Blockchain nodes are nodes that perform various functions in the network. They play an important role in ensuring the security and consistency of distributed ledger data. Nodes are computers on the blockchain that broadcast transactions to other participants for confirmation. Being part of a distributed network, a node is one of the devices that controls it.

Nodes store transaction blocks, which serve as an archive for recovery, and also add new blocks. Changes are reflected in each node of the blockchain, which confirms similar transactions in the network.

Types of blockchain nodes

There are different types of nodes in the blockchain depending on their functions:

Full Nodes

These nodes are fully synchronized with the blockchain and store the entire block history. They verify signatures to confirm transactions and blocks, ensure the reliability and security of the blockchain, and also serve as a backup of all data and restore transactions in cases such as power outages or system failures.

Full nodes constantly exchange information about newly added operations, and to run such a node and process a large amount of data, the user needs a device with sufficient computing power.

Having a full node allows the user to independently check incoming transfers, and if desired, he can also become a participant in the mining of cryptocurrencies.

Lightweight nodes

A lightweight node stores partial blockchain data. In these cases, only the block headers are loaded. Light nodes use Simplified Payment Verification (SPV) to confirm transactions. They have the advantage of being easy to maintain and run, but they require full nodes to access the entire history of the blockchain.

Mining Nodes

These nodes carry out the work of creating new blocks in the blockchain. They are designed to solve the problem of proof of work (Proof-Of-Work consensus algorithm, PoW) and cryptocurrency mining. Unlike full nodes, mining nodes provide rewards for their owners. Mining nodes often use specialized hardware and consume large amounts of energy.

Staking nodes

They are an analogue of mining nodes for blockchains with the Proof of Stake (PoS) consensus algorithm. In this case, the owner is rewarded for holding coins in the account, not for calculations, and powerful equipment is not required to run.

Supernodes, listening nodes

A supernode is a full-fledged node that stores blockchain data and serves as its communication line. Transaction data and additional historical information are transmitted through supernodes. A supernode requires a fast Internet connection and high computing power to operate.

Masternodes

A masternode, like a full node, stores all information from the blockchain and is synchronized with it, but can also ensure the anonymity of transactions by splitting them. To launch a masternode, the user needs to block a certain amount of native blockchain coins as collateral. For its management, the system accrues a portion of the commissions paid to miners. The masternode owner participates in project management.

Authority nodes

Authoritative nodes are chosen by blockchain participants to govern and are vetted to ensure they can fulfill that role. Most blockchain systems use a proof of authority system, and approved nodes have full identity information, unlike anonymous nodes. In some blockchain systems, there are no authoritative nodes.

Archival full nodes

Such nodes operate in archive mode and store all transactions for the block to which they belong. Clients of full nodes use them to quickly access information about smart contracts on the first 200 blocks. Finding blocks on the network requires accurate reference data, so each blockchain address directs the full node user to this data.

Why do you need to run nodes?

A few main reasons to run a node:

• Confirmation of new blocks. Running a node is required to confirm and maintain the integrity of new transaction blocks. A user can run multiple nodes to perform the same function.
• Ensuring control over transactions. Managing a blockchain node gives the user full control over operations, without the participation of third parties.
• Opportunity to participate in blockchain maintenance as a node owner. Some of the maintenance issues are the security and accuracy of online transactions.
• Low startup costs (excluding mining). The requirements for some nodes can be met using a regular PC. Costs can be reduced by operating as a standalone node.

How to start a node

To run a node on the blockchain, you need to download the appropriate software or use cloud services offered by various blockchain platforms. The exact instructions for running a node will depend on the project you choose.

All blockchains have nodes that operate online. Anyone can manage a node with access to the blockchain's transaction history. Most node admins are volunteer crypto enthusiasts.

When starting a node, it is important to take several factors into account:

• Hardware requirements. Running a node may require certain system requirements. The user should study the available documentation of the selected blockchain platform to find out detailed information about the required resources.
• Network bandwidth. Running a node may also require a stable and high-speed Internet connection, especially if the user intends to run full or mining nodes.
• Software installation and configuration. The user will need to download and install the software that is used to run the node. It is important to follow the instructions provided by the developers or the blockchain community to configure the node correctly.
• Safety. When running a node on the blockchain, it is important to ensure the security of your data and funds. The user will be required to create secure passwords, install necessary firewalls, and take other security measures.

How nodes protect the blockchain

• They are open source, providing a consistent experience across the entire blockchain infrastructure. Different node types are differentiated by software privileges and hardware power. The network uses the P2P communication protocol.
• Nodes are interdependent. They depend on each other when adding new blocks and validating transactions. Thus, a block is a collection of network transactions.
• Nodes store the current history of blockchain transactions on a distributed network. Thus, each node stores a copy of operations.
• All users can access data on the blockchain. Node transactions are visible to all users. They store the same history of transactions on the network. The node acts as a distributed backup. When a blockchain network fails, one node can restore a block.

How nodes ensure decentralization of cryptocurrencies

Blockchain operates on a decentralized model. Nodes exchange information and update each other automatically. Inactive nodes receive similar updates as soon as they come online. They have a unique identifier called a hash.

Nodes participate in the management of the blockchain infrastructure without a leadership figure, and also store blocks and transactions in them, which ensures the availability of all data even if one or more nodes fail.

How to make money on nodes

As for making money on nodes, it depends on the specific blockchain. In the case of mining nodes, the user can receive rewards for creating new blocks and processing transactions. In systems with a PoS algorithm, validation nodes can earn money by holding a certain number of blockchain tokens and participating in the transaction approval process.

However, profitability and rewards on nodes may vary depending on various factors such as the consensus algorithm, network complexity and the number of participants. Before launching a node to make money, it is recommended to conduct additional research and become familiar with the rules and features of the chosen platform or blockchain.

 

Why I chose DeltaChat for private communication

• There is no centralized server. Any email server you specify is used

• Secure e2e encryption Autocrypt Level 1 . The implementation has undergone an independent audit

• Open Source , non-commercial, funded by NGOs and users

• Audience ~1M. Cannot be accurately assessed due to lack of telemetry

• Disadvantages: not as fast and there is no (yet) message editing, reactions or threads

But the post office is dead and smells like mothballs

SQL also “died” with the advent of NoSQL, as a result, NoSQL pioneers like Elastic added SQL engines. And SQL is still one of the top skills in the IT labor market.

Same with mail. It is over 30 years old, but many people use it every day, the rest at least when registering in online services. New products and even protocol implementations are appearing .

Mail remains the most successful decentralized federated messaging network. Fediverse and Matrix are still far from email.

What does the popular messenger know about you?

Using Telegram, WhatsApp, Signal as an example:

• Phone number that uniquely identifies you and excludes anonymity;

• IP gives out your geolocation;

• Contacts even for those who do not have a messenger;

• Meta-information - with whom and when do you communicate, what groups are you in;

• The contents of messages are available in Telegram chats without a lock, unlike WhatsApp and Signal;

• As well as reading SMS , calendar , and much more .

Privacy DeltaChat

DeltaChat also has access to private data on the phone, albeit half as much as Signal .

The fundamental difference is that DeltaChat does not use centralized servers . Messages go through the mail server you specify - be it Gmail or your own.

You can verify this by analyzing the traffic using PCAPdroid . You will not find a single connection past your mail server. Thus, DeltaChat is not subject to the risks of data leakage, like the popular instant messengers above. Privacy by Design at its best!

What is DeltaChat exposed to?

Theoretically MITM if uncontrolled mail servers are used. In practice, it’s hard to imagine Gmail interfering with the key exchange process and replacing them to read your correspondence. Just one such confirmed case could kill Google's reputation. Therefore, I would rate the probability as close to zero, although technically possible.

You can counteract MITM by exchanging keys in person or via an independent channel; this is conveniently implemented in delta.

But it is more private to use a personal mail server, because although Gmail will not see the contents of the correspondence, it will know with whom and when you are corresponding.

Which mailer to use

Any with SMTP and IMAP support. Therefore, Tutanota , ProtonMail and Hey will not work. Here you can check your email provider for compatibility.

If you want to be completely private, then welcome to self-hosted. Below are convenient solutions I have tested:

• Mail-in-a-Box , iRedMail - if you know how to use the Linux console;

• mailcow - for Docker lovers;

• SelfPrivacy - if you have no IT skills at all, but want your own mail server (my project);

• Write in the comments how else you can quickly, easily and privately deploy your mail server, please!

Promising features

How to use

Installs on any platform. It 's as difficult to set up as any email client. It can be used as a full-fledged replacement for an email client, then the messages will be unencrypted and the recipient will see a regular letter. The first message sometimes arrives with a delay due to greylisting .

To use one account from different devices, transfer the keys via backup .
If you connect using a regular email client or DeltaChat without keys, you will see encrypted mail. That's how it should be - Privacy by Design! Keys are stored only on the device.

Total

Over two years of use, the project before my eyes has transformed from a successfully tested concept into a full-fledged replacement for popular instant messengers with privacy at maximum speed. About 50% of my chat conversations are on DeltaChat.

For testing, you can write me something nice: kirill.zholnay (doggie) selfprivacy.org

A491598198/Meshrabiya: Virtual mesh network for Android that operates over WiFi

8-10 minutes

---

Meshrabiya

Meshrabiya is a mesh network for Android that operates over WiFi. It allows applications to seamlessly communicate over multiple hops and multiple WiFi direct and/or Local Only Hotspots. Each device is given a "virtual" IP address (typically a random auto-generated address e.g. 169.254.x.y). Applications can then use the provided SocketFactory and/or DatagramSocket class to communicate with other nodes over multiple hops as if they were directly connected. This works with various higher level networking libraries such as OkHttp.

It is intended for use in situations where multiple Android devices need to communicate with each other and a WiFi access point is not available e.g. schools and health clinics without WiFi infrastructure, when hiking, etc. WiFi enables high-speed connections with tests obtaining 300Mbps+. Using multiple hops over multiple WiFi direct groups enables more devices to connect than is possible using a single device hotspot.

Meshrabiya is entirely open-source and does not have any proprietary dependencies (e.g. it works with Android Open Source Project devices and does not use/require Google Play Services, Nearby Connections API, etc).

Meshrabiya provides socket factories (for both TCP and UDP) that can create sockets to route data between nodes over multiple hops as if they were directly connected. The socket factory can also be used with other networking libraries (e.g. OkHttp) to make it easy to send/receive data over the virtual mesh.

How it works:

• Node A creates a hotspot using a Wifi Direct Group. or Local Only Hotspot. It generates a "connect link" that includes the hotspot SSID, passphrase, ipv6 link local address (if a WiFi direct group), BSSID (where possible), and the service port number.
• Node B obtains the connect link by scanning a QR code (this could also potentially be discovered via Bluetooth Low Energy Advertising). Node B connects to the hotspot of Node A using the Wifi Bootstrap API. If Node A created a WiFi direct group, then Node B will use the ipv6 link local address to reach Node A. If Node A created a Local Only Hotspot, then Node B will use the DHCP server address to reach Node A. Node B sends a UDP packet to the known address / service port of Node A to enable Node A to discover Node B. Node A and Node B can now communicate. The connection is done using WifiNetworkSpecifier on Android 10+ and using WifiManager on prior versions. On Android 10+ the user will normally only see
  a confirmation dialog the first time a connection is established between two nodes (except when it is not possible for a single node to maintain the same SSID and/or when the BSSID is unknown).
• Node B creates its own hotspot. Node C (and so forth) can connect. All nodes periodically broadcast originator messages that include their virtual IP address and connect link. The propogation of originator messages is subject to limits on the maximum number of hops. When a node receives an originator message it knows the other node, and it knows the next hop if it wants to send traffic to that node. This is based on the BATMAN Originator Message concept.
• Each node can simultaneously operate both a hotspot for incoming connections and make one outgoing connection via its WiFi station (client). There are two possible ways to do this, each of which has some advantages and disadvantages:
• WiFi Direct Group Almost all Android devices (except it seems Android 11+ devices that support WiFi station - Access Point concurrency) can create a WiFi direct group and simultaneously remain connected to a WiFi access point (as a station). Creating a WiFi direct group creates a hotspot for "legacy devices" that operates a normal hotspot (and does not share Internet). IPv6 link local must be used to avoid an IP conflict due to the fact that Android assigns the IP address 192.168.49.1 to all nodes that operate as a WiFi direct group owner. We also use the link local IPv6 address to attempt to calculate the MAC Address, which needs to be specified to avoid a user prompt each time a user reconnects. Using the link local address to calculate the MAC address avoids the need to use CompanionDeviceManager to discover the Mac address (which requires using an intent result and results in users seeing two dialog boxes on Android 10). It is possible to specify the hotspot SSID, passphrase and band (2.4Ghz or 5Ghz) on any Android 10+ device.
• Local Only Hotspot This is supported on all Android 8 devices, however it can only operate concurrently with being connected to another hotspot if WiFi station - Access Point concurrency is supported. This is only available on Android 11+ devices and requires hardware support. Generally lower-end devices are less likely to have this feature. Android generates a random subnet range so there is no IP address conflict when one device is both operating as a Local Only Hotspot provider and connected to another Local Only Hotspot at the same time. It is only possible to specify the hotspot SSID, passphrase, and band on Android 13+ using a hidden API.

Getting started

Add repository to settings.gradle :

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
      ...
      maven { url "https://devserver3.ustadmobile.com/maven2/" }
    }
}       

Add the dependency

implementation "com.github.UstadMobile.Meshrabiya:lib-meshrabiya:0.1-snapshot"

Connect devices

Create a Virtual Node:

//Create a DataStore instance that Meshrabiya can use to remember networks etc.
val Context.dataStore: DataStore<Preferences> by preferencesDataStore(name = "meshr_settings")

val myNode = AndroidVirtualNode(
    appContext = applicationContext,
    dataStore = applicationContext.dataStore,
    //optionally - set address, network prefix length, etc.
)

Create a hotspot on one node:

myNode.setWifiHotspotEnabled(
  enabled = true,
  preferredBand = ConnectBand.BAND_5GHZ,
)

val connectLink = myNode.state.filter {
   it.connectUri != null
}.first()

Use the connect link to connect from another node:

val connectLink = ... //Get this from QR code scan etc.
val connectConfig = MeshrabiyaConnectLink.parseUri(connectLink).hotspotConfig
if(connectConfig != null) {
  myNode.connectAsStation(connectConfig)
}

Exchange data using TCP

1. On the server side - create a normal server socket:

val serverVirtualAddr: InetAddress = myNode.address 
val serverSocket = ServerSocket(port)

2. On the client side - use the socket factory to create a socket

val socketFactory = myNode.socketFactory
val clientSocket = socketFactory.createSocket(serverVirtualAddr, port)

The Socket Factory uses a "socket chain" under the hood. It will lookup the next hop to reach the given destination. It will then connect to the next hop and write its destination to socket stream, similar to how an http proxy uses the host header. Each node runs a chain socket forwarding server. Once the next hop is the destination (e.g. it reaches a node that has a direct connection to the destination node), then the socket is connected to the destination port. See ChainSocketServer for further details.

The Socket factory will fallback to using the system default socket factory for any destination that is not on the virtual network (e.g where the ip address does not match the netmask of the virtual node). It is therefor possible to use the socket factory anywhere, even when connections to non-virtual destinations are required - e.g. it can be used with an OKHttp Client and the client will be able to connect to both virtual and non-virtual addresses. e.g.

val okHttpClient: OkHttpClient = OkHttpClient.Builder()
            .socketFactory(myNode.socketFactory)
            .build()

Exchange data using UDP

Create a DatagramSocket with a given port (or use 0 to get a random port assignment)

val datagramSocket = myNode.createBoundDatagramSocket(port)

The socket can be used the same as a normal DatagramSocket (e.g. by using send/receive), but it will send/receive ONLY over the virtual network. Broadcast packets are supported by setting the destination address to 255.255.255.255

Wallets for cryptocurrencies TOP-73: a complete list [2024], the best and most reliable crypto wallets

By✍ Serhii Kosenkov 

biznescat.com

View Original

There are several types of cryptocurrency wallets. The main thing is to choose a reliable and safe one. You can use the installation of special software on a computer, phone, create an online crypto wallet on the website.

Any cryptoexchanges will provide the user with a wallet for storing cryptocurrencies after registering an account. There are hardware devices and paper wallets for generating a private key and address, these methods are classified as cold storage.

It is important to understand that cryptocurrency is stored at addresses in the blockchain. And wallets are needed for the convenience of managing private keys and obtaining access to addresses. According to the method of storage, they are divided into cold (without Internet connection) and hot (with Internet connection).

The editors of BiznesCat.com in the article reviewed the list of the best hardware, desktop, online cryptocurrency wallets for storing coins: Bitcoin, Ethereum, ERC20 tokens, Ripple, Bitcoin Cash, Litecoin, Stellar Lumer, Dash, Iota, EOS, Cardano, Neo, Tron, Monero, Vechain, Ethereum Classic, Tether, Qtum, OmiseGo, Binance Coin, as well as multi-cryptocurrency wallets.

Which crypto wallet to choose? It depends on many conditions. The most important thing is security, the ability to save a private key or seed phrase. If you need to store a large amount, it is better to buy a hardware wallet. Those who trade on the exchange can store cryptocurrency on it to avoid paying transfer fees and make transactions quickly. It is more convenient to store ERC-20 standard tokens on the crypto exchange instead of downloading a separate wallet for each type.

Desktop crypto wallets are suitable for everyday use, payment and receiving transfers. Online services are good for those who are just starting to understand cryptocurrency, but storing large amounts in them is not recommended. You can create and try to work with all the proposed options, combining both hot and cold methods.

We remind you that you can buy or exchange cryptocurrency on cryptocurrency exchanges or in exchangers, p2p exchanges.

What are the cryptocurrency wallets?

There are several types of crypto wallets, each of which has different ways of storing keys and providing access to them. The three main categories are software (which in turn are divided into online, desktop and mobile), hardware and paper.

Let's consider all these types in more detail.

1. Desktop (local) wallets are downloaded and installed on a personal computer/laptop. You can only log in to your account from the same device on which they are installed. This provides a certain level of security, but at the same time, it is dangerous in a situation where the computer is infected with a Trojan or a virus.
2. Web wallets (online) work in the cloud and can be accessed through a browser from any device. This is convenient, but private keys are usually stored not with you, but with a third party - a service provider, which exposes them to the risk of attacks by attackers.
3. Mobile cryptocurrency wallets are applications for mobile platforms. They are convenient in that you can perform an emergency operation anywhere at any time. But they have minimal functionality, and are also the least well protected.
4. Hardware crypto wallets store user keys on an external device similar to a flash drive - this is their main difference from software ones. With such devices, you can store cryptocurrency offline, connecting to the Internet only when you need to make a transaction. If you lost your wallet, the person who found it will not be able to use it, as access is protected using a PIN code.
5. Paper wallets for cryptocurrencies guarantee a high level of security and are also quite easy to use. This definition can refer to two concepts: a simple physical copy of the printed public and private keys, as well as the software used to create a pair of keys that are then printed.

Matbi Online Crypto Wallet and Exchanger

The Matbi crypto wallet allows you to store Bitcoin, Litecoin, Dash, Dash. Works since 2014. The online service allows you to buy or sell cryptocurrency. Available payment systems: Qiwi, Yandex, Oschadbank, Alfa-Bank, VTB, Promsvyazbank, Visa/Mastercard and others. In most cases, there is no commission when topping up an account with Fiat. Details in the "Tariffs" section.

To register a wallet, you need to enter a phone number and a password. The official website is matbea.com.

Hardware cryptocurrency wallets

Hardware wallets are considered the most secure for storing cryptocurrencies. Private keys are generated locally and are not transmitted anywhere. Special secure chips are used to protect against hacking and viruses, transactions are confirmed by entering a PIN code, and a mnemonic (seed) is generated to restore access. Well-known manufacturers of hardware wallets are Ledger, Trezor, KeepKey, Cool Wallet, Digital Box. We recommend purchasing any of them, as they provide maximum protection for cryptocurrency assets.

• The most popular device is the Ledger Nano S. The price at the time of writing the review is 59 euros. Delivery is carried out from France within 2 weeks. Visa / Mastercard, Qiwi, PayPal plastic bank cards are accepted for payment; cryptocurrency Bitcoin and Bitcoin Cash. Warranty - 2 years. Official website to order wallet: www.ledger.com.

On January 7, 2019, the company presented a new hardware wallet ledger Nano X. Its price is slightly higher — 119 Euros.

• Another well-known manufacturer is Trezor (website trezor.io). Produces two types of crypto wallets - One and Model T. Delivery time from the Czech Republic is 1-2 weeks. You can buy the device using a bank card or bitcoin. The wallet supports cold storage of 600+ cryptocurrencies.

Local (desktop) wallets for cryptocurrencies

Local wallets are one of the reliable ways to store cryptocurrencies. At the same time, the owner has full control over his crypto-coins, as private keys are generated and stored locally on the device without access to this information by third parties.

You can download a local wallet only from the official website of the developer, so as not to end up on fraudulent phishing sites. Before downloading, you need to choose the version for your operating system (Windows, OS X, Linux) or Mobile application.

There are two types of software wallets for local use:

1. Thick (heavy) — after installation and start-up, download the network blockchain. They take up a lot of space on the computer and require a long time. These include Bitcoin Core, Ethereum Wallet and other official cryptocurrency wallets.
2. Thin (Lightweight) - Fast online synchronization occurs with servers without downloading the blockchain chain. These include Exodus, Electrum, Jaxx and others.

The best local wallet for Exodus cryptocurrencies

Exodus is a multi-currency local wallet for PC. You can store most popular cryptocurrencies: Bitcoin, Ethereum, Bitcoin Cash and Gold, EOS, Ethereum Classic, Litecoin and others.

Supported tokens of the ER20 standard: Binance, Qtum, Revaine, Tron, Vechain, Tent, Storm, Cyber ​​and many others. You can add them as follows: "Setting" — "Assets" or "Wallet" — "Add more". You can download the wallet on the official website — exodus.io/releases.

The wallet has the ability to exchange cryptocurrencies through the "Exchange" section. For this, the ShapeShift service is used.

Private keys are created, stored locally on the computer and are not shared with third parties. To see and export the private key, you need to open the developer panel. This can be done in two ways:

• Press Shift + CTRL + D simultaneously.
• Go to the "Help" section and at the very end from the list of questions select "How do I open the Developer menu" and press the button.

The top menu will open with all possible advanced wallet settings. To export keys, you need to go to "Exodus" — "Developer" — "Assets", select cryptocurrency, click "Export Private Keys" and confirm the "I'm sure" action. The user will see the path to the csv file. It contains data in the following format "ADDRESS, PATH, BALANCE, PRIVKEY". After saving, you need to delete the file.

After replenishing the balance through "Backup" there is an opportunity to set a password, e-mail, and get a 12-word seed phrase. It is better to do the translation with a small amount to activate these security options. To further restore access to the wallet, you need to go to the developer menu, select "Exodus" — "Developer" — "Restore" and decide on a method. "Restore from 12-world phrase" - restoration by Seed-phrase; "Restore from recovery link" - using a password, email and a link in the letter.

To receive or transfer cryptocurrency, you need to go to "Wallet", select a cryptocurrency and click "Receive". A public address will appear on the screen in the form of a QR code and an alphanumeric set of characters. "Send" - transfer of cryptocurrencies to another address. The status of each cryptocurrency can be tracked at the link: www.exodus.io/status.

Advantages of the wallet:

• Attractive design, portfolio, change of design themes.
• Full control over private keys.
• Ability to store most popular cryptocurrencies and ERC 20 tokens.
• Backup and restore using seed or email + password + link.
• No top-up fee. A network fee is charged for the transfer to the nearest block. The service does not charge additional fees.

Disadvantages:

• No two-factor authentication.
• Closed source, although some components are open source.

Best Bitcoin (BTC) Cryptocurrency Wallets

The largest number of wallets have been created for Bitcoin cryptocurrency. This is not surprising, as it is the first and most popular virtual coin.

Wallets for storing bitcoin are different:

• Local (desktop) for installation on a PC, phone, tablet.
• Online services.
• Cryptocurrency exchanges.
• hardware
• Paper.

All of them have different degrees of protection, purpose and functionality.

Wallets installed on a computer are divided into "heavy" or "thick", they require the download of the entire blockchain chain for their operation. This is the most secure way to store cryptocurrency. For the Bitcoin network, the blockchain size is 150 GB. To "difficult" wallets include the official Bitcoin Core cryptocurrency wallet. "Easy" ("thin") do not require a blockchain download to work, and synchronization occurs with online servers. Local wallets have the ability to import, export private keys and restore access using a seed phrase.

There is no need to install software or download blockchain to create online or web wallets. The user will only need to register on the site, write down passwords, and configure the necessary account security parameters. It is not recommended to keep large amounts for a long time. In some wallets, there is an option to extract the private key.

A cryptocurrency exchange wallet is one of the easiest options. You can buy, sell cryptocurrency and store it on the exchange site. Access to private keys is not provided.

A hardware wallet is considered the most reliable way to store cryptocurrency. It is made in the form of a flash drive and allows you to store not only bitcoins, but also other coins. The most popular manufacturing companies: Ledger and Trezor. Such devices are paid, for example, Ledger NanoS can be purchased for $79.

Paper wallets belong to cold storage. They generate a public bitcoin address, a private key in the form of a QR code and a set of numbers and letters. A private key (Private Key, Secret) is created on a personal device, third parties cannot find it. You can create such a wallet on the bitaddress.org website.

Any wallet stores a private key and a public address.

For long-term storage, it is safest to use "cold storage", in which the private key is stored without access to the Internet. To do this, you can write down the private key on a piece of paper or a flash drive and put it in a safe, secure place. To carry out transactions with cryptocurrencies, you just need to import the private key into a wallet that supports this function (Electrum, Bitcoin Core, and others). For example, a user installed an Electrum wallet, transferred bitcoins to it. The plan is to keep them for a few years and then sell them. In its functions, it exports the private key for the address where the cryptocurrency is located and stores it.

What is a private key, wallet address and seed

Cryptocurrency wallet address is public information that other people or Services need to send you money. It is also called a public key.

A private (private) key is, on the contrary, a completely secret code that only you should have access to, it allows you to manage funds. One of the ways to encrypt a private key is a seed phrase. It is 12 English words that are much easier to remember than a 64-digit set of letters and numbers. A seed phrase is also classified information. With its help, you can restore access to the wallet if it is lost.

The function of the private key consists not only in authentication, but also in signing transactions in order to record its belonging to a specific sender. When registering any crypto-wallet, a private key is first created. And already on its basis, public addresses are formed, of which there can be an unlimited number. Reverse decryption is impossible (it is not possible to find out the private key from the public key).

How to choose the best and reliable wallet for storing cryptocurrency

Situations in which a "hot" software-type crypto wallet is suitable:

• You don't keep large sums of money.
• It is important for you that the wallet is free.
• Privacy is not important.
• Interested in the most convenient storage option.

But here are the situations in which it is better to stop at the paper or hardware version:

• The main priority is safety. For example, if you plan to store a large amount of cryptocurrency for a long time.
• No need to make frequent transactions.
• You do not trust a third party and want to control the private key yourself.
