Electrum



Electrum is one of the earliest Bitcoin wallets, having been introduced near the end of 2011. It is a lightweight, no frills wallet that’s designed to be easy to use while also maintaining a high level of security.

  1. Electrum will generate a seed phrase for your wallet. Please save these 12 words on paper (order is important). This seed will allow you to recover your wallet in case of computer failure. Electrum warns us to never disclose your seed, never type it on a website, and do not store it electronically. In case you save your seed phrase, press.
  2. Makers of the world's first LED Smart Saber™, & Built for Combat. Your destiny awaits.
  3. Electrum is an application marketed by Electrum Technologies GmbH. Sometimes, computer users choose to uninstall this program. This can be efortful because doing this by hand requires some know-how related to removing Windows programs manually.

This Electrum review is going to show you all the security and anonymity features that benefit the users of this wallet. It is considered one of the oldest and most secure wallets when it comes to storing Bitcoin. At the end of the article, you’re going to find a full Electrum guide to lead you step by step through the installation of the wallet and how to use it.

01.Electrum Features & Fees

Let me start with the basics – Electrum is a single coin wallet, supporting only Bitcoin. It’s one of the most preferred platforms to send and receive BTCs, because of the fast and easy setup process. It’s considered an anonymous wallet with privacy features, which makes it a tasty bite for users. Its HD characteristic allows people to easy backup and restore their wallet, thanks to the generating seed.

As a light node, Electrum is requesting information from full nodes. Here I observe the SPV (Simple payment verification) confirmation. This one verifies that your transactions are added in the blockchain.

If I have to be honest, when I initially installed Electrum, it was a bit hard for me to work with the interface. It might not be the most user-friendly on the market but once you get used to it, you’ll forget the struggles in the beginning. I would like to sum now everything I’m planning to show you with the following sections, so you can have an exact idea how am I going to proceed:

Pros & Cons

I would like to clear the air from the very beginning, providing you the advantages and disadvantages of the Electrum wallet. This will help you create an impression and sift the important information. Check the table below and make an informed decision:

Operating System Compatibility

As explained earlier, Electrum is supporting only the BTC coin, so basically there isn’t much to say about the coin support. I would like to talk you about the operating systems. It’s supporting all the Desktop editions – Windows, Linux and Mac. You simply download and set up the Electrum desktop wallet on your personal PC. Another thing to mention here is that there’s also an Android mobile app, which you can download from your app store and install on your smartphone without any minimum requirements. In a word, all the OS, supporting the python3 coding language are compatible with Electrum. Anyway, I’ll commit my resume on the most popular ones:

  • Windows

    Windows 7 or higher

  • Linux

    Ubuntu 16.04 or higher

  • Mac OS

    X 10.11 or higher

  • Android

    Android 5 or higher

Is Electrum Safe?

Security

One of the most wanted factors, when choosing a wallet is the protection level it offers. So, for those of you wondering if Electrum is safe enough, I would like to remind you that it’s a desktop wallet, which means it’s a hot one. Ultimately, it’s connected to the Internet all the time when running, which makes it vulnerable when speaking of hacking attempts. Well, if you upgrade frequently the software, you’ll be able to profit the latest security features. How does it work? You should manually download and reinstall the wallet from the official webpage.

I would like to say a few words on the private key control. It’s you and only you in charge of your private keys. You can and have to keep your private credentials safe to avoid any attacks. You can also export it any time you wish to. Let me give now some additional details on the particular Electrum security features:

Open Source

Тhis means that anyone is able to read and edit the Electrum code. In fact, lots of providers are using this wallet’s core to build other wallets. 

Encryption

Here you’re able to create a password to keep safe your bitcoins from cyber-attacks.

Two-Factor Authentication

You’re able to profit an additional security layer, which provides you the opportunity to secure your wallet by requesting some extra information to sign up, such as the powered by Trustedcoin multisignature. Here you have 2 of 3 keys and Trustedcoin have the other 1. Trustedcoin service is signing the transaction on your behalf acts as a second factor.

Multisignature

This feature provides you the opportunity to work in collaboration, since it requires several people to sign a transaction to get broadcasted in the network.

Privacy and Anonymity

I want to add a few words on privacy, because sometimes it happens to be the most important factor for some users to choose their wallet. If you would like to stay anonymous when performing transactions and you don’t like the idea that everybody can surveil your transactions, there’s something you might use in Electrum.

Hierarchical Deterministic (HD)

This means that Electrum doesn’t reuse the same address for every transaction. Actually, each time you want to receive bitcoins, it can generate for you a new public address to secure your signature.

Virtual Private Network (VPN)

It means that it’s encrypting your traffic, using multiple servers, which makes it hard to track your transaction history.

Tor Network

Using his feature gives you the opportunity to perform anonymous and free of surveillance internet operations.

Transaction Fees

With Electrum, the software sets transaction fees automatically, but you can still change them depending on the urgency of your transactions or in other words, how fast you need them to go through. When you want to send coins using that wallet, use the slider for adjusting the fee. This software option shows you roughly after how many blocks your transaction will go through. The fees you need to pay are estimated according to the ones used in the last blocks.

The tricky part about manually adjusting the fees in your wallet is connected to the time each transaction will be processed by the miners. In case the fee you put is too small, there is a chance your transaction never to go through. Well, don’t worry, if it doesn’t pass you will receive the coins back. However, it may take days and even weeks, so it’s advisable not to temper with the fees too much. Nonetheless, Electrum charges fees for sending BTC. Usually you need to pay 0.2 mBTC. This rate varies, and you can end up paying 0.1 mBTC or lower.

Conclusion

The easy and not time-consuming setup process makes Electrum one of the most used and secure wallets for managing Bitcoin. This high anonymity wallet with top-notch privacy features is taking the tool to a must-have level. Furthermore, the HD characteristic gives you the alternative to easily backup and restore with the help just of a seed phrase. The positive approach doesn’t end here, being a light node means no extra hard disk space and simple verification of your payments.

Well, let’s be honest, every wallet has its downs as well. For starters, Electrum is supporting only Bitcoin, a.k.a. is a single coin wallet. For some of you, that might not be a downside, but for the others, a nice alternative is Exodus together with Jaxx, as multi-coin wallets. Compared to them and even to another single coin wallet Bitcoin Core, Electrum’s interface is a bit complexed and difficult to comprehend. Don’t worry, once figured it will make you forget all the hurdles at the start.

02.Electrum Wallet Guide: How to Setup and Use

In this section, you will get familiar with the detailed guide on how to use Electrum. The key aspects will be pointed out in separate sections – e.g. key elements design, download and software installation. There is also information on how to check your wallet address, send, receive assets, back up or restore keys. This part is ending with some information for the advanced users, going through this wallet`s specifics and sharing some tips on the whole process. You will start off by understanding how to setup Electrum as that is the first step that you need to take.

How to Install

The official Electrum page gives you options, depending on the OS. Choose the one, matching yours. When this is done, just follow the steps below: they include configuration and everything else.

Choose Operating System

  • Download the set up executable package to your PC
  • Double click it and follow the installation wizard
  •  Download the setup archive package to your PC
  • Unzip it at any directory
  • Double click the program’s icon or run it in the terminal.
  • Download the package and run it on your system
  •  Find the file in the list of apps and start it from there

Create an Address

After you’re ready with the installation process and start the wallet for the first time you will be presented with several choices regarding the new address you’re about to make. Here is the setup process in steps:

Create a wallet by naming it
Choose a wallet type

Electrum

Earlier in the article, 2FA and Multi-Signature wallets were mentioned so if you are interested in using any of those features, now is the time to choose between them. From the menu with options, “Standard Wallet” is the basic version and the last option is to import a previously used address or private key.

Create/Import Seed

In case you have previously created a wallet, you should have a Seed phrase. Same goes for having a master key or a hardware device. If this is your first wallet go with the “Create a new seed” option:

Standard or Segwit

The last option from the wizard is the Standard or Segwit Address. If you are not familiar with what Segwit is, we recommend you read it here (link to another site where we have it explained)

Your Seed

Here you see 12 words which represent your seed. Write them down on a save place (piece of paper or a very secure text file) because this is your only way to access the wallet in case of a lost password or the whole device. Now, click Next and write the phrase in the loaded window again, in order to double check that you have written them correctly.

Set a password

The last thing you need to do is to choose a password for your wallet which will be used every time you open the wallet. It’s a good security feature which makes sure your wallet is safe even if you lose the device, you’re using the wallet on.

Wasn’t so hard, right? You have now completed the setting up phase. Finalize it by creating a strong password, which the program will require when you create new wallet to protect your keys. When all that is done, just proceed exploring all that the wallet provides.

Interface Overview

The interface is fairly plain and simple. You have 3 menus – History, Send and Receive. Nothing flashy or distracting. Straight to the point. In the bottom right corner, you can see 4 icons: A lock which lets you change your password, a Preferences option, a menu which allows you to see your seed words and a light which indicates the status of the wallet – Green means working properly. On the bottom left corner, you can see your current BTC balance.

Send and Receive Assets

In order to send BTC, you must go to the “Send” menu, write down the Address of the receiver (or scan a QR code if available). Below you can write a text description, then you put in the amount you want to send and regulate the fee which will affect how soon the receiver will get his BTC.

When you want to receive BTC send your Receiving Address to the person that will send you coins or let him scan your QR code.

Hint: Always check the addresses several times. Sending is irreversible and not refundable.

Backup and Restore

These vital few step operations form a nice backup option of Electrum, which is accomplishable in several steps. When you initially install and run the wallet, you’ll be asked to create a strong password. The software provides a passphrase of 12 words for safety reasons. Bear in mind, you need to execute just one backup.

When having a backup of Electrum, simply restore it and operate with your assets right away. In case you restore from a seed or backup, make sure the wallet is empty. This is a necessity, because the restoring process overwrites the existing keys with the ones from the restored seed. If not backed up, the previous seed and funds will be lost. For more detailed information on the terms backup and restore cryptocurrency visit the homepage.

Backup

Install and save the seed

In the process of setting up your wallet, you’ll receive a seed, which you should safely store. This is your tool to keep your funds protected, so it’s recommendable to have several copies of it, hidden in multiple different places.

Create a strong password and keep it safe

Creating a reputable password is the key to strongly encrypt your funds. Use capital letters, special symbols and numbers all it one to be sure you’re making a unique and hard to decipher password.

Restore

Install and restore wallet from the seed

If you ever decide to restore your wallet for some reason, you can manage to do it via your pass phrase. You’re simply installing the software and then enter the seed phrase to access your funds.

Restore by importing private keys or using wallet files after install

If the wallet offers no pass phrase, then you have to possess a backup file of it to restore the software. This must be made right after installing the wallet and keeped safe, exactly as your passphrase – multiple copies, on different devices, hidden in several locations.

Hint: HD wallets’ seed generates multiple private key and public address pairs, accessible with this single seed phrase.

Ledger Integration

Have you thought of combining a cold and a hot wallet? Maybe using the offline one to store your coins and the online wallet to operate with them? Well, I can’t wait to tell you about the Ledger-Electrum cooperation. If you buy a Ledger hardware wallet then you can easily set up the Electrum software and use them both. There are several simple steps to follow for the purpose of using the device’s safety and the desktop wallet usability all at once. Check the guide below, if you’re a Windows user:

Step 1: Download and install the Electrum wallet from their official website.

Step 2: When configuring in the installation wizard, choose the ‘Standard wallet’ option.

Step 3: Now connect your Ledger wallet to the PC, enter the PIN and pick the BTC app.

Step 4: Select the ‘Use a hardware device’ function from the list.

Step 5: When the PC initialize the Ledger device, you’ll be asked to enter your ‘Account number’, where you can type simply a zero.

Your device will sync with the software and you can continue using the Electrum wallet. What about Linux users? There are some additional commands to fulfill during the setup process like libraries, if needed. Here they are:

  • apt-get install libusb-1.0-0-dev

  • apt-get install libudev-dev

  • ln -s /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so

  • pip install btchip-python

For the purpose of signing a transaction, you have to validate it on your Ledger device to get it broadcasted in the network. Now, I would like to present you the full list of security and privacy features, so keep reading.

Possible Issues and How to Avoid Them

Let me start by saying, that the setup is fairly hard for a newbie to manage single-handedly. To avoid any inaccuracies along the process it’s advisable to use this guide. Another frequent setback about Electrum is the freezing software. This happens when you try to execute a large number of transactions at the same time. It is advisable to send smaller amounts of BTC to one of your addresses (desired wallets) for verification. Talking about other wallets makes me think of the import of private keys from other BTC wallets. Well, the last version of Electrum doesn’t provide such an option. Basically, you can’t import your private keys in a wallet with a seed. What you can do here is to swap them. Last but not least one advice, make sure you have your password and seed safe. In case of losing or forgetting them, your Electrum account is unreachable.

Troubleshooting Support

Electrum is really active in supporting every user. The users have created a fast responding community reachable at Bitcointalk. One small clarification here, for the forum with questions and support you will have to register. Nothing too complicated. Reddit is one more community forum for such purposes. In case you don’t want to go too deep into the thematic, the common issues are approached in this is official help documentation.

04. About Electrum

Electrum is one of the first invented wallets in the crypto world. It was created by Thomas Voegtlin as a light BTC client in November 2011. Ever since the first day, different developers have contributed to its source code, thanks to the open source character of the product. One of the core features in addition to its BTC decentralized origin is its option to integrate with hardware wallets like Ledger Nano S, TREZOR and KeepKey.

Electrum on Social Media

In the world of crypto, laying hands on every new piece of information is essential. This way you will be able to react on time in case of threat or useful advantage. The team behind Electrum knows that and stays active on several social channels:

Natural electrum 'wires' on quartz, historic specimen from the old Smuggler-Union Mine, Telluride, Colorado, USA
The Pactolus river, from which Lydia obtained electrum for its early coinage
Electrum cup with mythological scenes, a sphinx frieze and the repre­sentation of a king vanquishing his enemies, Cypro-Archaic I, from Idalion, 8th–7th centuries BC (Louvre, Paris)
Brooch with a griffin protome, from the necropolis of Kameiros, Rhodes, c. 625–600 BC (Louvre)

Electrum is a naturally occurring alloy of gold and silver,[1] with trace amounts of copper and other metals. The ancient Greeks called it 'gold' or 'white gold', as opposed to 'refined gold'. Its colour ranges from pale to bright yellow, depending on the proportions of gold and silver. It has been produced artificially, and is also known as 'green gold'.[2]

The gold content of naturally occurring electrum in modern Western Anatolia ranges from 70% to 90%, in contrast to the 45–55% of gold in electrum used in ancient Lydian coinage of the same geographical area. This suggests that one reason for the invention of coinage in that area was to increase the profits from seigniorage by issuing currency with a lower gold content than the commonly circulating metal. (See also debasement.)

Electrum was used as early as the third millennium BC in Old Kingdom of Egypt, sometimes as an exterior coating to the pyramidions atop ancient Egyptianpyramids and obelisks. It was also used in the making of ancient drinking vessels. The first metal coins ever made were of electrum and date back to the end of the 7th century or the beginning of the 6th century BC. For several decades, the medals awarded with the Nobel Prize have been made of gold-plated green gold.

Etymology[edit]

The name 'electrum' is the Latinized form of the Greek word ἤλεκτρον (ḗlektron), mentioned in the Odyssey referring to a metallic substance consisting of gold alloyed with silver. The same word was also used for the substance amber, likely because of the pale yellow colour of certain varieties.[1] It is from electrum’s electrostatic properties that the modern English words 'electron' and 'electricity' are derived. Electrum was often referred to as 'white gold' in ancient times, but could be more accurately described as 'pale gold', as it is usually pale yellow or yellowish-white in colour. The modern use of the term white gold usually concerns gold alloyed with any one or a combination of nickel, silver, platinum and palladium to produce a silver-coloured gold.

Composition[edit]

Electrum consists primarily of gold and silver but is sometimes found with traces of platinum, copper, and other metals. The name is mostly applied informally to compositions between about 20–80% gold and 20–80% silver atoms, but these are strictly called gold or silver depending on the dominant element. Analysis of the composition of electrum in ancient Greek coinage dating from about 600 BC shows that the gold content was about 55.5% in the coinage issued by Phocaea. In the early classical period, the gold content of electrum ranged from 46% in Phokaia to 43% in Mytilene. In later coinage from these areas, dating to 326 BC, the gold content averaged 40% to 41%. In the Hellenistic period, electrum coins with a regularly decreasing proportion of gold were issued by the Carthaginians. In the later Eastern Roman Empire controlled from Constantinople, the purity of the gold coinage was reduced, and an alloy that can be called electrum began to be used.

History[edit]

Electrum is mentioned in an account of an expedition sent by Pharaoh Sahure of the Fifth Dynasty of Egypt. It is also discussed by Pliny the Elder in his Naturalis Historia. Electrum is also mentioned in the Hebrew Scriptures, whose prophet Ezekiel is said to have had a vision of Jehovah on a celestial chariot (Ezekiel 1:4).

Early coinage[edit]

The earliest known electrum coins, Lydian and East Greek coins found under the Temple of Artemis at Ephesus, are currently dated to the last quarter of the 7th century BC (625–600 BC).[3] Electrum is believed to have been used in coins c. 600 BC in Lydia during the reign of Alyattes.[4]

Electrum was much better for coinage than gold, mostly because it was harder and more durable, but also because techniques for refining gold were not widespread at the time. The discrepancy between gold content of electrum from modern Western Anatolia (70–90%) and ancient Lydian coinage (45–55%) suggests that the Lydians had already solved the refining technology for silver and were adding refined silver to the local native electrum some decades before introducing the pure silver coins cited below.[5]

In Lydia, electrum was minted into coins weighing 4.7 grams (0.17 oz), each valued at ​13stater (meaning 'standard'). Three of these coins—with a weight of about 14.1 grams (0.50 oz)—totaled one stater, about one month's pay for a soldier. To complement the stater, fractions were made: the trite (third), the hekte (sixth), and so forth, including ​124 of a stater, and even down to ​148 and ​196 of a stater. The ​196 stater was only about 0.14 grams (0.0049 oz) to 0.15 grams (0.0053 oz). Larger denominations, such as a one stater coin, were minted as well.

Because of variation in the composition of electrum, it was difficult to determine the exact worth of each coin. Widespread trading was hampered by this problem, as the intrinsic value of each electrum coin could not be easily determined.[4]

These difficulties were eliminated circa 570 BC when the Croeseids, coins of pure gold and silver, were introduced.[4] However, electrum currency remained common until approximately 350 BC. The simplest reason for this was that, because of the gold content, one 14.1 gram stater was worth as much as ten 14.1 gram silver pieces.

  • Electrum trite of Alyattes of Lydia, 610–560 BC

  • Electrum coin from Cyzicus, Mysia, early–mid 4th century BC
