How to Store Bitcoin: free multicurrency wallet

If you are a newbie, maybe you are asking yourself the following question: how to store Bitcoin? Which is the safer and cheapest wallet on the web? Why should I open a multicurrency wallet?

Well, today I want to answer people who are trying to start using Bitcoin and cryptocurrencies in general.

First of all, wallet stores a private key that you need to access a bitcoin address for storing and spending your digital currencies.

Bitcoin is a distributed and revolutionary method of payment also defined as Internet of Money as it is a virtual currency without any physical attribution.

So, how to store Bitcoin? We store fiat cash in a physical wallet and Bitcoin works in a similar way, as you will need a virtual wallet.

As well as Euro or Dollar are physical and should be stored in a physical wallet, so bitcoin are virtual and shall be kept in an equally virtual wallet.

If I have to be more specific, you don’t technically store bitcoin anywhere. What you store is the secure digital key you need to have in order to access your public bitcoin addresses and execute transactions.

How to store Bitcoin in a Web wallet

HolyTransaction is a web wallet where you can store your private keys online, on a computer, and connected to the Internet, of course.

One of the main advantages of a web wallet is that you can access them from anywhere and on any device you are using.

Security and Privacy

To create your web wallet you just have to enter your email address. You don’t need to have a bank account or send your ID card, so you can set up it in just one minute.

One way to protect your wallet is encryptit it with a strong password. This will make it difficult to access to your funds.

Another method is doing a back up. To do so, you need to copy your private keys.

Also, you can use a two factor authentication code. In this case you should download a free app called “Google Authenticator” on your mobile phone and scan the QR code obtained. Then everytime you need to execute a transaction you’ll have to enter the two-factor authentication code. And, of course, this will make your wallet safer.

Multicurrency Wallet

A Multicurrency wallet is a virtual wallet where you can store different kinds of digital currencies within the same place.

If you have multiple cryptocurrencies, you typically have to manage multiple wallets for each one. This could be a time consuming task. With HolyTransaction, since it supports several digital currencies, you don’t have to manage a few wallets and you can just log into one wallet and toggle between them in one user interface, making the task much easier.

So, with just one registration and only one password to remember, you can store not only Bitcoin but also the other major cryptocurrencies such as Blackcoin, Dogecoin, Dash, TetherUS, Ethereum and Peercoin.

US Department Homeland Security uses Blockchain

<img src="/images/usdepartmenthomelandsecurityusesblockchain.jpg" alt="US Department Homeland Security uses Blockchain" height="264" width="350" />

The division created after the 9/11 terrorist attacks, US department Homeland Security (DHS) uses blockchain technology to solve security issues.

First announced in a press release published in December, the DHS announced in June that it awarded a prize of $199,000 to the blockchain startup Factom that aims at using the distributed ledger to ensure the security of cameras that monitor US borders.

How US Homeland Security uses Blockchain

This way the blockchain could be helpful for DHS as it aims at building an identity for devices, or a way to extend the company’s ability to monitoring services and devices.

Data privacy program manager Anil John explained to Coindesk:

“The Factom piece is more along the line of these devices exist, but how do we build a picture of the identity of this device over time? The blockchain could be the catalyst that allow us to document the changes”.

Also, he explained that the company wants to learn more about the potential applications of the blockchain.

“For DHS use cases, the projects we’re funding are focused on proving or disproving that security and privacy can be supported by a blockchain-based infrastructure. It is much broader than IoT and identity.”

To do so, DHS gave funding also to projects such as Solarity Solutions, Respect Network and Digital Bazaar.

Universal Wallet

To store in a safe place your digital currencies you need a good wallet such as the one provided by HolyTransaction.

We define it as a “Universal Wallet” as you can store different kinds of digital currencies in a single account.

In the HolyTransaction wallet, in fact, you can store Bitcoin, Ethereum, Dogecoin, Peercoin, Blackcoin and Litecoin in a single account easy to manage.

Bitcoin, the trust chain that banks and governments cannot corrupt

bitcoin_blockchain

Bitcoin is a trustless money

For centuries the use of money evolved according to available technologies and society needs. Bitcoin is a currency and each currency is information. 
The information must be exchanged, only this way it can be recognized and associated with a value, especially in today’s world drawn as a network.

How trust can be betrayed

Problems arise when – while exchanging information – there are intermediaries who betray the trust, for example: 
1 .central banks, if it inflates the currency (es. quantitative easing, or a tool to inject more liquidity into the market in order to indirectly encourage households and consumer businesses);
2. banks, if they fail, taking away our funds on current accounts (see bail-in or, in case of failure, no longer pays the state, but shareholders , creditors and depositors);
3. governments, if it confiscates assets or block transfers (Amato government in ’92) ;
4. national currency, if it is accepted everywhere (or if it is excluded from a stronger system, for example euro ) ;
5. privacy, if it is violated during the online shopping;
Whoever believes in a cryptocurrency such as bitcoin, knows that history (Argentina, Cyprus, Greece, etc.) has already shown that it is not possible to have confidence in all these linked subjects, because each one carries its own interests.
A centralized entity can actually change, omit or delete any data that passes through its control, since in these entities work people that have a corruptible nature.

What is the “pre-trust” ?


Now, not only friction, costs and transaction times can be reduced, but corruption can be eliminated too. It is virtually impossible to corrupt the ledger: you cannot write on it, and you cannot change what other people write on it: it is no longer a human job.
So, if there is no trust, to have a secure system we need a network that can perform an action associated with a cost. Since you don’t know the other person you are exchanging the value ​​with you have to “pre-trust” in 3 basic elements: mathematicians, economists, technicians. 
1. Mathematicians, with the asymmetric encryption, or the concept of public and private keys, you need to certify who is the true owner of the property;
2. Technicians, with the network that reaches consensus through the “proof-of-work” system, and valid the transactions before they are permanently written onto the blockchain, so it is no longer possible to repeat the processing fraudulently (thus solving the problem of double spending)
3. Economists, because of the incentive to earn money with bitcoin. For these reasons a public blockchain cannot live without the use of bitcoin if we want to have its maximum security .
All the above systems are designed to work together without the need for intermediaries.
Now people are starting to use cryptocurrencies, such as Bitcoin, as a method of payment and at the same time entities that accept it are spreading quickly.
On CoinMap you can see the map of all the places where these exchanges take place. And, what is the infrastructure that supports this exchange? The blockchain.


Blockchain, the infrastructure that runs bitcoin


The blockchain – to define it in simple terms – is a timestamp, so it is only a consequence. The important thing is the protocol, the safe encryption with which transactions are signed. 
It is not important the account balance, but how reliable is that publicly available data. 

So far, paradoxically, it relied on the piece of paper in the hands of anyone. But the paper documents are now easily forged, to be trusted more if we read the declaration of property on blockchain .
Lavoiser stated: “Nothing is created, nothing is lost , everything is transformed .” 
But it was a law that applies only to the material world . For the digital world , in blockchain format , the new law is : “Everything is created , nothing is lost , nothing can be changed.”

Blockchain to be used on the battlefields by Darpa

darpa blockchain

The most popular research projects agency for defence, better known as Darpa, is studying a method to create a blockchain-based messaging platform to be used for battlefield objectives.

This DARPA’s project is still just an idea, but it comes out thanks to a website post on its official websites. 
DARPA became very popular thanks to its revolutionary ideas and its goal of promoting emerging technologies. 
In fact, back in the ’60s, DARPA created ARPANET, a primitive form of what today we call Internet. 

The press release

According to the official press release, DARPA aims at creating a”secure messaging system” using a “decentralized ledger” to allow encrypted secrets. 
The press release explains:
“There is a critical DoD need to develop a secure messaging and transaction platform accessible via web browser or standalone native application. The platform separates the message creation, from the transfer of the message within a secure courier to the reception and decryption of the message.”

The 3-steps model

DARPA believes it will need 3 stages to bring the project to reality.
  1. Development: “built on the framework of an existing blockchain framework”, using the blockchain as a model;
  2. Creation of prototypes and commercial-scale versions of the network;
  3. Deployment

Applications

According to DARPA, this system can be used within the DoD offices to interact in a secure way.
“By doing this, significant portions of the DoD back office infrastructure can be decentralized, smart documents and contracts can be instantly and securely sent and received thereby reducing exposure to hackers and reducing needless delays in DoD back office correspondence. As an example, Military Interdepartmental Purchase Requests (MIPR) could be implemented using the secure ledger.”
The system could be also used for battlefield applications.
“Troops on the ground in denied communications environments would have a way to securely communicate back to HQ, and DoD back office executives could rest assured that their logistics system is efficient, timely and safe from hackers”.

BNP Paribas to develop a blockchain project

Today BNP Paribas Group has announced a new partnership that aims at allowing private companies to issue securities through the blockchain ledger.

The partnership is between BNP Paribas Securities Services and SmartAngels, a crowdfunding platform that will help BNP Paribas in a pilot project to be launched within the end of 2016.
According to a press release, BNP Paribas will develope and manage a ledger for shares in companies through the blockchain.
The main goal is to allow non-listed companies crowdfunded on SmartAngels to issue their shares on the primary market, and allow investors an access to the secondary market based on blockchain technology. 
The BNP press release explained:
“Investor payments will be processed immediately and e-certificates will be issued to them straight away. Financial transactions made via the platform will therefore be performed simply, quickly, securely and for a lower cost.”

BNP Paribas believes in the Blockchain

BNP Paribas is not new in the blockchain sector.
A few months ago, in fact, BNP confirmed its belief in distributed ledger technology for financial purposes and announced that they were working on blockchain technology.
Also, BNP Paribas previously created their blockchain Bizhackathon, with the objectives of finding use cases for distributed ledger technology in the banking system.

How the blockchain could help email security

BitMessage

Every day we send thousands of emails and such communication has become a daily routine and a MUST for any person and company.

But options to secure communications are not so common and strong. Also, the existing services are too difficult for people to use and they should use a trusted channel.

  
This is the reason why it has been opened the open source project called BitMessage, a service who helps to decentralize and encrypt messages and solves the problem of trusting a third party security authority. 
But BitMessage doesn’t use the bitcoin blockchain, but a distributed ledger created by the BitMessage Community itself. 

How it works

Thanks to BitMessage and its wallet, you will be able to create a private key and your contacts will receive a string that look like a bitcoin address. 
This way you will have a long alphanumeric string among your contact lists instead of email addresses, and you need a proof-of-work to send your message, even offline. 
In fact, BitMessage proposes a system where customer uses a hash of a public key that it is the same as the user’s address. “If the public key can be obtained by the underlying protocol, then it can easily be hashed to verify that it belongs to the intended recipient. The data exchanged by the user can also include a version number for forwards capability, a stream number and a checksum”, explained the whitepaper. 

Here you can read the full whitepaper, in which BitMessage is described as a “peer-to-peer message authentication and delivery system” platform.


The invention

BitMessage was opened in November 2012 by Jonhatan Warren, who also created PyBitmessage, or the official instant messaging client for BitMessage.

Technical details

Its source code use Python as a language and the Qt cross-platform application framework; OpenSSL allows its cryptographic functions. BitMessage is available for Microsoft Windows, Mac OS and Linux.
Unfortunately, it is not available for mobile devices.
