1  Alternate cryptocurrencies / Altcoin Discussion / Stagnant Coins on: March 05, 2018, 06:25:36 PM
I wonder if there are many stagnant coins that are very similar to BTC. 

Stagnant might mean fewer than 25 blocks mined in the past 3 months.

Some points of similarity would be:
  • Block Time of 10 min.
  • Initial Block Reward of 50 coins
  • Total Issuance of 21,000,000
  • SHA256
2  Economy / Digital goods / [RFQ] Software Modification on Satoshi Client 0.8.1 on: March 23, 2017, 12:43:24 AM
I want a new procedure or so added to a private copy of the satoshi client 0.8.1. 

When finished, there should exist a new RPC call not unlike
    getcoinbasepayouts <hash> [n=1]
where n is the number of blocks to accumulate totals over.  This shall work even if the block-hash is a chain-tip that is stale.  The default for n is 1.

The output from this RPC call shall give the list of all bitcoin addresses and their corresponding amounts that were paid in coinbase transactions by block-hash and the previous n-1 blocks.  It should not be stylistically jarring compared to the other RCP responses.

Please feel free to produce a quote on producing the diff files which produce working source when applied to
    git clone
This alt-coin client is virtually identical to the 0.8.1 bitcoin client.  You may or may not be able to develop your code from the core 0.8.1 bitcoin client on the bitcoin block-chain if you already have that on hand.

I am still undecided whether this alt-coin was an April fool's prank or not, I am aware that the last block was mined on or near last September 2016, and that there may not be any active nodes, other than my intermittent one.

The terms will be fixed bid, pay on acceptance.  I do not think there is a large amount of work for someone already up to speed.  This request is valid for delivery by April 1, 2017, but may be re-issued.

3  Economy / Auctions / [Auction][WTS] Novel Android bitcoin application on: September 15, 2015, 11:07:10 PM
Previously, I have sold shares in an ASIC miner at auction, and have been judged as trustworthy and transparent, a remarkable achievement.  Some of you may remember that my photograph of this miner appeared in the Wall Street Journal along with my real name.  The long, boring, and real time unfolding of this saga is in the thread and the associated blockchain transactions, transparently visible to anyone.

For the past year I have considered a new use of Bitcoins and an Android application that implements it.  I have not seen anyone else mention this idea.  It is, at the same time, a new idea but also a completely straightforward use of Bitcoin as currency.  I have consulted with friends, enthusiasts, Seniors, Elders, and one or two others, and I have thought carefully through their reactions and comments.

I have a probably irrational exuberance that I can get rich and also increase the value of Bitcoin if I completely conceptualize, specify, implement, and market this idea.  I am tempted to work on this without a day job.  You probably now have a sense of where this is going.  I don't think this is suitable for a KickStarter project, as it probably counts as a software project that is too early in the process.

I don't want to simply blather the idea to the world and not have any funding and possibly have someone else implement it.  However, I do have to tell some people if I want to go the funded route.  What I have decided to do is this:  I am willing to email the very short version of my idea without any obligation, and without a non disclosure agreement (NDA), to any qualified person.  To be qualified, you have to have some Bitcoins.

So here is the process.  

If you want to read the 1 page concept summary:
  • make a refundable deposit to this bitcoin address:  1B2iffMMCBwMU7SnY8QzyScJYGLi7va1VA
  • While there is no formal minimum deposit, it is pointless and annoying to sprinkle dust on the blockchain.
  • I will deduct the reasonable transaction fee of 0.0001 BTC when making the refunds.
  • You will want to be sure you send the funds from an address that you can use to sign a message, and that I can send the refund to.  For example, use or your own Satoshi reference client.  Do not use a mixer or send from an exchange.  I will refund to the sending address.
  • I will notice who is qualified and send the funds back sometime after block 375,699, or about a week from today.
  • If you are not sure that you know how to send funds from a certain address, send some funds to yourself and look at the transaction at  

Additional thoughts

Of course, I will pay close attention to
  • who makes the largest total deposits.
  • how much the total of deposits are.
  • I will only send the document to the top 3/4 of respondents.  You can bump your bid from the same sender address.  (yeah, there ain't no sender in Bitcoin.  Deal with it.)

So, fire up your wallet and send a larger amount than anyone else.
4  Bitcoin / Development & Technical Discussion / What is the probability of a 40 min 6 block streak? on: August 24, 2015, 07:45:23 PM
When the difficulty and network hash rate are in sync, what is the probability that 6 blocks will be found in 40 minutes?

5  Bitcoin / Bitcoin Discussion / Group bid on US Marshals Service bitcoin auction on: June 22, 2014, 09:10:29 PM
I have asked the US Marshals Service for clarification on whether I can form a group of people and bid on the group's behalf.
I have asked a bank whether they will give me an account number to be used only for this purchase, and which I can publish.  The USD would only flow between this account and the US Marshals Service.

This is the 11th hour for me to be able to participate in this.  If you are potentially interested in bidding, please see the form linked off of my signature below without undue delay.

Also, look at the process that I plan to use.

7  Economy / Computer hardware / [WTB] [WTS] [AUCTION] April Avalon Flea Market on: December 30, 2013, 06:30:49 PM
Edited 2014-03-29
This auction ends in mid April, at block 296352.  Bids included in or before block 296352 are valid.
The revived auction details start at post #24

Edited 2014-01-19
This auction is active for January.
Auction ends 2014-01-31. The ending block will be confirmed near that time.  A rough estimate today is block 283156.

If you want your Avalon in this auction, post in this thread.

I am willing to act as escrow, blockchain-auctioneer, and general organizer of an end-of-year Avalon flea market.

If you want to buy or sell before the end of 2013, this is the place to be.

Your funds will be at an address that I control.  The seller will know that you have committed, I will release the funds when the seller has proof of delivery.  I will make a final decision in the case of disputes.

This is a central location.  You can get high visibility in the busiest Avalon marketplace.  The funds are paid and I act as your escrow agent.  The network effect means that all Twitter or Facebook exposure helps each of you.

I take 1% for my commission, regardless of where I send the funds.

I, and the Avalon community, need to know what an in-hand Avalon is worth.  For some people, this has important tax implications.  Also, it's just time for a flea market & all around shake-up.

This is a multi-winner blockchain auction.  I have held previous auctions of this nature.  The rules will be similar to previous auctions, both single-winner and multi-winner.  This auction will add the capability of multiple sellers with different minimum bids.

That is a pesky detail, isn't it.  Winning buyer pays shipping as an extra expense.  I can't think of any other fair rule.

The auction is live now as a 1 seller, 1 winner auction.  The auction will end at about block 278075 278000.  This block number is subject to change as announced in this thread, to keep the ending time near 11 PM GMT 2013-12-31.

If you want to sell your Avalon in this auction, please post your interest here.  It will take me a couple of hours to write rules that can handle multiple-winners, multiple-sellers, each with their own minimum bid.  The official rules will be dense formal writing, and they will use this document as a starting point.

8  Economy / Computer hardware / [WTS] Avalon Batch #2 (auction) on: December 26, 2013, 10:14:07 PM
I am selling 1 used Batch #2 Avalon at auction.

  • The auction will run through about Dec 30, so it will be a purchase made in 2013.
  • This is a blockchain auction.  To bid, you submit payments to 1JE7PkQSHEy66n3dHAqxJC62aBKzUmWMhz
  • To be considered, your bid must be included in or before block 277700.
  • Only send from an address that you control and can sign messages from.
  • To increase your bid, pay more money with the same from & to addresses.
  • If your payment comes from several addresses, your total bid will be pro-rated to each address. 
  • I will refund all non-winning bids in full.
  • The refunds will go to the address that they were received from.  Do not use mixers, or pay from exchanges.
  • There is no minimum bid.
  • I reserve the right to cancel the auction for any or no reason at all.
  • You can't tell whether I bid or not.  Assume your own the worst case scenario and bid accordingly.
  • The wallet is very helpful in setting up payments for this auction.  Bitcoin-qt requires a bit of advanced knowledge to work correctly, as it likes to use a lot of addresses.
  • Proof & performance of the miner can be monitored online
  • I have held a similar auction in the past.
  • I have never shipped outside the US.  Please think carefully before bidding from afar.  The item is in Minnesota.
  • In case of tie bids, the bid with the latest (largest block number, or largest transaction number) of the last payment loses.
9  Bitcoin / Project Development / [BOUNTY] Ubuntu 12.04 Environment to compile bitcoin on: December 22, 2013, 09:24:37 PM
I want an environment to compile bytecoin (BTE) under Ubuntu 12.04 (Precise Pangolin).  This is the 1:1 bitcoin clone that was released April 1, and may or may not be an April Fools's gag.

I will have a newly installed and updated standard Ubuntu 12.04 (Precise Pangolin) virtual machine (Oracle VirtualBox), and I will test your script in that environment.  Certain posts suggest that related altcoins, especially CNC, will give a clean make in Ubuntu 11.04.

You will provide a shell script that runs as root, that makes a complete environment to compile bytecoin, and does a clean make of bytecoin. 
I will own and publish the script.  You may do anything else that you wish with it.  I have made an initial effort to do this, and there are some missing dependencies.  Some of the altcoin threads discuss these dependencies.  I would rather pay you to handle these details than duplicate your expertise. 

If you have trouble connecting to a node, you may try addnode add in your configuration file.

for example:

#sudo apt-get install ssh, ntp, git, <anything else that is necessary>
#other installs as may be necessary

#git the source

#perform the make

Please submit a bid denominated in BTC and a deadline.

I will consider making payment in USD or BTE, provided that we agree on the exchange rate.  If I pay in BTC or BTE, I will disclose the TXiD.

10  Economy / Trading Discussion / Blockchain Auction Software "needs" discussion on: October 15, 2013, 07:00:30 PM
This is a continuation from an Avalon auction thread.

This thread will start out discussing software to support blockchain auctions.  The view is to develop an idea of the community's needs that the software will solve.

Probably anything related to auctions is on topic. (<--- words I already regret)

11  Bitcoin / Hardware / Avalon 55nm ASIC open source design contest on: October 07, 2013, 09:30:25 PM
Avalon has announced a design contest.

The timeline is very compressed.  I thought this would be a good place to gather any thoughts that potential customers have for design elements, and any comments that other designers / contestants have to make.

The break-even time matters as well.  More cool features cost design delay and component cost.  A URL for a pre-populated calculator might help the designers decide whether to push an adequate design out now, or spend more time cutting costs.

The only design element that is fixed is the 55 nm Avalon ASIC chip.  Everything else is designer's discretion.

This is a self-moderated thread.  Please stay civil and on topic.

The chip is specified as 1 GH/s @ 2.05 W with 128 Hash units on the chip.

I have not noticed any pricing information.  You might want to submit a URL for a profit calculator that will suggest the time to break even that you consider realistic.

13  Bitcoin / Hardware / Avalon Batch #2 Break-even on: August 29, 2013, 03:47:04 PM
This thread is for people to report when their Avalon (reached / will reach) Break-even.
Electricity cost makes it more complicated.  I would just use the Avalon cost and list electricity separately.
This is a self-moderated thread.  You have probably read my thoughts on hate postings elsewhere.  Say what you want, but keep the language civil and based on reality.

BTC paid; payment txid; Date received; Date of break-even neglecting electricity; other costs (customs, shelving, cables, security, storage); free form comments.

14  Economy / Computer hardware / [WTB] Avalon Batch #3 PDU on: August 20, 2013, 07:46:04 PM
I assume people will need to buy or sell Avalon parts from time to time.

Is the power distribution board different for a Batch #3 Avalon?

Are board files available?

Will anyone sell one?

15  Bitcoin / Hardware / Value Estimate of Avalon Miner today on: August 17, 2013, 08:00:25 PM
I want to know the value of an Avalon miner.

I used this calculator with presets for a 3 module miner.
An additional step should be to discount each future week to the present value using some interest rate.  I have not done that step.

This gives me a value of about 70 BTC for an Avalon.

I am sure that many people would use different numbers for this.  For the power, I used 650 W * 80 GH / 65 GH --> 800 W, as it is overclocked.

I'd like to hear what other's think.

16  Bitcoin / Group buys / [OPEN AUCTION] HashFast Baby Jet on: August 16, 2013, 11:02:05 PM
HashFast announced the 1st engineering run of their Baby Jet for Oct 20-30 delivery in order of payment.  The cost is $5,600, the power draw is 350 W, and the hashrate is 400 GH/s, next day shipping is approximately $200.  This is a limited production of 550 devices, and they are steadily selling.  At least 381 391 have been sold.

This pricepoint is similar to buying 5 Avalon 3 module systems at a cost of $1,120 each, with a credit for 2,900 W of electricity.

There is a lot of skepticism about pre-pay for systems at this time, and if you are a noobie who dreams of getting rich, I want to strongly discourage you from getting involved in my purchase.  I absolutely do not want to minimize the risk, and if HashFast takes the money and produces nothing I can not make it good for you.  Many ventures are promising to bring high hash rates online, and this will strongly dilute the earnings of everyone.  I am certain that the earnings, priced in BTC, will fall steadily.  It may fall so fast that this unit never earns as many BTC as it costs.  That is, it fails to achieve break-even.  

At least two fixed price group buys are open. waldohoover DyslexicZombei Moogle

I'm willing to collect money, administer the unit, and make the payouts.  I did this with a Batch #2 Avalon, and the hash rate as well as the payouts are visible to the public.

I offer 512 shares in a bitchain auction for 100% of the net output of 1 Baby Jet.  You may check my previous auction and see that I did return losing bids.

  • If sufficient funds are paid, I will order the unit(s).  
  • If the shop sells out or I otherwise do not place an order, I will return the funds promptly.  
  • I may contribute my own funds to the auction.  
  • I reserve the right to cancel the auction and return funds at any time, for any reason.
  • I may purchase more than 1 Baby Jet from auction proceeds, and ownership will be prorated for the entire Baby Jet farm, and not restricted to a specific unit.  
  • The auction will end when no additional units are available for sale, or at any earlier time.  
  • I may purchase a Baby Jet with auction proceeds while the auction is still open and the winner list is not final.
  • I may find windfall means to acquire more Baby Jet units after the auction ends, and add them to the Baby Jet farm with pro-rated earnings and shares.

I will stand ready to receive the machine, plug it in, and follow the instructions that are provided.  This is not a special skill, and you are not relying on any level of expertise on my part.  I anticipate that many owners will attempt to overclock or modify their devices, and that firmware updates may be issued;  these are not special skills within this community, and I may or may not do so.  I will report publicly and factually the actions that I do take.  In order to be qualified to bid, you must have these same skills to own and operate a Baby Jet yourself.

I have plugged some numbers into a mining profit calculator.  In particular, I moved the estimated delivery date to 2013/12/20.  I made similar calculations back on February 18 when I bought my Avalon, and I am making significantly less than those calculations indicated.  You should make plans that these calculations are wildly optimistic.  I do not guarantee these numbers.  I don't have any expertise in making any prediction on the future difficulty, or the future value of bitcoin.  This calculator suggests that the Baby Jet will have an end of life the week of 2014/12/26.  For purposes of this group-buy & auction, I declare that the Baby Jet has no value beginning 2014/12/26 and full ownership of it will be abandoned to me at that time.  I may chose to declare this venture closed on or after 2014/12/26 with no additional discussion or obligations.  I may re-furbish or otherwise change the Baby Jet, or leave it unchanged, and mine with it as my own private machine after ownership has been abandoned to me.

Nonetheless, this calculator suggests that a Baby Jet could earn 92 bitcoins.  A naive calculation gives each of the 512 shares a value of about 0.1796 BTC.

The 1st 2.0 BTC mined by each Baby Jet will be paid to me for establishing this auction.  I will deduct 0.10 BTC each week for electricity, internet, & housing.  If other costs arise, I will document them and deduct them.  One such cost would be any registration of bitcoin miners that is required by US, Minnesota, Texas, or other regulators.  My administrative time is free for routine operations.  When a Baby Jet is ordered, the corresponding auction proceeds become mine to do with as I choose.

The mechanics of the auction:

  • You pay from an address where you can receive bitcoins and sign messages.  If you don't know how to sign messages, please don't bid, as it will make both of us unhappy.  You may want to buy 1 share, or many shares.  I have provided several addresses as a shorthand to make bids on a block of shares.
  • It is good practice to pay from an address that you newly create and fund for this auction.
  • I will calculate the price / share that each bid-address pays each submit-bid address.  This is calculated on the total balance, not on a per transaction basis.
  • I will order these as equivalent 1 share bids from largest to smallest.
  • I will count up to some integer multiple of 512 shares.  Those bids will be winning bids.
  • There is no minimum pay-in.
  • When a portion of a block-bid has been outbid, I will continue to hold the funds until the auction is over.  This will allow the possibility of buying more than 1 Baby Jet.

I do this manually.  It is tedious.  And slow.  This is an opportunity for a block-chain savvy programmer.

  • The submit-bid addresses are

17  Bitcoin / Group buys / [GROUP BUY AUCTION] HashFast Baby Jet (CANCELED) on: August 15, 2013, 08:52:34 PM
This auction is canceled.  I will delete this topic in a day or two.

The HashFast Baby Jet is offered for sale in limited quantity, delivered in order of payment.

they ask for $5,600 payable in bitcoin.  Prepaid.  Delivery estimated for October 20-30.  Estimated hash-rate 400 GH/s.  Estimated energy efficiency 1.0 J/GH.

Previously, I sold income shares in a Batch #2 Avalon.  This Avalon is hashing, and the mining income and disbursements are visible on the blockchain.  Delivery on this Avalon was anticipated in late March and actual delivery occurred in mid July.  The actual hash rate for the Avalon is 80/65 of the advertised rate, and the earnings are less than 1/4 of the rate at the time when many people paid.

I have not placed a Baby Jet order.  This auction is an attempt to raise about 60 BTC in order to do so.  I will only sell about 1/2 of the future income for that amount.  Many people in the community have experienced regret in placing pre-paid orders.

Due to delays and ecosystem changes, purchasers of other bitcoin offerings are worried that they cannot break even on their purchases.  There is significant risk that this group buy will not work out well.  I cannot do anything to "make good" on unfortunate events.  Some Avalon owners have had smoke and sadness.  This is one example of unfortunate events.

I will receive the machine, plug it in, and follow the instructions that are provided.  This is not a special skill, and you are not relying on any level of expertise on my part.  I anticipate that many owners will attempt to overclock or modify their devices, and that firmware updates may be issued.  These are not special skills within this community, and I may or may not do so.  I will report publicly and factually the actions that I do take.

I am offering about 0.5 of the income from the BabyJet for the total price of $5,600 in shares targeted at about $25/each.  This sets the share at 0.002 (0.2%) of the net mining income.   You will have very small exposure, but you will pay approximately twice the manufacturer's price.  I will deduct an electricity fee equivalent to 350 W at at the current BTC-e exchange rate before dividing the funds. My current rates are below $0.09 / kWh but they are not guaranteed.

If sufficient funds are paid, I will order the unit.  If the shop sells out, I will return the funds promptly.  I may contribute my own funds.  I reserve the right to cancel the auction and return funds at any time, for any reason.

The mining lifetime of this unit is administratively declared as 20 weeks, and begins when the unit begins hashing.  I chose this number based on my own thoughts and cannot justify it.  During the mining lifetime, I will pro-rate the cost of 1 share and offer buy back offers from time to time.  This will give people the option to recover cash due to unforeseen circumstances.  After 20 weeks, I may quit mining at any time that I chose, and the equipment becomes fully owned by me and no liquidation & payout will occur.

The bitcoin world is difficult for both buyers and sellers.  Please be careful.  I strive to be fair and sensitive, but also to impartially follow the rules, and the thread for the previous auction may provide interesting reading for you.  I have returned bids that were clearly blunders, and I have refused to return bids that I thought were simply buyer's remorse.

  • The submit-bid address to is 14eBzhQBYBCiDy7SV8s6iR9oUKHnBadnYH
  • The admin address is 17AMeSmnZwW1MGykLEmAngQcxqnyEfrLET.  Transactions to or from this account are not bids and are not refunds.  Do not pay to this address.
  • The mining-proceeds address 1BiEPg9oANN8ow3wzRKftsdRsotVPk6bav will receive the mining proceeds, and initiate the payouts.

The auction will run according to the rules that I posted last May.  My previous auction is included by reference.  I have not declared a partial winning schedule, and I may or may not do so.  I call particular attention to the fact that I may reduce or increase the number of winning bids.  

Discussion is welcome.  Links to discussions of HashFast, my previous auctions, or other matters that may help people make informed decisions are all on topic.  Factual discussions of success or disappointment may be particularly valuable.  Threats of lawsuits or violence against any vendor for any reason are off topic.  Disclosure of personal information is off topic unless it is your own (but seriously, why?)
