BitCoin.com Mining Pool User Naming Format

Saturday, August 19th, 2017

Pool Worker format:  User.Worker   where user is your user name in the mining pool and worker is a name you put on the mining device after the period.  It's a way to see each machine individually for monitoring purposes.

  • If your UserName on the website that you registered with is USER that is the first part.
  • WORKER is the part after the period.  Now you could say WORKER-2 but if you do it appears to only use WORKER and truncates the -2.   I guess that means do not use a dash character.

Claiming your BitCoin Cash SpinOff from BitCoin

Wednesday, August 2nd, 2017

Anyone who held bitcoin at August 1, 2017 @ 12:20 p.m. UTC should have an equivalent amount of BCH attributed to their Bitcoin private keys.

….so now the question is do I need a wallet specifically for BitCoin Cash?  Probably.  Will update when I claim.

RansomWare Attack in Europe based on Petya

Tuesday, June 27th, 2017

Was notified by a friend in the USA that their company is under ransom ware attack and the miscreants are asking 300 USD equivalent in BitCoins to free each device.  They mentioned Petya.  With all this being so wide spread I did a cursory check to see what is going on.   It is notable to me that I keep hearing about hospitals being affected.  Perhaps some of those cheap Indian I.T. workers that hospitals are using are moonlighting?

In windows 7 there are no hooks in Control Panel to turn smb1 on and off.  They suggest editing the following registry key.  To enable or disable SMBv1 on the SMB server, configure the following registry key: When I attempted this there was no entry for SMB1.  I created it and set it equal to zero.  Not sure if that will help me.

Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters                 

Registry entry: SMB1 
REG_DWORD: 0 = Disabled 
REG_DWORD: 1 = Enabled 
Default: 1 = Enabled

 

 

Epiphany on BitCoin, China and the Next Reserve Currency

Friday, June 16th, 2017

I read the following article on ZeroHedge:

    Is The People's Bank Of China Manipulating The Bitcoin Price?

In this article it mentions that more than 50% of the hashing power of the BitCoin network is located in China.  Because of that if China wanted to control the BitCoin blockchain they could by putting pressure on the BitCoin miners.  

Synthesizing this information with the following bullet points:

  • China is where the most powerful mining devices are designed and constructed and thus China could hold back supplying hashing equipment a generation or two and legislate cryptocurrency dominance for he who hashes fastest controls the block chain.  
  • China is a manufacturing power house.  This manufacturing capability is the sort of thing that backs a currency.
  • The next reserve currency will be a cryptocurrency

What will the outcome of this current set of conditions be?  Given the above conditions it is hard to see how the next reserve currency is anything but a Chinese based cryptocurrency unless another method to prevent at will changes to the blockchain database.  With BitCoin it will become an industrial foot race. One the USA is no longer able to win and China has the social energy to dominate.  Ethereum is reported to have an implementation that inhibits this computational arms race.  If this is true then necessarily the heat will shift off of BitCoin and onto Ethereum.

With regards to BitCoin China can through manipulation

  • break the network to make it unworkable
  • ruin by taking away the desirable features and thereby causing users to flee the network
  • manipulate the price for their own benefit

I suspect they will ruin it.  That means BitCoin is probably not the final version of what we all know has to be our libertarian decentralized private central banker killing cryptocurrency.  That's my opinion today at least.
