The events of a SIM swap attack (and defense tips)

Posted this on Coinbase and someone recommend it also be posted here. The information below on an attempted SIM swap attack was pieced together through a combination of login and security logs, recovering emails initiated by the attacker that were deleted and then deleted again from the trash folder, and learning from AT&T’s fraud representatives. The majority if this is factual, and we do our best to note where we are speculating or providing a circumstantial suspicion. TLDRs at the bottom.
The full story:
We were going about our business and received a text from AT&T that says “…Calls & texts will go to your new phone/SIM card. Call 866-563-4705 if you did not request.” We did not request this, and were suspicious that the text itself could be a phishing scam since we searched the phone number and it wasn’t overtly associated with AT&T. Thus, we tried calling AT&T’s main line at 611 but all we hear is beep beep beep. The phone number is already gone. We use another phone to call AT&T and at the same time start working on our already compromised email.
While we didn’t see everything real time, this is what the recovered emails show. In less than 2 minutes after receiving the text from AT&T, there is already an email indicating that the stolen phone number was used to sign into our email account associated with Coinbase. 2 minutes after that, there is an email from Coinbase saying:
"We have received your request for password reset from an unverified device. As a security precaution, an e-mail with a reset link will be sent to you in 24 hours. Alternatively, if you would like your password reset to be processed immediately, please submit a request using a verified device.
This 24 hour review period is designed to protect your Coinbase account."
This is where Coinbase got it right to have a 24 hour review period (actually a recovery period) before allowing the password to be reset. However, the attackers knew this and planned to steal the second email from Coinbase by setting email rules to forward all emails to a burner address and also have any emails containing “coinbase” re-routed so they don’t appear in the Inbox. 5 minutes later, they request a password reset from Gemini and the password was reset to the attacker’s password within a minute after that. The next minute they target and reset DropBox’s password followed immediately with Binance. Less than 2 minutes later, an email from Binance indicates that the password has been reset and another email arrives a minute later indicating a new device has been authorized.
It’s at this point that we begin locking the attacker out by (1) removing the phone number as 2FA (2) changing the email password, (3) and three forcing a logout of all sessions from the email. There was a bit of back and forth where they still had an active login and re-added the stolen phone number as 2FA.
They added only one more password reset to a gaming account that was not deleted. I can only suspect that was a decoy to make it look like the attack was directed at gaming rather than finances.
The Gemini and Binance accounts were empty and effectively abandoned, with no balances and inactive bank accounts (if any), and no transactions in 1-3 years. DropBox had no meaningful files (they probably look for private keys and authenticator backups) and the phone number they stole from us was suspended, so as far as the attacker is concerned, there is no meat on this bone to attack again… unless they had inside information.
This is where I suspect someone internal at Coinbase receiving wire deposits has been compromised in tipping off ripe accounts – accounts with new and somewhat large balances. We had completed a full withdrawal of funds from Coinbase earlier in the year, and had a balance of less than $20 heading into May. Deposits to Coinbase staggered in to get above six figures through mid-May then stopped. The attack occurred 7 days after the last large wire deposit was made to Coinbase.
From the perspective of an attacker that had no inside information, we were a dead end with abandoned Gemini and Binance accounts with zero balances and stale transactions, no DropBox information, and the suspended phone number access. Our Coinbase deposits were known to no one except us, Coinbase, and our bank. We were also able to stop the hacker’s email forwarding before Coinbase’s 24 hour period to send the password reset, so this one didn’t work out for the attackers and it would make sense for them to move on to the next rather than put efforts into a second attack only for Coinbase - for what would appear to be a zero-balance Coinbase account based on the other stale accounts.
Then…23 hours and 42 minutes after the first attack, another message from AT&T “…Calls & texts will go to your new phone/SIM card. Call 866-563-4705 if you did not request.” Here we go again. We had been confident in AT&T’s assurances that our account had been locked and would not be SIM swapped again, so we unwisely added the phone number back to our email account as a backup (it’s now removed permanently and we use burner emails for account recovery like we should have all along).
Upon seeing that our phone number had been stolen again I knew they were after the Coinbase reset email that was delayed by 24 hours from Coinbase as part of their security. We did 4 things within 2 minutes of that text: (1) removed the phone number again from the email account – this time for good, (2) market sell all Bitcoin on Coinbase, (3) withdraw from Coinbase, (4) have AT&T suspend service on the phone line.
In speaking with AT&T, they were floored that our SIM would be transferred again in light of all the notes about fraud on the account and the PIN being changed to random digits that had never been used by us before. Based on the response of disbelief from AT&T on the second port, I suspect that this attack also involved a compromised AT&T employee that worked with the attacker to provide timely access to the Coinbase password reset email. Apparently, this has been going on for years: https://www.flashpoint-intel.com/blog/sim-swap-fraud-account-takeove
with phone carrier employees swapping SIMs for $80s a swap.
Remember that most of this was hidden in real time, and was only known because we were able to recover emails deleted from Trash by the attacker.
Since we require any withdrawals to use Google Authenticator on Coinbase, our funds may have been secure nonetheless. However, under the circumstances with attackers that were apparently working with insiders to take our phone number twice in attempts to steal Bitcoin, and it being unknown if they had additional tools related to our Google Authenticator, we decided it was safer on the sidelines. The coins were held on the exchange for a quick exit depending on whether Bitcoin was going to break up or down from $10,000. A hardware wallet is always safest, but we were looking to time the market and not have transaction delays.
For some some security recommendations:
AT&T: If you are going to send a text saying that calls and texts are moving to a new number, provide a 10 minute window for the phone number to reply with a “NO” or “STOP” to prevent the move. This can escalate the SIM dispute to more trusted employees to determine who actually owns the line. Don’t let entry level employees swap SIMs.
Coinbase: Do not default to phone numbers as 2FA. Also, if someone logs in successfully with the password before the 24 hours are up, the password is known and there is no need to send the password reset email again for attacker to have forwarded to them. At least have an option to stop the password reset email from being sent. We did not tag our account at Coinbase with fraud because of the stories of frozen funds once an account is tagged. I’m not sure what the solution is there, but that is another problem.
Being a trader, it would be nice to think of Coinbase as any other type of security brokerage where your assets are yours (someone can’t steal your phone number and transfer your stocks to their account). We fell into that mindset of security, yet this experience has reminded us of the uniqueness of cryptocurrency and the lack of custodial assurance and insurance from exchanges because of the possession-is-everything properties of cryptocurrency.
As many have said before, 2FA with a phone number quickly becomes 1-factor authentication as soon as that phone number is associated with password recovery on your email or other accounts. Our overall recommendation is to avoid having a phone number associated with any recovery options across all your accounts.
TLDR on the process:
Scammers will steal your phone number (in our case twice in 24 hours) and use your phone number to access your email and accounts. They will use your email to reset passwords at financial accounts and file hosting such as DropBox. They will then use that combination to transfer any assets they can access from your accounts to theirs. They will do their best to hide this from you by
(1) not resetting your email password so as to raise suspicion,
(2) immediately delete any password reset emails you may receive from financial accounts to hide them from you,
(3) attempt to forward all emails sent to your address to a burner email, and
(4) set email rules to forward emails containing “coinbase” to an email folder other than your Inbox so that you don’t see the transactions and password reset emails that arrive to your inbox.
TLDR on defense tips: If your phone stops working or you receive a text of your number being ported do the following as soon as possible:
(1) log into your email account(s) associated with your financial accounts and remove your phone number as 2FA immediately
(2) change your email password,
(3) force a logout of all sessions from your email (at this point you have locked them out), then
(4) check your mail forwarding settings for forwards to burner addresses,
(5) check your mail rules for rerouting of emails from accounts such as Coinbase, and
(6) call your carrier to have them suspend service on your lost phone number and ask them to reinstate your SIM or get a new SIM. This will require a second phone because your personal phone number has been stolen.
We hope this helps some others be safe out there in protecting their coins. The more we know, the more we can protect ourselves. Wishing you all the best!

HUOBI EXCHANGE REVIEW

ABOUT HUOBI :
Huobi is a cryptocurrency exchange founded in China in 2013. Currently, Huobi is based in Singapore because this country has friendlier cryptocurrency regulations. The company is registered in Seychelles. Before leaving China due to a cryptocurrency ban, the exchange was responsible for 90% of Bitcoin trading volume in this country. Now Huobi is an international platform with offices located in Singapore, Hong Kong, the United States, Japan, and Korea. In China, the company provides blockchain consulting services. Huobi has sub-exchanges: Huobi Korea, Huobi US, etc. Huobi Global is the biggest Huobi exchange. In November 2019 Huobi Global had to shut down all the accounts belonging to the US customers due to strict cryptocurrency regulations of the USA. This exchange is one of the top 50 cryptocurrency exchanges by trade volume. On the Coingecko chart of exchanges, Huobi Global occupies the third position. The exchange has more than 500 markets and supports over 220 cryptocurrencies. As Huobi provides an option to buy cryptocurrency with fiat money, this exchange is a gateway for people who enter the cryptocurrency world .

FEATURES :
Huobi Global has a really wide range of functions. First off, this exchange provides an opportunity to buy cryptocurrencies with fiat money using a credit card and other payment means. This option is delivered in the over-the-counter trading section (OTC). There is a menu line in the upper part of the website. It begins with "But Crypto". That's where one can see the OTC offerings provided by Huobi. One can buy or sell the following currencies: Bitcoin (BTC), Ether (ETH), Tether (USDT), EOS, XRP, Litecoin (LTC), Huobi Token (HT), Huobi stablecoin (HUSD), and Bitcoin Cash (BCH). Please note, that there are not so many offerings especially for certain currencies. Normally there are many options for buying BTC or USDT. The prices and payment methods vary from one trader to another. You can pay with a credit card, some traders accept payments via Western Union, AliPay, and other services.
There is a cryptocurrency exchange with hundreds of crypto-to-crypto pairs. The exchange supports market, limit and stop-limit orders. It gives traders some control over the situation and helps to secure the assets from trading in loss to some extent. In general, the exchange interface of Huobi is quite generic.
Those who have experience of trading on several other exchanges will find the interface familiar. It has a trading view with a candlestick chart on the left and the list of orders updating in real-time on the right. Under the charts, there is an order history. Under the list of market trades, there is a section where users can place orders. The candlestick chart is powered with numerous analysis tools and indicators.
What makes Huobi Global more attractive for traders is the support of margin trading. In all margin trading pairs the currencies are traded against Tether (USDT). There are 6 cryptocurrencies that can be traded with x3 leverage: Bitcoin (BTC), Bitcoin Cash (BCH), Litecoin (LTC), XRP, Ether (ETH), and EOS.
Huobi Global is aimed to provide service both to small investors and institutional traders. That's the reason why the platform offers institutional accounts with special opportunities for corporate customers. Among these features, there are colocation options and other tools that provide the opportunity of seamless high-frequency trading. Additionally, institutional accounts can get special OTC loans.
One more feature is trading derivatives. Huobi provides two separate interfaces for that purpose: Swap trading and Futures trading platforms on Huobi DM. Moreover, it is possible to participate in IEO trading via the Huobi exchange. This feature requires the use of the Huobi Token.

ASSETS AND INSTRUMENTS:
As mentioned, there are two types of instruments that you can trade on the Huobi derivatives platform. These are your traditional futures as well as the perpetual swaps or futures.
With these instruments, you are trading crypto on margin. This means that they are leveraged and your exposure is often many multiples of the amount that you have put down as collateral.
Now that we have a brief understanding of leverage, let’s take a look at the instruments on offer at the Huobi exchange.
Futures are instruments that allow the holder to buy or sell some asset in the future. Essentially, you are trading some future price of the instrument on the chose delivery date. In terms of expiry dates, they have weekly, bi-weekly and Quarterly which settle every Friday. In terms of expiry dates, they have weekly, bi-weekly and Quarterly which settle every Friday. When it comes to the specifics of the contract, they differ according to which asset is being traded. You should also take a look into the contract specifics in the Huobi docs. This includes such information as the index reference for the prices as well as your last trading price. The latter can only be done up till 10 minutes before the expiry.
Perpetual swaps are leveraged instruments that do not have have a delivery date. They are marked to market everyday and settle 3 times a day. They are sometimes also called “perpetual futures” at other exchanges.
The reason that they are called “Swaps” at Huobi Derivatives is because you are swapping the returns of one asset for the returns of another. Here, you are swapping crypto returns for returns on the US dollar.
At Huobi DM, the Perpetual swaps have leverage up to 125x and they are written on 5 different assets. These are Bitcoin and Ethereum with other coins to be added soon.

HUOBI APPS:
Huobi mobile app for iOS and Android are available. Similarly, the Huobi mobile app features most of the functionalities available on the web platform also. You can even complete tasks like account registration and verification directly via the app. In Google Play, the Huobi Global app has an average rating of 4.1 stars out of 3,730 reviews. However, in December 2018 and January 2019, some users have said that the Android app won’t let them login due to an error with Captcha. On the Apple App Store, Huobi boasts an average rating of 4.9 stars out of over 4,800 reviews.

API :
For those of you who are programmers, you will be happy to learn that Huobi global API can be used on the Futures and Swap markets.
There is both a websocket as well as a REST version available. It is suggested that you use the REST for one off operation to trade and withdraw. You should use the websocket for market data & order updates. You should also note that you can be a market maker on through the API.
If you want to start using the API then you will to get yourself an API key. This can easily be done in the API management of your account dashboard. Here you can select whether you would like it to be a read-only, Withdraw or Trade. You can also bind an IP address to this API so you can ensure than no other person will use your account even if compromised.

HUOBI FEES :
Huobi has a 0.2 % fee that applies to both market makers and takers for amounts between $0 and $5,000,000 over the course of a 30-day period. In comparison, other top exchanges like Binance have 0.1 percent fees. Actually, it has a fair trading fees structure and easy to remember also. Meanwhile, GDAX has 0.3 percent fees.
In January 2019, Huobi Global launched a tiered fee structure that significantly reduces fees for higher-volume traders. This is relatively competitive when compared to other exchanges. Users also have the option to reduce trading fees on Huobi by becoming a VIP member. This involves paying a monthly payment of HT, which varies depending on the membership level (1-5).
Like most exchanges, Huobi has no fees on deposits. However, Huobi does have withdrawal fees minimums that vary from coin-to-coin. For example, withdrawing Bitcoin (BTC) costs 0.001 BTC, with a minimum withdrawal amount of 0.01 BTC. For Tether (USDT), the flat fee is 5 USDT. And the minimum withdrawal amount is 20 USDT. Overall, the meaning- Huobi fees are generally higher than most exchanges for lower withdrawal amounts. A few exceptions exist. For example, TUSD has a withdrawal minimum of $20 but a withdrawal fee of only $2.

IS IT TRUSTWORTHY?
In contrast to other exchanges, Huobi receives a favorable score. First of all, it is incorporated and operated from Singapore. As we all know crypto regulations are advanced there. And promote blockchain startups always. Second, Huobi does provide users with multiple ways to safeguard their accounts. Although it is not enough. Essentially, 2-factor authentication is available using both SMS and authenticator apps. The platform does not require any special confirmation if the account is logged into from an unfamiliar IP address or location. There is no option to whitelist addresses for asset withdrawal, allowing funds to be sent to any address input. Furthermore, Huobi was never hacked. Even though they do present a lucrative target for attackers. Meaning, Huobi has adopted a decentralized exchange structure, which helps to resist DDOS attacks. And we believe the exchange takes these threats seriously and does everything in their power to protect the exchange from hackers. Also, Huobi does store user funds in cold storage to restrict access to them. Actually, the exchange stores around 98 percent of funds in cold wallets.

SUPPORT :
Something else that is crucial to the entire trading experience is the level of support that the exchange provides. There is nothing more frustrating than having to wait hours for response from support.
When it comes to Huobi, there are actually quite a few options to reach their customer support. Perhaps the quickest and most effective way is through their live chat function. Firstly, they will try to help you with the available resources. If that does not work then you can reach out to a live agent.

CONCLUSION:
So, in summary. We really liked the Huobi futures products. It is not only highly functional but is also secure and leverags the expertise that the team have at the main Huobi exchange.
For the futures instruments, there is a decent range of assets and leverage. Markets are also pretty liquid and these are all traded on a simplistic yet technically able trading platform. It’s also great that you can trade on PC programs and mobile apps as well.
When it comes to security, they have taken all of the same precautions that are used on the main exchange. Their 20,000 BTC strong insurance fund keeps them well protected and they have not had a single clawback of trader funds since their inception.
Yes, there are areas for improvement but the exchanges is still evolving and building out functionality. One can only hope that they take trader suggestions into account.
So then, is it worth considering?
Well, if you are looking for a highly functional and secure futures exchange that is backed by one of the biggest names in the business, then it is well worth a try.

How was $24 million in bitcoin stolen from someone using Google Authenticator

https://www.wsj.com/articles/he-thought-his-phone-was-secure-then-he-lost-24-million-to-hackers-11573221600
Per the above story (open in incognito mode to avoid paywall), Terpin was using Google Authenticator:
"Mr. Terpin believes employees at an AT&T authorized dealer handed hackers control of his phone number, and those hackers found a way into his digital wallets by breaking into accounts of his that couldn’t be protected by Authenticator.
“On a scale of 1 to 10, I’d say my security protections were a 9.8 or higher,” he said. “But these hackers, all they do is they sit around in a basement and figure out ways of hacking people.”"
The first lesson is to not leave $24 million in hot storage, but if you're in the process of buying or selling bitcoin for fiat online you will eventually be somewhat vulnerable. So I'm wondering, how would a hacker get into say a Binance or Coinbase account of someone who has Google Authenticator enabled (which both support)? The only way I can think is that the hacker would impersonate Terpin and contact Binance/Coinbase and say they lost their phone and need to recover the account. I believe this method takes several days at least during which Terpin would know his phone was stolen and he'd be able to at least call Binance/Coinbase and tell them to freeze his account. Is something not adding up?

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).
Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.
Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.

Conclusion

Like other cryptocurrency exchanges, Binance grew significantly in 2017 due to increased interest in cryptocurrencies and a subsequent influx of new users across the space. This growth came with some growing pains, and some Binance users have complained about slow and/or lackluster customer support on Binance’s side.
Moreover, Binance’s contact options are limited, with users not being able to contact Binance in traditional ways, such as via telephone.
Regardless, user reviews of Binance’s support don’t seem to be terrible (when compared to that of other exchanges) and for now, users can submit an email request to contact Binance or reference Binance’s support page or social media pages for more information.

Update TKEYSPACE 1.3.0 on Android

Update TKEYSPACE 1.3.0 on Android

https://preview.redd.it/6w93e0afttx41.png?width=1400&format=png&auto=webp&s=c00989612ec2d52eb522405e6b6a98bf875e08bb
Version 1.3.0 is a powerful update to TkeySpace that our team has been carefully preparing. since version 1.2.0, we have been laying the foundation for implementing new features that are already available in the current version.
Who cares about the security and privacy of their assets is an update for you.
TkeySpace — was designed to give You full control over your digital assets while maintaining an exceptional level of security, which is why there is no personal data in the wallet: phone number, the email address that could be compromised by hackers — no identity checks and other hassles, just securely save the backup phrase consisting of 12 words.

Briefly about the TkeySpace 1.3.0 update :

  • Code optimization and switching to AndroidX;
  • New section-Privacy;
  • Built-in TOR;
  • Selecting the privacy mode;
  • Selecting the recovery method for each currency;
  • Choosing the address format for Litecoin;
  • Enhanced validation of transactions and blocks in the network;
  • Disk space optimization;
  • Accelerated syncing;
  • Checking “double spending”;
  • The bloom filter to check for nodes;
  • Updating the Binance and Ethereum libraries;
  • A function to hide the balance;
  • Advanced currency charts;
  • Access to charts without authentication;
  • News section;
  • Browser for Tkeycoin;
  • Independent Commission entry for Bitcoin;
  • New digital currencies;
  • Digital currency exchange tab.

Code optimization and switching to AndroidX

A lot of work has been done on optimizing the code to speed up the application, improving the logic, synchronization speed, calculating the hash of cryptocurrencies, and successfully switching to AndroidX.

https://preview.redd.it/h3go5tzgttx41.png?width=1100&format=png&auto=webp&s=bf311efc73e3577c80f06a21d6b9317bb93ae989

New section: Privacy

  • Enable Tor;
  • Blockchain transaction (the selection of the privacy mode);
  • Blockchain recovery (choosing a recovery method);
https://preview.redd.it/iydfwuhittx41.png?width=1080&format=png&auto=webp&s=2ce7c489d893a2ab6b9d6fede57d8b94404edcfb

TOR

Starting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies.

https://i.redd.it/kn5waeskttx41.gif
Tor is a powerful privacy feature for those who own large assets or live in places where the Internet is heavily censored.
Tor technology provides protection against traffic analysis mechanisms that compromise not only Internet privacy, but also the confidentiality of trade secrets, business contacts, and communications in General.
When you enable TOR settings, all outgoing traffic from the wallet will be encrypted and routed through an anonymous network of servers, periodically forming a chain through the Tor network, which uses multi-level encryption, effectively hiding any information about the sender: location, IP address, and other data.
This means that if your provider blocks the connection, you can rest easy — after all, by running this function, you will get an encrypted connection to the network without restrictions.

https://preview.redd.it/w9y3ax4mttx41.png?width=960&format=png&auto=webp&s=972e375fc26d479e8b8d2999f7659ec332e2af55
In TOR mode, the wallet may work noticeably slower and in some cases, there may be problems with the network, due to encryption, some blockchain browsers may temporarily not work. However, TOR encryption is very important when Internet providers completely block traffic and switching to this mode, you get complete freedom and no blocks for transactions.

Confidentiality of transactions (the Blockchain transaction)

The wallet can change the model of a standard transaction, mixing inputs and outputs, making it difficult to identify certain cryptocurrencies. In the current update, you can select one of several modes for the transaction privacy level: deterministic lexicographic sorting or shuffle mode.

Mode: Lexicographic indexing

Implemented deterministic lexicographic sorting using hashes of previous transactions and output indexes for sorting transaction input data, as well as values and scriptPubKeys for sorting transaction output data;
We understand that information must remain confidential not only in the interests of consumers but also in higher orders, financial systems must be kept secret to prevent fraud. One way to address these privacy shortcomings is to randomize the order of inputs and outputs.
Lexicographic ordering is a comparison algorithm used to sort two sets based on their Cartesian order within their common superset. Lexicographic order is also often referred to as alphabetical order or dictionary order. The hashes of previous transactions (in reverse byte order) are sorted in ascending order, lexicographically.
In the case of two matching transaction hashes, the corresponding previous output indexes will be compared by their integer value in ascending order. If the previous output indexes match, the input data is considered equal.

Shuffle Mode: mixing (random indexing)

To learn more about how “shuffle mode” works, we will first analyze the mechanisms using the example of a classic transaction. Current balance Of your wallet: 100 TKEY, coins are stored at different addresses:
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
Addresses in the blockchain are identifiers that you use to send cryptocurrency to another person or to receive digital currency.
In a classic transaction, if you need to send, for example, 19 TKEY — 100 TKEY will be sent to the network for “melting” coins, 19 TKEY will be sent to the Recipient, and ~80.9 TKEY will return to the newly generated address for “change” in your wallet.

https://preview.redd.it/x595qwdottx41.png?width=806&format=png&auto=webp&s=d9c2ae5620a3410ed83f7e16c018165c8ab35844
In the blockchain explorer, you will see the transaction amount in the amount of 100 TKEY, where 80.99999679 TKEY is your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee. Thus, in the blockchain search engine, most of your balance is shown in the transaction.

How does the shuffle mode work?

Let’s look at a similar example: you have 100 TKEY on your balance, and you need to send 19 TKEY.
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
You send 19 TKEY, the system analyzes all your addresses and balances on them and selects the most suitable ones for the transaction. To send 19 TKEY, the miners will be given coins with x2. Addresses, for a total of 20 TKEY. Of these, 19 TKEY will be sent to the recipient, and 0.99999679 TKEY will be returned to Your new address as change minus the transaction fee.

https://preview.redd.it/doxmqffqttx41.png?width=1400&format=png&auto=webp&s=5c99ec41363fe50cd651dc0acab05e175416006a
In the blockchain explorer, you will see the transaction amount in the amount of 20 TKEY, where 0.99999679 TKEY is Your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee.
The shuffle mode has a cumulative effect. with each new transaction, delivery Addresses will be created and the selection of debit addresses/s that are most suitable for the transaction will change. Thus, if you store 1,000,000 TKEY in your wallet and want to send 1 TKEY to the recipient, the transaction amount will not display most of your balance but will select 1 or more addresses for the transaction.

Selecting the recovery method for each digital currency (Blockchain restore)

Now you can choose the recovery method for each currency: API + Blockchain or blockchain.
Note: This is not a syncing process, but rather the choice of a recovery method for your wallet. Syncing takes place with the blockchain — regardless of the method you choose.
https://preview.redd.it/gxsssuxrttx41.png?width=1080&format=png&auto=webp&s=cd9fe383618dda0e990e86485652ff95652a8481

What are the differences between recovery methods?

API + Blockchain

In order not to load the entire history of the blockchain, i.e. block and transaction headers, the API helps you quickly get point information about previous transactions. For example, If your transactions are located in block 67325 and block 71775, the API will indicate to the node the necessary points for restoring Your balance, which will speed up the “recovery” process.
As soon as the information is received, communication with the peers takes place and synchronization begins from the control point, then from this moment, all subsequent block loading is carried out through the blockchain. This method allows you to quickly restore Your existing wallet.
‘’+’’ Speed.
‘’-’’ The API server may fail.

Blockchain

This method loads all block headers (block headers + Merkle) starting from the BIP44 checkpoint and manually validates transactions.
‘’+’’ It always works and is decentralized. ‘’-’’ Loading the entire blockchain may take a long time.

Why do I need to switch the recovery method?

If when creating a wallet or restoring it, a notification (!) lights up in red near the selected cryptocurrency, then most likely the API has failed, so go to SettingsSecurity CenterPrivacyBlockchain Restore — switch to Blockchain. Syncing will be successful.

Selecting the address format

You can choose the address format not only for Bitcoin but also for Litecoin. Legacy, SegWit, Native SegWit. Go to SettingsManage WalletsAddress Format.

https://preview.redd.it/nqj0nwutttx41.png?width=1080&format=png&auto=webp&s=fc04b8ee8339ab27d3203ff551013cda7aa9e8db

Working at the code level

Enhanced validation of transactions and blocks in the network

Due to the increased complexity in the Tkeycoin network, we have implemented enhanced validation of the tkeycoin consensus algorithm, and this algorithm is also available for other cryptocurrencies.

What is the advantage of the enhanced validation algorithm for the user

First, the name itself speaks for itself — it increases the security of the network, and second, by implementing the function — we have accelerated the work of the TkeySpace blockchain node, the application consumes even fewer resources than before.
High complexity is converted to 3 bytes, which ensures fast code processing and the least resource consumption on your device.

Synchronization

The synchronization process has been upgraded. Node addresses are added to the local storage, and instant synchronization with nodes occurs when you log in again.

Checking for double-spending

TkeySpace eliminates “double-spending” in blockchains, which is very valuable in the Bitcoin and Litecoin networks.
For example, using another application, you may be sent a fake transaction, and the funds will eventually disappear from the network and your wallet because this feature is almost absent in most applications.
Using TkeySpace — you are 100% sure that your funds are safe and protected from fraudulent transactions in the form of “fake” transactions.

The bloom filter to check for nodes

All nodes are checked through the bloom filter. This allows you to exclude fraudulent nodes that try to connect to the network as real nodes of a particular blockchain.
In practice, this verification is not available in applications, Tkeycoin — decided to follow a new trend and change the stereotypes, so new features such as node verification using the bloom filter and double-spending verification are a kind of innovation in applications that work with cryptocurrencies.

Updating the Binance and Ethereum libraries

Updated Binance and Ethereum libraries for interaction with the TOR network.

Interface

Function — to hide the balance

This function allows you to hide the entire balance from the main screen.

Advanced currency charts and charts without authentication

Detailed market statistics are available, including volumes, both for 1 day and several years. Select the period of interest: 1 day, 7 days, 1 month, 3 months, 6 months, 1 year, 2 years.
In version 1.3.0, you can access charts without authentication. You can monitor the cryptocurrency exchange rate without even logging in to the app. If you have a pin code for logging in, when you open the app, swipe to the left and you will see a list of currencies.

News

In the market data section — in the tkeyspace added a section with current news of the cryptocurrency market.

https://preview.redd.it/lz1e7ynxttx41.png?width=1080&format=png&auto=webp&s=b6f1858d8752cfc6187df5d7b8a2ce25813e2366

Blockchain Explorer for Tkeycoin

Transaction verification for Tkeycoin is now available directly in the app.

Independent Commission entry for Bitcoin

Taking into account the large volume of the Bitcoin network, we have implemented independent Commission entry — you can specify any Commission amount.
For other currencies, smart Commission calculation is enabled based on data from the network. The network independently regulates the most profitable Commission for the sender.

ARPA is available on top exchanges such as Binance, Huobi Global, Gate.io, KuCoin, HitBTC, mxc.com, Coinone, Hanbitco, and many more. Listing on Bithumb will bring better liquidity, trading depth, better access and global awareness for privacy-preserving computation, ARPA project and holders. It is an important milestone for ARPA’s globalization.

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).
Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.
Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.
