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 AndroidXA 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.
New section: Privacy
TORStarting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies.
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.
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 indexingImplemented 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.
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.
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 + BlockchainIn 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.
‘’-’’ The API server may fail.
BlockchainThis 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 Settings — Security Center — Privacy — Blockchain Restore — switch to Blockchain. Syncing will be successful.
Selecting the address formatYou can choose the address format not only for Bitcoin but also for Litecoin. Legacy, SegWit, Native SegWit. Go to Settings — Manage Wallets — Address Format.
Working at the code level
Enhanced validation of transactions and blocks in the networkDue 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 userFirst, 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.
SynchronizationThe 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-spendingTkeySpace 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 nodesAll 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 librariesUpdated Binance and Ethereum libraries for interaction with the TOR network.
Function — to hide the balanceThis function allows you to hide the entire balance from the main screen.
Advanced currency charts and charts without authenticationDetailed 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.
NewsIn the market data section — in the tkeyspace added a section with current news of the cryptocurrency market.
Blockchain Explorer for TkeycoinTransaction verification for Tkeycoin is now available directly in the app.
Independent Commission entry for BitcoinTaking 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.
New digital currenciesThe TkeySpace wallet supports +59 cryptocurrencies and tokens.

How do I update TkeySpace to version 1.3.0?
submitted by tkeycoin to Tkeycoin_Official [link] [comments]
Continuing the trend of practicality characteristic of the XXI century, paper money is gradually disappearing from our lives, giving way to more practical digital storage. However, the digitized banking that we now use every day is still far from perfect. For starters, it is completely controlled by third parties. No one owns the numbers they see on the screen — control is entirely owned by third parties, such as banks.
Banks create money out of thin air, and credit is a prime example of this. Money is no longer printed when someone takes out an overdraft or mortgage-it is simply created out of nothing. Moreover, these banks charge disproportionately high fees for the services they provide, and these services are outdated and impractical today.
For example, it is impractical to pay a Commission to spend your money abroad, as it is impractical to wait a few days to verify the transfer of a small amount from You to your relative. All this makes no sense in the interconnected and instantaneous world in which We live today.
Thus, the monetary system has ceased to be practical, it is replaced by a higher form of value storage. In this particular case, it is replaced by a faster and safer system that eliminates expensive operations and gives control to the person.
Money that you have in your Bank account can be considered a virtual currency since it does not have a physical form and exists only in the Bank book. If they lose the book, your money will simply disappear. These are just numbers that you see on the screen. The numbers are stored on the hard drives of Bank servers.
Do you open a regular app and think you have money? They are just bytes of the computer system. Today’s global payment infrastructure moves money from one payment system to another through a series of internal Deposit transfers between financial institutions. Since these transfers occur in different systems with a low level of coordination, the calculation of funds is slow, often 3–5 days, capturing liquidity.
How do payments work?When you make a money transfer, for example, from your Bank card to the Bank card of a friend or acquaintance, you see an instant transfer, so to speak, moving numbers from you to the Recipient. For the user, the transfer is carried out instantly, and the exchange of obligations between the participants of the process takes place within 3–7 days, the User does not know about it and hardly ever thinks about it.
When you make a payment at a supermarket or any other point of sale, at the time of payment, information from the POS-terminal is sent to the acquiring Bank — then the acquiring Bank sends a request that passes through the payment system (Visa or MasterCard) and then transmitted to Your Bank, which confirms the operation. At this point, there is no write-off of funds. The funds are temporarily held, and the actual withdrawal will take place within a few days, the maximum processing time is up to 30 days.
Currency transactions and payments abroadYou may have noticed that after making a transaction in a different currency, such as yen or dirhams, or any other currency that differs from the currency of your account or buying an item abroad, the amount charged may differ from the amount that was reflected immediately after payment.
Why is this happening?As soon As you have made a transaction with Your Bank card — the local Bank transfers the information to the payment system: Visa or MasterCard — the payment system converts the currency used into the billing currency.
Billing currency — the currency that will be used for payment with the payment system by your Bank that issued the card. For the US, the billing currency is the dollar, in Europe — the Euro.The billing currency may also differ depending on the issuing Bank — the Bank that issued your debit card. For example, some banks use the billing currency — Euro when making payments with MasterCard cards in the United States, which will lead to additional costs when converting euros into dollars.
If the payment is in other currencies, the payment scheme will become more complicated and, accordingly, its cost will be more expensive. The transfer rate from one settlement currency to another is set by the payment system: Visa and MasterCard.
If the currency of your Bankcard is the same as the currency of the payment system, the payment will take place without additional operations. For example, You have a dollar card, you make a payment in dollars in the United States, and if you make a payment with a dollar card in Europe, your Bank will convert the amount at its exchange rate, which will lead to additional costs. There are exceptions, some European banks can use dollars for settlements, but this is more an exception than a rule.
Also, if, for example, you pay for purchases in China using a Bank card in euros, then double conversion is inevitable.
Thus, payment in dollars is universal all over the world, except for the European Union countries. The dollar is a global currency and is therefore often used for binding in international settlements.
Now we understand that due to differences in the account currency and the differences in the VISA or MasterCard payment system, additional conversions may occur, which will lead to additional bank fees. as a result, the actual payment amount will differ from the amount debited from your card.
In addition to paying for conversion in the payment system and paying for currency conversion in your Bank, some banks charge an additional fee for conducting a cross-border transaction.
Where do we lose money when making debit card payments?
Сryptocurrency exchangesAnd now back to the numbers on the screen, this topic affects not only banks but also centralized cryptocurrency exchanges:
There are many services, both online and apps, that are centralized, regardless of what they will be called: Bitcoin wallet or bitcoin exchange. This means that when you add funds to an account in such a wallet, the funds are stored on the developecompany’s side. In simple words, all your funds are stored in the wallets of the system’s creators.
If you use a centralized app, you have a risk of losing funds. Although the application is called cryptocurrency, it does not affect its main principles — it is decentralization.
In other words, using systems where there is a Central authority, especially in the cryptocurrency market — the risk increases, so we recommend using decentralized systems for storing currency to reduce risks to a minimum.
Decentralization is the process of redistributing, dispersing functions, forces, power, people, or things from a Central location or governing body. Centralization is a condition in which the right to make the most important decisions remains with the highest levels of management.
Peer-to-peer payment systemsThe opposite and standard of security and independence are peer-to-peer payment systems. Using the application-level network Protocol, clients running on multiple computers connect to form a peer-to-peer network.
There are no dedicated servers in such a network, and each node is both a client and performs server functions. In contrast to the client-server architecture, this organization allows you to maintain the network operability with any number and any combination of available nodes. All nodes are members of the network.
Tkeycoin is a decentralized peer-to-peer payment system based on p2p principles and the concept of electronic cash. P2P technology is a fairer means of mutual settlements between users and companies around the world. Modern payment systems are imperfect and may depend on the will of high-ranking officials.
The main goal of Tkeycoin is to create universal products that will make financial transactions more accessible, profitable and secure.
What do decentralized systems protect against?Using decentralized tools, for example, a local Tkeycoin wallet or a Multi-currency blockchain tkeyspace wallet — Your funds belong only to You and only You can use them, which eliminates the risks of third-party bankruptcy, and such a decentralized architecture can also protect against natural disasters. Given that there is no central server that can be damaged in a natural disaster, the system can work even if there are 2 nodes.
In addition to force majeure situations, you protect your funds from theft and any sanctions from third parties-in our time, this is very important. The owner of Tkeycoin does not need Bank branches, does not need additional verifications, and does not need permission to use, transfer, or even transport Tkeycoin. You can easily carry $1 million worth of Tkeycoin in your pocket and even in theory not know any troubles.
Besides, it is extremely convenient and safe to store even multibillion-dollar capital in Tkeycoin. Imagine that you have a lot, a lot of money, and you need a safe place to store it. Where do you apply? Of course, the Swiss Bank, Yes, but it can easily freeze your accounts and you can easily lose your savings. In recent years, many banks are actively fighting against gray non-cash funds (including offshore ones), and every month more and more legal proceedings are organized on this basis.
The fact is that serious money, for the most part, has a gray tinge, and only a tiny fraction of billions and millions are clean for the law. That is why their owners are often called to court, subjected to pressure, forced to leave the country, and so on. If your money is stored in Tkeycoin, you will not be subjected to such pressure and will avoid the lion’s share of troubles that usually accompany accounts with many zeros.
Using peer-to-peer systems — you will not be called by a Bank Manager and require documents or a fraudster who asks for Your card number and SMS for confirmation. This is simply not the case, wallets are encrypted, and using different addresses guarantees privacy.
As for fees for transfers, there are no Visa or Mastercard payment systems, as well as additional fees that we discussed above.
How are payments made in the Tkeycoin peer-to-peer payment system?
As soon as you sign a transaction, it is sent to the blockchain and the miners are engaged in its confirmation, for which they take a symbolic Commission. Let’s look at an example, the key rate is $1, the transfer fee will be 0.00001970 TKEY or 0.00000174 TKEY.
0.00001970 TKEY=$0.00001970 0.00000174 TKEY=$0.00000174Accordingly, commissions are almost zero. In Europe, on average, you will pay $15–20 for a small Bank transfer.
For example, now sending 1 million dollars to BTC, You will pay a Commission in the area of ≈3–8 dollars. Just think, 1 million dollars, without restrictions, risks, and sanctions, and most importantly, the transaction will be the available day today, and you paid an average of ≈5 dollars for the transfer.
Transactions in the Tkeycoin blockchainNow let’s touch on the topic of how a transaction in the blockchain goes. Once you have sent a transaction, it will be available to the Recipient. The transaction takes place instantly and the User sees not” numbers on the screen”, but real funds-cryptocurrency. This is very convenient when you make any transactions and the Recipient needs to make sure that the payment came.
In the full node-there is a choice of confirmation blocks — this is the amount after which you can use the received cryptocurrency. When sending, you can select the number of confirmations:
• 2 blocks≈10 minutes • 4 block≈40 minutes • 6 blocks≈60 minutes • 12 blocks≈120 minutes • 24 blocks≈4 hours • 48 blocks≈8 hours • 144 blocks≈24 hours • 504 blocks≈3 days • 1008 blocks≈7 daysAs we can see, you can also set a weekly confirmation if necessary. The minimum recommended number is 3 blocks. by default, the full node (local wallet) has 6 blocks installed. The presence of this number of confirmations ensures that Your block will not be forged and will be accepted by the network.
Each new transaction that receives network approval is sent to mempool, where it waits for miners to confirm it. When a miner takes a transaction to include it in the next block, it automatically receives the first confirmation.
Generating blocks in the TKEY networkA block in the TKEY network is generated within 6–10 minutes. the network automatically corrects the complexity and time of block formation. Thousands of transactions or a single transaction can be placed in a block.
Transactions work faster in the TKEYSPACE app because we have already enabled new algorithms and this is now the fastest and most convenient way to exchange various digital currencies.
Anyway, using the full node is also one of the safest ways to store and send Tkeycoin cryptocurrency, and most importantly, the full node stores a full copy of the entire blockchain, which benefits the network and provides protection from information forgery.
The more popular the project becomes, the more load is placed on the network itself. For example, 10,000 transactions passed in one block that was processed quickly, while the other 10–20 transactions in another block hung for a longer time, so temporary “pits” may appear. To deal with them, we are working on implementing additional chains-separate chains that are created for cross-transactions, which ensures fast payments under heavy load.
For the global system — we get a shipment around the world in 6–10 minutes, in cross-chains in 10 seconds. In comparison with the global payment system, which processes cross — border payments within 3–5 days, this is a huge advantage. If we add liquidity to this, we will get a perfect payment system.
Also, you should not forget that if you did not sync with the network and sent a transaction, the transaction may hang in its memory pool and you will have to perform several actions to solve this situation. Here we must understand that syncing with the network is an important point because if you have a connection failure in the Internet Bank, the payment will also not be processed. After all, it will not be sent to a specialist for confirmation.
If you are currently experiencing any delays with transactions, this is due to the transition of CPU mining to GPU, as soon as miners switch to new mining methods, the confirmation of blocks will be consistently fast.
In conclusion: blockchain is a new technology and many terms, concepts and how it all works are still difficult for many to understand and this is normal from innovation.
In many countries, the word cryptocurrency and blockchain are synonymous and no one wants to understand the reality, most people believe that if the blockchain, it means it is related to trading on the cryptocurrency exchange. No one thinks about the real usefulness of certain solutions that will become commonplace for Us in the future.
For example, the Internet banking system dates back to the ’80s of the last century, when the Home Banking system was created in the United States. This system allowed depositors to check their accounts by connecting to the Bank’s computer via their phone. In the future, as the Internet and Internet technologies develop, banks are beginning to introduce systems that allow depositors to get information about their accounts via the Internet. For the first time, the service of transferring funds from accounts was introduced in 1994 in the United States by the Stanford Federal Credit Union, and in 1995 the first virtual Bank was created — Security First Network Bank. But, to the disappointment of the founders of the project, it failed because of strong distrust from potential customers, who, at that time, did not trust such an innovation.
Only in 2001, Bank of America became the first among all banks that provide e-banking services, the whole user base for this service exceeded 2 million customers. At that time, this figure was about 20 % of all Bank customers. And in October of the same year, 2001, and the same Bank of America took the bar in 3 million money transfers made using online banking services for a total amount of more than 1 billion US dollars. Currently, in Western Europe and America, more than 50% of the entire adult population uses e-banking services, and this figure reaches 90% among adult Internet users.
Life changes, and in the bustle of everyday work — we do not even notice how quickly all processes change.
We are experiencing a technological revolution that is inevitable.

Someone says that the blockchain in the phone is marketing. This is possible for most applications, but not for Tkeycoin. Today we will talk about how the blockchain works in the TkeySpace app.
Who else is not in the topic, TkeySpace is a financial application for decentralized and efficient management of various cryptocurrencies, based on a distributed architecture without using a client-server.
In simple words, it is a blockchain in the user’s mobile device that excludes hacking and hacker attacks, and all data is encrypted using modern cryptographic methods.
BlockchainLet’s start with the most important thing — the blockchain works on the principles of P2P networks, when there is no central server and each device is both a server and a client, such an organization allows you to maintain the network performance with any number and any combination of available nodes.
For example, there are 12 machines in the network, and anyone can contact anyone. As a client (resource consumer), each of these machines can send requests for the provision of some resources to other machines within this network and receive them. As a server, each machine must process requests from other machines in the network, send what was requested, and perform some auxiliary and administrative functions.
With traditional client-server systems, we can get a completely disabled social network, messenger, or another service, given that we rely on a centralized infrastructure — we have a very specific number of points of failure. If the main data center is damaged due to an earthquake or any other event, access to information will be slowed down or completely disabled.
With a P2P solution, the failure of one network member does not affect the network operation in any way. P2P networks can easily switch to offline mode when the channel is broken — in which it will exist completely independently and without any interaction.
Instead of storing information in a single central point, as traditional recording methods do, multiple copies of the same data are stored in different locations and on different devices on the network, such as computers or mobile devices.
This means that even if one storage point is damaged or lost, multiple copies remain secure in other locations. Similarly, if one part of the information is changed without the consent of the rightful owners, there are many other copies where the information is correct, which makes the false record invalid.
The information recorded in the blockchain can take any form, whether it is a transfer of money, ownership, transaction, someone’s identity, an agreement between two parties, or even how much electricity a light bulb used.
However, this requires confirmation from multiple devices, such as nodes in the network. Once an agreement, otherwise known as consensus, is reached between these devices to store something on the blockchain — it can’t be challenged, deleted, or changed.
The technology also allows you to perform a truly huge amount of computing in a relatively short time, which even on supercomputers would require, depending on the complexity of the task, many years or even centuries of work. This performance is achieved because a certain global task is divided into a large number of blocks, which are simultaneously performed by hundreds of thousands of devices participating in the project.
P2P messaging and syncing in TkeySpaceTkeySpace is a node of the TKEY network and other supported networks. when you launch the app, your mobile node connects to an extensive network of supported blockchains, syncs with full nodes to validate transactions and incoming information between nodes, so the nodes organize a graph of connections between them.
You can always check the node information in the TkeySpace app in the ⚙ Settings — Contact and peer info — App Status;
TkeySpace creates initiating connections to servers registered in the blockchain Protocol as the main ones, from these servers it gets the addresses of nodes to which it can join, in turn, the nodes to which the connection occurred share information about other nodes.
TkeySpace sends network messages to nodes from supported blockchains in the app to get up-to-date data from the network.
The Protocol uses data structures for communication between nodes, such as block propagation over the network, so before network messages are read, nodes check the “magic number”, check the first bytes, and determine the type of data structure. In the blockchain, the “magic number” is the network ID used to filter messages and block traffic from other p2p networks.
Magic numbers are used in computer science, both for files and protocols. They identify the type of file/data structure. A program that receives such a file/data structure can check the magic number and immediately find out the intended type of this file/data structure.The first message that your node sends is called a Version Message. In response, the node waits for a Verack message to establish a connection between other peers. The exchange of such messages is called a “handshake”.
After the “handshake” is set, TkeySpace will start connecting to other nodes in the network to determine the last block at the end of the required blockchain. At this point — nodes request information about blocks they know using GetBlock messages — in response, your node receives an inv (Inventory Message) from another node with the information that it has the information that was requested by the TkeySpace node.
In response to the received message, inv — TkeySpace sends a GetData message containing a list of blocks starting immediately after the last known hash.
Loading and storing blocksAfter exchanging messages, the block information is loaded and transactions are uploaded to your node. To avoid storing tons of information and optimize hard disk space and data processing speed, we use RDBMS — PostgreSQL in full nodes (local computer wallet).
In the TkeySpace mobile app, we use SQLite, and validation takes place by uploading block headers through the Merkle Tree, using the bloom filter — this allows you to optimize the storage of your mobile device as much as possible.
The block header includes its hash, the hash of the previous block, transaction hashes, and additional service information.
Block headers in the Tkeycoin network=84 bytes due to the extension of parameters to support nChains, which will soon be launched in “combat” mode. The titles of the Bitcoin block, Dash, Litecoin=80 bytes.
And so, let’s continue — application nodes receive information from the blockchain by uploading block headers, all data is synchronized using the Merkle Tree, or rather your node receives and validates information from the Merkle root.
The hash tree was developed in 1979 by Ralph Merkle and named in his honor. The structure of the system has received this name also because it resembles a tree.The Merkle tree is a complete binary tree with leaf vertexes containing hashes from data blocks, and inner vertexes containing hashes from adding values in child vertexes. The root node of the tree contains a hash from the entire data set, meaning the hash tree is a unidirectional hash function. The Merkle tree is used for the efficient storage of transactions in the cryptocurrency blockchain. It allows you to get a “fingerprint” of all transactions in the block, as well as effectively verify transactions.
Hash trees have an advantage over hash chains or hash functions. When using hash trees, it is much less expensive to prove that a certain block of data belongs to a set. Since different blocks are often independent data, such as transactions or parts of files, we are interested in being able to check only one block without recalculating the hashes for the other nodes in the tree.
The Merkle Tree scheme allows you to check whether the hash value of a particular transaction is included in Merkle Root, without having all the other transactions in the block. So by having the transaction, block header, and Merkle Branch for that transaction requested from the full node, the digital wallet can make sure that the transaction was confirmed in a specific block.
The Merkle tree, which is used to prove that a transaction is included in a block, is also very well scaled. Because each new “layer” added to the tree doubles the total number of “leaves” it can represent. You don’t need a deep tree to compactly prove transaction inclusion, even among blocks with millions of transactions.
Statistical constants and nChainsTo support the Tkeycoin cryptocurrency, the TkeySpace application uses additional statistical constants to prevent serialization of Merkle tree hashes, which provides an additional layer of security.
Also, for Tkeycoin, support for multi-chains (nChains) is already included in the TkeySpace app, which will allow you to use the app in the future with most of the features of the TKEY Protocol, including instant transactions.
The Bloom FilterAn additional level of privacy is provided by the bloom filter — which is a probabilistic data structure that allows you to check whether an element belongs to a set.
The bloom filter looks for whether a particular transaction is linked to Alice, not whether Alice has a specific cryptocurrency. In this way, transactions and received IDs are analyzed through a bloom filter. When “Alice wants to know about transaction X”, an ID is requested for transaction X, which is compared with the filled segments in her bloom filter. If “Yes” is received, the node can get the information and verify the transaction.
HD supportThe multi-currency wallet TkeySpace is based on HD (or hierarchical determinism), a privacy-oriented method for generating and managing addresses. Each wallet address is generated from an xPub wallet (or extended public key). The app is completely anonymous — and individual address is generated for each transaction to accept a particular cryptocurrency. Even for low-level programming, using the same address is negative for the system, not to mention your privacy. We recommend that you always use a new address for transactions to ensure the necessary level of privacy and security.
The EXT_PUBLIC_KEY and EXT_SECRET_KEY values for DASH, Bitcoin, and Litecoin are completely identical. Tkeycoin uses its values, as well as other methods for storing transactions and blocks (RDBMS), and of course — nChains.
Secret keyWallets in the blockchain have public and private keys.
Centralized applications usually store users’ private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
A private key is a special combination of characters that provides access to cryptocurrencies stored on the account. Only a person who knows the key can move and spend digital assets.TkeySpace — stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. A backup keyword provides the maximum level of security.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If a phrase consists of 12 words, then the number of possible combinations is 204⁸¹² or 21¹³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in strict order, as it was presented after generation.
ResultNow we understand that your application TkeySpace is a node of the blockchain that communicates with other nodes using p2p messages, stores block headers and validate information using the Merkle Tree, verifies transactions, filters information using the bloom filter, and operates completely in a decentralized model. The application code contains all the necessary blockchain settings for communicating with the network, the so-called chain parameters.
TkeySpace is a new generation mobile app. A completely new level of security, easy user-friendly interfaces and all the necessary features that are required to work with cryptocurrency.
