1  Alternate cryptocurrencies / Altcoin Discussion / MicroCash - New CryptoCurrency on: April 19, 2012, 02:59:07 PM
I've copied this from the SolidCoin forum.

So, we have a new name for the project. MicroCash. The site is going to be put up at, which will resemble the current site with changes. MicroCash represents pretty much what we are doing, microcomputers creating cash, and also that we allow easy micropayments in cash.

Some important notes
*) MicroCash is going to include every SolidCoin in it,
*) When MicroCash launches there is going to be a "Launch Bonus" , meaning mining rewards are going to be MUCH higher than normal for a week or so. Total inflation from the bonus will be 100K
*) MicroCash will not have trust nodes
*) MicroCash will have a similar hashing and pool mechanism as SolidCoin
*) MicroCash will not have trust accounts. Meaning the only coins brought forward will be the 2.8 million user coins
*) MicroCash will have an alternate 51% mining protection mechanism which will mean the power of the network is more in the users hands
*) MicroCash will have a different address format. It looks like micro(QSM3PKS3EOZBUZO4A)cash

Here are some potential new logos

And here are a list of most of the changes over SolidCoin v2 :-

*) A new way to send/recv funds securely over the MicroCash network, meaning you can download the client and be sending/receiving cash within seconds. No blockchain download required
*) Can now get paid merely for running a node
*) MicroCash Accounts now gain a form of "interest" which is collected from all network fees and redistibuted to accounts based on their total MicroCash holdings. Increase your MicroCash amount and get more interest
*) Chain donation address added. Send money to this address and it redistributes it evenly to every MicroCash account
*) Every account on the network has a daily fee of 0.005 MC or a half cent. Meaning 1 MC provides enough account fees for 200 days.
*) Dual signature accounts allowed. Meaning you can now have two devices with 2 keys able to confirm a transaction. ie You create a transaction on your PC and your mobile phone confirms it. If your PC is ever hacked your funds can't be removed without your phone confirming it.
*) Transaction fees reduced to a fixed 0.005MC (half cent) for a normal transaction and 0.01 MC for dual signature
*) Transaction size is now much smaller, which means we can fit more in a block and have less disk/memory usage
*) Much improved custom database to store all blocks and transactions. Resulting in about 25% of the disk usage compared to v2.
*) Extremely fast transaction/block/account lookup, resulting in less CPU usage running a node.
*) Improved Proof of Work hash and handling. Now reference previous blocks with a SHA256 to improve disk loading
*) Increased mining income to match $1-$2 range instead of $3-4 range
*) Powerblocks are removed
*) Trust nodes and trust blocks are removed
*) The 10 trust accounts are removed
*) Improved P2P handling
*) Much shorter address format and new hashing mechanism for them. Accounts store public keys so that once set it's more secure than ripemd160
*) Denial of Service code added, can now ban nodes that flood the network
*) Ability to donate MicroCash to nodes for passing on transactions and blocks
*) URL and email callbacks for accounts on a node. Allow developers to get transactions pushed to them instead of constantly polling
*) Trading on exchanges will be possible within the client
*) Ability to add labels or information to transactions you send to others
*) Can create payment codes that clients accept with amount, address and information tags already filled out.

2  Economy / Economics / Bonds and other economic ideas on: March 21, 2012, 09:52:04 PM
Recently on the SolidCoin forums there was a thread about upcoming ideas for a future version. One of these was the concept of bonds, whereby you forfeit your SolidCoins for X months and get a return of Y at the end of it :-

Are there any economists here that would like to see something similar incorporated into Bitcoin? Or any ideas in general about economic improvements they would like to see in cryptocoins?
3  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin USD price hits new high on: February 17, 2012, 01:06:23 AM

The recent economic changes in SolidCoin which made mining a lot more fair has also seen the SolidCoin USD price increase dramatically. Since the change was announced we hit a high of $0.14 per SolidCoin and it is now trading in decent volume around $0.06 . A few weeks ago this was around $0.02 .

If you want to read more about the economic changes in SolidCoin and how we managed to fix the inflation/deflation issue without a central bank being needed please read :-
4  Alternate cryptocurrencies / Altcoin Discussion / artforz and coblee gpu mining litecoin since the start? on: February 10, 2012, 02:39:39 PM
Recently one of our developers mtrlt spent about 4 hours adding scrypt support to Reaper, the SolidCoin GPU miner.

It currently gets ~720KH/s on a 6990 . Is it possible the "botnet" or "darkpool" mining Litecoin is actually artforz and coblee who have been mining LiteCoin using an unfair advantage since the start? Conning litecoin users into thinking it's a CPU mining chain when in fact the GPU dominates it?

Artforz publicly admitted to creating a GPU miner for litecoin numerous times, however he also said his GPU miner of scrypt (the algorithm used in Litecoin and which he selected) only got 9KH/s on a 6870 GPU. This is suspicious when our developer can get massive improvements over CPU with only 4 hours of effort, on the order of 150 times faster than artforz. Either artforz is terrible at creating GPU miners or he lied to litecoin users.

Coblee, the "creator" of Litecoin, copy- pasted Artforz's code from Tenebrix and was communicating with him around the time of previous coin fairbrix and his latest attempt Litecoin. He went around giving the exact speech artforz did, so they both were involved in spreading the "GPU Hostile" mistruth . The fact that that it is found that the coin is far from GPU Hostile should lead to questions being asked of both coblee and artforz as to how and why they misled the public.
5  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin Mafia Bitcoin Merged Mining Pool - Pays out in SolidCoins on: January 30, 2012, 09:54:33 AM

SolidCoin Mafia

What is SolidCoin Mafia?
SolidCoin Mafia is a Bitcoin merged mining pool that pays out in SolidCoins. When a Bitcoin/NMC/I0C/IXC/DEVC block is won those coins are taken to various exchanges and used to buy SolidCoins using a variety of algorithms.

What is the aim of the pool?
To provide more liquidity for SolidCoin trading and always ensuring there is at least one large buyer available.

Why should I mine here? Can't I just mine SolidCoins if I want them?
Yes you could mine SolidCoins, though often buying them with Bitcoins allows you to get more SolidCoins. Also by mining at SolidCoin Mafia you are economically supporting SolidCoin and helping to provide some stability to the value.

How are payouts handled?
We calculate a pay per share that is roughly 50% of the current market price. So you get your SolidCoins upfront prior to any block being found, though roughly only 50% what you could if you had that in BTC. When the automatic trading takes place users are then proportionally paid out any bonuses. Sometimes no bonuses may occur due to SolidCoin price increasing a lot between the the sale of the Bitcoins and the giving of SolidCoins for each share.

You can withdraw as soon as you have submitted enough shares to get 5 SolidCoins

Big Thanks to Karmaon and Ahimoth for working a lot on this concept. They Run the pool so if you have any questions PM them on the SolidCoinTalk forum or on IRC, freenode #solidcoin
6  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin v2.041 Released! on: January 30, 2012, 08:17:32 AM

We've released v2.041 which fixes a crash bug in the Linux daemon, also updated the license.txt

7  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin v2.04 Released! on: January 29, 2012, 04:25:13 AM
You can just download it straight from the home page. Including the source code.

Head on over to our forum to read about it, as this includes some new economic changes basing coin production on actual cost to produce in electricity rather than "nothing", which should eventually lead to stable prices needed for a working online currency.

This will likely be the last release on the "bitcoin code" as we are moving to a nearly 100% new code base to spread SolidCoin to as many platforms as possible and rewarding nodes for handling transactions.

If you are a business or use the RPC, please be aware that the bitcoin compatibility layer is now gone, you will have to use the new sc_ replacements which mean you need to specify amounts in integers and the wallet you want it to occur in.

8  Alternate cryptocurrencies / Altcoin Discussion / Litecoin 51% attacked? on: December 02, 2011, 11:31:10 PM
There was some discussion recently about Litecoin having a "dark pool" with about 55% of the network mining power. Coblee is aware of it and seems to be hiding the fact this imminent 51% threat exists to Litecoin.

It is possible this dark pool already done multiple 51% attacks as they seem to be continually stopping their mining and "doing something else for an hour or so" before resuming. Hopefully someone is monitoring the reorgs which have been occurring and determining if anyone is actually losing Bitcoins on the exchanges.
9  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin 2 - GPU mining and the future on: October 21, 2011, 01:31:57 AM
Satoshi developed a hashing algorithm in Bitcoin which saw GPUs dominate it, forcing CPU users to the dustbin and making it a lot more difficult for everyone to mine Bitcoin. Out of this grew the GPU farms and the Bitcoin mining community.

Prior to SolidCoin v2.0 I released some info saying we were going to a CPU algorithm for SC2, knowing that the trolls would attempt to copy the idea. The end result, tenebrix, a CPU miner, now a dead chain. (I won't mention fairbrix/litecoin since they are both also dying and just copied tenebrix).

In actuality the hashing algorithm I developed for SolidCoin v2.0 was designed to equalize CPU and GPU, to make them comparable watt for watt. Now SolidCoin would let anyone with a GPU (even NVIDIA ones) or CPU able to mine rather fairly.

Like all the core SolidCoin people know, we are the current technical leader of cryptocurrencies, with the most innovations and the most secure p2p currency, if you want an early alpha for GPU mining please visit our forum.

10  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin 2 Release - Monday 10th October 23:35 UTC on: October 09, 2011, 05:24:32 PM
If you like giant countdown timers :-

Monday 10th October 23:35 UTC

Also of note, 3 wannabe hackers from this forum claimed they would take down the SolidCoin 2 public beta and none have. Welcome to the future of cryptocurrencies, a truly secure network.

You can download the beta and see what all the fuss is about at the SolidCoin forums :-

11  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin v2.0 Public Beta on: October 08, 2011, 10:23:10 AM

Note, this is running in testnet mode to test that the SolidCoin v1 coins are working correctly for people on the new chain and also to stress test the 51% network defense algorithm in SolidCoin v2.0. It also gives time for the exchanges and pools to ensure they are working correctly with the new network.

There will be a 24 hour notice before the network resumes proper activity.

Windows Binaries (32bit and 64bit)

Linux 64 Binaries (GUI and Daemon)

And here are some of the new features
1) CPU mining is now possible through an internal miner, which also lets you connect to pools or your own computers to form a "super hash node" . Can also set a "share" amount, so instead of solving the real target, you solve smaller targets like pools do.
2) Multi wallet support
3) The only chain not vulnerable to 51% attacks
4) Major reworkings of the RPC code. Including
* splitting up getwork into sc_getwork and sc_testwork
* adding pool like features to the client so that pools can form much easier
* performance improvements
5) Major restructuring of the old SolidCoin/BItcoin code. Multithreading deadlock issues fixed, hundreds of performance improvements added, cleaner code to work on
6) CPF . Coin protection/promotion fund. A 5% amount is added and put into a fund which will help protect the currency when it comes to price, network stability and promotion
7) Block format changes to help improve efficiency when it comes to mining and also for future chain downloading improvements
Cool Send dialog improvements. You can now see the fee in advance, and also how much balance you will have left after sending a certain amount.
9) Windows x64 builds available
10) Windows installer automatically selects 32bit or 64bit client, one download makes it easier
11) Many UI improvements
12) Move to 4 decimal points instead of 8 for better looking "numbers" and making it easier to use for average user
13) No more saving settings in wallet.dat . All settings now saved in solidcoin.conf
14) Can now mark blocks you find in the blockchain with your own unique identifier
15) Coin inflation is now somewhat tied to difficulty.

12  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin v2.0 Coin List on: September 22, 2011, 05:31:57 AM

I have made a list of all SC 1.x addresses that have a balance >1SC that will be receiving coins in v2.0 of SolidCoin. Could all holders of SC1.x coins please verify the addresses they have.

When the public beta testnet is active (sometime within the next week) you'll be able to check that the new balance is transferred before the network goes live. Your wallet is what is used to verify that you are the owner of the new coins, so you don't need to do anything to have SC2.0 coins besides keep your wallet.dat. It is advisable you backup your wallet if you haven't already, prior to running on the public beta testnet or the latest version when it is released.

If you need more info please pop into IRC for live help or head to the official forums :-

And for a complete list of all addresses regardless of current value (~176000 or so) :-

All SolidCoin address balances
13  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin v2.0 features new hashing algorithm, faster on CPUs on: September 17, 2011, 07:18:33 AM

So for those of you who don't pop into IRC too often you will have missed some of the latest news on SolidCoin v2.0

It will now be CPU mining based instead of GPU based. Why is this? Well the blockchain format has changed to be more efficient for pools and networking, and due to this new miners were needed. Since new miners were needed anyhow I thought I may as well change the way block headers are hashed so that CPUs are more efficient (currently and for the near future) processing hashes as this gives SolidCoin numerous benefits.

1) You can still mine other coins like Bitcoin whilst simultaneously mining SolidCoins on your CPU
2) The amount of coins generated will be the same as the network adjusts difficulty based on number of hashes
3) No more need to run a separate miner, you can connect to your own client and pools from SolidCoin v2.0 itself, much easier to get your friends mining which will bring balance to the network
14  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin 1.10 Preview on: September 08, 2011, 07:13:29 AM

So as everyone should know work has been going on with the new 1.10 client. This new client has quite a few new features and hundreds of internal differences from the previous SolidCoin.

These include :-

*) Multiple wallet support. Including changes to API to support them for businesses. Still compatible with the old API through the selection of a "Default" wallet.
*) Networking improvements designed to improve efficiency of the connected nodes
*) Multithreaded rewrite. Hundreds of lines have been rewritten to provide a much smoother multithreaded experience.
*) Cleanup of the code. Restructured parts of it to allow it be extended more easily in the future
*) 64bit support on Windows
*) More GUI enhancements and features.

If you want to get access to a beta before the public release join IRC and wait for the announcement.

Comments and suggestions can be given at the SolidCoinTalk forum

17  Alternate cryptocurrencies / Altcoin Discussion / Step by step guide to mining SolidCoin on: August 29, 2011, 07:45:39 AM

I have started making a step by step guide to mining SolidCoin. I have had many PMs and emails about how to mine them so hopefully what I have put up there is a good start for anyone new to the mining business.

I'll be packaging GUIMiner with all the SolidCoin mining pools also for ease of use.
18  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin 1.02 Released on: August 26, 2011, 02:46:19 PM
SolidCoin is a peer-to-peer crypto currency based off Bitcoin, with the aim of providing a superior alternative when it comes to network stability, speed of transactions and security. Our aim is also to provide better tools to help businesses and users around the world embrace the SolidCoin currency with much less pain and security troubles compared to Bitcoin.

Download SolidCoin 1.02 Here

Currently only Windows binaries and Source Code are provided as we work through some build issues on Linux and MacOSX. Source will also be provided on github in a few hours. Keep an eye on the thread for updates.

-Fixed crash on exit bug
-Fixed some more user interface bugs dealing with sizes set by magic numbers instead of proper sizing
-Updated About box
-Changed some Mac compiler settings
-Updated irc rules to use more channels now that a few thousand users have joined the network
-Updated all docs and build instructions due to libpng support needing to be in wxwidgets on linux
-Changed build process. Now there is a builds folder which contains the makefiles. moved obj creation to a non src directory.
-Moved media out of src directory to keep it clean
-Changed default rpc port to 8555 so it doesn't conflict with some linux services
19  Alternate cryptocurrencies / Altcoin Discussion / SolidCoin 1.01 Released on: August 25, 2011, 02:14:19 AM
SolidCoin 1.01 has been released! Read bottom of post for what's new

Download Here

Binaries For Windows, Mac OSX, Linux (32bit and 64bit)
Source also available

^ this screenshot is of the bounty wallet. 25000 SolidCoins have been given away in bounties so far. A bit over 6000 SC has been donated.

What's new

v1.01 - August 25, 2011
-Added security checkpoints at block 10000 and 20000
-Fixed bug in "Create New Address" dialog which stopped it being the right size with certain font sizes
-Fixed bug in "Send Funds" dialog which didn't start at correct height in some situations
-Fixed crash bug when opening options
-Fixed startup bug which wouldn't locate already running SolidCoin.exe on Windows
-Improved main screen interface flow. Also added a logo button which takes you to SolidCoin website.
-SolidCoin RPC/JSON API extensions added which return SolidCoins as integer amounts (like banks operate in) as strings

instead of as "Real". Fixes some issues which can be experienced on PHP and other languages that exist in Bitcoin and other

-Still 100% backwards compatible with the old Bitcoin API, new functions added are just the beginning to help developers.

-These are the new methods which you can query that return both INTEGER and REAL (for human eyes) amounts


v1.00 - August 21, 2011 (initial release)

This is a graph showing SolidCoin difficulty, hash rate and exchange price. As can be seen, unlike the other chains SolidCoin's protocol is designed to encourage network reliability. A steady increase in price also shows the market is diversified enough that a mere few people cannot manipulate it.

Also of note is the current hoarding of SolidCoin's. Only 10% of the available SolidCoins are available to purchase.

20  Alternate cryptocurrencies / Altcoin Discussion / [ANNOUNCE] SolidCoin - new and improved block chain. Secure from pools on: August 21, 2011, 05:03:34 AM

Download Here

Public Mining started 5 minutes after this thread was created. Only 940 blocks or 30080 coins were premined for bounties.

SolidCoin is an open source digital currency, based on the cryptocurrency Bitcoin, which is distributed over a peer-to-peer network to offer irreversible, low-cost, anonymous and decentralized monetary transactions.

SolidCoin officially started on the 20th of August 2011.

How does SolidCoin differ from Bitcoin?
  • Faster transaction processing
  • Protection against pump-n-dump by large pools
  • Twice daily difficulty retargets
  • 3 minute blocks, 32 SolidCoins per block
  • Maximum coin generation of 18.9 million (18900000) to be reached by ~2022
  • Fixed transactions fees instead of unknown variable fees in BTC
  • Interface improvements
  • JSON API improvements
  • Different address format

But do we need an alternative to Bitcoin?
The answer is simply YES! Bitcoin itself has shown that P2P cryptocurrencies can work and can be relatively secure when it comes to only owners of the coins using them. However it is far from perfect.

As Bitcoin itself and other similar chains have seen, there are numerous vulnerabilities and issues in the protocol, including :-
  • Slow transaction speeds, often making waiting for confirmations unbearable
  • Near complete shutdown of network due to pump-n-dumps by large operators
  • Transaction fee nightmares, no way of knowing what a fee will be until you've tried to send funds
  • Concentration of Bitcoins into elitist early adopters that have no interest or desire to help Bitcoins be used by "normal" people
