Bleutrade vs Cryptocurrency Htmlcoin: Successful Double-Spend, Lack of Developer Response?

posted Jun 24, 2017, 6:59 AM by Ian Hervey

BY P. H. Madore on 22/06/2017

According to a recent document published by Bleutrade, there was a double-spend on the Htmlcoin chain against the exchange earlier this year. According to the exchange, they contacted the development team about implementing changes which could have prevented this from happening.

What the attacker essentially did was deposit with a transaction he intended to double-spend, and then withdraw good coins from the exchange, thereby basically doubling his supply of coins. As soon as he made the withdrawal, he republished the blockchain with a more-than 51% attack, making the coins now all go to his wallet, instead of any coins having ever been sent to the exchange, but only the exchange having sent coins to the wallet.

Bleutrade says this would not have happened if the Htmlcoin wallet were designed differently, and notes that other coins of a similar age have experienced similar problems. The document also addresses a lethargic development response. Even after the team submitted changes, the exchange informed them that these changes were not sufficient. The whole thing is problematic in that the exchange should simply implement insanely high deposit confirmation requirements. This is the only way for exchanges to respond to coins that have blockchain issuses, big coins included. Bad things can happen if you play it fast and loose, and in this case, they did.

Bleutrade wrote:

Html5coin blockchain experienced a double spend attack between April 25 and 26, 2017. This attack caused two large transactions with dozens of confirmations to be unduly erased from the current blockchain, causing an insolvency in the exchange. […] The double-spend attack is only successful if the attacker has more than 51% of the network’s mining power to be able to replace the current blockchain with another of his choice. Similar attacks have already occurred with Virtacoin, Ambercoin, Vertcoin, CannabisCoin and e-Gulden, this type of attack is becoming common with outdated coins and few miners and several exchanges are suffering because of this.

For their part, Htmlcoin’s team have warned people to only use Bleutrade, writing in an e-mail blast:

Our team is working hard on the following update: (a) Implement 10 minutes block (b) Implement 115 confirmations.

However, Bleutrade still came out with this document, although later after negotiations they re-enabled Htmlcoin deposits. It seems the Htmlcoin team did genuinely want to support Bleutrade in figuring out the best way forward. According to the trading page on Bleutrade, the developers have now created a new version of the wallet which will comply with their demands, and deposits have been re-enabled. Nevertheless, these problems could have been foreseen by either party, and something could have been done.

This author himself is working on an instant exchange, and one of the coins that is being implemented has been known to have serious blockchain issues. As such, the exchange will simply require 60 confirmations from that chain. With any luck, it will only encourage the chain to act more appropriately in the future. Htmlcoin will have to be treated in the same way by exchanges moving forward, and other coins should be forced to implement the same changes, such that these types of attacks not only become more rare, but ultimately, it would be best if they became impossible.

Htmlcoin wrote in a recent post on the subject:

HTMLCOIN is swapping this 2017 with a new feature that includes the many applications of “Smart Contracts” and the security provided by “Real-Time Checkpointing.”

All coins in the three (3) exchange sites are safe and will be swap to a stronger version, with all the latest features of the leading cryptocurrency in the market. This huge step that we are undertaking will make our coin relevant and responsive to the demand of the “Internet of Things.”

Current owners of HTMLCOIN will now be able to swap to at ratios between 1:1. Late swapper will be at the ratio of 1:2 or less, depending on the time. The further you swap from the scheduled date, the lower the swap ratio will be.

Cryptocurrency exchanges Bleutrade, YoBit, and CoinGather are currently preparing to facilitate the swaps.

So it seems that things have wrapped up neatly with this particular coin, but all coins will also have to undergo changes if they are going to remain in circulation.

Frequently Asked Questions & Guidelines for the Htmlcoin Swapping 2017

 

Who: All Htmlcoin Holders

What: Swapping old htmlcoin to the new htmlcoin.

How:  One to one ratio (1:1) during the specified swap dates. One to two or less ratio (1:2 or <) for late swappers. The further you swap from the scheduled date, the lower the swap ratio you will get.

When: After 75% Percent of all coins in circulation accounted in the exchange sites

Where: Exchange Sites and Manual.

Why: To upgrade coins specifications.

 

Exchange Sites: Currently, no one can withdraw, this is in preparation for the swap day. All traders can continue to trade and able to deposit.

 

>>>IF your coins are located on the Exchange Sites, you do nothing. The exchange will do it for you automatically.

 

>>> IF your coins are located in the wallet, you have to show proof:

  1. On the right side must show the latest transaction.

    1. Send am htmlcoin to any address to do this, we suggest sending one (1) htmlcoin or less.

  2. Take a picture with your finger in the photo pointing the amount.

    1. A screenshot is not acceptable.

  3. We may ask additional information, such as your wallet address, to see in the explorer the exact amount, as shown in the picture.

  4. You will be asked to email it to the specified email address, wait for more updates.

 

>>> IF your coins are located in the paper wallet, you must show the address.

 

Nota Bene: Old HTMLCOIN mined during or after the swap date will not be honored.

 

*These guidelines above may change anytime.

SPECIAL HTMLCOIN WORLD MEETING JUNE 17, 2017.

posted Jun 18, 2017, 5:13 AM by Ian Hervey   [ updated Jun 18, 2017, 5:40 AM ]

TOPIC: SPECIAL HTMLCOIN WORLD MEETING JUNE 17, 2017.

AGENDA: TO DECIDE THE DETAILS OF THE WALLET UPDATE AND RELATED MATTERS.

TIME: JUNE 17, 2017, AT 10:30 AM BRITISH SUMMER TIME (BST).

PARTICIPANTS:] ATTENDED BY 27 INDEPENDENT DEVELOPERS AND COMMUNITY MEMBERS.

COUNTRY OF ORIGIN: THE UNITED STATES OF AMERICA, THE UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND, THE REPUBLIC OF THE PHILIPPINES, THE PEOPLE'S REPUBLIC OF BANGLADESH, THE FEDERATIVE REPUBLIC OF BRAZIL, THE ISLAMIC REPUBLIC OF PAKISTAN, THE REPUBLIC OF SINGAPORE, ROMANIA, THE FRENCH REPUBLIC, THE UNITED ARAB EMIRATES (DUBAI), THE REPUBLIC OF COLOMBIA, THE UNITED MEXICAN STATES, THE REPUBLIC OF INDONESIA, THE SOCIALIST REPUBLIC OF VIETNAM, THE REPUBLIC OF INDIA, THE REPUBLIC OF BULGARIA, AND THE RUSSIAN FEDERATION.

WE AGREED ON THE FOLLOWING:

ABSTRACT

•    We decided that Blockchain will not be reversed as requested by Bleutrade but we offer a possible solution.

•    We invited a Cryptocurrency Expert and a Computer Science faculty to help us understand the technical problem.

•    We are implementing checkpointing for Htmlcoin to hinder and stop hacking risk and future attacks.

•    We are releasing an updated wallet.

•    We want to understand more about the Bleutrade Insolvency Enigma.

•    Summary of the meeting and Implications of our decision as a community.

DETAILS

1.    We, HTMLCOIN Developers and Community Members in attendance, decided that Blockchain will not be reversed from April 25, 2017, until the present date of this meeting.[/b]

1.1.    The request of Bleutrade to reverse the blockchain was not granted by the core team. However, we offer them a possible solution for their claim of insolvency of 5.6 Billion by swapping the claimed lost coin to a new coin. It is important to note that not all of their holdings are lost, if any. We are waiting for their response on this offer. See section 5 - 5.5 for more information about Bleutrade Insolvency Enigma.

1.2.   We are looking forward to resolving this issue of insolvency claim with Bleutrade because we were part of this exchange since their early days in 2014, Bleutrade is a family to us.

1.3.    We believe that reversing will do more harm than good. If the blockchain will be reversed, it will erase all 1 month worth of transaction, that would be a bigger disaster.

1.4.    If we reverse the blockchain this would mean that all transactions conducted from April 25, 2017, to date will be nullified, all transactions thereafter will turn to zero. Reversing the wallet is NOT an option.

2.    We invited a cryptocurrency expert, Peter Bushnell, a former constituent of The University of Oxford, and Zac Smith, a faculty of Computer Science of New Mexico University, to help us understand the extent of our coin’s technical problem.

2.1.    Peter Bushnell’s advised that checkpointing be added in the coin and that the blockchain should not be reversed. Zac Smith agreed on these recommendations as well. The two experts are instrumental in our present decision for the coin, moving forward.

3.    We are implementing checkpointing for Htmlcoin, as the new feature of the wallet to hinder and stop hacking risk and future attacks.

3.1.    Simply put, the checkpoint prevents attackers from replacing the existing chain with a different chain to protects against transaction reversal. Checkpoints are built into the Bitcoin code, they are defined as a block height and its hash, the Bitcoin software will only connect to chains with those checkpoints in.

3.2.    Automatic Checkpointing is real time checkpointing, rather than define them in the code they are broadcast from a node on the network. In the source code there will be a public key, only a node with a corresponding private key can send out checkpoints, that node will also need to configure a depth for the checkpoints, that is how many blocks there needs to be after a block before it is checkpointed, so a depth of 5 means that a block will be checkpointed when there are 4 confirmations for it making it 5 blocks deep from the top of the chain.

4.    We are releasing a new Wallets and Files.

4.1.     This is the location of the Windows Wallet: http://seed.htmlcoin.net/HTMLCoin-1.3.2.1-setup.exe

4.2     This is the location of the Mac Wallet: http://seed.htmlcoin.net/Htmlcoin-1.3.2.1-Mac.dmg

4.3     This is the Blockchain: http://seed.htmlcoin.net/htmlcoin_blockchain.zip

4.4.    This is our GitHub account: https://github.com/HTMLCOIN/HTML5

5.    The Bleutrade Insolvency Enigma.

5.1.    The Attacker Deposited 5.7 Billion to Bleutrade and Withdraw the coin.

5.2.    Bleutrade informed us that “The attacker DEPOSITED 5.6 Billion in Bleutrade, sold an amount to Doge and withdraw the remainder.”

5.3.    HTMLCOIN Team investigated and found out that the total amount stolen from the attacker in Bleutrade is 928440.36517198 DOGE. See the spreadsheet, https://docs.google.com/spreadsheets/d/1FOJC3ayvP2gV69QfddmLPuVb06OAqw2mWfoVVT02Hww/edit#gid=0

5.4.    Logic will dictate that the insolvency in Bleutrade should only be 928440.36517198 DOGE, not the 5.6 Billion HTMLCOINS as claimed by Bleutrade.

5.5.    Because of this Enigmatic Insolvency claim by Bleutrade, we are asking them to clarify why there is such a huge insolvency, given that the attacker deposited the amount of 5.6 Billion to Bleutrade, meaning Bleutrade do not own the 5.6 Billion HTMLCOIN in the first place. The 5.6 Billion is owned by the attacker.

5.6.    On June 8, 2017, Bleutrade informed us the GOOD NEWS that the attacker was denied by the network.

5.6.1.    Below are the 2 deposits deleted from the blockchain even after several confirmations:

5.6.1.1.    HTML5 c8d657812abc1779d924235e6938a5c35e7428f5916eec38c64ea34ec18217f2 4605383 2017-04-25 23:09:17 HRYCxScEBr8R4eLRc9zwsmU8jX8gvcoM6a 2947478457.86640000

5.6.1.2.    HTML5 9699446ff34e6224a177df2566c6503f791330256601c7126ad10ed225c61b3b 4604813 2017-04-25 16:16:14 HTENYcoKi3NYM13AhwrjzsEN9AGnVYYYui 2852036157.86640000

5.6.1.3.    Total: 5799514615.73279954 HTML5

5.7.    Activity and Identity of the Hacker.

6.    Summary of the meeting and Implications of our decision as a community.

6.1.    Reversing the blockchain will do more harm than good.

6.2.    Because we decided not to rollback the blockchain, all coins outside of Bleutrade, specifically in Yo Bit and Coin Gather, it will not turn to zero, they are legitimate.

6.3.    We have instructed Yo Bit and Coin Gather to resume trading.

6.4.    We are releasing an updated Windows Wallet, Mac Wallet, Blockchain File, and the HTMLCOIN account in GitHub.

6.5.    We understand that the Attacker Deposited 5.7 Billion to Bleutrade.

6.6.    That the attacker was denied by the network.

6.7.    That the 2 deposits were deleted from the Blockchain.

6.8.    That we need to understand more about the Bleutrades Insolvency Enigma and we are willing to cooperate in solving this issue.

6.9.    The attack that happened in Bleutrade is not an isolated case to HTMLCOIN. Other cryptocurrencies in Bleutrade were also a victim of a similar attack, such as Virtacoin, Ambercoin, et cetera.

6.10.    That we have the identity of the hacker.

6.11.    We are maintaining open communication to Bleutrade to explore possible solutions.

6.12.    Given with this experience, we are now implementing real-time checkpointing moving forward so that the will withstand possible attacks a feature that will make HTMLCOIN stronger in the future ahead.

HTMLCOIN going up since last month - but you would never know.

Hello everybody!

HTML5 Coin: I am no expert, but I AM a fast learner.

Screen Shot 2017-06-05 at 9.27.43 AM.png

Recently when I started getting back into crypto I had some coins that I kept from a few years ago, one of them was HTML5 coin. I had a ton of them. I was sad to see that the site had not been updated and half the links there were dead. There was no place to trade them except for Bleutrade and the price was next to nothing. 1 satoshi - no volume, nobody would buy them. Until, luckily, I happened to figure out, somehow, that HTML5 coin was also trading on the Dogecoin exchange there. Still very little volume and the price was even lower(!) than 1 sat, but at least I could dump the coin and use the money to buy some DGB, which I did. And boy oh boy did that pay off!!!

Screen Shot 2017-06-05 at 8.32.06 AM.png

But I couldn't help thinking about HTML5 Coin, sitting there so cheap. Especially after my DGB purchase. RDD and Verge also burning up the charts too! So I meandered back to Bleutrade and my jaw almost hit the floor. Since my dump fest, the price had literally skyrocketed from .001 doge to .009 doge. OMG!!!

![Screen Shot 2017-06-04 at 8.57.20 PM.png]

I immediately grabbed some doge and went to work buying up as much as I could. If you are interested, please use my link for Bleutrade. THANKS. bit.ly/BleuLink

I purchase my Bitcoin on Coinbase, not the cheapest place but I trust them. Here is my link for that bit.ly/RalphCoinbaseLink

Well the very next thing I get an email from the dev team that the HTML5 site has been updated(!!!!!) and that there is a new wallet coming out. Here is the email that I got:

Dear HTMLCOINERS,

www.htmlcoin.com website updates have been implemented. The team would like to thank the countless members who help us since 2014.

Do not buy or trade outside of Bleutrade until we update the new wallet in this coming couple of weeks.

PLEASE DO NOT MINE YET UNTIL UPDATE IS DONE.

All the best,

HTMLCOIN TEAM

The “crypto currency model” is done by consensus.
htmlcoin banner 2017.png

Will this coin be the next top volume? Maybe, maybe not, but this morning folks, DRUM ROLL PLEASE, I already doubled my money. In this environment, how many one to two satoshi coins stay there? Do your own research and take ownership of your own decisions. I am just some dude sitting in his pajamas reading stuff on the internet. Not a pro.

Screen Shot 2017-06-05 at 8.28.21 AM.png

As the saying goes, a word to the wise is sufficient. Take your shot and BE CAREFUL OUT THERE!!! And as always, pay it forward.

: )

HTMLCOIN volume is very high in our history at $68,000.00 plus.

posted Jun 5, 2017, 4:59 AM by Ian Hervey   [ updated Jun 5, 2017, 5:05 AM ]

Dear HTMLCOINERS,

Great news today!
  • We are now in 2 satoshis.
  • The volume is very high in our history at $68,000.00 plus.
We are growing exponentially. Thank you for your support!
