1  Alternate cryptocurrencies / Marketplace (Altcoins) / Android Wallet Creation Service - Lightweight, Electrum Based Android Wallets on: November 28, 2015, 12:28:48 AM
ALTCOIN ANDROID WALLET CREATION SERVICE



I am now (officially) offering my android wallet creation service to the public. The wallets I build are lightweight and based on Electrum. A local copy of the blockchain is not needed to perform send/receieve coins. Other android wallets need a local copy of the blockchain in order to work. Removing the need for the blockchain has several key benefits:

  • Always On: The wallet is ready when you are. No need to wait for the blockchain to catch up.
  • Improved Battery Life: Downloading and verifying the blockchain drains the battery life substantially, especially for coins that utilize complex algorithms like KGW/DGW. By not downloading the blockchain, we dodge this issue.
  • Reduced Storage Needs: The entire wallet takes up 6MB of space. Other wallets can use a hundred times this amount, or more, depending on their blockchain size.
  • Near Zero Data Usage: Cell phone data plans are expensive! Why waste your precious data downloading the blockchain? Data usage for this wallet is very low, measurable in the kilobyte range.

Other unique features include:

  • Bitcoin/Litecoin Support: In addition to supporting your coin, all wallets built will also have bitcoin/litecoin support, providing greater utility for your users while also strengthing your brand.
  • Ridiculously Secure: All keys are stored on, and never leave, your device. Your wallet can be encrypted with a password, to prevent malware and unauthorized users of your device (thieves!) from stealing your coins.
  • Easy Backups: All of your private keys can be retrived from a simple 12 word mnemonic, similar to Electrum. So, even if you lose your device, you can easily retrieve your coins.
  • Privacy: Transactions are broadcasted through an anonymization server, which hides your IP from prying eyes.

Other people are still offering android wallets based on Schildbach's old bitcoin mobile wallet (link), or even worse, straight up compiling a QT client for android. I'd strongly recommend you stay away from these types of android wallets. They are very heavy, consume a lot of battery + data, lack advanced security features, and are not very aesthetically pleasing. I'm not just saying this to drum up sales; if you're in the market for an android wallet, find someone offering a lightweight one, even if it's not me. It truly is a superior solution.


PRICING

I am asking 1 BTC for the creation of the Android wallet for your altcoin. This includes all necessary debugging, compatibility testing across multiple devices, and delivering the APK to you.

Since this is an electrum based wallet, it will require an electrum server customized for your altcoin in order to function. I can create and host an electrum server for your coin at a cost of 0.5 BTC per year. That works out to about Ä14 per month - a slight markup over my hosting cost of Ä10 per month.

So for the complete package, you're looking at a cost 1.5 BTC.


ORDERING

Ordering can be done easily through the order form at http://dev.cryptolife.net/order/altcoin-android-wallet/.

Alternatively, you can send me a PM, or contact me via email.
2  Alternate cryptocurrencies / Altcoin Discussion / List of burn addresses for altcoins (provably unspendable addresses) on: September 16, 2015, 02:44:07 PM
The following addresses can be used to burn coins. Burning is a method of effectively destroying coins such that they can never be spent again. Coins can be burnt by sending them to the following addresses, which are guaranteed to have no known or discoverable private key.

The reason the coins sent to these addresses are now gone forever is that the burn addresses are demonstrably made up addresses, instead of being created together with the corresponding private key that would be required to spend the burnt coins.

26 characters of each burn address, CryptoLifeDotNetBurnAddrXX, are so perfectly ordered as to be obviously specifically chosen. (The remaining 6 characters, like the last 6 characters of any address, are automatically calculated and serve as a safety check feature.) This guarantees that there is no known matching private key for this address. In other words, the chance of anyone guessing the private key to spend the burnt coin at that address is the same as the chance of guessing any private key for any other bitcoin address: practically zero.

Burn addresses can be used for many different purposes including provably fair distribution of a new currency, premine destruction, and more.

Below are burn addresses for the 27 most common address prefixes. Please use the one that suits your coin. For example, LiteCoin addresses start with ĎLí so you would choose the corresponding address below.

5  Alternate cryptocurrencies / Altcoin Discussion / BitcoinXT and You Ė What Every Bitcoin Holder Needs To Know on: August 19, 2015, 03:37:54 PM
http://cryptolife.net/bitcoinxt-every-bitcoin-holder-needs-know/

By now, Iím sure youíve heard about the ongoing block size war. For the few of you who have been living under a rock, Bitcoin has been rapidly approaching itís hardcoded 1MB block size limit, and an all out war among core developers, pool operators, and bitcoin companies has erupted. BitcoinXT is the first shot fired in that war. It has the potential to destroy not only Bitcoin, but arguably, also itself. But, before we discuss that, letís briefly touch on the powers at play here and their stance. Most involved can be divided into one of four distinct groups, they are:

Against BitcoinXT. Against block size increase (for now)

This group is against any change to the protocol that would result in a hardfork. Their reasons are varied. Arguably, the most influential entity in this group are some of the Chinese pool operators, who feel larger that blocks would put them at a significant mining disadvantage due to current network conditions. They may be more receiving to such a fork in the future when networking conditions are more favorable.

Against BitcoinXT. Against block size increase (period)

This group wants nothing to do with a block size increase. To them, the block size issue is not an issue at all. Their view of Bitcoin is that it should only be used to remit large amounts of money. Smaller amounts should be settled either offchain or on sidechains. This way, the network need not be forked. Another common concern among this group is that if Bitcoin scales up, it will become more centralized.

Against BitcoinXT. For block size increase

This group wants to increase the block size in the near-term future, but believes that BitcoinXT is the wrong way to go about it. They view BitcoinXT as a hostile takeover by a minority group.

For BitcoinXT

Self explanatory. This group believes that the debate has gone on for long enough. They want their larger blocks, and they want them now. This group believes that a minority influence has been preventing Bitcoin from growing.

Distilling it down

That is a very basic overview of what is going on. Several articles could easily be written about each groupís viewpoints, and where they hope to see Bitcoin in 5 years. I donít want to delve into that, but if it interests you, here are some good starting points: 1, 2, 3.

Interestingly enough, Satoshi (or at least, someone pretending to be Satoshi) has weighed in on the issue with some strong words, going so far as to say he would ďdeclare Bitcoin a failed projectĒ should BitcoinXT take hold. Ouch. Satoshi has used this email in the past and it has been validated within the past month, so this comment was either made by him, or someone who managed to hack the account. Either way, regardless of the posterís true identity, the post makes a powerful statement.

Getting to the point


Putting all the politics here aside, the Bitcoin ecosystem really has two powers at play: the mining entities and the economic entities. Interestingly, each derives itís power from the other. The miners mine because the economy give their efforts value. The economy functions only because of the security provided by the miners. This is a very delicate balance, and a disturbance to either side could cause a great deal of harm to Bitcoin.

BitcoinXT currently lacks consensus, but, at the end of the day, it is miners that control whether or not XT takes hold. But, even if BitcoinXT was supported by the majority of miners, this does not mean that the economic powers will follow suit. What if some big exchanges or companies like Bitpay refused to support BitcoinXT? What about the users? Will every Bitcoin user and company migrate over to XT just because the miners say so? Likely not. The uncertainty and panic that this rift would cause would be unlike anything Bitcoin has ever seen before. Trust in cryptocurrency would be absolutely shattered, and it would take years to recover from this doomsday scenario, if recovery were even possible. Iíd go as far to say that it could very well put Bitcoin in an early grave.

With how much disagreement there currently is, it would be impossible for XT to experience a clean switchover. The ecosystem is far too fragile to able to deal with that. For that reason alone, I believe that XT is not even worth considering.

What the fork?

A lot of people donít understand what will happen when XT forks off, or the implications it will have for them. Letís start by visualizing the situation using the wonderful mspaint:



BitcoinXT is currently compatible with bitcoin (and will remain so until it has 75% of mining power), and is currently represented by the blue line (as is bitcoin). Should XT ever attain itís 75% majority, the block size will be raised to 8MB. When XT creates a block that is >1MB (represented by the yellow dot), it will fork off and create itís own network (represented by the orange line). Since Bitcoin only recognizes blocks that are <1MB as valid, this block will be discarded. Bitcoin will continue along it's own path, the blue line. The two networks are now entirely independent and incompatible with each other.

This creates some interesting and complex scenarios. Any bitcoin held in an address prior to the fork block is not only bitcoin, but also bitcoinXT. This is where things get murky. Mismanagement of addresses or certain types of transactions could result in the effective loss of bitcoin and/or bitcoinXT. Should XT ever come to fruition, bitcoin users would have to be extra careful in order to make sure that they are not accidentally destroying their XT, as it will hold some value. Along this line of thinking, there is another problem to worry aboutÖ Exchanges.

The exchange problem

Itís become quite commonplace for users to relinquish control of their coins over to a third party, such as an exchange. For these users, BitcoinXT will be their undoing, should it ever take hold. Because they do not control their private keys, they would own zero BitcoinXT. Whether or not they could claim XT would be at the mercy of the exchanges. Itís not too difficult to imagine a scenario where an exchange, for one reason or another, refuses to distribute XT. They could easily argue that users deposited only BTC, and are therefore not entitled to XT. Maybe they just donít want to deal with the headache that properly distributing XT would cause. Or, more simply, perhaps they donít support XT, and refuse to dole it out as a form of defiance.

The threat of XT is very real. As of last week, 44% of hashpower is currently voting to support 8MB blocks. Just yesterday, the first XT block was mined on the mainchain. For XT to take hold, 750 of the past 1000 blocks need to vote in favor of XT, so this is far from damning. However, those of you holding BTC on an exchange should take this as a wake up call, and pull your money out into an address that you control. If you donít, you face the possibility of losing ALL of your investment. Even disregarding the XT, holding coins in an exchange is a bad idea, as evidenced by Mt Gox and several others before it.

If thereís one takeaway from this article, it should be that holding coins on an exchange is a very, very bad idea.

Conclusion


For the above reasons, I do not think that BitcoinXT is the way to go. I am of the opinion that the block size limit needs to be lifted eventually (Mooreís law will see that processing massive blocks becomes trivial), but now is not the time, and XT is not the way.

11  Alternate cryptocurrencies / Altcoin Discussion / [ANN] CryptoLife UPWG - Universal Paper Wallet Generator on: December 27, 2013, 02:37:53 AM
Here's a universal paper wallet generator forked from bitaddress. If you set the corresponding decimal version, it'll let you generate a paper wallet for any altcoin out there. The decimal version refers to the the letter/number that a particular coin's address starts with. For example:

LiteCoin addresses start with L. So, the decimal version is 48.
NameCoin addresses start with n or m. So, the decimal version is 111.

The rest should be self explanatory. There's a few coins it won't work with, but ~99% of coins are compatible. This is a BETA and you should do the proper testing before sending any money to these addresses.

Long story short, some of my coins got lost in transit to one of the chinese exchanges (okcoin). I'm not a native chinese speaker and don't particularly feel like dealing with google translate.

Accordingly, I am seeking a middleman to deal with okcoin's support and get the funds credited to my account. Help me resolve this issue, and I'll reward you for your time. PM me for more information.
13  Alternate cryptocurrencies / Altcoin Discussion / [ANN] CryptoLife.net - Hard hitting cryptocurrency news and analysis on: September 29, 2013, 08:38:09 PM
I'm proud to announce the launch of CryptoLife. A hard hitting, unbiased source for cryptocurrency news and analysis.

The altcoin scene right now is the wild west. This forum is full of various shills trying to sell you whatever coin they have a stake in. Objective, unbiased information is impossible to find. Even the so called "news sites" offer little more than fluff; nothing of real relevance. With over 100 altcoins out there now, the average investor is lost in a sea of uncertainty, and doesn't know where to begin. Many get tricked by the shills into making poor investment decisions. CryptoLife represents my attempt to inject some sanity back into the altcoin community. The three main goals will be:

1. Bring transparency to the altcoin scene through objective and unbiased analysis
2. Guide new investors away from the scams perpetrated on this forum
3. Provide articles and discussions that will engage even seasoned investors

I've been involved in altcoins for the past 2 years, so I trust you will find my perspective to be interesting. I plan on partnering with other respected members of the community and bringing you content from them as well. One big name developer is already on board, stay tuned for more information on that. If you're interested in writing for the site, shoot me a PM.

15  Bitcoin / Development & Technical Discussion / error: txNew does name not a type (.1 BTC reward for solution) on: June 10, 2013, 03:12:33 PM
As a proof of concept, I'm trying to make an altered client that makes the genesis block spendable. I know this can be done with addUnchecked by sending it the TX and the block hash. I've started by trying to recreate the genesis block TX by pulling this code from InitBlockIndex:

Code:
       // Genesis block
        const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks";
        CTransaction txNew;
        txNew.vin.resize(1);
        txNew.vout.resize(1);
        txNew.vin[0].scriptSig = CScript() << 486604799 << CBigNum(4) << vector<unsigned char>((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp));
        txNew.vout[0].nValue = 50 * COIN;
        txNew.vout[0].scriptPubKey = CScript() << ParseHex("04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef3 8c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f") << OP_CHECKSIG;

But it doesn't work. Thoughts?
16  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] i0coin - Back from the dead on: June 03, 2013, 10:58:15 PM

For those of you who don't know, i0coin was one of the older alternate cryptos that had a decent backing before being abandoned by it's developer. Among other issues, a crippling memory leak eventually made the client unusable and the coin died.

I'm currently in the process of fixing all these issues and bringing this coin back to life. To that end, I need people who still have the i0coin blockchain to help me beta test the new client. Inquire if interested!

Disclaimer: I own zero i0coins so this project is at the low end of my priorities list.
