Mining Litecoin

LiteCoin P2Pool
http://www.guugll.eu:18327

Username: <LiteCoin_address>

Password: <random_password>



Litecoin is the result of some of us who joined together on IRC in an effort to create a real alternative currency similar to Bitcoin.  We wanted to make a coin that is silver to Bitcoin’s gold.  We wanted the best innovations of Bitcoin and these other currencies to create a coin with all of their benefits, but nearly none of their problems.


Proof of Work


We really liked Tenebrix’s Scrypt proof of work.  Using Scrypt allows one to mine Litecoin while also mining Bitcoin.  We humbly offer a big thanks to ArtForz for the implementation.


Premines


Litecoin will come with 150 premined coins: just the genesis block and the first 2 blocks to confirm the genesis is valid.  We believe a coin needs to be released in a fair manner.  Having one person (or a group) control a large amount of coins that can be used as they see fit is against the decentralized vision of Bitcoin.  Yes, it is true that without a stash of premined coins, we will not be able to afford to pay for bounties, but we believe people will see the virtue of this coin, invest in it as early adopters, and will be willing to spend time creating services to make this coin better.


Fast transactions


We were impressed by the convenience of SolidCoin’s fast transactions.  Although we know that fast confirmations are not necessarily as secure as Bitcoin’s slower confirmations, they are very convenient for small merchants who don’t need transactions to be super secure. The average Litecoin block takes 2.5 minutes, one quarter of Bitcoin’s 10 minutes.  So if merchants wanted to be as safe as Bitcoin, they can wait for 4 times the number of Litecoin confirmations as compared to Bitcoin. But most merchants can readily accept 1-confirmed transactions for small amounts of litecoins.


Difficulty retarget


We will keep the retarget block the same as Bitcoin’s 2016, but because blocks are found 4 times faster, difficulty will retarget about every 3.5 days.  The combination of fast retarget times and Scrypt proof of work (Litecoin will not compete with Bitcoin for miners) means we expect to not see the sort of problem Namecoin encountered; hashing power that leaves more suddenly than it came, causing a high difficulty slog for everyone who stayed.


Coin generation


Miners will generate 50 coins per block.  In light of our faster blocks, to properly mimic Bitcoin’s generation trajectory, we needed to change the blocks at which coin generation is halved.  Bitcoin generation is halved every 210,000 blocks.  Litecoin generation will be halved every 840,000 blocks.  For those of you doing the math, Litecoin is scheduled to produce roughly 4 times as many coins as Bitcoin, about 82 million litecoins.


Fairness


We have come up with a plan that we believe is most fair.  Some previous coins were released without Windows binaries or without source code; we consider this as unfair as it is unsafe.


We released the source code and binaries ahead of time… 3 days before launch.  People had time to compile the source and run the client on their machines against the Litecoin testnet.  So people were able to make sure everything was working well before the launch.  We also had a poll so that people can vote for a launch time that best suits them.  At the time of the launch (Oct 12 03:00 GMT), we released the genesis hash and everyone started mining at the same time.  All it took was a simple change in the config file in order to mine the real coin instead of the testnet coin.


51% attack


The problem with alternative currencies is that the network hashrate is likely low when the coin starts up, making an easy target for any potential 51% attacker. With a little hope, a little prayer, a lot of hype, and due to our innovative release, there was a large hashrate from minute one.  We believe this deterred any attackers from targeting this chain.  As expected, there was a lot of natural orphaning of blocks, due to having so many people mining on the chain at once.  With block locking at every difficulty change, we were able to avoid any attacks from succeeding. (if there were any)


Source code


The source code is here:
https://github.com/litecoin-project/litecoin


This is based on the latest Bitcoin code. You can either build the daemon version (litecoind) or you can build the gui version (Litecoin QT). See the build docs.


Similar to Bitcoin, you may want to create a litecoin.conf file here:

Windows: C:\Documents and Settings\<username>\Application Data\Litecoin

Win7: C:\Users\<username>\AppData\Roaming\Litecoin

Mac: ~/Library/Application Support/Litecoin

Unix: ~/.litecoin


Port is 9333. Open if on your router if you know how. This will allow you to have more than 8 connections.

And default RPC port is 9332. This is the port miners will use to communicate with your client/daemon.


Sample litecoin.conf file:


Code:

server=1

rpcuser=user

rpcpassword=password

#Change this if you want to use a different rpc port for mining

#rpcport=9332


#Only uncomment this if you are running litecoind and want to run Litecoin in the background (not Litecoin QT)

#daemon=1




So tell us what you think. Come to the Litecoin forums (http://forum.litecoin.net) or drop by #litecoin or #litecoin-dev on freenode IRC to chat.

Mining Feathercoin

FeatherCoin P2Pool
http://www.guugll.eu:11327

Username: <FeatherCoin_address>

Password: <random_password>



FeatherCoin is a fork of Litecoin using its latest build. I am a supporter of Litecoin and will be following Litecoin’s patches and releases. The Litecoin team is currently working on a newer release and this project will move with them.


One of Litecoin’s biggest advantages is the Scrypt-based hashing algorithm. This offers a different solution to Bitcoin, while still being able to run on GPUs. There are many Bitcoin forks using the original hashing algorithm, but with the advent of ASIC mining hardware, we are starting to see how much trouble they can cause. ASIC mining hardware is expensive, but outperforms GPU hardware and will eventually make GPU Bitcoin mining redundant.  Scrypt based crypto currency is safe guarded from the effects of ASIC mining.


Feathercoin has a block reward of 200 coins and will have a total of 336 million coins. This makes it four times that of LiteCoin, this is the same position that LiteCoin was set against BitCoin.


Default port is 9336 – Forwarding this port can help if you have connection problems

Default RPC port is 9337 — This is the port is point your miners towards if solo mining

2.5 minutes block target

504 blocks to retarget difficulty

41.4% maximum change on difficulty retarget

Block reward halves every 840,000 blocks

Mining Novacoin

NovaCoin P2Pool


http://www.guugll.eu:15327/static/

Username: <MinCoin_address>

Password: <random_password>




Novacoin is a virtual currency, just like LTC it uses scrypt hashing and thus it can be mined in the same way as Litecoin by CPU and GPU. It has been created by bitcointalk user Balthazar. Currently it is performing pretty well, selling for higher prices than LTC with lower difficulty on the network. This makes it worth it to mine NVC instead of LTC and transfer them into BTC to minimize the risk. New coins, especially when claimed to be a scam have a risk to drop in price suddenly or be can 51 attacked. At the current hashrate this is not a big risk though unless several big pools decide to do so together.


Is Novacoin a scam?


There have been claims that over 200.000 coins were premined by the developer. The developer has claimed that only 60.000 coins have been premined but apparently BTC-e admitted that they got 100.000 coins to accept this currency on their exchange. This does not directly mean the coin is a scam, some cryptocurrencies with premined coins have survived. It only means that (if the numbers are correct) thedeveloper can easily cash out 100k coins and make a lot of profit. In some cases trust in the coin is lost as was with solidcoin. However, other cryptocurrencies with premined coins have survived. If you want to stay onthe safe side while mining Novacoin you just have to make sure you don’t keep too many of these coins and exchange them in to something else like BTC.


NovaCoin was the first PPC fork, but not a clone! New versions ale coded standalone, not from new ver. of PPC.


major changes:


1. Scrypt chashing!

2. initial reward of 100 not 10000

3. slower reward drop

PPCoin cuts a half from reward for every 16x diff adjustment.

NovaCoin cuts a half from reward for every 64x diff adjustment.

4. POW difficulty adjusted for scrypt

5. POS difficulty adjusted for 100 times less coins.

6. ROI for POS changed to 0.05 coin per 1 coinyear [dynamic from 4.1]

MinCoin (MNC) — a minimalist version of Bitcoin optimized for CPU mining using scrypt as a proof of work scheme.

*Only 10 million coins total will be generated

*1 minute block targets for ultra fast transactions

*To encourage early adoption block values for first 3 days are :- 500 MNC, 100 MNC, 50 MNC

*After first 3 days block value will be 2 MNC per block until all coins mined which will take roughly 10 years

*Retargets 2 times a day


Mining started at 12:20 GMT April 3 and was announced on IRC and the WWW not long after. There is no

premine!


Help getting started-


Solo mining:

Run mincoin.exe or compile the source from github. It should close down immediately after not finding a valid config file.


Go to %appdata%\mincoin directory and create a file called mincoin.conf . In this file add two lines


rpcuser=user

rpcpassword=pass


Then save the file. Or you can download the file from here and place it in the same directory:-
https://dl.dropbox.com/u/36733610/mincoin/mincoin.conf

Now run mincoin.exe again.


Run CGMINER or REAPER and point it to http://127.0.0.1:9335 with the username of “user” and password of “pass”


If you use CGMINER set the flag “–expiry 1″ option to make sure you avoid stales, ie

cgminer –scrypt -o http://127.0.0.1:9335 -u user -p pass –expiry 1

Mining BBQcoin

BBQ-Coin P2Pool
http://www.guugll.eu:13327

Username: <BBQ-Coin_address>

Password: <random_password>



BBQCoin often abbreviated to BBQ or BQC is a scrypt based blockchain fork of the original bitcoin source code, very similar to litecoin and launched only a short while after Litecoin.


Specs of the coin




  • Each block generates 42 coins



  • Difficulty adjustment 2016 blocks



  • block generated every 1 minute



  • Will never cease generating coins. “see coin generation schedule”



  • Block reward halves every 24 million blocks or around every 45 years.



  • Uses the Scrypt hashing algorithm



  • RPCPORT=59332



Estimated coin generation schedule




  • ~45 years total generated = ~1,008,000,000 BQC



  • ~91 years total generated = ~1,512,000,000 BQC



  • ~137 years total generated = ~1,764,000,000 BQC


This pattern continues indefinitely. The hard-coded limit of 4.2 billion will theoretically never be reached.



General discussion / history of the coin



It was launched by user Cubox and in his opening statement on the July 15, 2012, 10:27:01 AM


“This new *coin is not made for be traded, sell/buy. It’s just for “fun”. I have spent too much time to share it only with my friends, so i’m saying here his existance The main website will be on bbqco.in (not yet done) We will have an abe explorer too abe.bbqco.in is now opened, thanks to Someguy and D34TH, and if I have time, I will open a PPLNS pool (Merged mining ?)”


However this coin was not seen in positive eyes by some members of the forum (namely Luke-Jr(references needed) and Greedi), so Greedi performed a 51% attack on the chain and stopped people mining coins and rejected blocks from other users.


At the time of writing this I have been unable to see any other malicious work that was carried out during this 51% attack of the coin, but this attack soon meant that people lost interest and faith in BBQcoin.


Then on February 08, 2013, 07:58:05 PM it was announced by user markm that BBQcoin was still ticking along and has been since it started and that now that the attackers have left the alt-currency forum BBQ coin seemed to gain a little support and miners hopped back on in the hope of mining at not such ridiculous difficulties.


Since then user CaptChadd seems to have taken an active role in the BBQcoin community and has produced latest builds of the client for windows and has been promoting the coin, this is very useful as the original developer Cubox seems to have almost abandoned the project and the original source code is not available, though look in the downloads section as figroll, a member of the BBQcoin development team, has forked the original BBQ repository and made it available.



Exchanges



There are plans from more exchanges to support BBQcoin in the future…one of note is https://virexa.com/ but this exchange is currently still in testing phase at the moment.

Other Pools



But with difficulty ever increasing as more miners get on this chain, it is important for more pools to appear in order to secure the network further

Specifications

Algorithm: Scrypt


Block Time: 20 seconds  - Enough time to minimize orphans but still provide almost instant transactions.


Difficulty: Starts at 0.00024414 — It will take 6-8 difficulty adjustments (or ~13000 blocks) to reach desired difficulty of 1. It re-targets quickly to adjust to the environment, so stability should not be much of an issue. Miners should also find the system adjusts fast enough to be up to date, but not so fast as to make the environment unpredictable and unstable.  6 hours is target time. Every 1080 blocks(6 hours @ 20 seconds per block), the network scales the difficulty accordingly. Example: If target is 6 hours and it took 3 hours to find 1080 blocks, difficulty will increase 200%.


Reward: 20 coins per block, halved every 3 years — Consistent rewards encourage miners to support the network long term. Loyalty is rewarded. This also reduces volatility by setting the foundation on a stable path. Due to the fair launch policy, block rewards will grow in value until they reach the 20 coins per block reward. More details below. 4730400 blocks total.


Coin cap: 200 million.


Block confirmations: 5.


Fair Launch

Block

1080 —  Difficulty up until here is 0.00024414. Block reward of 2.


2160 —  Difficulty up until here is 0.00024414. Block reward of 1.


3240 —  Difficulty up until here is 0.00097656. Block reward of 2.


4320 —  Difficulty up until here is 0.00390624. Block reward of 5.


5400 —  Difficulty up until here is 0.01562496. Block reward of 8


6480 —  Difficulty up until here is 0.06249984. Block reward of 11.


7560 —  Difficulty up until here is 0.24999936. Block reward of 14


8640 —  Difficulty up until here is 0.98165069. Block reward of 17.


Difficulty will then rise to 1 and the block rewards to 20. The purpose of this is to give a period of time for miners to know about digitalcoin before others can mine too much of it and cause hoarding. The figures above can shift depending on the hash power of the network to smooth the difficulty rise to ~1 level.


Quick Start

Download the wallet and follow step 1 from the Solo Mining guide. Both found below.


That will get you connected to the network and synchronize your wallet.


Developers

Everyone is welcome to contribute to digitalcoin in any way. If you have expertise that you would like to contribute, please contact me. A stable network providing regularly near instantaneous transactions has potential for many exciting implementations.


Solo mining

1. Create a file called digitalcoin.conf  and put it in the root directory of your digitalcoin files(Example Windows 7/8: C -> Users -> Username->Appdata

->Roaming->digitalcoin). *In windows, choose save as All files in Notepad to save it with a .conf extension.


Sample digitalcoin.conf contents:


COPY BELOW THIS LINE

rpcuser=yourusername

rpcpassword=yourpassword

server=1

addnode=24.138.46.123

addnode=76.79.201.54

addnode=198.245.60.126

addnode=93.186.200.124

addnode=107.20.222.119

STOP COPYING ABOVE THIS LINE


(COMMENT: Forward port 7999 in your router firewall and/or software firewalls and send me your IP if you would like to be added to the nodes.)


2. Mine with the digitalcoin-qt wallet by launching it, navigating to Mining and putting in the username(rpcuser), and password(rpcpassword) you chose above. For port number, use 7998. The server will be the local IP of your machine, oftentimes localhost also works in the server field.


Alternatively, mine with cgminer using a .bat file or a modified shortcut command line.


To do so, use the following command line:


cgminer.exe –scrypt -I 11 -s 1 –expiry 1 –queue 0 -g 1 -o 127.0.0.1:7998 -u 1 -p 1


Please note 127.0.0.1:7998 is one possible local IP and yours can be different. 7998 is the local port the rpc miner listens on.


Forward port 7999 if you would like more incoming connections.


Pool mining

To connect to a pool, use the same command line above, but substitute the pool IP for the local IP.


Example: cgminer.exe –scrypt -I 11 -s 1 –expiry 1 –queue 0 -g 1 -o www.guugll.eu -u username -p worker.password


Pools will often post optimal settings so make sure to check those.

Troubleshooting

Wallet:

If you have any wallet download, block chain, or any other issue with the connections, try the following first:

In your digitalcoin folder in AppData, delete everything but digitalcoin.conf and wallet.dat(backup whole folder just for safety). Edit digitalcoin.conf and make addnode=24.138.46.123 as your only node, relaunch. After one launch, your client should build a peer list with only good nodes. Forward port 7999 if you have no/low incoming connections.


Compiling in linux:

If you have the following error, use this command: mkdir src/obj ; sh share/genbuild.sh src/obj/build.h ; cd src ; make -f makefile.unix


make -f makefile.unix digitalcoind

/bin/sh ../share/genbuild.sh obj/build.h

../share/genbuild.sh: 33: ../share/genbuild.sh: cannot create obj/build.h: Directory nonexistent

../share/genbuild.sh: 34: ../share/genbuild.sh: cannot create obj/build.h: Directory nonexistent

BBQCoin often abbreviated to BBQ or BQC

BBQCoin often abbreviated to BBQ or BQC is a scrypt based blockchain fork of the original bitcoin source code, very similar to litecoin and launched only a short while after Litecoin.



Specs of the coin

Each block generates 42 coins

Difficulty adjustment 2016 blocks

block generated every 1 minute

Will never cease generating coins. “see coin generation schedule”

Block reward halves every 24 million blocks or around every 45 years.

Uses the Scrypt hashing algorithm

RPCPORT=59332

Estimated coin generation schedule

~45 years total generated = ~1,008,000,000 BQC

~91 years total generated = ~1,512,000,000 BQC

~137 years total generated = ~1,764,000,000 BQC

This pattern continues indefinitely. The hard-coded limit of 4.2 billion will theoretically never be reached.


General discussion / history of the coin

It was launched by user Cubox and in his opening statement on the July 15, 2012, 10:27:01 AM


“This new *coin is not made for be traded, sell/buy. It’s just for “fun”. I have spent too much time to share it only with my friends, so i’m saying here his existance The main website will be on bbqco.in (not yet done) We will have an abe explorer too abe.bbqco.in is now opened, thanks to Someguy and D34TH, and if I have time, I will open a PPLNS pool (Merged mining ?)”


However this coin was not seen in positive eyes by some members of the forum (namely Luke-Jr(references needed) and Greedi), so Greedi performed a 51% attack on the chain and stopped people mining coins and rejected blocks from other users.


At the time of writing this I have been unable to see any other malicious work that was carried out during this 51% attack of the coin, but this attack soon meant that people lost interest and faith in BBQcoin.


Then on February 08, 2013, 07:58:05 PM it was announced by user markm that BBQcoin was still ticking along and has been since it started and that now that the attackers have left the alt-currency forum BBQ coin seemed to gain a little support and miners hopped back on in the hope of mining at not such ridiculous difficulties.


Since then user CaptChadd seems to have taken an active role in the BBQcoin community and has produced latest builds of the client for windows and has been promoting the coin, this is very useful as the original developer Cubox seems to have almost abandoned the project and the original source code is not available, though look in the downloads section as figroll, a member of the BBQcoin development team, has forked the original BBQ repository and made it available.

General MinCoin Info

MinCoin (MNC) – a minimalist version of Bitcoin optimized for CPU mining using scrypt as a proof of work scheme.


*Only 10 million coins total will be generated

*1 minute block targets for ultra fast transactions

*To encourage early adoption block values for first 3 days are :- 500 MNC, 100 MNC, 50 MNC

*After first 3 days block value will be 2 MNC per block until all coins mined which will take roughly 10 years

*Retargets 2 times a day


Mining started at 12:20 GMT April 3 and was announced on IRC and the WWW not long after. There is no

premine!


However, this does require a mandatory update to the mincoin qt client and daemon for all miners and pool operators.

We have made a thread to this effect here: http://mincointalk.com/index.php/topic,87.msg560.html#new

We request that everyone upgrade prior to block 75000 as that is the target block for the new Difficulty re-target of 60blocks

to take effect.

Help getting started


Solo mining:

Run mincoin.exe or compile the source from github. It should close down immediately after not finding a valid config file.


Go to %appdata%\mincoin directory and create a file called mincoin.conf . In this file add two lines


rpcuser=user

rpcpassword=pass


Then save the file. Or you can download the file from here and place it in the same directory:-


https://dl.dropbox.com/u/36733610/mincoin/mincoin.conf


Now run mincoin.exe again.


Run CGMINER or REAPER and point it to http://127.0.0.1:9335 with the username of “user” and password of “pass”


If you use CGMINER set the flag “–expiry 1″ option to make sure you avoid stales, ie

cgminer –scrypt -o http://127.0.0.1:9335 -u user -p pass –expiry 1

General MinCoin Info

Novacoin NVC Information

What’s the Difference between NovaCoin and PPCoin?


NovaCoin uses slightly different emission model.

NovaCoin uses scrypt hashing function for Proof-Of-Work.

NovaCoin implements BIP34, some other changes will be applied in the nearest future.

NovaCoin uses separated target limits for Proof-Of-Stake and Proof-Of-Work.

New blocks signing protocol allowed us to implement the full p2pool support.

What could you say about NovaCoin emission model?



It’s quite simple. There are two types of blocks, Proof-of-Work and Proof-of-Stake. Each makes contribution into existent coins volume.


Proof-of-Work block reward can be calculated using formula nBlockReward = 100 / (nMaxTarget / nCurrentTarget) ^ (1/6). It means, that reward cut a half every 64x multiply of difficulty.

Proof-of-Stake block reward based on CoinAge parameter and Proof-of-Stake difficulty. Interest can be calculated using formula nRewardCoinYear = 1 / (nMaxPoSTarget / nCurrentPoSTarget) ^ (1/6). It means, that interest starts from 100% per year and cut a half every 64x multiply of difficulty.

What’s Stake or Proof-of-Stake?


Stake/Proof-of-Stake is term referring to the use of currency itself (ownership) to achieve certain goals. In NovaCoin proof-of-stake is used to provide minting and transaction processing in place of proof-of-work. Please refer to our design paper for details of this approach and our implementation.


The ‘stake’ field in the getinfo output shows the currency amount you currently staked to protect the network. This amount is subject to the holding period of 520-block maturity window before you can use it again (it would return to your balance once matured).


How is it energy-efficient when there is still mining?


The energy efficiency we refer to is long-term energy efficiency, as in long term we do not require the use of energy to sustain the network.


Currently proof-of-work remains the most practical way of providing initial minting of a crypto-currency. So we decided to keep it as part of our hybrid design.


Why do you need central checkpointing?


As of PPCoin v0.2 centrally broadcasted checkpointing is no longer a critical part of the protocol. It’s main purpose now is to defend the network during the initial growth period and help ensure a smooth upgrade path if critical vulnerability is found. We are confident that central checkpointing can now be gradually weakened and eventually removed to achieve similar decentralization level of Bitcoin as the novacoin network matures.


Regular users could ignore broadcasted checkpointing by using -nosynccheckpoints option, if they wish.


When can I start generating proof-of-stake blocks?


After 30 days the network would start seeing proof-of-stake blocks. If you have balance novacoind would automatically try to generate stake for you. If you find a stake the reward is calculated using current proof-of-stake difficulty and coin-years amount consumed. The reward amount is added to your stake amount and is shown together in the ‘stake’ field of getinfo output.


Because stake is withheld from spending for 520 blocks, if you do need to keep your balance around to be spent soon we provided a configuration option ‘reservebalance’ to help you keep your balance from being used by stake. You can add a line ‘reservebalance=10000′ to novacoin.conf and restart your novacoind. This way novacoind would try to keep your balance above 10000 coins when generating stakes.


Can I use encrypted wallet?


Yes. Encrypted wallet is supported but there is some difference from Bitcoin. If you use an encrypted wallet you would have to unlock the wallet in order to mint blocks. For user security we added an option to the walletpassphrase RPC command to mint block only. In this unlocked wallet mode, one cannot send transaction through RPC command thus providing additional security to the wallet if hacker gains access via RPC.


Is there a cap on total money supply like Bitcoin’s 21 million?


There is no hard cap other than a 2 billion coin max put into the code for now. But that should not be interpreted as an approachable cap, as it might never get anywhere close to that. It should not be considered a hard cap either as it may get lifted but that’s likely not needed in a very very long time. Due to the nature of the mint rate design it’s not possible to predict a final limit as it depends heavily on market participation, as well as the influences between proof-of-stake minting and fee destruction (there may not even be a mathematical limit if minting continues to outpace fee destruction). What we do know is that the proof-of-work minting would slow down exponentially according to Moore’s Law (we are aware that Moore’s Law eventually would stop to apply), and proof-of-stake minting introduces 1% annual inflation in the future (but it starts from higher values). So generally speaking it is still a very low future-inflation design comparable to Bitcoin.


 


NovaCoin was the first PPC fork, but not a clone!

new versions ale coded standalone, not from new ver. of PPC.


major changes:


1. Scrypt chashing!

2. initial reward of 100 not 10000

3. slower reward drop

PPCoin cuts a half from reward for every 16x diff adjustment.

NovaCoin cuts a half from reward for every 64x diff adjustment.

4. POW difficulty adjusted for scrypt

5. POS difficulty adjusted for 100 times less coins.

6. ROI for POS changed to 0.05 coin per 1 coinyear [dynamic from 4.1]

FeatherCoin - New Litecoin based coin

FeatherCoin is a fork of Litecoin using its latest build.


I am a supporter of Litecoin and will be following Litecoin’s patches and releases. The Litecoin team is currently working on a newer release and this project will move with them.



One of Litecoin’s biggest advantages is the Scrypt-based hashing algorithm. This offers a different solution to Bitcoin, while still being able to run on GPUs. There are many Bitcoin forks using the original hashing algorithm, but with the advent of ASIC mining hardware, we are starting to see how much trouble they can cause. ASIC mining hardware is expensive, but outperforms GPU hardware and will eventually make GPU Bitcoin mining redundant.  Scrypt based crypto currency is safe guarded from the effects of ASIC mining.


Feathercoin has a block reward of 200 coins and will have a total of 336 million coins. This makes it four times that of LiteCoin, this is the same position that LiteCoin was set against BitCoin.



Default port is 9336 – Forwarding this port can help if you have connection problems

Default RPC port is 9337 – This is the port is point your miners towards if solo mining

2.5 minutes block target

504 blocks to retarget difficulty

41.4% maximum change on difficulty retarget

Block reward halves every 840,000 blocks

What is MinCoin?

MinCoin, or ‘Minimalist Coin,’ is a peer-to-peer crypto-currency based on the memory-heavy SCRYPT algorithm.


This particular algorithm affords enhanced protection against ASIC devices like the ones currently dominating the Bitcoin network.


Fast block time – Although they both utilize the same SCRYPT algorithm, MinCoin’s block interval of 1 minute is a full 2.5 times faster than Litecoin, and a full 10 times faster than the SHA-256-based Bitcoin. This means lightning-quick transactions and a more secure network.


Low Cap – Only 10 million MinCoins will ever be created, compared to 21 million total Bitcoins and 84 million total Litecoins.


Features of MinCoin – MinCoin will have a total of 10 million generated units.

MinCoin has one (1) minute block targets, which is 10 times faster than Bitcoin and 2.5 times faster than Litecoin! Each MinCoin block is worth two (2) new coins. Difficulty is retargeted with every 720 blocks.


MinCoin (MNC) – a minimalist version of Bitcoin optimized for CPU mining using scrypt as a proof of work scheme.


*Only 10 million coins total will be generated

*1 minute block targets for ultra fast transactions

*To encourage early adoption block values for first 3 days are :- 500 MNC, 100 MNC, 50 MNC

Peter Bushnell is the founder and creator of Feathercoin, one of the latest digital currencies. We talked with him to learn more about Feathercoin’s origins and how to best mine the currency.

While the origins of Bitcoin are shrouded in mystery, the founder of Feathercoin (FTC) says he likes transparency. Feathercoin is controlled from a house at the end of a terrace, in the sleepy Oxfordshire suburb of Arncott. The currency is the brainchild of Peter Bushnell, who until last month ran the IT department at Oxford University’s Brasenose College.

When he first joined the university, Bushnell spent the first few months trying to persuade the IT department to put in a firewall … and he continued that battle for the next 11 years. Now, he’s moved on. “I was keen for another challenge,” Bushnell says. “None of the projects going on there really enthused me.”

These days, Feathercoin is keeping Bushnell so busy that he feels like he hardly sleeps. He works full-time managing an altcurrency with a market cap that beats Freicoin and BBQCoin, and which is quickly catching up to Terracoin. That isn’t bad for a currency that launched only this past April 20th.

What is Feathercoin?

Feathercoin is based on Litecoin, a math-based currency that came to life in October 2011. Like Litecoin, Feathercoin uses a fundamentally different hashing algorithm than Bitcoin. Whereas Bitcoin is based on SHA 256, Litecoin and Feathercoin use Scrypt. That hashing algorithm is memory intensive, which makes it far more difficult to simply throw computing power at it by developing an ASIC. It gives CPU and GPU miners a better chance of mining the currency.

How/why was it developed?

Bushnell first dabbled in altcurrencies at the end of 2011, and became increasingly interested in the concept. He started by mining Solidcoin, but then switched to Litecoin. Back in the day, there was an enthusiasm about Litecoin which he loved. It was the underdog in a cryptocurrency world controlled by Bitcoin, he recalls. “When I started with Litecoin it was really the community that I thought was very engaging, because there was a certain amount of arrogance among Bitcoin users.”

He loved Litecoin so much that he mined 30,000 of them. However, he added, “People were taking their success for granted … I wanted a coin with four times the amount of coins, and I wanted to recreate the level of enthusiasm that we had in the first place.”

Eventually, Bushnell continued, “I thought there was room for something else.” That something was Feathercoin. He finally finished it while on holiday. “I came to the decision that I could either go back to work or pursue my hobby,” he says.

He gave away 2,300 litecoins as bounties to others in exchange for helping him to flesh out the Feathercoin project, and plugged himself into the project full-time. How did the bounties help the project? “I figured it would be a good way to rally the community,” Bushnell explains. “So really it was to get work done. And then we faced obstacles, as you do, along the way. Quite often [when] offering a bounty, people have come forward with a solution.”

Relationship to Litecoin

Members of the Feathercoin team include Peter “John” Manglaviti, who is organizing projects on the Feathercoin website, and Robert Hazinga (“Dreamwatcher”) a US-based cryptocurrency professional who used to make and repair PCs, but then got into arbitrage full time. He wrote the block explorer for FTC.

Who will use Feathercoin?

“We’d hope that eventually this would become something that’s fit for the mass public,” Bushnell says. “For consumers to use. The major problem is getting sort of cash into it. Getting real world money into bitcoins, which has made this whole thing live around with the techies more than anything else. You have to try quite hard. But there will be services that will be coming out that will make this whole thing much easier. There is a lot of money in it.”

Difficulties and hard forks



One of the biggest challenges for the currency has been the rising difficulty level. Bushnell has to find a balance between difficulty and popularity. If the coin gets too difficult too quickly, people might stop mining it. This is what caused him to hard-fork the currency on May 22nd, just over a month after its launch. Hard forks aren’t desirable in cryptocurrencies. Sometimes they happen accidentally, but some argue they are necessary.

“It happens when you decide that you want to make a structural change to the way that they’re generated,” Bushnell says.

“Normally, you’d hard-fork to introduce new features into a coin. But, in FTC’s case, it was to bring the difficulty down. “When smaller coins get mined to a high difficulty, we lose that profitability,” says Bushnell. “That’s what happens now, which is why so many coins are forking for difficulty.”

Best mining rigs

When asked about what hardware he would recommend for mining FTC, Bushnell said: “Well, the best card in my mind for the job is an AMD Radeon 7950. I don’t know if that is starter enough. It is pretty top of the shelf. You can get them for £215, which I think is a deal considering that you can squeeze just as much performance out of them as you can a 7970.

“You can get a 7970 up to kilo-hashes and a 7950 will run at [the] 650 point easily. At least, I found they do with a sort of tweaking. They are £100 less and don’t use as much power. That would be my entry level card …



“You need something with decent shade counts, and that’s what they have. Not as much as the 7970. And then you have the 7870 XT which is 1500 shaders, but they are very scarce in England. They seem very popular in the States, but I just can’t source them, and if you can source them, they are just as pricy as the 7950s. That’s if you’re in the know. It’s the 7870 if you’re in the know and in the States.”

Future of the altcoin landscape

With the wide variety of digital currencies appearing, we asked Bushnell how he saw the future unfolding and how these currencies might relate to one another.

“I see room for lots of cryptocurrencies,” he says. “We just need the correct solutions in place to support them well … You could have much more niche coins, which I think would be fantastic. A small group of people could drum up their own coin for changing between themselves with a root to an exchange. As long as you have some volume — as long as you’ve got some value — you have a viable currency.

“There is room for a lot more, but people aren’t really prepared to see a lot more. There is room for a lot of fun coins. You could have a Pokémon coin, a color collectible, or that sort of thing. There is a lot of room for coins in games as well … We had Linden dollars in the past with Second Life.”

What do altcoins need to succeed?



Clearly, digital currencies need much more infrastructure in place before they can achieve mainstream adoption. One part of reaching that goal, Bushnell believes, is getting around the irreversibility of digital currency transactions: “There are some major obstacles. I think the biggest one is, transactions with typical fiats are reversible. So people are loath to facilitate between the two. Once that obstacle is overcome, then we can see people adopt Bitcoin much more easily. And this will happen. In the States, they are rolling out bitcoin vending machines. It seems very smart. You go along and stick in your real-world money and out pops these little bitcoins which have a code in. So really that’s the sort of solution that we need to come up with.”

What is Feathercoin?

What is PPCoin?

PPCoin is an alternative cryptocurrency based on Bitcoin which was released on August 12, 2012. It is the first known implementation of a combined Proof of Stake/Proof of Work system.

As of April 14, 2013, PPCoin had a market cap of 29323 BTC (USD $2,932,300 equivalent), trailing the market cap of Bitcoin, Litecoin, and Namecoin.

Differences from Bitcoin



Proof of Stake

PPCoin’s major difference from Bitcoin is that it uses a proof-of-stake/proof-of-work hybrid system for coin generation. With this system, coins are generated based on proof-of-stake blocks in addition to proof-of-work blocks. Proof-of-stake block generation is based on coins held by individuals. In other words, someone holding 1% of the currency will generate 1% of all proof-of-stake coin blocks.

Potential for Increased Security

Proof-of-stake block generation could reduce the risk of 51% attacks for at least two reasons. First, the cost of acquiring 51% of all stake could in theory be much higher than the cost of acquiring 51% of all mining power, thus raising the cost of attack. Second, in a 51% stake attack the attacker’s investment would be directly at risk of losing value. By contrast, with a 51% mining attack the attacker would still own the mining hardware which could either be sold or used to mine a different cryptocurrency following the attack.

Energy Efficiency

Proof-of-stake blocks require minimal energy consumption. Thus, with PPCoin energy consumption would decrease over time as proof-of-work blocks become less rewarding and coin generation becomes increasingly based on proof-of-stake block generation.

Criticism



Centralized Checkpointing

At present, PPCoin is technically not decentralized as it still requires centralized checkpointing. This is to defend the network until it matures, enabling “a smooth upgrade path if critical vulnerability is found” during its growth period.[2] The developer has noted that based on trends of increasing market acceptance of PPCoin, centralized checkpointing is likely to be phased out later this year.

Premining

There have been some concerns that PPCoin may have been pre-mined. However, this does not appear to be the case, as an examination of the block explorer shows that the first block was mined at 18:19:16 UTC, whereas the coin software was released to the public at 17:57:38 UTC.

Release Protocol

It has been noted that the release of PPCoin did not follow the Alt-chain release RFC, which could have given early adopters a potentially unfair advantage. For example, the official announcement thread for PPCoin was posted two hours after the first block was mined. However, it should be noted that the release was first announced in a pre-release thread 9 days before mining began, and released in that same thread before the first block was mined.[8] Moreover, other efforts were also made to ensure fairness, such as a higher starting difficulty (256) to reduce the initial rush. Compared with other altcoin releases, PPCoin’s release can be considered fair. Litecoin, for example, was released with 4 days advance notice, a starting difficulty of 0, and two pre-mined blocks.


PPCoin is a cryptocurrency which is forked from bitcoin. PPCoin aims to achieve high energy-efficiency while keeping as much as the official Bitcoin properties as possible.


PPCoin works with Stake/Proof-of-Stake, this is a term referring to the use of the currency itself to achieve certain goals. PPCoin uses proof-of-stake to provide minting and transaction processing of place of proof-of-work. Unlike Bitcoin ppcoin does not require the use of energy to sustain the network. Proof-of-work currently remains the most practical way of providing initial minting of a cryptocurrency so it was decided to keep it as part of the hybrid design.


Untill v0.2, central checkpointing was a critical part of the protocol. The main purpose of this is to defend the network during the growth period and to ensure a smooth upgrade path if any critical vulnerabilities are found. Central checkpointing will slowly be weakened and should eventually removed from the coin.



Unlike Bitcoin there is no hard cap on the amount of coins that will be created. Bitcoin is limited to 21 million coins where PPCoin only has a hard cap of 2 billion coin in the code. There is no intention to limit the amount of coins that can be generated.


PPCoin mining


PPCoin is mined in the same way as Bitcoin. However merged mining is not available at the moment due to the differences in the block chains. It can be made possible if the block chain would be altered but if this is done, PPCoin is no different from Bitcoin. PPC would most likely be discarded by the community if the merged mining would start.


Just like bitcoin, it is exchanged through Peer to Peer networking (P2P), has its own blockchain, however there is a new addition to the Proof of Work generation of coins; this being Proof of Stake. Proof of Stake works alongside Proof of Work in the generation of coins, and provides most of the network security. Proof-of-stake is based on coin age and generated by each node via a hashing scheme bearing similarity to Bitcoin’s but over limited search space. This leads to the long term prospect of the Proof of Stake doing most of the work and hence only relies on the coin being in online wallets, as opposed to GPU, FPGA and ASIC farms eating up masses of electricity just to keep the network secure in many years to come. PPCoin is touted to be the only current long term energy efficient currency.



Some other variations on the code


The proof-of-work mint rate to be not determined by block height (time) but instead determined by difficulty, that is mining difficulty goes up, proof-of-work mint rate is lowered. PPCoin destroys transaction fees


History


PPCoin was launched by Sunny King and Scott Nadal on August 19th, 2012 where they wrote this white paper http://www.ppcoin.org/static/ppcoin-paper.pdf and started the PPCoin blockchain.
