2  Bitcoin / Bitcoin Discussion / A proposal: Forget about mBTC and switch directly to uBTC (instead of satoshis) on: November 21, 2013, 06:41:51 AM
This solution continues to allow us to have symmetry, and allows scalability beyond subdividing a satoshi, and is backwards compatible with the use of uBTC and mBTC.

You may wish to give uBTC some special name (if not microbits or microcoins) so that this idea works just like the "skip to satoshis" idea.

One problem with the "skip to satoshis" idea is that satoshis are difficult to convert to bitcoins, and microbits are easy to convert to bitcoins. Abandoning bitcoins entirely is now being proposed by some people in favor of satoshis only, which will just confuse things further.

Notice that with SI prefixes for large numbers we have:

Code:
1  uBTC = 0.000 001 BTC
1K uBTC = 0.001 BTC
1M uBTC = 1 BTC
1G uBTC = 1 000 BTC
1T uBTC = 1 000 000 BTC

Suppose we call these uB for short.

All of the arguments for skipping to satoshis still applies, except that we now have:

1M uB = 1 BTC

instead of

100M satoshi = 1 BTC


We also have: 1K uB = 1 mBTC, and similar simple conversion between other SI prefixes, so those can still be used without breaking anything or adding unnecessary confusion.

Also note that we can still talk about satoshis (in the distant future) easily in terms of uB:

0.01 uB = 1 satoshi

So we have a natural "cent" like many currencies do, which is near the limit for how most people are able to reason about numbers after a decimal place.

And when we subdivide a satoshi then we can move from microcoins to nanocoins much more naturally, without having to explain why there is some arbitrary number of 100 million satoshis.


The current price is about $0.61 for 1000 uB.

9  Economy / Speculation / Perhaps some good can come of a BS&T default. on: August 23, 2012, 04:33:02 AM
I see about 16 orders visible on mtgoxlive at the moment, all for about 4000 BTC each, distributed very evenly.




Assume for a moment that pirate defaults (whatever you may think about the situation).

It has occurred to me, that if the community writes a simple trading bot for pirate (or really, he could write it himself since it would be a very simple bot), maybe pirate could at least use his BTC to help stabilize the price.

He probably wants to sell a bunch of his BTC it anyway, and he could choose to sell off during sudden price spikes only, and keep the market depth reasonable.

At least then some good would come of BS&T.

11  Bitcoin / Bitcoin Discussion / Gauging interest: A mining contract marketplace. on: August 05, 2012, 04:48:13 AM
https://ferroh.com/mining/intro


Most of this service's features are complete, but if you vote against using this, then it can be put on the backburner while other projects are completed instead. Your vote matters.

If you don't think it's a good idea, please just vote "I won't use this". We'll build something else.

Note that there are some differences from what you might expect from a mining contract:

  • A 1GH/s mining contract produces bitcoins as if it were a 1GH/s mining rig that has no downtime, no stales and no variance. The number of bitcoins that a contract produces depends on network difficulty only, and no other factors.
  • Contract seller funds must be held in escrow while they hold the contract.
  • Ferroh will pay interest on contract seller funds that are held.
  • Contracts can generate a maximum payment to the buyer of 1.5x the purchase price (necessary to be able to guarantee that sellers can fulfil their obligations in every scenario).
  • Contract durations vary, there are only ever two durations available.
  • A 3 month or longer contract duration is always available.
  • All contracts are bought and sold in BTC, however automatic BTC->USD conversion is available to contract buyers, prices set based on aggregate bitcoin exchange prices.
  • You can cancel contracts that you've sold by buying contracts of equivalent hash rate.
  • You can cancel contracts that you've bought by selling contracts of equivalent hash rate.
  • Buyers do not have to trust the sellers or vice versa, Ferroh arbitrates everything and guarantees that contract obligations will be met.

Please voice any questions or concerns Smiley

The "Introducing Mining Contracts" link I posted 6 months ago seems to have been mysteriously deleted from reddit.com/r/Bitcoin. That is frustrating and I wonder if Theymos can weigh in on that.

You may recognize the previous Ferroh Mining Contract service.

You may also recognize Ferroh's D3 gold buy/sell service (no longer in operation due to friction with Blizzard-Activision).

We're discussing moving this service to a separate domain, so that it is separate from the other Ferroh stuff.

19  Bitcoin / Mining support / Stop BAMT from creating noMine file when it sees no GPUs? on: May 03, 2012, 07:16:20 AM
I have a BAMT machine that only manages FPGA & ASIC units.

Since it has no GPU, it creates a noMine file and refuses to mine. To start mining, I have to manually delete the file and /etc/init.d/mine restart which is troublesome.

Is there an easy way to get BAMT to start cgminer anyway and not create the noMine file when it doesn't see a GPU at boot?
20  Bitcoin / Mining support / BAMT with cgminer: BFL units not visible in gpumon (cgsnoop not running?) on: May 03, 2012, 05:52:47 AM
gpumon is not seeing BitForce units connected to a machine running BAMT, and I would like to fix this.
Update: Another machine on the network can see the status of the singles in mgpumon though.


In bamt.conf I use:


settings:

  cgminer: 1
  cgminer_opts: --api-listen --api-port 4028 -O blah -o http://blah -O blah -o http://blah -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 -S /dev/ttyUSB4 [...etc]
  cgminer_port: 4028
  do_cgsnoop: 1
  do_bcast_status: 0


In cgsnoop.conf I have:


broadcast: 1
broadcastport: 54545
127.0.0.1:4028,bamt17,unspecified location


I see no cgminer API errors, how can I determine the reason that gpumon is not seeing the BitForce units in cgminer?

ps aux | grep cgsnoop shows no results. So I assume cgsnoop is not running. I guess it is running though, since I see the status of these machines is being broadcast on the network to mgpumon.

When I manually run /opt/bamt/cgsnoop it runs for a second and then closes. What could cause that? I guess that is irrelevant.


UPDATE:

I can see the BFL units in mgpumon on another machine on the network, so cgsnoop must be broadcasting their status. But I still cannot see these units in gpumon on the machine that is controlling them!
