.

so, go to google the policy of Mr. Xi announcement on May 1st. here is link: https://www.bloomberg.com/news/articles/2021-05-01/xi-vows-focus-on-emission-cuts-end-energy-inefficient-projects.

Why China shut down mining farm? Carbon Emission.
here is one great article, Predicted this shutting down action.

Bitcoin Segwit2M (B2X)-Green and Scaled bitcoin.
https://bitcoinnewyork.medium.com/bitcoin-segwit2m-b2x-green-and-scaled-bitcoin-3f0b0b32ac64

China are shutting down all high energy consumption, high pollution factory, because of Carbo emission. this is global govs unified action.
we will see the hashrate drop 30-50% at the end of this year. because in winter, all Chinese farm are shut down : no enough hydro , and gov control the carbon emission, shut down the coal-burn electricity supply.

good timing for over sea miners join mining. if you have cheap than 4 usd cent electricity, and enough capacity.

For me it's not really over until it's finally over, it's been a long time since I've been hearing about the dead of GPU mining most especially on Ethereum network but it never happened, same way people believe that Bitcoin will die lol, if ETH is out of PoW then we have other coins as well

Well as much as gpu companies pretend they do not like miners.  

They do.

So they have an interest in coin development.

To me Amd has a real interest if they combine an amd cpu and an amd gpu as the only way to mine AMDCPUGPU coin algo.

I would think it would work well.

AMD-DUAL-MINER-ALGO seems like something looking to be invented.





when PC took a huge chunk of gaming hardware sales from consoles, they want a cut from the profit from games.

now there is a market with ASIC and FPGA companies as competitors. they obviously want a cut from crypto mining profits.

but the tricky part is algo that can be ASIC'd and FPGA'd and algo change/alter. games on the other hand are games since the beginning until the end. gpu companies are watching but are not trying to be overexposed for the mean time

even if an algo is good for a certain gpu/cpu company. it is the coin that decides if there is money to be made, ETH is a defi/ponzi fest/scam fest/casino/hack fest/ etc.. a coin that is mining for the sake of "validating transactions" is soooo "ASIC"

that's why exchangers casino like binance and ftx are soooo into platform defi/ponzi fest/scam fest/casino/hack fest/ ...talking about BNB and solana---go gamble some more, and ponzi some more hehehe.


I have an idea for the future... a multi ponziverse blockchain oligarchy.

these technocratic overlords like AMD and NVIDIA make their own coin that will be mined efficiently by their proprietary hardware...or ASIC companies will get there first? exchangers already started it, maybe the hardware manufacturers should go into defi/ponzi fest/scam fest/casino/hack fest/ mode.

11  Local / 中文 (Chinese) / Re: 区块链入行十一年有感 on: May 01, 2021, 09:50:22 PM
12年时候显卡矿工入的圈,因为自己就是软件工程的这些年陆陆续续做了钱包,区块链浏览器,现在是某条国内还算有知名度公链的技术负责人。好多年没用的远古帐号忘记密码无法找回了,所以新开了一个上来聊聊,因为这个论坛也许是唯一一个早年入圈人可能会潜水的地方了。

国内的大部分区块链项目(ICO/Defi)的项目方都是为了赚钱,代码复制一下就上线然后配合资本的运作,高度控盘制造暴涨制造fomo效应。从根本角度来看大部分国内的区块链项目和资金盘没有本质的区别,唯一的差别就是会慢慢的枯萎,现阶段的火热Defi项目可以看看17年那波ICO的公链。另外一小部分项目其实是公司拿传统投资困难,通过ICO/Defi圈一波资金用来养公司,然后项目就表现出全力以赴但是无能为力的状态。也许的确是有努力想做成一点事情的项目,但是我现在有稍微深入接触的这些国内的大项目都不是出于这个目的。

当然除了区块链的底层项目之外我们中国人的一些区块链周边产业做的还是不错的,也碰到过一些用心在做产品的这类公司。比如对接区块258692出块人的公司的时候可以明显发现职业素养很不错; 和QQagent沟通过程中也可以明显感觉到为人满靠谱;XXtoken钱包的老板的老板谈业务合作时候也是直接了当很舒服。这里也安利一下选择产品的时候可以多选这几家的,毕竟上梁正了下梁才不会弯。这个理论来自于碰到过很多国内项目的创始人就是忽悠人圈钱,然后开发也大概率忽悠老板混工资,项目一上线就各种安全问题。至少我看一个产品靠谱就两点一个是老板为人如何,一个是对接的工程师素养如何,还是满准的。

关于区块链技术未来发展方向来看,首先所谓的政府使用联盟链这条路遥遥无期。区块链是组织行为模式的改变不是简单的丢数据上链存证这一点就让推动政府使用变得极为艰难,中间牵扯的利益太大了。公链这一块至少国内最近几年没有什么有突破的,所谓的跨链技术只不过是来几个人保管资金然后另外一条链给你代笔的包装罢了。这一点倒是满佩服以太,波卡这类的突破方向的。他们在做分布式系统层上很难的一件事情,我觉得失败概率偏大但是如果最后成功了是真的可以给区块链行业带来突破的意义。比特币其实不需要太多的改变做好资金的流转就够了,至于性能这一块注定是重要的交易链上,不重要的交易放到二层中心化的系统中执行。

在区块链行业中时间长的人不说所谓的财富自由但正常的花费应该都是够了,不是特别理解为什么还热衷中圈钱而不是出来做一些推送行业发展的事情。 所以说新入圈的人,少想着一夜暴富,守好钱包里的btc吧。

My thoughts are eth will fuck it up much as they did back in 2017-2018.


Agreed. There will be unforeseen issues trying to do something they planned to do 2-3 years from now, in 6 months.

In the meantime, people need to stop paying 3-4x MSRP for gpu's, and ignore Metroid's crystal ball as well. It's batting .001% these past 5 months  Tongue

Ethercoin.org -- Peer to Peer Smart Electronic Cash

Ethercoin (ETE) is a new generation of smart contract platform initiated by a group of professional and technical geeks worldwide to provide the overall scalability of layer-2 scaling in Defi world.

POW only

There must be a cost for currency issuance.we choose the energy as the cost of ETE.Pow is better than POS: dynamic and cost.all the hash power must be natively from internet: cpu, gpu, or store ability. now we choose to use ProgPOW. ProgPoW is a proof-of-work algorithm designed to close the efficency gap available to specialized ASICs. It utilizes almost all parts of commodity hardware (GPUs), and comes pretuned for the most common hardware utilized in the Ethereum network.

Deflationary Monetary Policy

Ethercoin setes up strict Deflationary Monetary Policy. ETE has a coin output mechanism similar to that of Bitcoin, i.e. the daily output will be reduced by 50% every two years.

happy mining for ever, join and enjoy.

EIP1559 will active in July; miner will loss huge revenue. at the same time, two company lunched new asic miner: bitmain, and Pineapple. both are around 3.6Ghs, 2500W. shipment from Jun.

under this double attacks, what should gpu miner do?

maybe one good choice, no eip1559, no asic miner, allways pow , no shifting pos.

Gpu miner, keep happy mining.

gpu mining --> dead, i mean really dead for 95% of miners around the world.
after eip1559 active, shifted to pos, yes.
how do you think about HD mining? like ipfs.

I would not be surprised if one day I see you complain that your funds are stolen because you downloaded some file from some website. How convenient it must be for hackers that someone would actually use their work and hand their private keys.

Exactly, people are too careless and don't have in mind security. Wallets and cryptocurrency in general are so vulnerable and we have to be very careful what we install, what data we share and especialy we shouldn't give out our private keys. If you don't act like that don't be surprised if one day you lose your coins.

Exactly, the algo's are all the same; BTC uses SHA256 (NSA) to hash the public-key into an address, and ETH uses Keccak-512 (Sputnik);

All private keys to address mapping is the same, private_key*generator->public_key, Hash(public_key)->address, compress address -> final address

You can do this yourself, don't need a downloaded malware. Just use 'KU' ( python pycoin util ) and generate the public-key from a private-key. Then apply the sha or keccak hash, and them in the case of bitcoin address format compress to base-58 ( cmd line tools on linux are already there for all these steps )

Why would anybody do this? It's not the same address,

Like somebody said here, the only reason for this is to get you to enter your private-key, so their malware can send it home.


If you must do it, I have explained above how do to it,

U can't really map btc to eth, as keccak & sha are different one-way trap door functions, called 'hashing'; if you go back to the priv-key, then you can map to public-key, as essentially ETH is just a clone of BTC, and they both use the same algo to generate elliptic curve arithmetic.

Bitcoin gets hacked 100x more than ethereum historically, because "BTC was where the money is/was", in time as ETH becomes more popular, and bigger CAP, you will see the criminals move to ETH. I think essentially that is what this malware is about, its an attempt to catch morons making the move from btc to eth, and thinking they can use the same priv-key, you can but why would you want to weaken security? ETH has good wallets, and good key generation built-in, why would you want to 'import' a private-key from btc of questionable security?


thanks a lot for your detailed explain.
as we know, the Public key is leak in early transaction .so, there is possibility to extract the PK of Satoshi,  and uses Keccak-512 (Sputnik) to hash the public-key into an ETH address. am i correct? if yes, kogitoken.org team hashed right ETH address, from Satoshi Public key. if it's right, it will be genesis air drop to Satoshi. it's ETH community big news.
thanks.

Multicurrency wallets all use the same seed words to create wallets/addresses in all kinds of cryptocurrencies, so it's not really surprising.

I wouldn't use it to send ETH to someone who gave me a BTC address though, I'd rather ask that person for an ETH address, and help them get one if needed.
the key how to get Satoshi's eth address. he won't public it. we can only convert it from the public bitcoin genesis block info. kogitoken.org team did it. now ,needs verify it.
20  Bitcoin / Bitcoin Discussion / Re: convert bitcoin address to ethereum address on: April 26, 2021, 09:42:45 PM
kogitoken.org generated an ETHEREUM address for Satoshi Nakamoto, used bitcoin genesis block data. seems this link https://free-online-app.com/bitcoin-2-ethereum-address-converter/ cannot.
